Could not find user with id = 1

Question

I have a current_user method for authentication.

application_controller.rb

 protect_from_forgery helper_method :current_user def current_user @current_user ||= User.find(session[:user_id]) if session[:user_id] end 

but when I try to connect to the page, I get the following error:

 Couldn't find User with id=1 app/controllers/application_controller.rb:10:in `current_user' 

How to pass @current_user its default value, so if there is no user, it will be redirected to the login page.

Thanks for the help.

It looks like your session contains old data, specifically a user ID (1) that no longer exists. Try to handle the RecordNotFound exception RecordNotFound by ActiveRecord and return zero:

 def current_user @current_user ||= User.find(session[:user_id]) if session[:user_id] rescue ActiveRecord::RecordNotFound end 

To redirect, you must add a second before_filter that validates the user and handles the redirection to the login path:

 before_filter :require_user def require_user redirect_to login_path unless current_user end 

Remember to skip require_user for your login action by adding skip_before_filter :require_login to which controller manages your authentication.
