Django ORM Model meta internal API to current API update

[Asif Saif Uddin]

Hi,

I have got an old project of django 1.8 which use codes like

links = [rel.get_accessor_name() for rel in self._meta.get_all_related_objects()]

How would I upgrade this code snippets to django 2.2 LTS?

TIA

I've poked around some of these dark corners, but only since the late 2.x series. After a bit of searching this find-the-field-that-connects-a-model-to-a-through-model and the linked

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.

HTH, Shaheed
