Hi Guys,

When I try to migrate my models to redshit I got this error: 'DatabaseSchemaEditor' object has no attribute 'sql_create_table_unique'

I'm using : Django 1.10, python 2.7 and django-redshift-backend 0.5

All trace : Operations to perform: Apply all migrations: admin, auth, authtoken, contenttypes, dashboard, sessions Running migrations: Rendering model states...

Has it happened to someone else?

Thank you fellows

I removed admin and auth from settings.INSTALLED_APPS as I was not using them. The migrations in there modify a non-null column, and the "create-update-drop-rename" method for migrations doesn't work for that.

I've been trying to setup a new table in redshift and I'm facing the same issue.

Definitely it's a bug of django-redshift-backend. Django-1.9 remove sql_create_table_unique attribute.

django-redshift-backend still supports django-1.8, so I have to if/else statement around there. I will fix this.

[shimizukawa]

fixed. It will be released around next weekend.
