Comment (by Henrique Chehad):
Thanks.
The older migration file (0001_initial) that contains `artist` field was
with bytestring. I edited it and now the `migrate` worked. It was
affecting the current migration file (0005).
{{{
- ('artist', models.ForeignKey(db_column=b'actor_id',
on_delete=django.db.models.deletion.CASCADE, to='artists.Artist')),
+ ('artist', models.ForeignKey(db_column='actor_id',
on_delete=django.db.models.deletion.CASCADE, to='artists.Artist')),
}}}
Would be good a contribution with clearer error message or converting it
before the `quote_name` function?
Replying to [comment:1 Tim Graham]:
> Did you follow the advice about
[https://docs.djangoproject.com/en/1.10/topics/migrations/#supporting-
python-2-and-3 supporting Python 2 and 3]? It looks like you might have a
field in a migration that uses a bytestring (i.e. `b'artist'`). The issue
is likely obsolete with the removal of Django's support for Python 2, but
if you can reproduce some problem using only Python 3, please be more
specific about the steps and provide a sample project. Thanks!
