Django templateview not recognizing my template

Currently I have in settings set my main directory to the templates folder so that I have a project level templates. Within that folder I have a home.html file.

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [BASE_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.contrib.messages.context_processors.messages',
        ],
    },
},

]

This is my views.py file

from django.views.generic import TemplateView

class HomePageView(TemplateView):
    template_name: "home.html"

Whenever I runserver I receive this error: ImproperlyConfigured at / TemplateResponseMixin requires either a definition of 'template_name' or an implementation of 'get_template_names()'

I'm following a book to the T (Django for Beginners) and i'm unsure why this error could be happening. Has the syntax for template_name changed? I've checked all the documentations and my name seems to be okay. I've also tried to input the pathname to the file instead.

Any help would be wonderful.

Thank you

You are making an annotation: you should use an equals sign = instead of a colon ::

from django.views.generic import TemplateView


class HomePageView(TemplateView):
    template_name = 'home.html'

Normally templates are also "namespaced" by putting these into a directory with the name of the app, so:

from django.views.generic import TemplateView


class HomePageView(TemplateView):
    template_name = 'app_name/home.html'

and thus put the template in the directory of the app_name/templates/app_name/home.html. This prevents that you later would collide with a template with the same name in a different app.

You have used the view incorrectly. Replace the : with = and it should be fine.
