How to Solve Error Message The view apps.views.index didn’t return an HttpResponse object. It returned None instead

As for the solution of the error message, actually it is already exist in ‘How to Change Default Page of a Django Application‘. It is by changing the content of the ‘views.py’ which exist in the ‘apps’ folder. Specifically, it is an application folder which is part of the Django project. So, the following is the revision of the ‘views.py’ file :

from django.shortcuts import render
# Create your views here.
def index(request):
    return render(request,"index.html")

The reason for the error appearance is because of the usage of the render method as in the above part. In order to render a specific content which in this context itis an HTML file of ‘index.html’, it need to use a return keyword. It means, it will return an object of HttpResponse from the ‘render’ method. Using only ‘render()’ method will cause the Django application to be considered as to return nothing at all. Although render() method has the output of HttpResponse object. But without the ‘return’ keyword’, the Django application will missunderstand it into no HttpResponse object returned.
