Django South schemamigration error AttributeError: 'Options' object has no attribute 'index_together' -


i working on django web app south db migration. quite new south, , django well. tried using south official tutorials, failed exception: attributeerror: 'options' object has no attribute 'index_together'. run south command this:

python manage.py schemamigration southtut --initial

the southtut models this: 

class knight(models.model):     name = models.charfield(max_length=100)     of_the_round_table = models.booleanfield()

my project models 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 got below:
