Combine custom validations with helpers

rubyonrails-talk

Hi

I have a model that uses several validation helpers, for example validates_presence_of. Now I want to add a custom validate method for a very complex validation. I override validate in the model and it works by itself but when I do this the helper validations stop working. I guess the helper methods rely on the ActiveRecord::Base#validate original method in some way. Has anyone any suggestions on how to use both a custom validate and validations helpers?

Thanks in advance.

Instead of overriding the validate method call validate and pass it the name of your custom validation method. Here is an example:

class Foo < ActiveRecord::Base   validates_presence_of :bar   validate :ensure_some_stuff

  private   def ensure_some_stuff     # custom error checking here     ....   end end
