How to set a resource in another controller?

Question

I am trying to display a view of the default edit registration in modal mode. The modal is called from another controller .. Home_controller in this case.

I have <% = render: template, 'devise / registrations / edit'%> in my modal tag, and it is called when the mod’s launch button is clicked, but the rails through me use the undefined variable method as regards resource usage. I know that a resource is just a user-defined object, but the home compiler does not know how to solve it, I thought that the rendering template method allows this resolving rail to use the application registration controller.

Any ideas? Im really eanting to keep deafault designing a controller to simplify future functions? How to cause viewing from another controller in one controller, allowing you to use all the actions in the called controller.

Try adding this to application_helper.rb (from The Devise Wiki )

def resource_name :user end def resource @resource ||= User.new end def devise_mapping @devise_mapping ||= Devise.mappings[:user] end
