NoMethodError with :has_many

Rails
1

Hi,
I have a problem in the guts of Rails. I have a :has_many association.
The :has_many method calls the method
“add_multiple_associated_save_callbacks” and this is where I have
problems. In the line “validate method_name” my application crashes with
a NoMethodError. What is the “validate” method? From which module does
it come?
Best regards
Bernd

Can you post the code?

The problem is that I have a class that inherits already from another
class and anyway I want to use some functions of some modules of the
ActiveRecord package in that class, e.g. from ActiveRecord::Associations
and
ActiveRecord::Associations::ClassMethods. So I call has_many :things and
then it crashes in line 979 of the file associations.rb of the
ActiveRecord library. The line has the content “validate method_name”.

Cheers
Bernd
