python - Django: ProgrammingError when dealing with ManyToMany database -



python - Django: ProgrammingError when dealing with ManyToMany database -

started using manytomany relationships in postgresql database, end

"programming error : relation "sequences_sequence_access" not exist"

can please explain me fault?

models

from django.db import models django.contrib.auth.models import user class sequence(models.model): name = models.charfield(max_length=200) seq = models.textfield() access = models.manytomanyfield(user) def __unicode__(self): homecoming self.name

views

x = sequence(name=minput[0:mindex]) x.seq = alncontent x.save() x.access.add(user.objects.get(username=musername)) #problems start here x.save()

note: did syncdb (but after doing incorrectly once, , field still there , can't remove it)

you have utilize migration here. can utilize south(for django<=1.6). btw documentation:

migrations django’s way of propagating changes create models (adding field, deleting model, etc.) database schema. they’re designed automatic, you’ll need know when create migrations, when run them, , mutual problems might run into.

python database django postgresql many-to-many
