Django standalone apps with one app depending on another app - django.db.migrations.exceptions.NodeNotFoundError

I am using Django 4.0
I have written two standalone apps. Foo and FooBar.
Application Foo uses package django_nyt. Application FooBar uses functionality from application Foo.
I am able to makemigrations and migrate models in application Foo, however, when working with application FooBar, when I attempt to makemigrations, I get the following error trace:
Traceback (most recent call last):

Since these are standalone apps, I am using the design pattern advocated for in Django Standalone Reusable Libraries.

I have looked in the migrations folders for both applications and this is what I found:
foo app has the migration 0010_auto_20220802_2211 generated, and applied to django_nyt, to change the PK auto fields to use BigInteger.
foobar app does not have the migration file 0010_auto_20220802_2211 generated for django_nyt (hence the migration error). I can't for the life of me, work out why foobar is not using the migrations generated by foo, since it has a dependency on foo.
A no-brainer hack would be to simply copy over the missing migration file, but that is too fragile, and I want to actually understand what is going on, and why foobar is not using/applying the migrations created by a dependency.
This is what I have tried so far (did not resolve the issue):
I checked in the migration files for foo. Initially, I had kept them out of the repository
Created a dummy model class in foobar, that explicitly had a dependency on a model in dyango_nyt - the reasoning being that, if a django_nyt model existed in foobar, i would force migrations to be created for django_nyt.
This is what my dummy class in foobar/models.py looked like:
from django_nyt.models import Notification
class FooBarMigrationHack(Notification):
name = models.CharField(max_length=10)
None of the above has worked, and I'm still getting the same error stack trace as shown above, in my question.
How do I resolve this without having to manually copy the 'missing' migration file from foo/migrations/ to foobar/migrations/ ?

You've missed a comma. Very common typo:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.sites',
'cz',
'allauth',
'allauth.account' # no comma here
'allauth.socialaccount',
'allauth.socialaccount.providers.google',
]
So you want:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.sites',
'cz',
'allauth',
'allauth.account', # comma added
'allauth.socialaccount',
'allauth.socialaccount.providers.google',
]

you can specify which version of python your web app uses -3.7, 3.8. choose a python version that you have installed the package, be sure the same.
pip 3.8 install --user allauth
after that create a virtualenv and virtualenv's using the python version and then
pip install allauth

django.core.exceptions.ImproperlyConfigured: The included URLconf 'api.urls' does not appear to have any patterns in it

Having a hard time understanding why I am receiving this error. If I just leave the api/user/ path it works fine but when I try to add api/user/date_counter/ path I get this error. Using Django 3. Any help would be appreciated.

django.core.exceptions.ImproperlyConfigured: The included URLconf 'api.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

I think the problem is how you registering your ViewSet to urlpatterns. Try like this:
from rest_framework.routers import DefaultRouter
router = DefaultRouter()
router.register('date_counter', views.DateCounterViewSet)
urlpatterns = [
path('', include(router.urls)),
]
More information can be found in documentation.

Found the issue, the date_counter/views.py file was missing an import from django rest framework, from rest_framework import viewsets.

how can I avoid getting duplicates: account?

I am trying to install pip3 install django-allauth to prevent login before email confirmation, but at moment when setting up settings.py I get the following error. I don't want to rename all the project names, because it is going to affect the complete project. Is there a way to achieve this without too many changes?
