Combine custom validations with helpers


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

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

def ensure_some_stuff
# custom error checking here



Great, exactly the kind of solution I was looking for. Thanks.
