Django user registration without username

I am making django registration form

At first this code works well

class RegisterForm(UserCreationForm):
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ["username","email", "password1", "password2"]

def register(response):
    if response.method == "POST":
        form = RegisterForm(response.POST)
        if form.is_valid():
            form.save()
        return redirect("/login")

However now I want to make email as username, so my idea is like this

class RegisterForm(UserCreationForm): email = forms.EmailField()

class Meta:
    model = User
    fields = ["email", "password1", "password2"] #delete username from home.

def register(response):
    if response.method == "POST":
        if not response.POST._mutable:
            response.POST._mutable = True
        response.POST['username'] = random.randrange(1000000) # force change username
        form = RegisterForm(response.POST)
        if form.is_valid():
            form.save()

However after this username is not registered.

What is wrong??

However after this username is not registered.

It is not registered, since the form does not contain a field named username, and thus the form will ignore this.

You can set a username with:

form = RegisterForm(response.POST)
if form.is_valid():
    form.instance.username = f'{random.randrange(10000000)}'
    form.save()

That being said, it might be better to implement a custom user model, and set email as the USERNAME_FIELD. In that case your user model, does not have a username field.
