#27338: Running an AlterField to change a CharField primary key to AutoField crashes ------------------------------------------------+------------------------ Reporter: Tim Graham | Owner: nobody Type: Cleanup/optimization | Status: new Component: Migrations | Version: master Severity: Normal | Keywords: Triage Stage: Accepted | Has patch: 0 Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | ------------------------------------------------+------------------------ For example: change `id = models.CharField(max_length=20, primary_key=True)` to `id = models.AutoField(primary_key=True)`. It generates this operation: {{{ migrations.AlterField( model_name='foo', name='id', field=models.AutoField(primary_key=True, serialize=False), ), }}} Running it on PostgreSQ gives: `django.db.utils.ProgrammingError: operator class "varchar_pattern_ops" does not accept data type integer`. I'm not sure if this can be made to work sensibly. Is it possible to autopopulate the `AutoField`? I ran into this situation while investigating #27267.
