Overridable fields for Proxy models
Allow overriding fields on Proxy models.
Mostly, you won’t want to do this. However, I did have a situation where it would be useful, mainly for reducing the numbers of queries I was having to run.
You can read about it at: http://schinckel.net/2015/05/13/django-proxy-model-relations/
Usage is pretty simple:
- class ProxyModel(ParentModel):
- related = ProxyForeignKey(OtherProxyModel)
You may only override fields that exist, although in the future, it may be possible to create a relation with a different name (enabling you to keep the standard relation to the non-proxy model).
You may also only override with a compatible field, and can only point to another proxy model (and only one proxy model may point to any other given proxy model).
It is also possible to override non-related models, but I’m not that interested in that use case at the moment.
