Django:通过表单修改用户配置文件

Question

我使用UserProfile来保存我创建的一些字段。它工作得很好。但我想创建一个新的视图，让用户更改(更新)这些字段的值。但是，这些值并没有在表格中显示出来。有人知道怎么修吗?

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)  
... 

在bash中，它可以正常工作:

>>> from django.contrib.auth.models import User
>>> from cadastro.models import UserProfile
>>> u = User.objects.get(username='[e-mail]')
>>> u.get_profile().telefone
u'123123455'

您需要将表单中的模型从User更改为UserProfile。表单还需要子类ModelForm而不是UserCreationForm。此外，看起来您只在ModelForm (username和email)中使用字段的子集。最后，由于使用的是ModelForm，因此不需要在表单中定义模型的所有字段。尝试将cadastrousuarioForm更改为以下内容:

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