After a bit of searching this find-the-field-that-connects-a-model-to-a-through-model <https://stackoverflow.com/questions/52334086/find-the-field-that-connects-a-model-to-a-through-model> and the linked <https://stackoverflow.com/questions/52280584/any-way-to-fetch-the-through-fields-for-an-object-linked-via-many2many-field-wit/52283964#52283964> suggest these are/were private APIs and AFAIK, the best you can do is try to figure out what the old code was doing, and rework them using the likes of: - self._meta.related_objects - self._meta.fields_map - self._meta.local_many_to_man and the other similarly named fields. One thing to note: if a field x points to a *set* of objects, you won't find a "self.x", but rather a "self.x_set" which must be followed using a query such as "self.x_set.all()" rather than a simple field dereference.
