I've been trying to fork django-oscar customer app. I've followed the guidelines on their documentation, but I can not apply migrations due to a ValueError: Related model 'customer.user' cannot be resolved. My project directory looks like this: project ├── config │ ├── asgi.py │ ├── __init__.py │ ├── settings.py │ ├── urls.py │ └── wsgi.py ├── customer │ ├── apps.py │ ├── __init__.py │ ├── migrations │ │ ├── 0001_initial.py │ │ ├── 0002_auto_20150807_1725.py │ │ ├── 0003_update_email_length.py │ │ ├── 0004_email_save.py │ │ ├── 0005_auto_20181115_1953.py │ │ ├── 0006_auto_20190430_1736.py │ │ ├── 0007_auto_20200801_0817.py │ │ ├── 0008_alter_productalert_id.py │ │ ├── 0009_user.py │ │ ├── __init__.py │ ├── models.py ├── manage.py Here are the steps I followed to arrive at the point I am now: ./manage.py oscar_fork_app customer . I added the customer app to my list of INSTALLED_APPS DJANGO_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "django.contrib.sites", "django.contrib.flatpages", ] PROJECT_APPS = [ "customer", # "customer.apps.CustomerConfig",, ] OSCAR_APPS = [ "oscar.config.Shop", "oscar.apps.analytics.apps.AnalyticsConfig", "oscar.apps.checkout.apps.CheckoutConfig", "oscar.apps.address.apps.AddressConfig", "oscar.apps.shipping.apps.ShippingConfig", "oscar.apps.catalogue.apps.CatalogueConfig", "oscar.apps.catalogue.reviews.apps.CatalogueReviewsConfig", "oscar.apps.communication.apps.CommunicationConfig", "oscar.apps.partner.apps.PartnerConfig", "oscar.apps.basket.apps.BasketConfig", "oscar.apps.payment.apps.PaymentConfig", "oscar.apps.offer.apps.OfferConfig", "oscar.apps.order.apps.OrderConfig", # "oscar.apps.customer.apps.CustomerConfig", "oscar.apps.search.apps.SearchConfig", "oscar.apps.voucher.apps.VoucherConfig", "oscar.apps.wishlists.apps.WishlistsConfig", "oscar.apps.dashboard.apps.DashboardConfig", "oscar.apps.dashboard.reports.apps.ReportsDashboardConfig", "oscar.apps.dashboard.users.apps.UsersDashboardConfig", "oscar.apps.dashboard.orders.apps.OrdersDashboardConfig", "oscar.apps.dashboard.catalogue.apps.CatalogueDashboardConfig", "oscar.apps.dashboard.offers.apps.OffersDashboardConfig", "oscar.apps.dashboard.partners.apps.PartnersDashboardConfig", "oscar.apps.dashboard.pages.apps.PagesDashboardConfig", "oscar.apps.dashboard.ranges.apps.RangesDashboardConfig", "oscar.apps.dashboard.reviews.apps.ReviewsDashboardConfig", "oscar.apps.dashboard.vouchers.apps.VouchersDashboardConfig", "oscar.apps.dashboard.communications.apps.CommunicationsDashboardConfig", "oscar.apps.dashboard.shipping.apps.ShippingDashboardConfig", ] INSTALLED_APPS = DJANGO_APPS + PROJECT_APPS + OSCAR_APPS As you can see I tried the "oscar" way of addind the app by specifying the path to the CustomerConfig method they generate with their command but it did not help, so I tried the regular "django" way and it did not work either. And then I added my new model to the AUTH_USER_MODEL settings keys like this: AUTH_USER_MODEL = "customer.User" When I try to make migrations, it works as intended, and creates the migration number 9 in the list you can see above, but when I try to apply the migrations, I get this error: ./manage.py migrate Operations to perform: Apply all migrations: address, admin, analytics, auth, basket, catalogue, communication, contenttypes, customer, flatpages, offer, order, partner, payment, reviews, sessions, shipping, sites, thumbnail, voucher, wishlists Running migrations: Applying contenttypes.0001_initial...
