Question

I am trying to make a before_save in a rails app conditional, but it doesn’t seem to be working.

before_save method_call_to_run if self.related_model.some_method_that_returns_t_or_f?

If the ‘some_method_that_returns_t_or_f’ returns true, I want it to run the method before it saves the object otherwise I just want it to ignore the before_save.

Answer 1

you can use :if

before_save do_something, :if => Proc.new {|model| model.some_boolean_attr_or_method }

or simply

before_save do_something, :if => some_condition

EDIT:

for a quick reference, there’s an excellent guide about this:
