How do I handle authentication with Devise when using multiple models in Rails 3.2 App

I\'m working on a Rails 3.2 app where I use Devise for authentication. I decided to try single table inheritance for managing user roles, but I quickly ran into a problem. I cur

Answer 1

Not sure if this is still needed a solution to this...

A more elegant way to have the double authentications could be to do the following:

private

def authenticate!
   :authenticate_admin! || :authenticate_collaborator!
   @current_user = admin_signed_in? ? current_admin : current_collaborator
end

Then call before_filter :authenticate!

If you dont need a universal '@current_user' variable just leave out the second line.

Hope this helps.

You can solve this using the following solution

def authenticate!
    if modelA_user_signed_in?
      @current_user = current_modelA
      true
    else
      authenticate_modelB!
    end

  end

You may separate all common logic to module and use only same table.

module UserMethods
  #...
end

class User < ActiveRecord::Base
  include UserMethods
  devise ...

end  

class Admin < ActiveRecord::Base
  include UserMethods
  self.table_name = "users"
  devise ...
end

And configure all devise model separately in routes, views(if necessary, see Configuring Views). In this case, you may easy process all different logic.
