AnyLogin was created to speed up the development process by allowing developers to quickly log in as any user.

Give it a try; if you like it please share AnyLogin with friends. If you have any suggestions please feel free to contact me.

Ruby: 1.9.3, 2.X, Rails: >= 4.0. Pre-configured to work with Devise, Authlogic, Clearance or Sorcery gems.

For Rails < 4.2.7 please use gem 'any_login', '1.3'.

1. Add AnyLogin to your Gemfile:

   gem 'any_login'
   

2. Execute in console:

   bundle install
   

3. In application layout (for example app/views/layouts/application.html.erb) add the following to the bottom of the page:

   = any_login_here if defined?(AnyLogin)
   

4. Open your app and on the bottom left corner you will see semi-transparent user icon. Click on it and now you can select any user to log in as without a password.

After defining a class method called primary_key, any_login works seamlessly. Otherwise, you will see this error undefined method 'primary_key' for User:Class

class User
  ...

  class << self
    def primary_key
      # if your primary key is :id, if anything else use accordingly.
      :id
    end
  end
end

By default no additional steps are required to make it work with Devise gem. If you have a User model everything should work fine. If you have different user model you need to set it in options (see Customization section).

By default no additional steps are required to make it work with Authlogic gem. If you have a User model and a current_user method in application controller everything should work fine. If you have different user model you need to set it in options (see Customization section).

By default no additional steps are required to make it work with Clearance gem. If you have a User model everything should work fine. If you have different user model you need to set it in options (see Customization section).

By default no additional steps are required to make it work with Sorcery gem. If you have a User model everything should work fine. If you have different user model you need to set it in options (see Customization section).

If you are utilizing a custom login strategy, you can also utilize it with this gem. Below is an example configuration if a user was utilizing OmniAuth and rails sessions directly as described in this article:

In app/lib/anylogin_omniauth.rb

module AnyloginOmniauth
  module Controller
    def self.any_login_current_user_method
      @@any_login_current_user_method ||= "current_#{AnyLogin.klass.to_s.parameterize.underscore}".to_sym
    end

    def any_login_sign_in
      session[:user_id] = user_id
      redirect_to main_app.send(AnyLogin.redirect_path_after_login)
    end
  end
end

Then in your initializer configure provider to your new class. In this example it would be config.provider = "AnyloginOmniauth"

If you want to customize gem execute in console:

rails g any_login initializer

It will create the initializer file config/initializers/any_login.rb.

• enabled - enable or disable gem (by default this gem is enabled only in development mode).
• klass_name - class name for "User" object. Defaults to User.
• collection_method - method which returns collection of users. Sample: .all, .active, .admins, .groupped_users. Value is a simple. Defaults to :all.
• name_method - default value is proc { |e| [e.email, e.id] }. You can change the label of users displayed in dropdown. For example you can add roles, permissions and any other important information.
• limit - limit number of records in dropdown. Default 10. You can put :none if you don't want to limit the number of users for select.
• redirect_path_after_login - redirect user to path. Default is :root_path.
• login_on - you can enable login with select field, ID input or both. Default: :both.
• position - position of AnyLogin box on page. Possible values: top_left, top_right, bottom_left, bottom_right. Default: bottom_left.
• login_button_label - login button label.
• select_prompt - select prompt message.
• auto_show - automatically show AnyLogin box.
• http_basic_authentication_enabled - Enable HTTP_BASIC authentication.
• http_basic_authentication_user_name - HTTP_BASIC authentication user name.
• http_basic_authentication_password - HTTP_BASIC authentication password.
• verify_access_proc - controller based access (condition on request.remote_ip, current_user, etc.)
• previous_limit - specify limit of records for history. Default: 6.
• provider - Manually specify the login provider, one of Authlogic, Clearance, Devise, Sorcery, or a custom handler class name (as a string or symbol).

If you want to display users grouped by role you can do it with:

# Initializer: config/initializers/any_login.rb
AnyLogin.setup do |config|
  config.collection_method = :grouped_collection_by_role
end

# User class: app/models/user.rb
class User < ActiveRecord::Base
  def self.grouped_collection_by_role
    {
      'admin'     => User.admins.limit(10),
      'moderator' => User.moderators.limit(10),
      'user'      => User.users.limit(10)
    }
  end
end

Or another sample:

# Initializer: config/initializers/any_login.rb
AnyLogin.setup do |config|
  config.collection_method = :grouped_users
  # to format user name in dropdown list
  config.name_method = :any_login_name
end

# User class: app/models/user.rb
class User < ActiveRecord::Base
  def any_login_name
    [full_name + ' - ' + email + " Domains: #{domains.collect(&:short_code).join(',').presence || 'none'}; Role: #{role}; ID: #{id}", id]
  end

  def self.grouped_users
    Organization.ordered.includes(:employees).inject({}) do |res, org|
      res[org.name] = org.employees.ordered.includes([:domains, :organization])
      res
    end
  end
end

If you want to completely disable gem in production add following code in your config/environments/production.rb file.

AnyLogin.setup do |config|
  config.enabled = false
end

You can also try to debug your application in production and secure AnyLogin with HTTP_BASIC authentication. See Options sections for more details.

1. Add tests
2. Add support for more authentication gems like Devise, Authlogic, Clearance (restful_authentication, monban, letmein)
