h1. !http://railsapps.github.io/images/rails-36x36.jpg(Rails Application for Devise with RSpec and Cucumber)! Rails 3.2

This repo contains a Rails 3.2 example application integrating "Devise":http://github.com/plataformatec/devise with "RSpec":http://rspec.info/ and "Cucumber":http://cukes.info/.

"Devise":http://github.com/plataformatec/devise gives you ready-made authentication and user management.
"RSpec":http://rspec.info/ is a popular alternative to the Test::Unit testing framework.

You really should use the "rails-devise":https://github.com/RailsApps/rails-devise newer version.

h2. What Is Implemented -- and What Is Not

This is a demonstration application that allows you to visit a home page and see a list of users. With the default user's email and password (supplied below), you can log in and view details for each user. Devise provides user management so a visitor can register with an email address and password and create an account. Devise provides authentication so access to the site can be limited to users who are registered and logged in.

h2. Dependencies

Before generating your application, you will need:

The Ruby language (version 1.9.3 or 2.0.0)
The Rails gem (version 3.2.14)

See the article "Installing Rails":http://railsapps.github.io/installing-rails.html for advice about updating Rails and your development environment.

h2. Getting the Application

You have several options for getting the code.

h3. Fork

If you'd like to add features (or bug fixes) to improve the example application, you can fork the GitHub repo and "make pull requests":http://help.github.com/send-pull-requests/. Your code contributions are welcome!

h3. Clone

If you want to copy and customize the app with changes that are only useful for your own project, you can clone the GitHub repo. You'll need to search-and-replace the project name throughout the application. You probably should generate the app instead (see below). To clone:

$ git clone git://github.com/RailsApps/rails3-devise-rspec-cucumber.git

You'll need "git":http://git-scm.com/ on your machine. See "Rails and Git":http://railsapps.github.io/rails-git.html.

h3. Generate

If you want to use the project as a starter app, use the "Rails Composer":http://railsapps.github.io/rails-composer/ tool to generate a new version of the example app. You'll be able to give it your own project name when you generate the app. Generating the application gives you many additional options.

To build the example application, run the command:

$ rails new rails3-devise-rspec-cucumber -m https://raw.github.com/RailsApps/rails-composer/master/composer-Rails3_2.rb -T

Use the @-T@ flag to skip Test::Unit files.

The @$@ character indicates a shell prompt; don't include it when you run the command.

This creates a new Rails app named @rails3-devise-rspec-cucumber@ on your computer. You can use a different name if you wish.

You'll see a prompt:

question  Install an example application?
      1)  I want to build my own application
      2)  membership/subscription/saas
      3)  rails-prelaunch-signup
      4)  rails3-bootstrap-devise-cancan
      5)  rails3-devise-rspec-cucumber
      6)  rails3-mongoid-devise
      7)  rails3-mongoid-omniauth
      8)  rails3-subdomains

Choose rails3-devise-rspec-cucumber. The Rails Composer tool may give you other options (other choices may have been added since these notes were written).

The application generator template will ask you for additional preferences:

 question  Web server for development?
       1)  WEBrick (default)
       2)  Thin
       3)  Unicorn
       4)  Puma
 question  Web server for production?
       1)  Same as development
       2)  Thin
       3)  Unicorn
       4)  Puma
 question  Template engine?
       1)  ERB
       2)  Haml
       3)  Slim
   extras  Set a robots.txt file to ban spiders? (y/n)
   extras  Use or create a project-specific rvm gemset? (y/n)
   extras  Create a GitHub repository? (y/n)

h4. Web Servers

Use the default WEBrick server for convenience. If you plan to deploy to Heroku, select "thin" as your production webserver.

h4. Template Engine

The example application uses the default "ERB" Rails template engine. Optionally, you can use another template engine, such as Haml or Slim. See instructions for "Haml and Rails":http://railsapps.github.io/rails-haml.html.

h4. Other Choices

Set a robots.txt file to ban spiders if you want to keep your new site out of Google search results.

It is a good idea to use "rvm":https://rvm.io/, the Ruby Version Manager, and create a project-specific rvm gemset (not available on Windows). See "Installing Rails":http://railsapps.github.io/installing-rails.html.

If you choose to create a GitHub repository, the generator will prompt you for a GitHub username and password.

h4. Troubleshooting

If you get an error "OpenSSL certificate verify failed" or "Gem::RemoteFetcher::FetchError: SSL_connect" see the article "OpenSSL errors and Rails":http://railsapps.github.io/openssl-certificate-verify-failed.html.

If you get an error like this:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
    composer  Running 'after bundler' callbacks.
The template [...] could not be loaded.
Error: You have already activated ..., but your Gemfile requires ....
Using bundle exec may solve this.

It's due to conflicting gem versions. See the article "Rails Error: “You have already activated (…)”":http://railsapps.github.io/rails-error-you-have-already-activated.html.

Other problems? Check the "issues":https://github.com/RailsApps/rails3-devise-rspec-cucumber/issues.

h3. Edit the README

If you're storing the app in a GitHub repository, please edit the README files to add a description of the app and your contact info. If you don't change the README, people will think I am the author of your version of the application.

h2. Getting Started

h3. Install the Required Gems

Check the Gemfile to see which gems are used by this application.

If you used the "Rails Composer":http://railsapps.github.io/rails-composer/ tool to generate the example app, the application template script has already run the @bundle install@ command.

If not, you should run the @bundle install@ command to install the required gems on your computer:

$ bundle install

You can check which gems are installed on your computer with:

$ gem list

Keep in mind that you have installed these gems locally. When you deploy the app to another server, the same gems (and versions) must be available.

I recommend using "rvm":https://rvm.io/, the Ruby Version Manager, to create a project-specific gemset for the application. See the article "Installing Rails":http://railsapps.github.io/installing-rails.html.

h3. Configure Email

This example application doesn't send email messages. However, if you want your application to send email messages (for example, if you plan to install the Devise @:confirmable@ module) you must configure the application for your email account. See the article "Send Email with Rails":http://railsapps.github.io/rails-send-email.html.

h3. Configure Devise

You can modify the configuration file for Devise if you want to use something other than the defaults:

config/initializers/devise.rb

h3. Configuration File

The application uses the "figaro gem":https://github.com/laserlemon/figaro to set environment variables. Credentials for your administrator account and email account are set in the config/application.yml file. The .gitignore file prevents the config/application.yml file from being saved in the git repository so your credentials are kept private. See the article "Rails Environment Variables":http://railsapps.github.io/rails-environment-variables.html for more information.

Modify the file config/application.yml:

# Add account credentials and API keys here.
# See http://railsapps.github.io/rails-environment-variables.html
# This file should be listed in .gitignore to keep your settings secret!
# Each entry sets a local environment variable and overrides ENV variables in the Unix shell.
# For example, setting:
# GMAIL_USERNAME: Your_Gmail_Username
# makes 'Your_Gmail_Username' available as ENV["GMAIL_USERNAME"]
# Add application configuration variables here, as shown below.
#
GMAIL_USERNAME: Your_Username
GMAIL_PASSWORD: Your_Password
ADMIN_NAME: First User
ADMIN_EMAIL: user@example.com
ADMIN_PASSWORD: changeme

If you are planning to customize the application to send email using a Gmail account, you can add the user name and password needed for the application to send email. See the article "Send Email with Rails":http://railsapps.github.io/rails-send-email.html.

If you wish, set your name, email address, and password for the first user's account. If you prefer, you can use the default to sign in to the application and edit the account after deployment. It is always a good idea to change the password after the application is deployed.

All configuration values in the config/application.yml file are available anywhere in the application as environment variables. For example, @ENV["GMAIL_USERNAME"]@ will return the string "Your_Username".

If you prefer, you can delete the config/application.yml file and set each value as an environment variable in the Unix shell.

h3. Set Up a Database Seed File

The db/seeds.rb file initializes the database with default values. To keep some data private, and consolidate configuration settings in a single location, we use the config/application.yml file to set environment variables and then use the environment variables in the db/seeds.rb file.

puts 'DEFAULT USERS'
user = User.find_or_create_by_email :name => ENV['ADMIN_NAME'].dup, :email => ENV['ADMIN_EMAIL'].dup, :password => ENV['ADMIN_PASSWORD'].dup, :password_confirmation => ENV['ADMIN_PASSWORD'].dup
puts 'user: ' << user.name

You can change the first user's name, email, and password in this file but it is better to make the changes in the config/application.yml file to keep the credentials private. If you decide to include your private password in the db/seeds.rb file, be sure to add the filename to your .gitignore file so that your password doesn't become available in your public GitHub repository.

Note that it's not necessary to personalize the db/seeds.rb file before you deploy your app. You can deploy the app with an example user and then use the application's "Edit Account" feature to change name, email address, and password after you log in. Use this feature to log in as the first user and change the user name and password to your own.

You may wish to include additional sample users:

user2 = User.find_or_create_by_email :name => 'Second User', :email => 'user2@example.com', :password => 'changeme', :password_confirmation => 'changeme'
puts 'user: ' << user2.name

This will add a second user to the database.

h3. Set the Database

Prepare the database and add the default user to the database by running the commands:

$ rake db:migrate
$ rake db:seed

Use @rake db:reset@ if you want to empty and reseed the database.

Set the database for running tests:

$ rake db:test:prepare

If you’re not using "rvm":https://rvm.io/, the Ruby Version Manager, you should preface each rake command with @bundle exec@. You don’t need to use @bundle exec@ if you are using rvm version 1.11.0 or newer.

h3. Change your Application's Secret Token

If you've used the Rails Composer tool to generate the application, the application's secret token will be unique, just as with any Rails application generated with the @rails new@ command.

However, if you've cloned the application directly from GitHub, it is crucial that you change the application's secret token before deploying your application in production mode. Otherwise, people could change their session information, and potentially access your site without your permission. Your secret token should be at least 30 characters long and completely random.

Get a unique secret token:

rake secret

Edit your config/initializers/secret_token.rb file to add the secret token:

Rails3DeviseRspecCucumber::Application.config.secret_token = '...some really long, random string...'

h2. Test the App

You can check that your app runs properly by entering the command

@$ rails server@

To see your application in action, open a browser window and navigate to "http://localhost:3000/":http://localhost:3000. You should see the default user listed on the home page. When you click on the user's name, you should be required to log in before seeing the user's detail page.

To sign in as the default user, (unless you've changed it) use

email: user@example.com
password: changeme

You should delete or change the pre-configured logins before you deploy your application.

If you test the app by starting the web server and then leave the server running while you install new gems, you’ll have to restart the server to see any changes. The same is true for changes to configuration files in the config folder. This can be confusing to new Rails developers because you can change files in the app folders without restarting the server. Stop the server each time after testing and you will avoid this issue.

h2. Deploy to Heroku

For your convenience, here is a "Tutorial for Rails on Heroku":http://railsapps.github.io/rails-heroku-tutorial.html. Heroku provides low cost, easily configured Rails application hosting.

h2. Customizing

"Devise":http://github.com/plataformatec/devise provides a variety of features for implementing authentication. See the Devise documentation for options.

This application provides no useful functionality apart from demonstrating Devise with RSpec and Cucumber working together on Rails 3. Add any models, controllers, and views that you need.

h2. Testing

The example application contains a suite of RSpec unit tests and Cucumber scenarios and step definitions.

After installing the application, run @rake -T@ to check that rake tasks for RSpec and Cucumber are available.

Run @rake spec@ to run all RSpec tests.

Run @rake cucumber@ (or more simply, @cucumber@) to run all Cucumber scenarios.

Please send the author a message, create an issue, or submit a pull request if you can contribute improved RSpec or Cucumber files.
