Sorcery

Here are listed community proposed solutions to solve Sorcery and RailsAdmin compatibility:

Authentication

This was proposed by David Tuite on SO

Authentication with Sorcery requires manual tweaking of rails_admin.rb initializer.

RailsAdmin.config do |config|
  config.authenticate_with do
    # Use sorcery's before filter to auth users
    require_login
  end
  config.current_user_method(&:current_user)
end

You will also need to update the not_authenticated in your application_controller.rb:

class ApplicationController
  # Overwrite the method sorcery calls when it
  # detects a non-authenticated request.
  def not_authenticated
    # Make sure that we reference the route from the main app.
    redirect_to main_app.login_path
  end
end

Solving incompatibility with authentication in production

There's a solution proposed by @adamkangas, for context, see #147

This requires forcing Sorcery::Controller inclusion at the end of sorcery.rb initializer:

ActionController::Base.send(:include, Sorcery::Controller)
