Question

I have a custom validation method that I only want executed on create:

validate :post_count, :on => :create

def post_count
  # validate stuff
end  

However, it’s getting fired on update (in addition to on create).

Does the :on => :create option not work with custom validation methods?

Answer 1

As far as I know, there’s no :on option. Use

validate_on_create :post_count

instead. And there’s validate_on_update also. You can read about this methods here.
