Routes Constraints - Sorcery/sorcery GitHub Wiki
This tutorial shows how to use Rails routes constraints with Sorcery gem. Thanks to @anthonator for writing it!
First, define UserConstraint
module that will be used for all constraints:
module RouteConstraints::UserConstraint
def current_user(request)
User.find_by_id(request.session[:user_id])
end
end
Then, having that module defined, you can specify specific constraint classes. In these examples, first route will work only if there's no user logged in, the second will work only for logged user who is an admin:
class RouteConstraints::NoUserRequiredConstraint
include RouteConstraints::UserConstraint
def matches?(request)
!current_user(request).present?
end
end
class RouteConstraints::AdminRequiredConstraint
include RouteConstraints::UserConstraint
def matches?(request)
user = current_user(request)
user.present? && user.is_admin?
end
end
Finally, you can add the constraints to the config/routes.rb
:
MyApp::Application.routes.draw do
# other routes …
root :to => 'admin#dashboard', :constraints => RouteConstraints::AdminRequiredConstraint.new
root :to => 'home#welcome', :constraints => RouteConstraints::NoUserRequiredConstraint.new, as: nil
end
