This doesn't seem to be a Django repository. The task asks to solve a GitHub issue from django/django repository. Let me check if this is a separate task that just needs a patch generated based on the issue description.

Based on the issue description and the hints provided, I need to generate a patch for the Django codebase. The fix is clearly described in the hints - the issue is in `django/db/models/sql/compiler.py` around line 727, where `name` should be replaced with `pieces[-1]` in the comparison.

Let me generate the patch based on the information provided:
