python - Django, South, and Guardian: Migrate -

i have 2 users, mh00h1 , mh00h2. have modela defines following in models.py:

class meta:     permissions = (         ('read','read'),         ('write','write'),     ) 

from shell, went set permissions:

>>>> frhde = create modela instance >>>> assign_perm('read', mh00h2, frhde)  doesnotexist: permission matching query not exist. lookup parameters {'codename': u'read', 'content_type': <contenttype: modela>} 

i realized south didn't migrate models after added class meta modela , confirmed this. changing read read2 shows south not detect change.

$ /manage.py schemamigration myapp --auto  running migrations myapp: - nothing migrate.  - loading initial data myapp. installed 0 object(s) 0 fixture(s) running migrations guardian: - nothing migrate.  - loading initial data guardian. installed 0 object(s) 0 fixture(s) 

how can schematicmigration correctly update database, or there better way not require redoing whole database?

thank you.

you can use ./manage.py syncdb --all, or create signal in this post.
