A view is a place where we put our business logic of the application. The view is a python function which is used to perform some business logic and return a response to the user. This response can be the HTML contents of a Web page, or a redirect, or a 404 error.
All the view function are created inside the views.py file of the Django app.
Django View Simple Example
//views.py
import datetime
# Create your views here.
from django.http import HttpResponse
def index(request):
now = datetime.datetime.now()
html = "<html><body><h3>Now time is %s.</h3></body></html>" % now
return HttpResponse(html) # rendering the template in HttpResponse First, we will import DateTime library that provides a method to get current date and time and HttpResponse class.
Next, we define a view function index that takes HTTP request and respond back.
View calls when gets mapped with URL in urls.py. For example
path('index/', views.index), Django View Example
// views.py
from django.shortcuts import render
# Create your views here.
from django.http import HttpResponse, HttpResponseNotFound
def index(request):
a = 1
if a:
return HttpResponseNotFound('<h1>Page not found</h1>')
else:
return HttpResponse('<h1>Page was found</h1>') # rendering the template in HttpResponse This method will execute only if the request is an HTTP GET request.
//urls.py
from django.contrib import admin
from django.urls import path
from myapp import views
urlpatterns = [
path('admin/', admin.site.urls),
path('index/', views.index),
path('show/', views.show),
]
