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

Any update_attribute in an after_save callback will cause recursion, in Rails3+. What should be done is:

after_save :updater
# Awesome Ruby code
# ...
# ...

private

  def updater
    self.update_column(:column_name, new_value) # This will skip validation gracefully.
  end
