The same current_user on multiple models in devise

Question

Problem

I have a User model, and the Volunteer model that inherits from the User model:

class User < ActiveRecord::Base
end

class Volunteer <         


        

Answer 1

perhaps a little to late but you can try the following in your routes.rb

devise_for :users , :skip => :registrations
as :user do
    match "volunteers/edit(.:format)", :to => "devise/registrations#edit"
end
devise_for :volunteers , :skip => :sessions

The above code assumes that all users and its subclasses (assuming what you are implementing STI to achieve Users model hierarchy) can sign_in and sign_out, but only volunteers can register. Since a volunteer is a user, the user should be able to edit his registration as such. You can add more routes inside the as :user block.

Answer 2

I faced similar problem and solved it like this. But is this solution is specific for cancan gem.

application_controlller.rb

def actual_user
  @actual_user ||= current_user.present? ? current_user : current_volunteer
end

def current_ability
  @current_ability ||= Ability.new(actual_user)
end

Answer 3

I think this way you allow a user to be signed in as a User and a Voluteer in the same session.

Once you have a way to deal with that could you not just have

# in application_controller.rb
alias_method :devise_current_user, :current_user
def current_user
  devise_current_user || current_volunteer
end

in your application_controller.rb

Answer 4

I have accepted viktor tron's answer beacuse it seems the cleanest method.

However, i have resolved my issue in a different way.

I've ended up hardcoding the sign in process for other classes as :user. This gives me access to the current_user method even for the volunteer class.

class Volunteers::SessionsController < Users::SessionsController

  def create
    resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new")
    if resource
      flash[:notice] = "You are logged in"
      sign_in(:user, resource)
      super
    else
      super
    end
  end

end
