#26461: django.db.utils.ProgrammingError: relation "..." does not exist ----------------------------+------------------------------------ Reporter: prokaktus | Owner: nobody Type: Bug | Status: new Component: Migrations | Version: 1.9 Severity: Normal | Keywords: postgresql, migrations Triage Stage: Unreviewed | Has patch: 0 Easy pickings: 0 | UI/UX: 0 ----------------------------+------------------------------------ Hi!
{{{ psql (PostgreSQL) 9.4.5 Django==1.9.5 psycopg2==2.6.1 python2.7/python3.4 }}} Exception occurs while running one-file migration with `AddField` and `RenameModel`. If I split the file into different files, all migrations passing ok. With `sqlite3`-engine issue is not reproduced, because of that I think that it can be `postgres`-specific problem. Minimal example of my migration file: {{{ from __future__ import unicode_literals from django.db import migrations, models class Migration(migrations.Migration): initial = True dependencies = [ ] operations = [ migrations.CreateModel( name='Mymodel', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ], ), migrations.AddField( model_name='mymodel', name='name', field=models.SlugField(max_length=100, null=True), ), migrations.RenameModel( # <- error here old_name='Mymodel', new_name='NewModel', ), ] }}} As I said above, If I split files into two or remove `AddField` or `RenameModel` -- exception is gone. Problem not reproduced with `CharField`, but reproduced with `ForeignKey`. models.py: {{{ from django.db import models class NewModel(models.Model): name = models.SlugField(max_length=100, null=True) }}} And lastly exception stacktrace: {{{ ./manage.py migrate base 0001 Operations to perform: Target specific migration: 0001_initial, from base Running migrations: Rendering model states...
