Rails how to update a column after saving?

Question

I want to create an after_save method for my rate action. It would divide rating_score/ratings and update the column rating.

class KonkurrancersController &         


        

Answer 1

Not sure why people are upvoting the wrong answer and downvoting the correct answer.

Zakelfassi is right and Christian Fazzini is wrong for Rails 3 and above. If you do #update_attributes in a save callback you go into an endless recursion. You want to do #update_column as per his example.

Try it for yourself and you'll see.
