Django model one foreign key to many tables
You should use the contentypes framework in Django.
There's an example for a generic relation here :https://docs.djangoproject.com/en/1.8/ref/contrib/contenttypes/#generic-relationsFor your requirement it could look something like this:
from django.db import modelsfrom django.contrib.contenttypes.fields import GenericForeignKeyfrom django.contrib.contenttypes.models import ContentTypeclass Status(models.Model): request_type = models.ForeignKey(ContentType) request_id = models.PositiveIntegerField() request = GenericForeignKey('request_type', 'request_id')You can then do something like following:
status1 = Status(request=Request1("foo"))status1.save()status2 = Status(request=Request2("bar"))status2.save()status1.request // <Request1 "foo">status2.request // <Request2 "bar">
