Re: How to do a generic field in an app.

So now, I'd like to do the following:

class AppConfig(models.Model):

    my_content_type = ForeighnKey(ContentType)

    <other_important_fields)

class Submission(models.Model):

    object_id = PositiveIntegerField()

    my_config = ForiegnKey(AppConfig)

    content_object = GenericForeignKey("my_config__my_content_type", "object_id")

But Django says the field cannot be found. I want the AppConfig structure separated from the actual Submission, but is there a way of doing this?

I want to have a model that has a foreignkey to a model from another app. The app can be one of many.

So far I've come up with a two field solution with:

model_type = ForeignKey(ContentType)

pk_field = PositiveIntegerField()

with an appropriate getter. Is there a better way to do this? It feels like this has already been solved in a known "good" way.
