Clearance

Rails authentication with email & password.

We have clearance, Clarence.

Wiki

Most information regarding Clearance is on the Github Wiki.

Engine

Clearance is a Rails engine. It works with versions of Rails greater than 2.3.

In config/environment.rb:

config.gem “thoughtbot-clearance”, :lib => ‘clearance’, :source => ‘http://gems.github.com’, :version => ‘0.6.4’

Vendor the gem:

rake gems:install rake gems:unpack

Make sure the development database exists and run the generator:

script/generate clearance

A number of files will be created and instructions will be printed.

You may already have some of these files. Don’t worry. You’ll be asked if you want to overwrite them.

Run the migration:

rake db:migrate

Environment

Define a HOST constant in your environment files. In config/environments/test.rb and config/environments/development.rb it can be:

HOST = “localhost”

In production.rb it must be the actual host your application is deployed to. The constant is used by mailers to generate URLs in emails.

In config/environment.rb:

DO_NOT_REPLY = “donotreply@example.com”

Define root_url to something in your config/routes.rb:

map.root :controller => ‘home’

Cucumber Features

As your app evolves, you want to know that authentication still works. Clearance’s opinion is that you should test its integration with your app using Cucumber.

In config/environments/test.rb:

config.gem ‘webrat’, :version => ‘= 0.4.4’ config.gem ‘cucumber’, :version => ‘= 0.3.0’ config.gem ‘thoughtbot-factory_girl’, :lib => ‘factory_girl’, :source => “http://gems.github.com”, :version => ‘1.2.1’

Vendor the gems:

rake gems:install RAILS_ENV=test rake gems:unpack RAILS_ENV=test

Don’t vendor nokogiri (due to its native extensions):

rm -rf vendor/gems/nokogiri-1.2.3

Run the Cucumber generator (if you haven’t already) and Clearance’s feature generator:

script/generate cucumber script/generate clearance_features

All of the files generated should be new with the exception of the features/support/paths.rb file. If you have not modified your paths.rb then you will be okay to replace it with this one. If you need to keep your paths.rb file then add these locations in your paths.rb manually:

def path_to(page_name) case page_name … when /the sign up page/i new_user_path when /the sign in page/i new_session_path when /the password reset request page/i new_password_path … end

Authors

Clearance was extracted out of Hoptoad. We merged the authentication code from two of thoughtbot’s client’s Rails apps and have since used it each time we need authentication. The following people have improved the library. Thank you!

Dan Croak, Mike Burns, Jason Morrison, Joe Ferris, Eugene Bolshakov, Nick Quaranto, Josh Nichols, Mike Breen, Marcel Görner, Bence Nagy, Ben Mabey, Eloy Duran, Tim Pope, Mihai Anca, Mark Cornick, & Shay Arnett.
