Django provides several class based generic views to accomplish common tasks. The simplest among them is TemplateView. It Renders a given template, with the context containing parameters captured in the URL.
TemplateView should be used when you want to present some information on an HTML page. TemplateView shouldn’t be used when your page has forms and does creation or update of objects. In such cases, FormView, CreateView, or UpdateView is a better option.
TemplateView is most suitable in the following cases:
- Showing ‘about us’ like pages that are static and hardly need any context. Though, it is easy to use context variables with TemplateView.
- Showing pages that work with GET requests and don’t have forms in them.
Explanation :
Illustration of How to use TemplateView using an Example. Consider a project named geeksforgeeks having an app named geeks.

Let’s write a view using base class view View and then modify it to use TemplateView. TemplateView would help us avoid several lines of code.
- Enter the following code into views.py file of geeks app.
Python3
from django.views.generic.base import View
from django.shortcuts import render
class AboutUs(View):
def get(self, request, *args, **kwargs):
return render(request, "aboutus.html")
|
- Create a folder named templates inside the geeks app and then create a file named aboutus.html inside templates folder.
- Enter the following code into aboutus.html file.
HTML
<!DOCTYPE html>
<html>
<head>
<title>AboutUs</title>
</head>
<body>
<h2>Welcome To GFG</h2>
</body>
</html>
|
- Enter the Following code into urls.py of geeksforgeeks project folder.
Python3
from django.contrib import admin
from django.urls import path
from geeks.views import AboutUs
urlpatterns = [
path('admin/', admin.site.urls),
path('',AboutUs.as_view(),name="aboutus")
]
|
- Run below three commands to see the output.
Python manage.py makemigrations
Python manage.py migrate
Python manage.py runserver
- Same output can be achieved using TemplateView , replace code of views.py file of geeks app by given below code.
Python3
from django.views.generic.base import TemplateView
class AboutUs(TemplateView):
template_name = 'aboutus.html'
|
Let’s check what is there on http://localhost:8000/
