Django proxy model and ForeignKey

Question

How to make entry.category to be instance of CategoryProxy? See code for details:

class Category(models.Model): pass

class Entry(models.Model):
    category         


        

Answer 1

Adapting Bernd Petersohn's answer slightly, we then have:

class EntryProxy(Entry):
    @property
    def category(self):
        return CategoryProxy.objects.get(id=self.category_id)

This ought to be more economical with the database. For added improvements you could set a private attribute (self._category) the first time the method is called, then return that all subsequent times.
