Polymorphic models with fields with optimizer hints aren't resolved correctly #733
Description
Describe the Bug
When using an annotated field with any optimizer hints, the optimizer attempts to load the fields with a prefix app_label__ModelName___ (here). This works perfectly for related field resolution, however it does not work for the hints. They are resolved like this:
app_label__ModelName_____someField (note that there are 5 underscores)
This causes django to try to prefetch an empty field and crashes.
System Information
- Operating system: Any
- Strawberry django version: 0.58.0
Additional Context
I've created a small reproduction here with the file in question: graphql.py
I'll continue trying to find the cause and might open a PR with a fix. Not sure if I'll be able to though...
