= CookBook - [wiki:CookBookDataModels 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.

{{{apps/polls/models/__init__.py}}}:
{{{
#!python
from poll import Poll
from choice import Choice
}}}

{{{apps/polls/models/poll.py}}}:
{{{
#!python
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}}}:
{{{
#!python
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 [http://www.djangoproject.com/documentation/model_api/#providing-initial-sql-data 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}}}
