I'm running on windows 7 and I cannot install/create the rspec files and capybara which is needed to work on the assignment .
If you could finish the simple setup steps listed below and give me a link to the empty app repository so I could download to finish the assignment , I will be so gratefull to you .
by the way , I 'm getting the following errors in step 4 if someone could help . I have asked before but no one have answered ;(
Steps needed :
Create a new Rails application called todolists
Add the following specification to your Gemfile
group :test do
gem 'rspec-rails', '~> 3.0'
gem 'capybara'
end
Run the bundle command to resolve new gems
From the todolists application root directory, initialize the rspec tests using the rails generate
rspec:install command
[todolists]$ rails generate rspec:install
create .rspec
create spec
create spec/spec_helper.rb
create spec/rails_helper.rb
Add the following line to .rspec to add verbose output to test results.
--format documentation
Download and extract the starter set of bootstrap files.
1
|-- Gemfile
|-- db
| ‘-- seed.rb
‘-- spec
‘-- features
‘-- module3_action_pack_spec.rb
• overwrite your existing Gemfile with the Gemfile from the bootstrap fileset. They should be nearly identical,
but this is done to make sure the gems and versions you use in your solution can be processed by the
automated Grader when you submit. Any submission should be tested with this version of the file.
• overwrite your existing db/seed.rb file using the seeds.rb provided with the bootstrap fileset. The
bootstrap seeds.rb file contains some test data that will be useful during development and unit tests.
• add the spec/features/module3_action_pack_spec.rb file provided with the bootstrap fileset to your
todolists application. Within your application root directory, you will first need to create a corresponding
spec/features sub-directory to place the module3_action_pack_spec.rb file. This file contains tests that
will help determine whether you have completed the assignment.
6-run rspec
The problem is that rspec versions > 2.8.0 don't go well with Windows. Can you try to install an older version of rspec-rails? Include this in your Gemfile.
gem 'rspec-rails', '~> 2.8'
Run bundle install and then try
rails g rspec:install

bundle gem gem_name --test=minitest
allows for choosing minitest, but how to make bundler generate code for minitest/spec instead of minitest/test.
This seems to work now:
bundle gem myapp --test minitest
It is not currently possible.
-t, --test=minitest, --test=rspec
Specify the test framework that Bundler should use when generating
the project. Acceptable values are minitest and rspec. The
GEM_NAME.gemspec will be configured and a skeleton test/spec
directory will be created based on this option. If this option is
unspecified, an interactive prompt will be displayed and the answer
will be saved in Bundler's global config for future bundle gem use.
However the bundle gem generator generates less than 10 lines of tests, so converting to MiniTest::Spec is hardly a herculean task.
I am reading ruby and rails tutorial 2nd edition book.
I am facing problem to do dynamic title in title pages.
In this book write done this path "spec/requests/static_pages_spec.rb" and i have not found any spec folder in rails project where it is located ? where can create a static_pages_spec.rb file ?
I am using rails 4.0.2
book link :http://ruby.railstutorial.org/chapters/rails-flavored-ruby#top
Listing 4.4. Updated tests for the Home page’s title.
spec/requests/static_pages_spec.rb
please help me
path "spec/requests/static_pages_spec.rb "
May i create it spec folder in rails root folder ?
Folder spec located in rails root dir.
in Rails you can use Rspec generator or create helper:
add to Gemfile:
gem 'rspec-rails'
run rails generator:
rails g rspec:install
This create folder spec in you project and generate spec_helper.rb
And run rspec or bundle exec rspec.
Folder spec located in rails root directory in your rails app.
in Rails you can use Rspec generator:
following Gem add to Gemfile:
gem 'rspec-rails'
and then run following command on terminal
rails g rspec:install
This create folder spec in you project and generate spec_helper.rb
And run rspec or bundle exec rspec
This two commands seem to generate practically the same thing
rails plugin new __name__
bundle gem __name__
There is a hidden detail I haven't notice?
which one do you use, and basically, why?
Thanks
They can all generate a barebone gem but they are different.
rails plugin new could generate a dummy app inside test, and a basic test_helper, which would be very handy if you want to add some functional/integration tests in gem. You can also revise that a bit to use Rspec. bundle gem would not do that.
If you develop the gem for Rails and need such tests, rails plugin would be better. Otherwise bundle or a gem generating gem jeweller.
Plugins are more or less deprecated in favor of gems in recent versions of Rails.
As far as I can tell, running rails plugin my_gem simply creates a 'my_gem' directory in the root of your rails app.
It's not too much different from running bundle gem my_gem except that it stubs out a couple of test files, and runs bundle install.
This may be useful if you're creating a gem that's made to be run on rails - where you need a "rails environment" (see the test/dummy/app directory).
Still, if you do it this way, it appears the gem is added right into the root of your rails project. You could always move it, but if you were to run bundle gem you could do so wherever you want.
In Rails -
Where should I locate Gems? I downloaded bootstrap and it's working, as well as a sample Rails app, separately, but I want them to work together. There is a bootstrapped rails gem (http://rubygems.org/gems/bootstrapped-rails) which I downloaded, but I'm unsure as to where I should locate it. Under models?
And how do I make sure I am referring to it? I need to add something in controller as well?
Again, more an answer to the question in the title than to what was intended by the questioner but you can use
bundle show <gemname>
To locate the directory where a gem is installed.
As Dfr mentioned: https://github.com/seyhunak/twitter-bootstrap-rails
Twitter bootstrap isn't anything more than (mostly) a collection of css/js/image files.
Add this to your gemfile
gem "twitter-bootstrap-rails"
run
bundle install
run for simple css
rails generate bootstrap:install static
It should place relevant js and css files into your application.js and application.css files accordingly. (Read more about asset pipeline)
To get you started, in the gem's link under section - "Generating layouts and views", you can see rake tasks to generate sample layouts.
e.g.
rails g bootstrap:layout application fixed
You should now have a twitter-bootstraped application.html.erb file under views/layouts.
To answer the question in the title, you can locate your gems by running gem env in the console. That will give you the specific information about your "RubyGems Environment:" When you run gem install some_gem_name it will add this gem to your system.
However, what it sounds like your trying to do is add a gem to your app. If this is the case you add gems to a rails application's Gemfile.
So using your example, you'd locate your Gemfile and add the following:
gem "bootstrapped-rails", "~> 2.0.8.5"
Once that's done, you run bundle install in your terminal.
I find that a good resource for basic rails information can be found here: http://guides.rubyonrails.org/getting_started.html
The tutorial is short and it will give you a great starting point.
I'm not sure if this sort of thing is very common, but I keep finding myself trying to create gems that are just wrappers around a Rails application.
My gem will have a generator to create a config.ru but the Rails application will live inside the gem's lib directory. I need to know how to "embed" a Rails application and configure it so that it can be run inside the gem.
For example:
$ mygem new project
mygem created a directory called "project" with the following files:
project/config.ru
project/widgets/
project/foobars/
My gem will also generate some directories that will need to be added to Rails somehow so that I can access the code in those directories from the Rails app living inside the Gem.
Any help or advice you can give me would be appreciated.
To clarify, I'm not trying to create a Rails engine, or plugin to a Rails application. I'm trying to create a fully-fledged Rails application, but package it as a gem so that a user of my gem can run the gem (the rails app) without needing to know that it's using Rails behind the scenes.
Update: Okay, I've got a little bit working now. I've created the gem and generated the rails project inside the gem's lib directory.
$ bundle gem my_gem && cd my_gem/lib
$ rails new my_gem --skip-bundle
Which leaves me with:
my_gem/
my_gem.gemspec
bin/my_gem
lib/
my_gem.rb
my_gem/
version.rb # generated by bundler
# the rails app:
app/
config/
Gemfile
...etc
Since this gem requires Rails, I started adding the gems defined in the Rails Gemfile as dependencies in the gem's Gemspec, but I'm a little confused as to how to handle the assets group in the Gemfile.
# Rails Gemfile
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
# gemspec
Gem::Specification.new do |gem|
gem.name = "my_gem"
# ...
gem.add_dependency 'rails', '3.2.8'
gem.add_dependency 'sqlite3'
gem.add_dependency 'jquery-rails'
# how to add the assets group gems?
end
Try this and see if it helps you make progress.
Gems are just directories of files, and you can put whatever files you want into a gem.
Create:
Create a blank gem full-blown Rails project:
$ bundle gem my_gem
Then a Rails app:
$ rails new my_app --skip-bundle
Copy the Rails files into the gem:
$ cp -R my_app/* my_gem
Bundle everything into your Rails app:
$ cd my_gem
$ bundle install --binstubs --path vendor/bundle
$ cd -
Make the Rakefile have the gem tasks and the Rails setup:
#!/usr/bin/env rake
require "bundler/gem_tasks"
require File.expand_path('../config/application', __FILE__)
MyApp::Application.load_tasks
Verify that it starts:
$ rails server
Load Path:
To control where Rails looks for files, such as "external" configuration files, you can use the file config/application.rb with any directory paths like this:
# Add additional load paths for your own custom dirs
# config.load_paths += %W( #{config.root}/../customdir )
Note the ".." which means go above the Rails directory. This gives you a path relative to the gem.
If you prefer you can specify an absolute path, for example if you know the user will always keep his external files in "~/myfiles/". You can also choose to use ENV vars to send in whatever directory you want.
If you read about load path capabilties, look for lines that are shorthand for adding a directory to the front of the load path because you may want to put your external diretories first:
$:.unshift File.dirname(__FILE__)
Gem Build:
Edit my_gem.gemspec to add your own description, homepage, summary, etc. then build:
$ gem build my_gem.gemspec
Successfully built RubyGem
Name: my_gem
Version: 0.0.1
File: my_gem-0.0.1.gem
Now your Rails app is packaged as a gem.
The config.ru should be a typical Rails one. No special changes AFAIK.
When your user wants to install your app:
$ gem install my_gem
The gem will install in the user's typical gem directory. If you want to adjust this, see this page on rubygems: http://docs.rubygems.org/read/chapter/3
Crate:
You may also want to investigate the Crate project:
Crate: Packaging Standalone Ruby Applications
http://www.slideshare.net/copiousfreetime/crate-packaging-standalone-ruby-applications
Rack:
To use config.ru here is the typical Rails setup:
# Rails.root/config.ru
require "config/environment"
use Rails::Rack::LogTailer
use ActionDispatch::Static
run ActionController::Dispatcher.new
For your project, you want to require some files before Rails. You'll want to learn about the Ruby "require" and how it finds files using LOAD_PATH.
The easy way:
# Rails.root/config.ru
require_relative 'filename'
require "config/environment"
Or to put the user's custom directory up couple directory levels:
require './../../filename' # not the best for security
Or to use an absolute path, read about File.expand_path:
File.expand_path(__FILE__)
Or to use the current directory and put it on the load path:
$LOAD_PATH.unshift(File.dirname(__FILE__))
require 'filename'
Lots of choices for you to consider. Hope this helps!
What about the question, "How am I going to run the Rails application inside the gem?".
A Rails application has controllers and views to run a web server. What you need are actions to create, list, update, and destroy. Exposing these actions without a web server is essentially having such methods in a class. That's a normal standard type of gem in the first place.
So maybe your questions is really, how do I write a gem where I have ActiveRecord, and the other Rails stuff.
First, you need to make your gem dependent on the Rails gems you need. You do this in the gemspec file for your gem.
Then it really is just a matter of your gem code doing a require of the right Rails gems you need.
I'm not sure if this will help, as I read through everything and I couldn't find the motivation behind why you were doing this. One of the reasons I came up with was making something that can be used on a desktop environment. In that case you could try using something like Bowline. If you just want to provide an application that others can download and use and install themselves, then you can probably assume they can follow at least basic developer kind of instructions and you could just provide the whole app on github or as a zip file. See an example of someone else doing something similar over on Fat Free CRM's github page.
