#22679 closed Bug (fixed)

makemigrations generates invalid code for default_permissions = ()

Description

This actually happens in Django 1.7b4.

When I define a Model with meta info like this:

class Foo(models.Model):
    # ...
    class Meta:
        default_permissions = ()

The ./manage.py makemigrations command generates a migration file like this:

options={
    # ...
    'default_permissions': (,),
}

...which causes SynaxError on migration.

Hi. I found something wrong in that commit:

# From tests/migrations/test_writer.py:134
        one_item_tuple = ('a')

This is wrong. It should be one_item_tuple = ('a',)
