Answer 1

Building on ksol's post, you can ensure user.is_test by passing a block to authenticated:

authenticated :user, lambda {|u| u.is_test } do
    // route stuff here
end

This is assuming that u.is_test returns a Boolean value.

Answer 2

current_user is only available in your controllers and views. There is more than one way to achieve what you want, the easier being supplying it as a parameter to your method.

EDIT

if current_user if accessible in the router, you can pass it to your constraints class by doing constraints: APIRouter.new(current_user). Then you need to define APIRouter#initialize and store the current_user in an instance var that you can use in matches?.

EDIT 2

I just remembered devise allows you to do this in your router :

authenticated :user do
  root :to => "main#dashboard"
end

I don't know how to ensure that user.is_test though.

EDIT 3

Last attempt. request.env["warden"].user(:user) should give you a user if one is authenticated.

Answer 3

Just remember to add diff :as for both root otherwise it will through error

authenticated :user do
  root :to => "main#dashboard", :as => :foo
end

root :to => "main#landing_page"
