* version: 2.2 => master * component: Uncategorized => Migrations * stage: Unreviewed => Accepted Comment: There's a lot of history in here, so it may turn out this is a duplicate, but I'll accept this for now, as there's certainly a bug. `makemigrations` generats this: {{{ dependencies = [ ('testapp1', '0002_app1_another_app'), ] operations = [ migrations.AlterField( model_name='app1', name='another_app', field=models.ForeignKey(blank=True, null=True, on_delete=django.db.models.deletion.SET_NULL, to='testapp2.App2', verbose_name='another app'), ), ] }}} But that gives the `ValueError` as you say. Adjusting `dependencies` allows the test to pass: {{{ dependencies = [ ('testapp1', '0002_app1_another_app'), ('testapp2', '0001_initial'), ] }}} Thus, `AlterField` should pick this up. (Note for later: SQLite raised will required disabling constraint checking, ref #30023.) -- Ticket URL: <https://code.djangoproject.com/ticket/30691#comment:1> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
