Password not saving when creating user - django

Question

I know there are hundreds of posts about that topic but, in all of them, there is something slightly different from my own program and I can't adapt it to my program because the Django way of handling password is such a mess that I understand nothing. A little help would be greatly appreciated, I thank you in advance.
So, when a new user registers, everything works perfectly but, somehow, the password is not saved in the database. When I go to the admin interface, it tells me that the password format is invalid or the hashag function is not known.
Here is my code :
Forms.py
class InscriptionForm(forms.ModelForm):
class Meta:
model = User
fields = ['username', 'first_name', 'last_name', 'email', 'password']
widgets = {'username': forms.TextInput(attrs={'class': 'form-control'}),
'first_name': forms.TextInput(attrs={'class': 'form-control'}),
'last_name': forms.TextInput(attrs={'class': 'form-control'}),
'email': forms.EmailInput(attrs={'class': 'form-control'}),
'password': forms.PasswordInput(attrs={'class': 'form-control'})}
def clean_password(self):
password = self.cleaned_data['password']
try:
validate_password(password, user=self)
except forms.ValidationError:
self.add_error('password', password_validators_help_texts())
return password
Views.py
def inscription(request):
if request.method == "POST":
form = InscriptionForm(request.POST)
if form.is_valid():
new_user = form.save()
authenticate(username=form.cleaned_data['username'], password=form.cleaned_data['password'],)
login(request, new_user)
request.session['is_connected'] = True
return redirect(inscription_suite)
else:
form = InscriptionForm()
return render(request, 'inscription/inscription.html', {'form': form})
I already tried modifying the view like this :
def inscription(request):
if request.method == "POST":
form = InscriptionForm(request.POST)
if form.is_valid():
new_user = form.save(commit=False)
new_user.password = make_password(form.cleaned_data['password'])
authenticate(username=form.cleaned_data['username'], password=form.cleaned_data['password'],)
login(request, new_user)
new_user.save()
request.session['is_connected'] = True
return redirect(inscription_suite)
else:
form = InscriptionForm()
return render(request, 'inscription/inscription.html', {'form': form})
But it raises the following error ValueError at /inscription
Cannot force an update in save() with no primary key.
Can someone help me please ?
Thanks in advance !

You must save password using set_password().
def inscription(request):
if request.method == "POST":
form = InscriptionForm(request.POST)
if form.is_valid():
new_user = form.save(commit=False)
password = form.cleaned_data['password'] # get password
new_user.set_password(password) # set the password
new_user.save() # save the user
authenticate(username=form.cleaned_data['username'], password=form.cleaned_data['password'],)
login(request, new_user)
request.session['is_connected'] = True
return redirect(inscription_suite)
else:
form = InscriptionForm()
return render(request, 'inscription/inscription.html', {'form': form})
