I have a model Book with a has_many relationship to State.
class Book < ActiveRecord::Base
has_many :states
...
end
State sets the visibility of the book to "private", "restricted" or "public" through a name attribute. For auditing purposes, we keep a record of all state changes so to get the current state of a book I use
> book = Book.first
> book.states.last.name
> "public"
Now I need to query on all Book objects where the current state is public.
Something along the lines of:
Book.joins(:visibility_states).where(states: { state: "public"})
The problem is that the query above return all books that are currently pubic, or have been public in the past. I only want it to return books that are currently "public" (i.e. book.states.last.name == "public").
I know I can do it with select but that's generating one query for each record:
Book.all.select { |b| b.states.last.name == "public" }
Is there a way to do it using ActiveRecord only?
I am using JIRA api to extract timespent by users on issues. The time spent is in the format:
"12w 1d 2h 5m" or "12h" or "12m" etc
The API isn't exporting the number of hours. Is there a quick (requires no effort on my part) way to convert this to hours (or seconds). I suppose this is some sort of a standard format, is there a name for it? I know how to do this myself, just don't want to reinvent the wheel
I am getting the highly poular message:
** Notice: The native BSON extension was not loaded. **
For optimal performance, use of the BSON extension is recommended.
To enable the extension make sure ENV['BSON_EXT_DISABLED'] is not set

If you continue to receive this message after installing, make sure that
the bson_ext gem is in your load path.
I am running rbenv and have tried gem install bson_ext. I get no errors - it tells me Successfully installed bson_ext-1.12.3. However bson_ext is not found - I assume its an executable. How do I know where it should be installed so that I can update my path accordingly?

I'm building a gem. I just got the basic project structure laid out, and I tried building it with gem build my_gem.gemspec, which worked fine. Then I installed it with gem install My\ Gem-0.0.1.gem and it still looked like it worked fine. Then I tried to run irb and I got this:
/Users/<username>/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rubygems/version.rb:206:in `initialize': Malformed version number string on (ArgumentError)
Then I tried making some changes and saved them. I ran gem build my_gem.gemspec. Same error. All irb, rails, and gem sub-commands are generating a stack trace with this at the top. What did I do to break all of these commands and how do I reverse it?
I have a Chef recipe in which I am creating a new randomly named user using a shell script and exporting the username as a variable. Is it possible to set the same user as a session variable in Ruby? Something like...
ENV['CHEFUSER'] = 'echo $CHEFUSER'
which does not work unfortunately. Or any way to pass environment variables from bash to ruby. I need this new user to be recognized in the same recipe in which it was created.
Thanks, sorry if this has been addressed, I could not find any info on it.
I am using paperclip gem along with an AWS s3 bucket to upload images to my app. I have it all working properly and the images will upload to the actual bucket and the web pages will load. The only problem is the images themselves will not display and it will only display their names like
to display the image I am using the code
<%= image_tag @post.image.url(:medium), class: "edit_recipe_image" %>
has any one experiences this before or possibly know a solution to fix this?
Thanks in advance!
Very new to Ruby and cucumber, and i've got a controller that accepts an ID. Basically a rest API, so the client would call /cows/1234 and /cows/777. That would then route to getFluffyCow and pass :id = 1234 or 777.
My initial attempt is as follows:
allow(getFluffyCow).to receive(:call).with(1234).and_return(mock_cow1)
allow(getFluffyCow).to receive(:call).with(777).and_return(mock_cow2)
but the response is returning nothing. What am I doing wrong?
Thanks!

I have been trying to find out the reason, after wondering around I found out about change in rails 4.0.0 in that attr_accessible are no longer used and we should use strong parameter instead, So removing the attr_accessible from model will solve the problem...
However, I have an empty Model, there is no attr_accessible everywhere i look. (beside this is weird why my apps runs locally but not on heroku?) I can't figured out why this error appear and where to look for solutions.. I have been trying to look at active_record file but am afraid of making any changes, any idea?
also, could anyone tell me any resources that can help me read this type of log errors? I have tried to read some articles but can't find one that is easy to understand for noobs like me... ;(
I have two arrays, one containing hashes, the other integers. They look like this (samples):
mainArray[0] = {"ID" => 23, "NAME" => "SALLY"}
mainArray[1] = {"ID" => 34, "NAME" => "BILL"}
idArray[0] = 432
idArray[1] = 34
I want to filter mainArray so that only entries in it whose ID values are in idArray make the cut. How can I best do this? I don't mind making a new array if that helps.
I have a DLL which contains code that I would like to access from Microsoft Visual Foxpro as well as Ruby on Rails.
I set up a C# DLL and generated the corresponding .so file using Mono according to this question. mono --aot -O=all dlltest.so
As noted in that question, the function nm -Ca dlltest.so shows a form of my method, but FFI cannot see it.
Also as mentioned in that question, nm -D --defined-only dlltest.so indicates that my method is not defined. However, FFI can see and access the one that is defined as mono_aot_file_info.
It seems like the poster of that question was close to getting it to work, but I was unable to find anything about why the method is showing as not defined or how to change that.
Is there something I can do to define the methods in the .so file? Or is this not possible?
Note that the method is exposed in the DLL, and FoxPro can access it just fine.
I am building a Ruby on Rails webapp and it is great for the web front end, display, what the user sees etc. But I want request from a user that involves some heavy processing to be done inside a Java backend layer.
So my question what do you think is the best approach for joining these two layers up? I can think of two approaches:
Building up the request into a JSON object in the Ruby on Rails layer and using RabbitMQ to send it as a message to the Java backend layer which sends another JSON object back in a message as a response. I tend to lean more towards this approach as there a nice RabbitMQ clients for Ruby and Java.
Have a my Java layer running on a web server(such as Tomcat or maybe Netty?) that accepts HTTP requests from the Ruby on Rails layer and sends the response back through the server using HTTP?
Note any persistence will be handled by the Java layer also.
Any more ideas or and/or comments on the above two ideas would be great.
Thanks.
In IntelliJ IDEA, or Eclipse, while working with java I am able to reset the current stack frame while debugging. For example, if I am debugging a method and I make some changes or want to go back and look something over I can reset the current stack frame and the debug pointer will go back to the beginning of the method. Is there anything like that in RubyMine?
Currently my home page (index.html.erb) shows all the user images loaded within the past 24 hours, which is part of posts. However I would like to add a form that allows the user to sort images based on their category and upload date. (For example images with the category music, uploaded within the past month) I understand how to query the database but I dont know how to take the user input. When I create a form, suing simple form: <%= simple_form_for @posts do |f| %>, it throws an error, saying I cannot use an object. Ive thought about ajax but it doesnt seem to work well with the paperclip gem, plus I rather get it done on the backend. I hope my issue well enough. If not feel free to comment as I will be around to respond. Thanks in advance.
Post Controller:
def index
@posts = Post.all.where(created_at:(Time.now - 1.day)..Time.now)
end
Schema for Post table:
create_table "posts", force: :cascade do |t|
t.string "title"
t.string "instagram"
t.text "description"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "user_id"
t.string "image_file_name"
t.string "image_content_type"
t.integer "image_file_size"
t.datetime "image_updated_at"
I am trying to use the numeric charecters from the array held within the positions argument as indices to access the characters of the string inside the string argument to subsequently print a new string. I have an idea of what I need to do to get it to work, but I am hung up.
Total code thus far:
def scramble_string(string, positions)
str = string
pos = positions.join
newstr = []
i = 0
while i < pos.length do
return newstr.push(str[pos[i]])
i += 1
end
end
scramble_string("hello", [2, 3, 4, 5])
I suspect my problem lies within this part of the code...
return newstr.push(str[pos[i]])
I need to get the NT (native) path of a file from the DOS (Win32) path in Ruby (1.9.3).
Meaning, I have the string:
dos_path = "C:\Windows\regedit.exe"
but I need:
nt_path = "\Device\HarddiskVolume1\Windows\regedit.exe"
Is there any way to do so? Thanks!
Someone told me that the reason why Ruby does not implement abstract classes (you have to implement it yourself using some intelligent tricks) is that it isn't strongly typed. Can anybody explain that to me?
I installed Ruby via the official installer, installed the non x64 version just in case. Then I tried to install sass via the command line like on the http://ift.tt/1f0fI2t page, The following ensued:

Fetching: sass-3.4.16.gem (100%)
ERROR: While executing gem ... (Errno::EACCES)

Any ideas what could be causing this?
I'm trying to figure out a better way to have one query here. I want to be able to send something to last where statement a wildcard so I can select all vendors. Right now if i don't include that line it doesn't filter by vendor so I essentially get all the purchase requests.
Any thoughts of a cleaner way to do these sorts of queries?
if @vendor == "0" #checks for vendor
@purchase_requests = PurchaseRequest.includes(:purchase_order)
.where(:created_at => @date_start..@date_end)
.where(:total_cost => @cost_beginning..@cost_end)
else
@purchase_requests = PurchaseRequest.includes(:purchase_order)
.where(:created_at => @date_start..@date_end)
.where(:total_cost => @cost_beginning..@cost_end)
.where("purchaseorder.VendorRef_ListID = ?", @vendor)
end
I am in the process of trying to iterate over a ruby hash. I'll have to admit that my knowledge of ruby is very poor and i am in the process of trying to correct that, and so please bear with me if this is a very elementary question.
I am wondering if the syntax of my hash is off. The reason why it is looking the way that it is is because it is part of a rakefile, and i need to incorporate multiple addresses in this. (which i've never done, i've always only had 1 address to worry about) I know the solution to this is to build the addresses in as a rakefile, and then loop over them.
clinic.build_address.each do | build_address |
{
(city: "Minneapolis"
state: "MN"
address1: "316 10th ave"
zip: "55414"),
(city: "Hudson"
state: "WI"
address1: "119 Belmont Street"
zip: "54016")
}
With what I have right now I am getting an unexpected label (it is not liking that I have 'city:minneapolis')
Would anybody be able to take a quick look at what I have with this?
I am making a small game at the moment, and want it to be possible for users to save their characters, which will likely be stored in a text file. Is there any way to make this text file inaccessible to the user in the windows explorer or whathaveyou, so that save tampering is impossible (or at least harder), but also accessible to my program?

I'm working on a Middleman (Ruby) site. There are data objects which are instances of Thor::CoreExt::HashWithIndifferentAccess. However, it seems whenever I call try that I get nil.
I see that Thor::CoreExt::HashWithIndifferentAccess takes advantage of method_missing. Does this break how try works? Is anyone able to replicate this?
UPDATE: Here's a simple example. I'm using Middleman which provides access to data files.
# /data/people.yml
jane:
name: Jane Doe
age: 25
john:
name: John Doe
age: 25
Then in a template you have access to the data.people method which returns a Thor::CoreExt::HashWithIndifferentAccess instance:
data.people.inspect
#=> {"jane"=>{"name"=>"Jane Doe", "age"=>25},"john"=>{"name"=>"John Doe", "age"=>25}}
data.people.class
#=> Thor::CoreExt::HashWithIndifferentAccess
Now when I call try on anything I get nil:
data.people.jane
#=> {"name"=>"Jane Doe", "age"=>25}
data.people.try('jane')
#=> nil
data.people.try(:jane)
#=> nil
data.people.try(:something_that_does_not_exist)
#=> nil
data.people.jane.try(:name)
#=> nil
I'm running tests in Ruby Mine 2.7.1 using Page-Object + Rspec.
Environment: Windows 7 x64, Ruby 1.9.3 p551, IE 11.
Gems: watir, rspec, bundler, page-object
When i run tests in Chrome or Firefox everything is ok.
But when i try to run them in IE, the IE window with correct page gets opened and after that i get an error specified in Subject: "Watir::Exception::NoMatchingWindowFoundException: browser window was closed"
The point is that the browser is actually open at that moment and shows a correct page. (See the screencast showing what happens: http://ift.tt/1hhIBzU)
Test gets finished with an error and the config.after do section doesn't get executed because the browser window remains opened.
That error happens when the following code is executed:
before(:each) do
visit <ClassName>
end
Seems like the IEDriverServer loses connection with IE right after the page is opened.
The most confusing this is that in very rare cases, everything is working good, and in even more rare cases everything is working with significant slowdowns with timeout error at the end.
sleep <n> delays don't help.
I tried different versions of selenium-webdriver gem (it is required by watir gem), different versions of IEDriverServer for both x86 and x64 platforms - result is the same.
What do i do to set IEDriverServer not to lose the IE browser?

I want to know if something like this is possible, as hash.each does two different things based on arguments passed to block
{ "a"=>3, "b"=>2}.each {|k| puts k}
{ "a"=>3, "b"=>2}.each {|k,v| puts k}
Both output different things, and not just what's below..
a
b
..
a
b
i get this
a
3
b
2
..
a
b
So i want to know if there is a way to get my function to do something custom depending on the number of arguments of block being passed to it.
like this
def my_method do
if yield.args==2
yield("hi","bro")
else
yield("what's up")
end
end
my_method {|a,b| puts a; puts b;} //"hi" "bro"
my_method {|a| puts a; } //"whats up"
I have the following line in my routes.rb (Rails 4.1.4):
resources :request_caches
However, when I run rake routes I get the following output:
request_caches GET /request_caches(.:format) request_caches#index
POST /request_caches(.:format) request_caches#create
new_request_cach GET /request_caches/new(.:format) request_caches#new
edit_request_cach GET /request_caches/:id/edit(.:format) request_caches#edit
request_cach GET /request_caches/:id(.:format) request_caches#show
PATCH /request_caches/:id(.:format) request_caches#update
PUT /request_caches/:id(.:format) request_caches#update
DELETE /request_caches/:id(.:format) request_caches#destroy
As you can see, Rails somehow maps request_caches plural to request_cach singular. But it should be request_cache. Is this some kind of special case, because of the word caches? I've also played around with
resources :request_caches, as: :request_cache
But this results in wrong routes like request_cache_index. And furthermore, I think this is a standard task and should be solved clearly using Rails intern route helpers.
So, what am I doing wrong?
I know how Forwardable#def_delegate works with methods on objects, but is there a similar way to forward methods names to hash keys. Like:
hash = { some_value: 42, other_value: 31415 }
def_delegate :hash, :some_value, :other_value
Calling object.some_value should return 42
PS: def and class eval is a way, but is there a nicer way?
I am trying to solve this problem
Given a sentence containing multiple words, find the frequency of a given word in that sentence.
Construct a method named 'find_frequency' which accepts two arguments 'sentence' and 'word', both of which are String objects.
Example: The method, given 'Ruby is The best language in the World' and 'the', should return 2 (comparison should be case-insensitive).
Hint: You can use the method
Array#countto count the frequency of any element in the given array.
Since the comparison should be case-insensitive. I use these code to help:
word = "the"
word_set = []
word.size.times do |i|
word[i] = word[i].upcase
word_set << word
word[i] = word[i].downcase
end
Inside the block every time after upcase method the word does change and does add to the word_set, however when the block finish the word_set just contain the the the What is the problem?

I want to create a Facebook style inbox page that allows a user to scroll through their Inbox, Sent Items and Trash, whilst keeping the selected conversation displayed on the right hand side of the page (like Facebook's implementation of the desktop inbox)
The action of clicking the conversation title should render that entire conversation to the right side of the page, avoiding the need of dedicating an entire page to one conversation within the web browser. This is so (in a later version) I can implement an AJAX call that will only refresh the conversation part of the page, whilst allowing the user to keep an eye on their conversation list.
My problem is, I'm completely stumped as to how this would be implemented, without the routing error No route matches [GET] "/conversations/20/show_conversation" that I'm currently getting. I'm fairly new to Ruby on Rails, so the whole routing side of things is a bit confusing.
My question how do I display all my conversations, as well as the transcript of one selected conversation (at any given time) on the same page. Preferably, I would like to avoid the use of Javascript/ jQuery and stick to the Ruby on Rails implementation, if possible.
Here's a screenshot of my "messages" page, where "Conversation.." (on the right) should display the transcript of the conversation I had with the target user.
My controller code for the current page:
class ConversationsController < ApplicationController
before_filter :authenticate_user!
before_filter :get_mailbox
before_filter :get_conversation, except: [:index]
before_filter :get_box, only: [:index]
before_filter :get_conversation, except: [:index, :empty_trash]
def index
@conversations = @mailbox.inbox.paginate(page: params[:page], per_page: 10)
@inbox = @mailbox.inbox.paginate(page: params[:page], per_page: 10)
@trash = @mailbox.trash.paginate(page: params[:page], per_page: 10)
@sent = @mailbox.sentbox.paginate(page: params[:page], per_page: 10)

I do have a working conversation partial that builds the conversation on a separate page. It works fine, but I haven't included it because I want to move away from having a separate page to view the conversation. Any help on this would be greatly appreciated!
Thanks,
I am using the ruby-zbar gem in a rails app to scan barcodes from jpgs. I installed the zbar library using homebrew on my local machine and everything works fine. However, when deploying to Heroku I consistently get errors such as the following:
remote: LoadError: Didn't find libzbar on your system
remote: Please install zbar (http://ift.tt/refsyg) or set ZBAR_LIB if it's in a weird place
remote: FFI::Library::ffi_lib() failed with error: library names list must not be empty
I've tried following the advice from this Stack Overflow post (Heroku Zbar Didn't find libzbar on your system (LoadError)), namely to set the ZBAR_LIB ENV variable to /app/vendor/lib/libzbar.so, or failing that to run heroku bash and try to find a file named libzbar.so and point ZBAR_LIB to its path.
However, I can't seem to find the heroku buildpack referenced in the original Stack Overflow post (the link to http://ift.tt/1mpaR2J goes to a 404 page), so I can't replicate the solution outlined there.
I have tried all of the following buildpacks:
http://ift.tt/1ImOq5Q
http://ift.tt/1KO1BT3
http://ift.tt/1ImOsdY
During the build process I can see hopeful messages like this:
remote: -----> Multipack app detected
remote: -----> Fetching custom git buildpack... done
remote: -----> ZBAR app detected
remote: -----> Downloading and installing ZBAR
remote: -----> Configuring ZBAR
remote: -----> Make!
remote: -----> Make install !!!
remote: -----> Writing profile script
remote: -----> Fetching custom git buildpack... done
remote: -----> Ruby app detected
remote: -----> Compiling Ruby/Rails
remote: -----> Using Ruby version: ruby-2.2.1
But setting ZBAR_LIB to /app/vendor/lib/libzbar.so gives me some version of this error:
remote: LoadError: Didn't find libzbar on your system
remote: Please install zbar (http://ift.tt/refsyg) or set ZBAR_LIB if it's in a weird place
remote: FFI::Library::ffi_lib() failed with error: Could not open library '/app/vendor/lib/libzbar.so': /app/vendor/lib/libzbar.so: cannot open shared object file: No such file or directory
And trying to find libzbar.so on heroku run bash has not been successful for me -- I can see many files that are similar in name (even a libzbar.rc) but none that fits the bill.

Has anyone had success getting zbar to run on heroku? If so, what buildpack did you use? I would be thrilled to learn how to make this work.
ps aux | grep elasticsearchcd app/currect && RAILS_ENV=production bin/rails cUser.import
Output:
Scoped order and limit are ignored, it's forced to be batch order and batch size
User Load (0.4ms) SELECT "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT 10
Faraday::ConnectionFailed: connection refused: localhost:9200
Elasticsearch stopped and import doesn't work, why ?
I am using Ubuntu 14, Puma server, SQLite database. Does it matter?
Additional notes:
http://ift.tt/1P3OOuv - gemfile.lock from project
http://ift.tt/1IVORti - elasticsearch config
http://ift.tt/1P3OOux - elasticsearch log
Before User.import
ps aux | grep elasticsearch
shows elasticsearch process
After User.import ps aux | grep elasticsearch doesn't show process
How to check if elasticsearch uses 9200 port ?
I'd like to know the definition of method from a huge github repository (say from example i want to see the definition of super method in this github repository).
Are there any tools to do it quickly?
I'm new in Ruby (and in developing too) and I would like to get the response from another url (my url) in the get method.
i'm using rest-client gem.
I have tried this code:
class UsersController < ApplicationController require 'rest-client' def index
RestClient::Request.execute( method: :get, url: 'https://my-url')
end
end
but when I open http://localhost:3000/users I get a blank page
Thanks in advance,
Joel
I'm wanting to create a pair of classes. The second of the pair sub-classes the first, is nested within the first, and only has the addition of being an Enumerator. Like so:
MyClass # this is the parent class
MyClass::Enumerator # it has an Enumerator which sub-classes MyClass
Further to this, when sub-classing MyClass, the subclass should get its own iterator which is also nested within it. Like so:
MySubClass = Class.new(MyClass) # This class sub-classes MyClass
MySubClass::Enumerator # It has an Enumerator which sub-classes MySubClass
I've actually created the code and it works, but I'm wondering if there is a better way or an existing design pattern to achieve this. The code I've written to make this work is the following:
module EnumerableCompanionClass
extend ActiveSupport::Concern
# this ensures the parent class gets it's companion class
included { create_enumerable_class }
module ClassMethods
# this ensures an descendants get their companion class
def inherited(sub)
# need to make sure this doesn't get called for the companion class.
# at this point it's still an anonymous class
# this is to stop infinite recursion
unless sub.name.blank? || sub < Enumerable
sub.create_enumerable_class
end
end
def create_enumerable_class
# only create the companion class once
@enumerable_class ||=
# create the companion class as a subclass of the current class
# but only if self is a class (not a module) and is not the companion class
if self.is_a?(Class) && !(self < Enumerable)
enumerable_class = Class.new(self) do
include ::Enumerable
# my custom each method
def each(&block); end
end
# define a constant for the companion class
const_set('Enumerable', enumerable_class)
end
end
end
end
And this is the code to check that it works as expected:
class A
include EnumerableCompanionClass
def test1; 'this should work!'; end
end
A::Enumerable.parent == A # true
A::Enumerable.new.test1 # 'this should work!'
class B < A
def test2; 'this should also work'; end
end
B::Enumerable.parent == B # true
B::Enumerable.new.test1 # 'this should work!'
B::Enumerable.new.test2 # 'this should also work'
class C < B
def test3; 'this should triple work'; end
end
C::Enumerable.parent == C # true
C::Enumerable.new.test1 # 'this should work!'
C::Enumerable.new.test2 # 'this should also work'
C::Enumerable.new.test3 # 'this should triple work'
So as you can see from the output, it all works as expected.
But it's messy and not very intuitive. For starters, the included method is only there for the parent. Likewise, the inherited method is only there for the sub-classes. The checks for anonymous classes and unnamed classes are there to prevent infinite recursion (we don't want the Enumerator classes to have it's own Enumerator).
I'm happy that it works but I'm sure there has to be a better way. I've tried other methods and this is the only one that I've gotten to work correctly so far.
Does any one know the canonical way to achieve this, or a better design pattern?
Thanks in advance!
[EDIT]: added a github issue
some infos about versions:
ruby 2.2.2 rails 4.1.12 vanity (2.0.0.beta8) - from master branch on github
I followed the guide at http://ift.tt/Sin99n . I did all the steps, I'm using activerecord adapter to connect to the db. I implemented the following example in the guide:
Step 2: Define your first A/B test
This experiment goes in the file experiments/price_options.rb:
ab_test "Price options" do
description "Mirror, mirror on the wall, who's the better price of all?"
alternatives 19, 25, 29
metrics :signups
end
If the experiment uses a metric as above (“signups”), there needs to be a corresponding ruby file for that metric, experiments/metrics/signups.rb.
metric "Signup (Activation)" do
description "Measures how many people signed up for our awesome service."
end
Step 3: Present the different options to your users
<h2>Get started for only $<%= ab_test :price_options %> a month!</h2>
Step 4: Measure conversion
Conversions are created via the track! method. For example:
class SignupController < ApplicationController
def signup
@account = Account.new(params[:account])
if @account.save
track! :signups
redirect_to @acccount
else
render action: :offer
end
end
end
The tracking of the metrics seems to work, while the 'conversion' field on vanity dashboard remains fixed at 0
no clue how to fix.
Thanks in advance
I want to define a method that takes keyword arguments. I would like it to raise when keyword arguments are not provided, and I can code this myself - but ideally I would like to let Ruby do that for me. Also I would like to be able to inspect the freshly defined method using Method#parameters. If I use a shorthand double-splat (like **kwargs) the actual structure I expect is not visible to parameters.
I can of course do this:
define_method(:foo) do | foo:, bar: |
# ...
end
which achieves the desired result:
method(:foo).parameters
# => [[:keyreq, :foo], [:keyreq, :bar]]
but I cannot pass those arguments programmatically, they have to be literally placed in the code. Is there a way I could bypass this?
I am using JIRA api to extract timespent by users on issues. The time spent is in the format: "12w 1d 2h 5m" or "12h" or "12m" etc The API isn't exporting the number of hours. Is there a quick (requires no effort on my part) way to convert this to hours (or seconds). I suppose this is some sort of a standard format, is there a name for it? I know how to do this myself, just don't want to reinvent the wheel
I have read the data online but it is in a string format. I've also researched online but the few examples I checked returned string format too. How can i make it so that it returns a JSON object.
assuming the result of reading the data was
text = '{"one":1,"two":2}'
then i used:
data = JSON.parse(text).to_json
but when i do
puts data.class
the result is still a string
I'm adding the carrierwave gem to an app in Rails, and I'm getting a weird NameError. I've followed all other posts on it, yet none of them worked. Here's the error:
uninitialized constant Post::ImageUploader
Extracted source (around line #2):
class Post < ActiveRecord::Base
mount_uploader :image, ImageUploader
end
And post.rb:
class Post < ActiveRecord::Base
mount_uploader :image, ImageUploader
end
Also, here's one site that I went to, but it didn't describe where to place the code, so I got really confused.
Can anyone help me figure out what's going on? Thanks.
I'm trying to build a simple websocket notification system using rails observers gem and faye. The problem is that I can't publish with faye from the observer.
First I created the observer:
class ScoreObserver < ActiveRecord::Observer
def after_save(score)
@notification = Notification.new(user_id: '2', content: '¡rororscoreeeeeeeeeeeeee!')
if @notification.save
client = Faye::Client.new('http://localhost:3000/faye')
client.publish("/messages/new", {
'title' => 'testitle',
'content' => 'testcontent'
})
end
end
end
As you can see it 'observes' the scores model and insert a record in the notifications table. After that I want it to push a notification with faye using pubilsh.
Then in the client side I run the subscribe script
$(function() {
var faye = new Faye.Client('http://localhost:9292/faye');
faye.subscribe("/messages/new", function(data) {
eval(data);
alert('it works')
});
});
And it doesn't work. The observer is aware of the action and makes the record save correctly but the client doesn't receive any push from the websocket.
I've tested the subscription with a simple broadcast and it works so it seems that is the observer part which is failling. Websockets are up and listening
Do you have any clue of what could be wrong ?
I was looking for an alternative just in case this approach is wrong, and I thought about render a script from the observer and broadcast/publish from a .js file, since all the tuts do it from a script. But I'm having some trouble with this approach too, I can't render a script from the observer in respond_to since the model extends from Observer and not from Base and doesn't have the method.
Thanks
I have problem with displaying files. My app:
class User
has_many :downloads
has_many :downloaded_files, :through => :downloads, source: :file
end
class File
attr_accessor :downloaded
has_many :downloads
has_many :users, :through => :downloads
end
class Download
belongs_to :user
belongs_to :file
end
And when user log in i want to display all files but downloaded files by current user should be the last. The file table is about 500 records so i need simple and fast method. Have someone any idea ?
Rails 4.2.1 Ruby 2.2.2 Postgresql
My app uploads an image to S3 and returns the URL of that image. However, it returns a URL like http://ift.tt/1IVHbHu
How can I get it to return the simple URL that doesn't require access key and signature in the URL? Also, the links expire pretty quickly.
Here is my code:
bucket.objects[filename].write(result.to_blob, {:acl=>:public_read})
url = bucket.objects[filename].url_for(:read, :secure => false).to_s
I'm trying to access our database with some fairly simple CGI/Ruby and DBI:
#!/usr/bin/ruby -w
require "dbi"
dbh = DBI.connect("dbi:Mysql:my:mydb", "XXXX", "XXXX")
...
query = "select ETA from mydb.mytable where ID = #{someval}"
rows = dbh.execute(query)
while row = rows.fetch() do
# Do some stuff
...
end
That works fine most of the time, but I hit a record which broke it with the error:
/usr/lib/ruby/vendor_ruby/dbd/Mysql.rb:120:in `parse': invalid date (ArgumentError)
from /usr/lib/ruby/vendor_ruby/dbd/Mysql.rb:120:in `parse'
from /usr/lib/ruby/vendor_ruby/dbi/row.rb:66:in `block in convert_types'

from /usr/lib/cgi-bin/test:36:in `each'
from /usr/lib/cgi-bin/test:36:in `<main>'
After a bit of detective work I found that it had a date of 0000-00-00 which fetch() doesn't like. Undefined dates are OK, and DBI in Perl can handle all zero dates, it's just DBI in Ruby.
I can fix the database, and I'll try to get the app which wrote the value to the database fixed too, but I think that my Ruby should be resilient to such things. Is there a way to work around this, maybe using rescue somehow?

:revenue => Money.new(record.revenue_centimes , record.revenue_currency).format,
:fees => Money.new(record.fee_centimes,record.fee_currency).format,
:created => record.created_count ,
:paid => record.paid_count ,
:partially_paid => record.partially_paid_count }
month_array.push(m)
}
respond_with(month_array, status: :ok, template: 'api/merchant/mobiles/history')
end
My question is how do i write the rabl template 'api/merchant/mobiles/history' to get the above json response ?
Note : I am using rails money gem. Thats why there is Money.new etc
Here is my current deck.rb file:
require 'squib'
require 'game_icons'
Squib::Deck.new(cards: 4, layout: %w(hand.yml layout.yml), width: 825, height: 1425) do
background color: '#FFFFFF'
rect x: 0, y: 0, width: 825, height: 1425, x_radius: 38, y_radius: 38
data = csv file: 'country.csv'
png file: data['Art'], layout: 'Art'
png file: 'textbox.png', x: 50, y: 890
png file: 'titlebox.png', x: 65, y: 30
text(str: data['Ability'], x: 100, y: 900) do |embed|
embed.svg key: ':tribute:', file: 'tributesmall.svg'
end
%w(Title Ability Quote Type Subtype).each do |key|
text str: data[key], layout: key, markup: true
end
%w(Tribute Power Dominion).each do |key|
svg file: "#{key.downcase}.svg", layout: "#{key}Icon"
text str: data[key], layout: key
end
save_png prefix: 'country_'
end
This puts the Ability column of my .csv onto every single card. However, it doesn't replace any text with icons. If I switch the relevant block to this:
text(str: 'Gain 1 :tribute:', x: 100, y: 900) do |embed|
embed.svg key: ':tribute:', file: 'tributesmall.svg'
end
This now puts "Gain 1 [my tribute icon]" onto every single card.
Here's exactly what I want to do: Whenever one of my cards has within the Ability column of my .csv the text "Gains 1 tribute", the output is "Gains 1 [my tribute icon]" within the text box of the card, formatted so that it's part of the regular Ability text. Is this possible?
Thanks!
I am trying to write a function that compares whether one number x1 to the power of another number x2 is greater than another number y1 to another number y2 power.
For example, suppose we have a pair of numbers for x.
x = [2,10]
and another pair y
y = [3,9]
In this case y1 ** y2 is greater than x1 ** x2.
However, sometimes there are really large, scary numbers. Like so
x = [935243113, 987702643]
y = [50894069, 704259526]
To calculate this, I tried using the mod 10 algorithm
(x[0] ** x[1]) % 10 > (y[0] ** y[1]) % 10
However, apparently this algorithm doesn't work. Is there a more efficient algorithm for this.
