ValueError: The given username must be set. Error Occured Using Django for registering User

raise ValueError('The given username must be set') using django python ... I have been trying to register a user using from django.contrib.auth.models import user

Views.py

from django.shortcuts import render, redirect
from django.http import HttpResponse
from django.contrib.auth.models import User

# Create your views here.

def register(request):

    if request.method == 'POST':
        username = request.POST.get('username')
        email = request.POST.get('email')
        password1 = request.POST.get('password1')
        password2 = request.POST.get('password2')

        if password1 == password2:
            if User.objects.filter(username = username).exists():
                return redirect('register')
            elif User.objects.filter(email = email).exists():
                return redirect('register')
            else:
                user=User.objects.create_user(username = username,password =password1, email = email)
                user.save()
                return redirect('login')
        else:
            return redirect('/')

    else:
        return render(request, 'register.html')

def login(request):
    return render(request, 'login.html')

user=User.objects.create_superuser(username = username,password =password1, email = email) I want to know that why it is just sending that The given username is must be set but instead I have set super_user already. How to resolve this? It is not getting the username by POST method or is there any other mistake which I am ignoring?

add name attribute in your input tags, something like this:

...
<input type="text" class="form-control" id="username" name="username">
...
<input type="password" class="form-control" id="password1" name="password1">
...
<input type="password" class="form-control" id="password2" name="password2">
...
<input type="email" class="form-control" id="email" name="email" placeholder="name@example.com">
...
