Description
I have a strange issue with When() and models using UUID as their pk.
I prepared example project here: https://github.com/dekoza/djanbug
The example.views.myview includes code ported from the app I'm currently developing - I have several models using UUIDs as their PK and I need to do some annotations an aggregations with some specific cases handled with Case()/When() combo.
Even though the db is empty on the example, the view crashes that '1' is not a valid UUID. and the only '1' is the one in When()
I've also encountered issues with Count('*', distinct=True) but right now I'm trying to reproduce it on the example and will post another ticket when I'm done.
