Re: Using multiple model files per app with the Improved Multiple Model Files Django Snippet

Awesome, thanks, I love python but I am not (yet) skilled at the art of incantation.

The snippet above: http://djangosnippets.org/snippets/1838/

did have some incantation but the post was fairly old in terms of django/python's history.

I can't tell one incantation from another but I can tell a django app that fails to sync from one that does.

If anybody has trouble with this kind of django project structure,

Mike's incantation works just right, I don't want to be as bold as to say the one in the snippet

doesn't work, but I couldn't get it to work.

if its not already clear heres my set up:

#my_project

#    manage.py
#    settings.py

#    myapp/

#        models/  #            __init__.py  #            models1.py  #            models2.py

------------------------------------------------------
in __init__.py:

    # incantation 

    from __future__ import absolute_import 

    from .models1 import ModelOne 
    from .models2 import ModelTwo

------------------------------------------------------

in models1.py:

from myapp.models import Model2
------------------------------------------------------

in models2.py:

from myapp.models import Model1

------------------------------------------------------

in admin.py:

from my_app.models import Model1, Model2

I also took a precaution that I'm not sure was required:

I made sure Django knew which app to put all my Model1 & Model2 in

by defining a Meta property like this:

class Meta:

        app_label = 'myapp'

I'm trying to use multiple files for my models in a single app.

I found a nice solution on Django Snippets:

http://djangosnippets.org/snippets/1838/

but I'm not able to get it to work.

The docs assume that I know more than I do about how this solution works.

Its involves using a models folder for the app like this:

# myapp/  #   models/  #     __init__.py  #     models1.py  #     models2.py

and then including an __init__.py file in the folder to make it a package

this file also contains this code:

import django.db.models          import sys                         appname = "myapp"  from models1 import *  from models2 import *    __all__ = []                       for decl in globals().values():     try:      if decl.__module__.startswith(__name__) and issubclass(decl, django.db.models.Model):        decl._meta.db_table = decl._meta.db_table.replace('models', appname)        decl._meta.app_label = appname           __all__.append(decl.__name__)        django.db.models.loading.register_models(appname, decl)    except:      pass  
I don't understand this code, but hopefully I don't have to.

I just want to be able to import my individual model modules:

models1.py & models2.py
from my views and admin.py
the import statements are not included in the snippet
and I've tried what seems reasonable and keep getting errors importing the modules saying they don't exist
I would expect you do something like
import myapp.models.model1
&
import myapp.models.model2
but this doesn't work.
maybe I don't understand the magic in the __init__.py file
or I'm just being plain stupid.
Can someone point me toward getting this solution working with my imports?
