I use devise plugin and there is current_user helper. My users can have many profiles in application so User have has_many :profiles and always one of them is active.

How, and where can I create helper current_profile?

In the User class I would add a method

class User
  has_many :profiles

  def current_profile
    @current_profile ||= profiles.where('current = ?', true).first
  end
end

and then inside your controller/helpers you could just write:

current_user.current_profile

Hope this helps.

As far as how, is really just a matter of figuring out which profile is active (I'm assuming that a user can ONLY have 1 active profile in a given session - that will make it easier). So, what you do is use your session info to find out the current user, then find the active profile, and bingo - you're done.

As far as where, that's really a question of scope. If you want to have the helper method available to any view, simply declare it in the application controller, and you should be good.

You can create the helper in ApplicationController, which will make it available to all controllers and views that inherit from it:

class ApplicationController < ActionController::Base  
  protect_from_forgery  
  helper_method :current_profile  

 private  
  def current_profile  
    # get current_profile based on current_user here
  end  
end

Now you can use current_profile in any views/controllers.
