I've got two models. Here's what I'm trying to do: class InterestSet(models.Model, MailChimpAPIMixin): name = models.CharField(help_text="The interest grouping to add. Grouping names must be unique.", max_length=128, unique=True) content_type = models.ForeignKey(ContentType, blank=True, null=True)
class InterestGroup(models.Model, MailChimpAPIMixin): name = models.CharField(max_length=128, unique=True) interest_grouping = models.ForeignKey(InterestGrouping) object_id = models.PositiveIntegerField(blank=True, null=True) content_object = generic.GenericForeignKey('interest_set__content_type', 'object_id') Basically, I want to define a content type for an Interest Set on the "parent" model. Then, for each Interest Group, I want the object id to always refer to the content type set on Interest Set. You can see by the first argument to GenericForeignKey() how I wish it worked. Alas it does not. Plan B is just to move the content_type field back to Interest Grouping and deal (or possibly just custom code my relationships without relying on GenericForeignKey). It's a shame because it duplicates data unnecessarily and creates an opportunity for a relationship to be created that violates a business rule for this application (which is that all Interest Groups in an Interest Set must be related to the same content type). I'm just wondering if either a) I'm missing an obvious way to accomplish this or b) this has come up before or been discussed somewhere. I might explore the possibility of patching the source code to enable this behavior of that sounds at all desirable. Let me know your thoughts.
