I am working on a Django web app with south for db migration. I am quite new to south, and django as well. I tried using south with the official tutorials, however it failed with an exception: AttributeError: 'Options' object has no attribute 'index_together'. I run the south command like this:
python manage.py schemamigration southtut --initial
The southtut models is this:
class Knight(models.Model):
name = models.CharField(max_length=100)
of_the_round_table = models.BooleanField()
My project models is this:
class Author(models.Model):
name = models.CharField(max_length=64)
authorId = models.CharField(max_length=32)
def __unicode__(self):
return self.name
class Meta:
db_table="Author"
class Video(models.Model):
videoId = models.CharField(max_length=32)
videoUrl = models.URLField(max_length=200)
author = models.ForeignKey(Author, null=True, related_name="videos", on_delete=models.SET_NULL)
class Meta:
db_table="Video"
class User(models.Model):
token = models.CharField(max_length=50, null=True)
favs = models.ManyToManyField(Video, related_name="fans", db_table="VideoUserR")
class Meta:
db_table = "User"
The whole error message I got is as below:
