Django: Changing User Profile by forms

I am using UserProfile to save some fields that I created. Its working fine. But I would like to create a new view to let 开发者_运维问答user change (update) theses fields values. But, theses values arent being showing in form. Anyone have any idea how to fix it?

view.py

@login_required

    def atualizar_cadastro_usuario(request):    
        if request.method == 'POST':       
            form = cadastrousuarioForm(request.POST,instance=request.user.get_profile())


            if form.is_valid():            
                new_user = form.save()            
                return render_to_response("registration/cadastro_concluido.html",{})
        else:    
            form = cadastrousuarioForm(request.POST,instance=request.user.get_profile())
        return render_to_response("registration/registration.html", {'form': form})

form.py

class cadastrousuarioForm(UserCreationForm):   
    username = forms.EmailField(label = "Email",widget=forms.TextInput(attrs={'size':'60','maxlength':'75'}))
    email = forms.EmailField(label = "Digite o Email novamente",widget=forms.TextInput(attrs={'size':'60','maxlength':'75'}))
    nome = forms.CharField(label = 'Nome',widget=forms.TextInput(attrs={'size':'30','maxlength':'100'}))
    cpf = BRCPFField(label='CPF')
    data_nascimento=forms.DateField(widget=forms.DateInput(format = '%d/%m/%Y'), input_formats=('%d/%m/%Y',))    
    endereco = forms.CharField(label = 'Endereço',widget=forms.TextInput(attrs={'size':'30','maxlength':'100'}))
    cidade = forms.CharField(label = 'Cidade')
    estado = forms.CharField(widget=BRStateSelect(), label='Estado', initial = 'SP') 
    telefone = forms.CharField(label = "Telefone",widget=forms.TextInput(attrs={'size':'12','maxlength':'12'}))
    escolaridade = forms.ChoiceField(choices=UserProfile.ESCOLARIDADE_ESCOLHAS)    
    profissao = forms.CharField(label = 'Profissão')
    empresa = forms.CharField(label = 'Empresa',required=False) 
    receber_emails = forms.ChoiceField(choices=UserProfile.QUESTIONARIO_ESCOLHAS)     
    #captcha = CaptchaField(label = 'Digite as letras a seguir')

    class Meta:
        model = User
        fields = ("username","email")


    def save(self, commit=True):
        user = super(cadastrousuarioForm, self).save(commit=False)  
... 

In bash, it works fine:

>>> from django.contrib.auth.models import User
>>> from cadastro.models import UserProfile
>>> u = User.objects.get(username='user@gmail.com')
>>> u.get_profile().telefone
u'123123455'

You need to change your model in the form from User to UserProfile. The form also needs to subclass ModelForm rather than UserCreationForm. Also, it looks like you're only using a subset of fields in your ModelForm (username and email). Finally, since you're using a ModelForm you don't need to define all of the model's fields in your form. Try changing your cadastrousuarioForm to the following:

class cadastrousuarioForm(ModelForm):   
    class Meta:
        model = UserProfile
        fields = ('username','email')
    def save(self, commit=True):
        user = super(cadastrousuarioForm, self).save(commit=False)
