@rpkilby Great stuff!
I think we just need to document the existence of WrappedAttributeError — the why and what you'd do with it.
A good place for that would be in the Custom Authentication section.

@rpkilby we cannot really reproduce it now any more since our code has fixed the AttributeError and changed quite a bit since we originally reported this. But yes, just raising an Looking at the PR and test I think this PR does the right thing :) |

Fixes #4033. There is an existing test for the issue, however there are a couple of issues:
request.useris never set. Because of this,__getattribute__will re-raise theAttributeError. However, typical use does include an authentication middleware and will yield auseron the underlying request, as demonstrated by Suppressed AttributeError When Authenticating #4033.SessionMiddlewareis applied to the DRF request object instead of the underlying Django request, which doesn't mirror how middleware is actually applied.
