Django Views
Views
Django views are Python functions that takes http requests and returns http response, like HTML documents.
A web page that uses Django is full of views with different tasks and missions.
Views are usually put in a file called views.py
located on your app's folder.
There is a views.py
in your
members
folder that looks like this:
members/views.py
:
from django.shortcuts import render
# Create your views here.
Find it and open it, and replace the content with this:
members/views.py
:
from django.shortcuts import render
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello world!")
This is a simple example on how to send a response back to the browser.
But how can we execute the view? Well, we must call the view via a URL.
URLs
Create a file named urls.py
in the same folder as the
views.py
file, and type this code in it:
members/urls.py
:
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
]
The urls.py
file you just created is
specific for the members
application. We have
to do some routing in the root directory myworld
as well. This may seem complicated, but for now, just follow the instructions
below.
There is a file called
urls.py
on the
myworld
folder, open that file and add the
include
module in the
import
statement, and also add a
path()
function in the
urlpatterns[]
list, with arguments that will route users that comes in via
127.0.0.1:8000/members/
.
Then your file will look like this:
myworld/urls.py
:
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('members/', include('members.urls')),
path('admin/', admin.site.urls),
]
If the server is not running, navigate to the /myworld
folder and execute this command in the command prompt:
py manage.py runserver
In the browser window, type 127.0.0.1:8000/members/
in the address bar.
