Here above I'm trying to implement authentications on my current app. I want to show login failure error on same login page, For which I have written a 'AuthenticationForm' class above.
I read some docs but don't know exactly how to use this form in my views for Authentication purpose.
Please! Can anybody suggest me how to make it correct

I think that you didn't declare your model correctly:
class UserEditView(generic.UpdateView):
# models = UserChangeForm #That has no sense.
model = User #The name of your model (Probably the default one: User).
form_class = UserChangeForm
template_name = 'vendor/edit_profile.html'
success_url = reverse_lazy('vendor_admin')
def get_object(self):
return self.request.user
Other thing. You have declared your template name twice. According to your views.py you can delete the template_name on your urls.py:
path('edit_profile/', UserEditView.as_view(), name='edit_profile'),
Before extending the user module, I was easily able to register new users and the page would get redirected to the login page. Now on registering new users, the profile is not getting created and the page is also not getting redirected. The new user does get created though and sometimes the error is object does not exist, user profile does not exist, and sometimes the error is forbidden, csrf verification failed. I dont know where I'm going wrong. existing users are able to login and update profiles but new users I'm having a problem with.
Models.py is:
from django.db import models
from django.contrib.auth.models import User
class Profile(models.Model):
user = models.OneToOneField(User,null= True ,on_delete= models.CASCADE)
profile_pic = models.ImageField(null = True, blank= True)
first = models.CharField(max_length=500, null=True)
last = models.CharField(max_length=500, null=True)
email = models.CharField(max_length=500, null=True)
mobile_number = models.IntegerField(null=True)
location = models.CharField(max_length= 500, null= True)
postal = models.IntegerField(null=True)
def __str__(self):

I've tried everything as of now, but i don't understand the mistake. Can someone please guide me through cause at this moment i'm frustrated, on the verge of crying and don't understand what to do.
There are basically two problems here:
there is a view Profile, and thus this will override the reference to the Profile model; and
you do not create a model record with Model.object.create(), but with Model.objects.create().
I would advise that you rename your views in snake_case, and remove the wildcard import, this is often not a good idea:
from django.shortcuts import render, redirect
from django.contrib.auth.forms import UserCreationForm
from .forms import CreateUserForm, ProfileForm
from django.http import HttpResponse, HttpResponseRedirect
from django.contrib import messages
from django.contrib.auth import login, authenticate, logout
from django.contrib.auth.decorators import login_required
from .models import Profile
def register_page(request):
if request.user.is_authenticated:
return redirect('Profile')
else:
if request.method == 'POST':
form = CreateUserForm(request.POST)
if form.is_valid():
user = form.save()
Profile.objects.create(
user = user,
)
messages.success(request, 'Account created for {user.first_name}')
return HttpResponseRedirect('/Login/')
else:
form = CreateUserForm()
context = {'form': form }
return render(request, 'register.html', context)
#login_required(login_url='Login')
def profile(request):
profile = request.user.profile
form = ProfileForm(instance=profile)
if request.method == 'POST':
form = ProfileForm(request.POST, request.FILES, instance=profile)
if form.is_valid():
form.save()
context = {'form': form}
return render(request, 'profile.html', context)
You will also need to update the urls.py to work with the renamed views.
I'm really new to Django and I want to teach myself my making a simple note. But I don't understand how django forms work. I made simple template when I can display the user's notes and now I am trying to make a view when the user can add new notes to account using a simple form.
Here is my views.py file

# Create your views here.
def loginPage(request):
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return redirect('home')
else:
messages.info(request, 'Username or pasword is incorrect')
context = {}
return render(request, 'accounts/login.html', context)
def registerPage(request):
form = CreateUserForm()
if request.method == 'POST':
form = CreateUserForm(request.POST)
if form.is_valid():
form.save()
user = form.cleaned_data.get('username')
messages.success(request, 'Account was created for '+ user)
return redirect('home')
context = {'form': form}
return render(request, 'accounts/register.html', context)
def logoutUser(request):
logout(request)
return redirect('login')
#login_required(login_url='login')

The problem is the new note isn't added when I submit the data. And also if anyone have other suggestions for structuring my views or making this app better I am happy to read them and learn new ways of improving my project. Sorry for long post. I am really noob.
I have a django project called log and an application called basic_app. I created a register form but when I want to create a user_login, I get this error:

I am trying to learn how to use the User class and have made a form, but cant get it to display the email, first_name and last_name fields, I have the following code:
forms.py:
from django import forms

from django.contrib.auth.forms import UserCreationForm
class RegistrationForm(UserCreationForm):
email = forms.EmailField(required = True)
class Meta:
model = User
fields = (
'username',
'email',
'first_name'
'password1',
'password2'
)
def save(self, commit = True):
user super(UserCreationForm, self).save(commit = False)
user.first_name = self.cleaned_data['first_name']
user.last_name = self.cleaned_data['last_name']
user.email = self.cleaned_data['email']
if commit:
user.save()
return user
views.py:
from django.shortcuts import render, redirect
from django.http import HttpResponse
from django.contrib.auth.forms import UserCreationForm
def index(request):
return HttpResponse('index page')
def register(request):
if request.method == 'POST':
form = UserCreationForm(request.POST)
if form.is_valid():
form.save()
return redirect('accounts')
else:
form = UserCreationForm()
return render(request, 'accounts/register.html', {'form': form})
# Create your views here.
register.html:
{% extends 'accounts/base.html' %}
{% block head %}
<title> Sign Up</title>
{% endblock %}
{% block body %}
<h2>Sign up</h2>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Sign up</button>
</form>
{% endblock %}
When I go to /accounts/register a form with username, password and password confirmation fields appear and the form works and saves to the database. But where are the first_name, last_name, email fields inlcuded in the User model?
Use RegistrationForm instead of UserCreationForm in your views
replace
from django.contrib.auth.forms import UserCreationForm
to
from .forms import RegistrationForm
form = RegistrationForm()
