Validates Existence plugin

Plugin details

This plugin adds a new validates_existence_of method to ActiveRecord::Base.

The validates_existence_of validator checks that a foreign key in a belongs_to association points to an exisiting record. If :allow_nil => true, then the key itself may be nil. A non-nil key requires that the foreign object must exist. Works with polymorphic belongs_to.
