What are Django Views?

In this section, we will learn what are Views in Django and how to use views.py to display webpage onto the browser on a web request.

So in our previous section, we have successfully created our UserCreateForm form. Let's see what are Views in Django.

What are the Views?

A View function, or "view" for short, is simply a Python function that is written in views.py file, that takes a web request and returns a web response. This response can be the HTML contents of a Web page, or a redirect, or a 404 error, or an XML document, or an image, etc. So to display a webpage we require two things:

A URL associated with the view function
A Template (HTML page) which is to be displayed

Write your first view

Let's write the first view. Open the file account/views.py and put the following Python code in it:

from django.shortcuts import render, redirect
from django.views.generic.base import View
from django.contrib.auth import login, authenticate
from . import forms

# Create your views here.

#this is a class based view
class IndexView(View):

    def get(self, request, *args, **kwargs):

        return render(request, "registration/index.html")

#this is a function based view
def signup(request):
    if request.method == 'POST':
        form = forms.UserCreateForm(request.POST)
        if form.is_valid():

            form.save()
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, password=raw_password)
            login(request, user)

            return redirect('index')
    else:
        form = forms.UserCreateForm()
    return render(request, 'registration/signup.html', {'form': form})

That's it! we have written our first view. Next, we need to create a URL mapping for these functions and templates for each view function, so will see them in detail in our next tutorial.
