Views

Introduction#

A view function, or view for short, is simply a Python function that takes a Web request and returns a Web response. -Django Documentation-

[Introductory] Simple View (Hello World Equivalent)

Let’s create a very simple view to respond a “Hello World” template in html format.

To do that go to my_project/my_app/views.py (Here we are housing our view functions) and add the following view:

from django.http import HttpResponse

def hello_world(request):
    html = "<html><title>Hello World!</title><body>Hello World!</body></html>"
    return HttpResponse(html)

To call this view, we need to configure a url pattern in my_project/my_app/urls.py:

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^hello_world/$', views.hello_world, name='hello_world'),
]

Start the server: python manage.py runserver

Now if we hit https://localhost:8000/hello_world/, our template (the html string) will be rendered in our browser.
