I discovered tonight that when you create a manipulator from a model that contains a ForiegnKey field, it generates a SelectField and pre-populates the form field object's choices attribute with all the possible values. So far so good . . . except that the primary key in the related table is an AutoField, so it shouldn't be possible to assign to it.
Is this a bug? Is there a way to suppress this behavior? I tried assigning limit_results_to in the model definition but that doesn't seem to apply to the creation of the form field. This is a performance concern, since I'm seeing a noticeable pause (3 or 4 seconds) with only 50K rows in the DB . . . I can't imagine how painful this would be with 10x or 100x the data. TK
