Rails 3.2 update attribute after save

Question

I want to update an specific attribut in my database after save data.

For example i have an column in my table which called pending and it's an boolean. i want to set this value to true when data was saved.

after_save :do_something

private
def do_something
  self.update_column(:pending, true)
end

This doesn't work. Anyone here who has an solution?

why don't you try before_save? – maximus ツ Apr 03 '13 at 09:50 — maximus ツ, Apr 03 '13 at 09:50
just write self.pending = true in it. – maximus ツ Apr 03 '13 at 09:58 — maximus ツ, Apr 03 '13 at 09:58
you need to add attr_accessor :pending to model. – maximus ツ Apr 03 '13 at 10:08 — maximus ツ, Apr 03 '13 at 10:08
This works fine when i use before_save. Thanks – pkberlin Apr 03 '13 at 10:11 — pkberlin, Apr 03 '13 at 10:11

You can modify your attribute directly like:

after_save { |user| user.username = user.username.downcase }

Try after_commit instead of after_save. It will operate outside of the save transaction.
