12580	New validations pulls all elements for foreignkeys	Jani Tiainen	nobody	"Model validation added {{{ validate() }}} method on {{{ forms.fields.Field }}}. This method is called in a validation call chain from {{{ ModelChoiceField }}}. validate() method is only in {{{ ModelChoiceField }}} which inherits {{{ ChoiceField }}}. {{{ validate() }}} method pulls in all data from foreign key model by using expensive for loop.

Model forms and admin forms both suffer from this feature. Specially admin forms with raw_id_field when referring to model that contains millions of rows.
