I've got a model that looks something like this:
class HeiselFoo(models.Model):
title = models.CharField(max_length=250)
class Meta:
""" Meta """
app_label = "Foos"
db_table = u"medley_heiselfoo_heiselfoo"
And whenever I run my test suite, I get an error because Django isn't creating the tables for that model.
It appears to be an interaction between app_label and db_table -- as the test suite runs normally if db_table is set, but app_label isn't.
Here's a link to the full source code: http://github.com/cmheisel/heiselfoo
Here's the traceback from the test suite:

Ok, I'm a moron. You need to have an app in INSTALLED_APPS that matches your app_label or your tables won't get created.
You need to have an app in INSTALLED_APPS that matches your app_label or your tables won't get created.
In my case it doesn't work - when I change app name in INSTALLED_APPS on app_label wchich matches models Meta setting, but is different than app folder name, manage.py syncdb raise: "Error: No module named ...". I still have no idea how to sync models with database in case of using app_label and db_table in model Meta.
Caveat: this is not a direct answer to your question.
From looking at your code in github I find that you have defined the model inside models.py
. And yet you have defined app_label
inside your model's Meta
. Is there a reason for doing this?
Django's documentation says that app_label
is meant to be used
If a model exists outside of the standard
models.py
(for instance, if the app’s models are in submodules ofmyapp.models
), the model must define which app it is part of:
Given that, I don't see any reason to define an app_label
in your case. Hence my question. Perhaps you are better off without defining the app_label
after all.
