DEFAULT_AUTHENTICATION =

RailsAdmin is setup to try and authenticate with warden If warden is found, then it will try to authenticate

This is valid for custom warden setups, and also devise If you’re using the admin setup for devise, you should set RailsAdmin to use the admin

Proc.new do
  request.env['warden'].try(:authenticate!)

  else
    @audit = block if block
  end
  @audit || DEFAULT_AUDIT
end

.authenticate_with(&blk) ⇒ Object

Setup authentication to be run as a before filter This is run inside the controller instance so you can setup any authentication you need to

By default, the authentication will run via warden if available and will run the default.

If you use devise, this will authenticate the same as authenticate_user!

Examples:

Devise admin

RailsAdmin.config do |config|
  config.authenticate_with do
    authenticate_admin!
  end
end

Custom Warden

RailsAdmin.config do |config|
  config.authenticate_with do
    warden.authenticate! :scope => :paranoid
  end
end

end

.authorize_with(*args, &block) ⇒ Object

Setup authorization to be run as a before filter This is run inside the controller instance so you can setup any authorization you need to.

By default, there is no authorization.

To use an authorization adapter, pass the name of the adapter. For example, to use with CanCan, pass it like this.

See the wiki for more on authorization.

Examples:

Custom

RailsAdmin.config do |config|
  config.authorize_with do
    redirect_to root_path unless warden.user.is_admin?
  end
end

CanCan

RailsAdmin.config do |config|
  config.authorize_with :cancan
end

end

.configure_with(extension) {|configuration| ... } ⇒ Object

Setup configuration using an extension-provided ConfigurationAdapter

Examples:

Custom configuration for role-based setup.

RailsAdmin.config do |config|
  config.configure_with(:custom) do |config|
    config.models = ['User', 'Comment']
    config.roles  = {
      'Admin' => :all,
      'User'  => ['User']
    }
  end

end

.current_user_method(&block) ⇒ Object

Setup a different method to determine the current user or admin logged in. This is run inside the controller instance and made available as a helper.

By default, _request.env.user_ or current_user will be used.

Examples:

  config.current_user_method do
    current_admin
  end
end

.model(entity, &block) ⇒ Object

Loads a model configuration instance from the registry or registers a new one if one is yet to be added.

First argument can be an instance of requested model, its class object, its class name as a string or symbol or a RailsAdmin::AbstractModel instance.

If a block is given it is evaluated in the context of configuration instance.

Returns given model’s configuration
