How to create a UserProfile form in Django with first_name, last_name modifications?

Question

If think my question is pretty obvious and almost every developer working with UserProfile should be able to answer it.

However, I could not find any help on the django documentation or in the Django Book.

When you want to do a UserProfile form in with Django Forms, you'd like to modify the profile fields as well as some User field.

But there is no forms.UserProfileForm (yet?)!

How do you do that?

I stumbled across this today and after some googling I found a solution that is a bit cleaner in my opinion:

#in forms.py
class UserForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ["username", "email"]

class UserProfileForm(forms.ModelForm):
    class Meta:
        model = UserProfile

#in views.py
def add_user(request):
    ...
    if request.method == "POST":
        uform = UserForm(data = request.POST)
        pform = UserProfileForm(data = request.POST)
        if uform.is_valid() and pform.is_valid():
            user = uform.save()
            profile = pform.save(commit = False)
            profile.user = user
            profile.save()
            ....
    ...

#in template
<form method="post">
    {{ uform.as_p }}
    {{ pform.as_p }}
    <input type="submit" ...>
</form>

Here is how I finally did :

class UserProfileForm(forms.ModelForm):
    first_name = forms.CharField(label=_(u'Prénom'), max_length=30)
    last_name = forms.CharField(label=_(u'Nom'), max_length=30)

    def __init__(self, *args, **kw):
        super(UserProfileForm, self).__init__(*args, **kw)
        self.fields['first_name'].initial = self.instance.user.first_name
        self.fields['last_name'].initial = self.instance.user.last_name

        self.fields.keyOrder = [
            'first_name',
            'last_name',
            ...some_other...
            ]

    def save(self, *args, **kw):
        super(UserProfileForm, self).save(*args, **kw)
        self.instance.user.first_name = self.cleaned_data.get('first_name')
        self.instance.user.last_name = self.cleaned_data.get('last_name')
        self.instance.user.save()

    class Meta:
        model = UserProfile
