Usage

The following applies to Clearance >= 0.11.0.

Write your own tests with Clearance's helpers

sign_in_as, sign_out, should_deny_access and more helpers are available in your test suite. Look in controller_helpers.rb and deny_access_matcher.rb for the full list.

context "when signed in on GET to new" do
  setup do
    @user = Factory(:email_confirmed_user)
    sign_in_as @user
    get :new
  end
  should_respond_with :success
end

Authorize users for controller actions

If you want to authorize users for a controller action, use the require_login method in a before_action.

class WidgetsController < ApplicationController
  before_action :require_login

  def index
    @widgets = Widget.all
  end
end

Hooks: return_to parameter

Upon successful login, clearance will redirect the user to the page they were denied access, to the default redirect URL configured in the clearance initializer, or the URL specified in an overridden sessions#url_after_create method.

If you want to have a sign in form on every page and redirect the user to the same page after sign in, you can add a before_filter that sets the session[:return_to] value.

Hooks: url_after_create, url_after_update, url_after_destroy

Actions that redirect (create, update, and destroy) in Clearance controllers are customizable. If you want to redirect a user to a specific route after signing in, overwrite the "url_after_create" method:

class SessionsController < Clearance::SessionsController
  protected
  def url_after_create
    new_blog_post_path
  end
end

You'll also need to add an appropriate declaration in your config/routes.rb file to tell your app to use your overriding controller instead of the controller inside Clearance's engine. Following the example above, to override Clearance's sessions controller, you'd add this to your config/routes.rb file (before the Clearance::Routes.draw(map) call):

resource  :session,
  :controller => 'sessions',
  :only => [:new, :create, :destroy]

You also need to add code such as the following to your routes.rb:

match '/sign_out' => 'sessions#destroy', :via => :delete 

There are similar methods in other controllers as well:

• UsersController#url_after_create (sign up)
• SessionsController#url_after_create (sign in)
• SessionsController#url_after_destroy (sign out)
• PasswordsController#url_after_create (password reset)
• PasswordsController#url_after_forbidden (user clicks link in password reset email after resetting)
• PasswordsController#url_after_update (password)
• ConfirmationsController#url_after_create (confirmation)

Hooks: sign_in

Say you want to add a last_signed_in_at attribute to your User model. You would want to update it when the User signs in.

Clearance has a method named sign_in that you can overwrite with that logic. Be sure to write tests!

class ApplicationController < ActionController::Base
  include Clearance::Authentication

  # sign_in needs to be public for the `sign_in_as` controller spec helper to work
  hide_action :sign_in

  def sign_in(user)
    # store current time to display "last signed in at" message
    user.update_attribute(:last_signed_in_at, Time.now) if user
    super user
  end
end
