FieldError when migrating field to new model subclass. Description Analogous to #21890. If creating a model subclass and moving a field onto it in the same step, makemigrations works but migrate dies with django.core.exceptions.FieldError: Local field 'title' in class 'Book' clashes with field of the same name from base class 'Readable'. For example, take this model: from django.db import models class Readable(models.Model): title = models.CharField(max_length=200) And change to this: from django.db import models class Readable(models.Model): pass class Book(Readable): title = models.CharField(max_length=200) The migration generates with CreateModel for Book, then RemoveField for Readable.title. But running it produces the error. Reversing the order of the migration operations makes it pass. The auto-detector should be able to use this order. Work only inside this repository checkout. Make the code change the task describes, keeping the diff focused — no drive-by refactors. When you are done, leave your changes committed or in the working tree; they are collected automatically. Stay on this snapshot checkout (`task/ycb_django_pr12754`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan. Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.
Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
