I hope this is just a case of "you doing it wrong". This issue has been a
thorn in my side for so long, and is an issue of constant confusion for
me. So like many larger projects, my applications doesnt have all the
django apps in the root folder. I created a framework as follows:
**project_root**
- **core** - contains essentials apps for the framework
- **applib** - contains apps that a certain deployment may or may not
use
- **dist** - contains apps that are only used for a certain
distribution
Now say there is app **foo** within **core**, then from experimentation
(as in things don't work otherwise) one must set:
{{{
# Filename: project_root/core/foo/apps.py
from django.apps import AppConfig
class FooConfig(AppConfig):
name = 'core.foo' # I hope here I am doing it wrong, and this is the
source of trouble
}}}
Okay great so the app name must include the dotted path from the project
root, no problem. So now all the **reverse(...)** and **{% url '...' %}**
use this dotted path app name.
Then say one has an issue of circular imports with models, so one must
lazy import the model name. However it does not use the app name, it uses
some other combination, after trying various ways turns out it must be in
like this:
{{{
# Filename: applib/bar/models.py
class BarModel(models.Model):
foo = models.ForeignKey('foo.FooModel', on_delete=models.PROTECT,
null=True, blank=True)
}}}
Notice how now the appname is '**foo**', whereas most of the time it is
'**core.foo**'.
Additionally with migrations it uses this shorter app name. If one looks
in the django_migration table and migration files, one sees '**foo**'
instead of '**core.foo**' (which is what it was explicitly set to).
Is this not a bit confusing?
