Devise Masquerade

It's a utility library for enabling functionallity like login as button for admin.

If you have multi users application and sometimes you want to test functionally using login of existing user without requesting the password, define login as button with url helper and use it.

Installation

Add this line to your application's Gemfile:

gem 'devise_masquerade'

And then execute:

$ bundle

Usage

In the view you can use url helper for defining link:

= link_to "Login As", masquerade_path(user)

Add into your application_controller.rb:

before_filter :masquerade_user!

Instead of user you can use your resource name admin, student or another names.

If you want to back to the owner of masquerade action user you could use helpers:

user_masquerade? # current user was masqueraded by owner?

= link_to "Reverse masquerade", back_masquerade_path(current_user)

Custom controller for adding cancan for authorization

class Admin::MasqueradesController < Devise::MasqueradesController
  def show
    authorize!(:masquerade, User)

    super
  end
end

Custom url redirect after masquerade:

class Admin::MasqueradesController < Devise::MasqueradesController
  def show
    authorize!(:masquerade, User)

    super
  end

  protected

  def after_masquerade_path_for(resource)
    "/custom_url"
  end
end

You can redefine few options:

Devise.masquerade_param = 'masquerade'
Devise.masquerade_expires_in = 10.seconds
Devise.masquerade_key_size = 16 # size of the generate by SecureRandom.base64

Demo project

cd spec/dummy
rake db:setup
rails server

And check http://localhost:3000/, use for login user1@example.com and 'password'
