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:
{{{
