I'm likely doing something very simply wrong, but I'm not quite sure what it is. I am porting a rails 2 application to rails 3. This application uses webmock for a bunch of it's tests.
If I include
gem 'webmock'
In my Gemfile, the tests pass, but when I start the server and run the app locally, hitting a controller that should make a web call throws an error:
WebMock::NetConnectNotAllowedError
If I do NOT include the line in my Gemfile, then when I run the app locally, it works fine, but the tests error out with:
`require': no such file to load -- webmock (LoadError)
When this line is hit in my test_helper.rb
require 'webmock'
I'm guessing I've got something configured wrong, but I haven't hit the right google incantation to shed any light on it yet. Where I did I go astray?
Thank you.
Try telling your Gemfile to only load webmock when you're in a test environment:
group :test do
gem "webmock"
end
On my Ruby 1.9 Rails 3 instance I have something like the following:
group :test do
gem "mocha"
gem "webmock"
end
group :development do
gem 'ruby-debug19', :require => 'ruby-debug'
end

I'm following this railscast on performance testing, but I'm immediately running into an issue.
My app is rails 3.2.11, so according to the railscast it should include performance testing, but I don't have a folder called 'test' at all. When I run 'rails generate performance_test homepage' nothing happens or is generated. So I created one manually (to exactly match the railscast source code), but when I run rake test:benchmark I get the error
Don't know how to build task 'test:benchmark'
If I add the 'rails-perftest' gem to my gemfile and run bundle, then again try to generate a performance_test nothing happens, and when I then run rake test:benchmark, it throws a different error of
uninitialized constant Rails::SubTestTask
I've been sure to include the following dependencies in my gem file:
gem 'ruby-prof', group: :test
gem 'test-unit', group: :test
Could anyone help advise me what I'm doing wrong? Thanks!
I am not 100% certain on this, but I am guessing that you might not have your application.rb file configured accordingly. Also check your Gemfile.lock file and run the command bundle install because it could also be something funky going on with your Gems and dependencies.
I am trying to use the gem gchartrb to create some graphs/charts in my RoR application.
I have looked into several tutorial and all say the same thing, that I have to add
require 'google_chart'
But I am getting the message:
no such file to load -- google_chart
I have the require inside my controller, I have confirmed that the gem is installed.
I am using Rails 3.
Also, I have tried adding config.gem 'gchartrb', :lib => 'google_chart' in my environment.rb as suggested here but nothing changed
Thanks for your help
EDIT:
I have also tried with the gem googlecharts, what I have in my Gemfile is:
gem "googlecharts", :require => "gchart"
but I get no such file to load -- gchart when I try to load the view.
I am not sure, it is required now or not. But it worked for me in Rails 3 as well. I am using Rails 3.0.10. I added below 2 lines and it worked for me.
1) gem 'gchartrb' in Gemfile
2) require 'google_chart' in config/boot.rb
Hope it helps!
config.gem is for rails 2.3.X.
For rails 3, you will need to add the gem to your Gemfile and run gem bundle
You may also need to check that the google_charts gem actually supports Rails 3...
Given that the latest code update seems to have been in 2008 - that might not actually be likely. :(
You can try it anyway and see...
I have a Rails 3 app that I am turning into a Rails engine / gem.
This engine has some gem dependencies that I have put inside it's .gemspec file.
I have created a new 'parent' Rails 3 app, and I would like to add my engine gem to the Gemfile and have the gem's dependencies automatically 'loaded', but this does not work for me! bundle install installs the gem dependencies fine, but when I start the server, the app crashes because they are not loaded.
For example, my engine's gemspec contains these lines:
s.add_runtime_dependency(%q<rails>, ["= 3.0.7"])
s.add_runtime_dependency(%q<acts_as_commentable>, [">= 3.0.1"])
s.add_runtime_dependency(%q<haml>, [">= 3.1.1"])
.. and the parent Rails 3 application has these lines in its Gemfile:
source 'http://rubygems.org'
gem 'my_engine', :path => "~/src/gems/my_engine"
But I get the following error:
undefined local variable or method `acts_as_commentable'
from /home/user/src/gems/my_engine/app/models/account.rb:66:in `<class:Account>'
But if I add gem 'acts_as_commentable', '>= 3.0.1' to the Gemfile of the parent Rails 3 app, then the gem is loaded and the error disappears.
I am using Rails 3.0.8.
Does anyone have any suggestions? Do I need to change something about the way my engine is loading?
During main Rails app boot, Bundler will only require dependencies directly listed in the Gemfile but not any sub-dependencies. It's your library's/Engine's responsibility to require its dependencies when it itself gets required. You can do so using initializers in your Railtie.
class MyRailtie < Rails::Railtie
initializer "require stuff" do
require "stuff"
end
end
In our Rails Engine we used a small trick to require dependencies automatically. Unfortunately you can't specify whether or not they should load in the .gemspec, which would allow for greater control.
Gem.loaded_specs["our_rails_engine"].dependencies.each do |d|
begin
require d.name
rescue LoadError => le
# Put exceptions here.
raise le if d.name !~ /factory_girl_rails/
end
end
I'm looking at Spree (the superhero of Rails Engines!), and they do this in spree_core-0.60.1/lib/spree_core.rb:
require "rails/all"
require 'state_machine'
require 'paperclip'
require 'stringex'
require 'will_paginate'
require 'nested_set'
require 'acts_as_list'
require 'resource_controller'
require 'active_merchant'
require "meta_search"
require "find_by_param"
So the answer is that within your gem, you have to require all of it's gem dependencies one by one. Well, that's how I will do it for now. But please comment if this ever changes in the future.
Seems it don't work, i create a host project and a sub-project with rails 3 engine.
Added the gem to engine's gemspec
s.add_dependency 'simple_form'
then added the require to engine_name.rb like below
require 'simple_form'
But if delete the line [gem 'simple_form'] in host project's Gemfile, it will show undefined immediatly

My Gemfile:
group :test do
gem "rspec-rails"
gem 'webrat', '0.7.1'
gem 'spork', '0.9.0.rc4'
gem 'factory_girl_rails'
end
Even tough it seems I have everything as it should, I keep getting that error. I also have factories.rb created.
Thanks
I suppose you try in console in development environment. But you add the Factory gem only in test environment.
If you want access to Factory_girl in development use in your Gemfile :
group :test, :development do
gem 'factory_girl_rails'
end
Or if you want test your Factory launch your console in test environment :
rails c test
We had a similar problem on our end, rake spec seemed to be randomly failing with the error uninitialized constant FactoryGirl. The error was random -> coming and going. We went back half a dozen git commits to try and resolve it. In the end it was a silly mistake.
The fundamental problem is RAILS_ENV is set to development. It needs to be set to test when you run rake spec.
Address by:
Making certain that we are running rake spec in the RAILS_ENV test environment and its exported/sourced properly. To never confuse our environemnts, we modified zsh $RPROMPT env variable to show the current env.
export RPROMPT="[%{$fg_no_bold[yellow]%}$RAILS_ENV%{$reset_color%}]"
Require FactoryGirl in the spec ruby files gave a much better error message. At least rspec would run vs just fail outright this way when the environment was wrong. We also updated our gemfile to make sure factory_girl_rails and factory_girl were loaded both for development and testing.
Now we just run rpsec using the gem guard in a dedicated terminal with the proper RAILS_ENV set.
Its one of those gotchas.
We're running Ruby 1.9.3, Rails 3.2.9, Rspec 2.12, factory_girl 4.1.
I also ran into this while I was doing the Hartl tutorial.
If you are using "Spork" to speed up your tests and it is running in the background when you add the FactoryGirl code, you will need to stop it and restart it.
You should also change Factory.define to FactoryGirl.define, like in this example
FactoryGirl.define do
factory :user do
name 'John Doe'
date_of_birth { 21.years.ago }
end
end
from the factory_girl documentation
I am trying to use the Sunlight API gem with a Rails project. I have installed the gem and can successfully use it from irb.
However, when I put the require statement (require 'sunlight') in sunlight.rb in config/initializers, I get the following error:
/opt/local/lib/ruby/gems/1.8/gems/activesupport-3.0.0.beta3/lib/active_support/dependencies.rb:209:in `require': no such file to load -- sunlight (LoadError)
I checked the permissions on the gems directory, and it is world readable/executable.
Here is the code from sunlight.rb:
require 'rubygems'
require 'sunlight'
Sunlight::Base.api_key = 'bb7b775755054c54aa9715d202f6785c'
Can anyone tell me how to fix this? TIA!
Is sunlight listed in your Gemfile? Rails3 uses Bundler to manage Gem installations.
