Hi all! I'm new to django and I'm experimenting with models but I have some trouble. I've minimized my problem to this code:
class TestBase(models.Model): base = models.CharField(max_length=255) from django.contrib import admin class TestA(TestBase): testb = models.CharField(max_length=255) admin.site.register(TestA) class TestB(TestBase): testc = models.CharField(max_length=255) admin.site.register(TestB) Trying to add TestA instances from admin interface I have this error: Cannot assign "''": "TestA.testb" must be a "TestB" instance. why testb should be a TestB instance?? It's a simple field! If TestBase is declared as abstract using the internal Meta Class I no more have the error. Is this a bug or there is something that I don't understand?
