Question

I’m using Rails and Devise gem. I want to PayPal account.

I have function:

  def verify_paypal
............
   end

I put it into user.rb. Added route, in routes.rb:

devise_for :users do
  member do
  get 'verify_paypal'
  end
end

and get error

  /mapper.rb:1189:in `member': can't use member outside resource(s) scope (ArgumentError)

What I’m doing wrong ?

Answer 1

First, you cannot call a block on devise_for, it is not setup this way. Devise does provide a helper method that you can use that allows you to call a block on Devise routes. See the README.

Second, Devise routes and scoping Devise routes, is only for Devise routes. Your method is not in any of the Devise controllers, therefore it cannot be called for Devise. You need to have a separate users_controller.rb with a method to call verify_paypal on the model. You can then setup your custom route in a block call on resources users. For more information on the Rails routing stack I would recommend reading, Rails Routing From the Outside In. This should give you all the information you need to make a call to your custom action.
