Trying to add new app but templates are a mess

[ronaldgreeff]

I've created a new app and added it to the project folder. Weirdly, generic views (ListView) expect templates to be in a different folder than normal views (View).

- requirements
- my_project
    - contrib
    ▒   - sites
    ▒       - migrations
    - static
    ▒   - css
    ▒   - fonts
    ▒   - images
    ▒   ▒   - favicons
    ▒   - js
    - templates
    ▒   - account
    ▒   - pages
    ▒   - my_app
    ▒           - item_list.html <- only works here (generic / ListView)
    ▒   - users
    - my_app
    ▒   - migrations
    ▒   - templates
    ▒           - item_detail.html <- only works here (View)
    - users
    ▒   - migrations
    ▒   - tests
    - utils

My settings:

ROOT_DIR = Path(__file__).resolve(strict=True).parent.parent.parent
APPS_DIR = ROOT_DIR / "my_project"

INSTALLED_APPS = [
    ...
    "my_project.users",
    "my_project.my_app",  #  also tried my_project.my_app.apps.MyAppConfig
    ...
]

TEMPLATES = [
    {
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        "DIRS": [str(APPS_DIR / "templates")],
        "APP_DIRS": True,
        "OPTIONS": {
            "context_processors": [
                "django.template.context_processors.debug",
                "django.template.context_processors.request",
                "django.contrib.auth.context_processors.auth",
                "django.template.context_processors.i18n",
                "django.template.context_processors.media",
                "django.template.context_processors.static",
                "django.template.context_processors.tz",
                "django.contrib.messages.context_processors.messages",
                "my_project.users.context_processors.allauth_settings",
            ],
        },
    }
]

my_project/my_app/apps.py

from django.apps import AppConfig
from django.utils.translation import gettext_lazy as _


class MyAppConfig(AppConfig):
    # default_auto_field = "django.db.models.BigAutoField"
    name = "my_project.my_app"
    verbose_name = _("My_App") # not really this but you get it

    def ready(self):
        try:
            import my_project.my_app.signals  # noqa F401
        except ImportError:
            pass

Am I missing something?

I will try to answer the 3 questions that were asked:

1 - How to create a new django app to cookiecuter-django based project:

1 - create the <name-of-the-app> app with python manage.py startapp
2 - move <name-of-the-app> directory to <project_slug> directory
3 - edit <project_slug>/<name-of-the-app>/apps.py and
change name = "<name-of-the-app>" to name = "<project_slug>.<name-of-the-app>"
4 - add "<project_slug>.<name-of-the-app>.apps.<NameOfTheAppConfigClass>", on your LOCAL_APPS on config/settings/base.py

2 - How to explicitly customize the template used by django views that inherit from TemplateResponseMixin:

For the ListView/DetailView problem, it would probably be nice if you had it explicit and simply set template_name:

- requirements
- my_project
    - contrib
    ▒   - sites
    ▒       - migrations
    - static
    ▒   - css
    ▒   - fonts
    ▒   - images
    ▒   ▒   - favicons
    ▒   - js
    - templates
    ▒   - account
    ▒   - pages
    ▒   - my_app
    ▒           - item_list.html <- only works here (generic / ListView)
    ▒           - item_detail.html
    ▒   - users
    - my_app
    ▒   - migrations
    - users
    ▒   - migrations
    ▒   - tests
    - utils

from django.views import generic
from my_project.my_app.models import MyModel


class MyModelBaseViewMixin:
    model = MyModel

class MyModelListView(MyModelBaseViewMixin, generic.ListView):
    template_name = 'my_app/item_list.html'

class MyModelDetailView(MyModelBaseViewMixin, generic.DetailView):
    template_name = 'my_app/item_detail.html'

3 - How to customize the template used by django admin views

if the problem is related to Django Admin integration, please customize the path to the correct template via the Custom template options of Django Admin: https://docs.djangoproject.com/en/4.0/ref/contrib/admin/#custom-template-options
