I fixed that problem (a bit different) for the current master (1.3.0.beta) in #72 . After merging my pull request this pull request can AFAICS be closed. |

Currently, uniqueness validation check is done by calling
resource.model.first, which only scopes the query to that particular class. This patch usesproperty.modelinstead to scope the query to the class in which the property was defined and its children.This is the best solution that I could find. There is no easy way to scope the query to the class which calls
validates_uniqueness_of, only the class that defines the property.
