How to update django auth User using a custom form - django

Question

I am using Django's built in authentication to manage users on a social media website. I am using a one-to-one relationship to attach a profile to each user. I can update all the parts of the profile I have attached using an UpdateView. However I don't know how to do that with Django's built in User. So I created a form that uses the _meta class. I have gotten to the point where my form will add a new user instead of update the current one. I was hoping one of you could help me fix my code. Thanks in advance for any help you can offer
views.py
class PrivProfileUpdate(View):
form_class = UserUpdateForm
template_name = 'user/user_form.html'
#display a blank form
def get(self, request, pk):
form = self.form_class(None)
return render(request, self.template_name, {'form': form})
#proces form data
def post(self, request, pk):
form = self.form_class(request.POST)
user = User.objects.get(pk=pk)
if form.is_valid():
user = form.save(commit=True)
print("we are trying to save")
#cleaned (normalized) data
username = form.cleaned_data['username']
password = form.cleaned_data['password']
first_name = form.cleaned_data['first_name']
last_name = form.cleaned_data['last_name']
email = form.cleaned_data['email']
user.set_password(password) #this is the only way to change a password because of hashing
user.save()
return render(request, self.template_name,{'form': form})
forms.py
class UserUpdateForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput)
class Meta:
model = User
fields = ['username', 'email', 'password', 'first_name', 'last_name']
SOLUTION:
in views.py
class PrivProfileUpdate(UpdateView):
model = User
form_class = UserUpdateForm
template_name = 'user/user_form.html'
def form_valid(self, form):
user = form.save(commit=True)
password = form.cleaned_data['password']
user.set_password(password)
user.save()
return redirect('user:index')

There's nothing special about the User class here. Just as with any other model, to update an existing instance you pass it as the instance argument to the form.
However, you do not actually need to do this at all yourself. You should be using an UpdateView, which does this for you; then you do not need to define get and post. The only method you need to define here is form_valid, to set the password:
class PrivProfileUpdate(UpdateView):
form_class = UserUpdateForm
template_name = 'user/user_form.html'
def form_valid(self, form):
user = form.save(commit=True)
password = form.cleaned_data['password']
user.set_password(password)
user.save()
return HttpResponseRedirect(self.get_success_url())
