So I’ve created 3 different users: admins, developers, and project managers. When I use the individual signup forms for each of these users and log out, it works, but then I when try to use the login form, it seems to me that it’s acting like the signup form. Because when I input the same user details as the one I just created into the login form, it throws up the built-in error message, 'A user with that user name already exists' I’m not sure how to proceed from here.
Here’s what I have so far.
models.py
class CustomUser(AbstractUser):
ACCOUNT_TYPE_CHOICES = (
('admin', 'Admin'),
('developer', 'Developer'),
('project_manager', 'Project Manager')
)
account_type = models.CharField(max_length=20, choices=ACCOUNT_TYPE_CHOICES)
login and signupviews
class LoginView(View):
def get(self, request):
# Render the login form
form = LoginForm()
return render(request, 'users/login.html', {'form': form})
def post(self, request):
# Get the form data from the request
form = LoginForm(request.POST)
# Validate the form data
if form.is_valid():
# Get the username and password from the form
username = form.cleaned_data['username']
password = form.cleaned_data['password']
# Authenticate the user
user = authenticate(request, username=username, password=password)
# If the user is authenticated, log them in and redirect to the homepage
if user is not None:
login(request, user)
if user.account_type == 'admin':
return redirect('admin_home')
elif user.account_type == 'developer':
return redirect('developer_home')
elif user.account_type == 'project_manager':
return redirect('projectmanager_home')
return redirect('home')
# If the user is not authenticated, render the login form again with an error message
else:
form.add_error(None, 'Invalid username or password')
return render(request, 'users/login.html', {'form': form})
else:
return render(request, 'users/login.html', {'form': form})

return redirect(self.success_url)
