Django project problems with admin panel

Question

I'm storing all my models in one folder called models, it's working fine for me. But there is some problems with admin.py, where should I store this file? Within models folder or within app folder? When i'n trying to insert models into admin panel i got an error.

Error:

It's better within app folder – catherine Mar 16 '13 at 08:33 — catherine, Mar 16 '13 at 08:33

It's perfectly fine to separate objects into modules into packages etc. You just have to remember that Django only looks for an admin.py and models.py file in a package's root by default. The solution here is to explicitly import the required files, a good place to do this in is __init__ files which are compiled first.

so e.g. (Django 1.4 setup, more info on Django structures here):

/project_root
    /project
        __init__.py
        settings.py
        urls.py
    /app
        __init__.py
        admin.py
        models.py
    manage.py

can be converted to:

/project_root
    /project
        __init__.py
        settings.py
        urls.py
    /app
        __init__.py  # <- import statements
        /admin
            admin_foo.py
            admin_bar.py
        /models
            model_foo.py
            model_bar.py
    manage.py

Then in your __init__.py inside your app folder add:

from .models.model_foo import Foo
from .models.model_bar import Bar
from .admin.admin_foo import FooAdmin
from .admin.admin_bar import BarAdmin

And because of how installed apps defines things, you should not forget to add the app_label attribute to the model Meta class:

class Foo(models.Model):
    # fields...
    class Meta:
        app_label = 'app'


class Bar(models.Model):
    # fields...
    class Meta:
        app_label = 'app'

I did such thing but models not showing up in admin panel... — vovaminiof, Mar 16 '13 at 09:15
Probably because there's still some old compiled hidden `.pyc` files in your app folder, delete them and you should be fine. `find . -type f -name "*.pyc" | xargs rm;` — Hedde van der Heide, Mar 16 '13 at 09:22
that sounds like a completely different issue, but you could add the stacktrace to your post to make sure — Hedde van der Heide, Mar 16 '13 at 09:35
