CookBook - Data Models - Splitting models across multiple files
To split models across multiple files, you can do the following (works at least with revision 2819).
The important thing to notice here is the db_table
and app_label
attributes in the Meta
class. If those are omitted, a subsequent manage.py syncdb
run will not pick up these models.
NOTE: When #3591 gets applied you won't need the Meta
class anymore, so if this link: #3591 has a strike-through and you are running svn, you don't need the Meta
class.
This has been verified to work without the Meta class db_table, in the current main branch.

:
from poll import Poll from choice import Choice
apps/polls/models/poll.py
:
from django.db import models class Poll(models.Model): question = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') class Meta: db_table = 'poll' app_label= 'polls'
apps/polls/models/choice.py
:
from django.db import models class Choice(models.Model): poll = models.ForeignKey('Poll') choice = models.CharField(max_length=200) votes = models.IntegerField() class Meta: db_table = 'choice' app_label = 'polls'
Providing initial sql data for models
If you provide initial sql data for you models (as described in Providing initial SQL data) you should notice that at least in Django 0.95 the path for sql files is different when this recipe is applied. In this case the path is:
<appname>/models/sql/<modelname>.sql
