My apps look like this: DJANGO_APPS = [ "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.sites", "django.contrib.messages", "django.contrib.staticfiles",

"django.contrib.humanize", # Handy template tags

"django.contrib.admin",
"django.forms",

]

THIRD_PARTY_APPS = [ "crispy_forms", "allauth", "allauth.account", "allauth.socialaccount", ]

LOCAL_APPS = [ "elimubora.users.apps.UsersConfig", "elimubora.shop.apps.ShopConfig", "elimubora.cart.apps.CartConfig", "elimubora.orders.apps.OrdersConfig",

Your stuff: custom apps go here

]

What should've happened instead?

@luzfcb I have done that but the error still persists. apps.py:

from django.apps import AppConfig

class ShopConfig(AppConfig):
    name = 'elimubora.shop'

urls.py:

from django.urls import path
from . import views

app_name='shop'

urlpatterns = [
    path(
    route='',
    view=views.book_list,
    name='book_list'
    ),
    path(route='<slug:category_slug>/',
    view=views.book_list,
    name='book_list_by_category'
    ),
    path(route='<int:id>/<slug:slug>/',
    view=views.book_detail,
    name='book_detail'),
]

I have the app in the project-slug:

(env) (base) reus@reus:~/Documents/WORK/elimubora$ ls elimubora/
cart         contrib      media   __pycache__  static     users
conftest.py  __init__.py  orders  shop         templates  utils
