Only works with Rails >= 4.2

[Carlos Ramirez III]

The ValidatorProxy object calls validate on the Active Record model, however this method was added to the Active Record API in Rails 4.2.

For Rails versions 4.1 or below, a NoMethodError: undefined method 'validate' is raised.

Since validate is an alias for valid? perhaps a fix would be to use valid? instead?
