Rails authentication with email & password.
Fork away and create a Github Issue.
Clearance is a Rails engine. It works with versions of Rails greater than 2.3.
Install it as a gem however you like to install gems. Gem Bundler example:
Make sure the development database exists and run the generator:
- inserts Clearance::User into your User model
- inserts Clearance::Authentication into your ApplicationController
- inserts Clearance::Routes.draw(map) into your config.routes.rb
- created a migration that either creates a users table or adds only missing columns
- prints further instructions
If you want to authenticate users for a controller action, use the authenticate method in a before_filter.class WidgetsController < ApplicationController before_filter :authenticate def index @widgets = Widget.all end end
Subclass and override any Clearance-provided controller as needed:class SessionsController < Clearance::SessionsController def url_after_create new_blog_post_path end end
Actions that redirect (create, update, and destroy) in Clearance controllers
can be overriden by re-defining url_after_(action) methods as seen above.
Optional Cucumber features
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
Optional Formtastic views
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!
