Render a HTML Template as Response – Django Views

11 Nov, 2019
A view function, or view for short, is simply a Python function that takes a Web request and returns a Web response. This article revolves around how to render an HTML page from Django using views. Django has always been known for its app structure and ability to manage applications easily. Let’s dive in to see how to render a template file through a Django view.
Illustration of How to render a HTML Template in a view using an Example. Consider a project named geeksforgeeks having an app named geeks.
Refer to the following articles to check how to create a project and an app in Django.

After you have a project and an app, open views.py and let’s start creating a view called geeks_view which is used print “Hello world” through a template file. A django view is a python function which accept an argument called request and returns an response.Enter following code into views.py of app
from django.shortcuts import render  # Create your views here.def geeks_view(request):          # render function takes argument  - request    # and return HTML as response    return render(request, "home.html")
but this code won’t work until into define a proper mapping of URL. Mapping means you need to tell Django what a user enters in the browser to render your particular view. For example www.geeksforgeeks.org tells django to execute its home page view. So let’s modify urls.py to start our view.Include your app’s urls into main urls by adding following code to geeksforgeeks > urls.py
"""geeksforgeeks URL Configuration  The `urlpatterns` list routes URLs to views. For more information please see:    https://docs.djangoproject.com / en / 2.2 / topics / http / urls / Examples:Function views    1. Add an import:  from my_app import views    2. Add a URL to urlpatterns:  path('', views.home, name ='home')Class-based views    1. Add an import:  from other_app.views import Home    2. Add a URL to urlpatterns:  path('', Home.as_view(), name ='home')Including another URLconf    1. Import the include() function: from django.urls import include, path    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))"""from django.contrib import adminfrom django.urls import path, include  urlpatterns = [    path('admin/', admin.site.urls),    path('', include("geeks.urls")),]
Now lets create a path to our view from geeks > urls.py
from django.contrib import adminfrom django.urls import path  # importing views from views..pyfrom .views import geeks_view  urlpatterns = [    path('', geeks_view ),]
Done. Now go to check if our template gets rendered or not. visit here – http://localhost:8000/
It is giving an error that you don’t have a template home.html. So let’s create our template now, in geeks folder create a folder called templates and create a file home.html into it. Now let’s check again – http://localhost:8000/.
This way you can render any template file using the same procedure –
1. Create a view in views.py
2. Create a template file which is to be rendered and link it to the view.
3. Create a URL to map to that view.
