Django template language how to fix-CodePudding

Hi I'm trying to build a simple django app but I can't get index.html file to recognise the variables created in views.py. Nothing I do seems to work. Does it have to be configured somehow in settings.py perhaps?

index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    <p>Hello world {{ name }}</p>
</body>
</html>

views.py:

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def index(request):
    context = {'name' : 'Peter'}
    return render(request, 'index.html', context)

urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index, name='index')
]

Whatever I try, the browser just doesn't recognise anything in the {{}}. It just leaves it blank. I seem to have tried everything. Please help, I'm tearing my hair out.

Here's the github repo if anyone cares to look at it:

In your 'stacqato/settings.py' file I see that you have not added your app to the list of installed apps. You should add 'stack.apps.StackConfig' to INSTALLED_APPS in 'stacqato/settings.py'

In your settings.py file, in the TEMPLATES-section, APP_DIRS is true, so you should create a directory 'stack' under your 'templates' directory and move the 'index.html' file to the 'templates/stack' directory.

I mostly use class based views, so in your views.py that would become something like:

class IndexView(generic.View):
    template_name = 'stack/index.html'
    context = {'name': 'Peter'}

    def get(self, request, *args, **kwargs):
        return render(request, self.template_name, context)

In your urls.py that translates to:

path('', views.IndexView.as_view(), name='index'),

I took a look at your Github repo. You didn't mention stack app in installed apps

I think you're missing a slash before index.html in your render statement. Try this:

return render(request, '/index.html', context)
