这是我最终的做法：
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
