rails 3.1, how to add custom condition to after_filter?

Question

How can I add a custom condition for after_filter or before_filter

How can I have something like this:

after_filter :handle_student_time_tracking, :condition=> ( !current_student.nil? )

I can put the condition inside handle_student_time_tracking but, I think there is a better way Please advice

Answer 1

You should put the conditions in your filter, not on the after_filter call. Like this:

after_filter :handle_student_time_tracking

def handle_student_time_tracking
  raise "I'm in an after filter!" if current_student.present?
end

The conditions that filters provide are for actions, like only and except, not based on other conditions.
