Ruby on Rails

Hello,

I am lil bit confused.
Will this help on returning back to the admin user again?

#users_controller.rb
  before_filter :authenticate_impersonator!, :only => [:index, :impersonate, :stop_impersonating]

  def impersonate
    session[:impersonating] = params[:practice_id]
    redirect_to( '/calendar' )
  end
 
  def stop_impersonating
    session[:impersonating] = nil
    redirect_to( '/users/index' )
  end

  def authenticate_impersonator!
    redirect_to(:root) unless (can? :impersonate, User)
  end

#application_controller.rb
  helper_method :current_practice
  def current_practice
    if session[:impersonating]
      Practice.find session[:impersonating]
    else
      current_user.practice
    end
  end

#views/layouts/index.html.erb

<%- if session[:impersonating] -%>
<div id="impersonating">
        <p>Currently impersonating <strong><%= current_practice.name %></strong> <%= link_to "Stop Impersonating", "/users/stop_impersonating", :class => "form_button delete" %></p>
</div>
<%- end -%>


Everything in this solution centers around the current_practice helper, which is where I used the session to side-step the current user and pretend to be another.

I hooked into the current_user method and allowed an admin user to assume the identity of another user without logging out. Since admins were allowed to see everything anyway (in CanCan) I didn't need to do anything special besides store the ID of the account I was impersonating in the session.
