Question

#models.py

class Profile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    birthday = models.DateField(blank=True, null=True)

我将django.contrib.auth.views.models.User扩展为其他信息，例如生日等。问题是我无法在birthday中使用request.user.profile访问views.py。我不得不使用额外的小部件来使应用程序更直观。

我是这样做的：

#forms.py
class ProfileEditForm(forms.ModelForm):
    birthday = forms.DateField(widget=extras.SelectDateWidget)

    class Meta:
        model = Profile
        fields = ('photo', 'phone_num', 'nationality', 'gender')

#views.py
@login_required
def edit(request):
    if request.method == 'POST':
        user_form = UserEditForm(instance = request.user,
                                 data = request.POST)
        profile_form = ProfileEditForm(instance = request.user.profile,
                                       data = request.POST,
                                       files = request.FILES)
        if user_form.is_valid() and profile_form.is_valid():
            request.user.profile.birthday = user_form.cleaned_data['birthday']
            user_form.save()
            profile_form.save()
    else:
        user_form = UserEditForm(instance=request.user)
        profile_form = ProfileEditForm(
            instance = request.user.profile
        )
    return render(request,
                  'views/edit_profile.html',
                  {'user_form' : user_form,
                   'profile_form' : profile_form})

Answer 1

正如@Alasdair所提到的，您需要更正UserEditForm类。回到自定义小部件，你可以做

class ProfileEditForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ('photo', 'phone_num', 'nationality', 'gender', 'birthday')
        widgets = {
            'birthday': extras.SelectDateWidget,
        }

在django auth.user模型扩展中接近属性
