Comment (by Tim Graham):

 We can't add code for a problem we don't fully understand, or else Django
 would quickly become a mess. Without a test, we can't be sure the problem
 is fixed and that the behavior won't regress in the future.

 Yea, I've tried to come up with something, but no luck so far.  I've only
 been able to get this to fail on my project, and like I said, it has
 hundreds of objects with complex relations.  The code does fix the problem
 and I see no downside to ordering proxy model and model creates at the top
 before the sort, any reason not to just accept the PR?

 Not sure if I'll be able to come up with something here.

 You'll need to provide a minimal example to reproduce the issue so we can
 better understand it. The patch also requires a regression test based on
 that.

 I've been having trouble regenerating all my Django migrations from
 scratch. We have hundreds of models and many complex relationships. I kept
 getting the error `Cannot resolve operation dependencies` when generating
 and I noticed that proxy models that were foreign keys of other models
 seemed to be the culprit. I've created a pr to fix the sort method to
 ensure that proxy model based CreateModel and regular model CreateModel
 operations are at the top.
