Create a method like current_user for devise's current resources

Question

I want to create a method like current_user for devise's current resources. Suppose I have two resources like User and Admin and devise is associated with both. So as usual it dynamically creates it's default methods like current_user and current_admin.

It creates it by defining like this in file lib/devise/controllers/helpers.rb:

def current_#{mapping}

How can I add a new method like this to it's dynamic methods.

I want to implement it with devise methods, so that when devise initializes then my method is also initialize with same mapping name.

Copy this code into your application controller. and your problem will solved.

Devise.mappings.each do |mapping, obj|
  define_method "current_#{mapping}_email" do
    eval("current_#{mapping}.email if current_#{mapping}")
end
helper_method "current_#{mapping}_email"

On view page/controller used according to your resource name like if you have resource_name as user then its 'current_user_email' or if have admin then 'current_admin_email'
