Register, Login, Logout with django class based views - python-3.8

Question

I am trying to make an authentication system with django class based views
What I have tried so far:
This is my views.py file:
from django.shortcuts import render
from django.views import generic
from .forms import UserRegistrationForm
from django.urls import reverse_lazy
class UserCreationView(generic.CreateView):
form_class = UserRegistrationForm
template_name = 'registration/register.html'
success_url = reverse_lazy('login')
This is forms.py file
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
class UserRegistrationForm(UserCreationForm):
email = forms.EmailField()
class Meta:
model = User
fields = ('username', 'email', 'password1', 'password2',)
widgets = {
'email': forms.EmailInput(attrs={'class':'input', 'placeholder': 'Email Address'})
}
This the urls.py file:
from django.urls import path
from .views import UserCreationView
urlpatterns = [
path('register/', UserCreationView.as_view(), name = 'register'),
]
Other urls.py file(urls.py file present in project folder)
path('users/', include(urls)),
path('users/', include('authentication.urls')),
The problem with this code is Whenever I login I can still login and register by going to the login url(login url in this case:http://localhost:8000/users/login/), How can I restrict user to log in again

Answer 1

I found out that the default LoginView() class on
django.contrib.auth import views
has a boolean attribute called
redirect_authenticated_user
And I believe this is what you are looking for.
Just look for class LoginView in https://docs.djangoproject.com/en/3.2/topics/auth/default/ and you will see it.
