Django: User not authenticating correctly - django

Question

When logging into my app, the user is not authenticating correctly.
Views.py
'''
from django.shortcuts import render, redirect, get_object_or_404
from django.contrib.auth import authenticate, login
from django.urls import reverse
from users.forms import CustomUserCreationForm
from django.http import HttpResponse
from users.models import Blog
from django.contrib.auth.decorators import user_passes_test
from django.contrib.auth.decorators import login_required
# Create your views here.
def intro(request):
return render(request, "intro.html")
def logmein(request):
return render(request, "logmein.html")
def login(request):
username1 = request.POST.get('username')
password1 = request.POST.get('password')
user = authenticate(request, username=username1, password=password1)
login(user, request)
if user.is_authenticated:
return render(request, "users/mainmenu.html")
else:
return render(request, "intro.html")
def mainmenu(request):
return render(request, "users/mainmenu.html")
'''
Mainmenu.html
'''
{% extends 'base.html' %}
{% block content %}
<h2>MainMenu</h2>
Hello, {{ user.username }}
{% endblock %}
'''
When mainmenu.html is displayed following login, the user.username is showing as the SuperUser, regardless
of what username and password is used to login.

try this:
from django.contrib.auth import login as auth_login
def login(request):
username1 = request.POST.get('username')
password1 = request.POST.get('password')
user = authenticate(username=username, password=password)
if not user: # authentication fails
messages.error(request, 'error')
return render(request, "intro.html")
# login success
auth_login(request, user)
messages.success(request, 'success')
return render(request, "users/mainmenu.html")
