Rails authentication with email & password.
Clearance is included in Suspenders, which thoughtbot uses on all of our apps. We highly recommend you try it. Suspenders is the “King Gem” in our ecosystem, representating what we think the current state-of-the-art is in Rails development.
Clearance is a Rails engine. It works with versions of Rails greater than 2.3.
config.gem "thoughtbot-clearance", :lib => 'clearance', :source => 'http://gems.github.com', :version => '0.8.2'
Vendor the gem:
rake gems:install rake gems:unpack
Make sure the development database exists and run the generator:
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:
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.
DO_NOT_REPLY = "email@example.com"
Define root_url to something in your config/routes.rb:
map.root :controller => 'home'
As your app evolves, you want to know that authentication still works. thoughtbot’s opinion is that you should test its integration with your app using Cucumber.
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
We have begun standardizing our forms using Formtastic. We highly recommend trying it. It will make your Rails view life more interesting.
Clearance has another generator to generate Formastic views:
Its implementation is designed so that other view styles can be generated if the community wants it. However, we haven’t needed them so you’ll have to write the patch and send it back if you want other styles (such as Haml).
Clearance was extracted out of Hoptoad. We merged the authentication code from two of thoughtbot’s clients’ Rails apps and have since used it each time we need authentication. The following people have improved the library. Thank you!
