I have an app where I create a simple table and then add a partial index
directly in SQL using RunSQL & migrations. I get an error with
`sqlmigrate` when I use it on a custom migration.
The command is : `manage.py sqlmigrate myapp 0002_custom.py`
0002_custom.py files looks like this:
{{{
class Migration(migrations.Migration):
dependencies = [
('myapp', '0001_initial'),
]
operations = [
migrations.RunSQL(
sql = 'CREATE UNIQUE INDEX test_idx ON book (name,
publisher_id) WHERE publisher_id IS NOT NULL;',
)
]
}}}
Here's the error:
{{{
