Question

我正在创建具有初始数据的ModelForms。 UserSettingsForm工作，但AddressSettingsForm不工作。它给出了AttributeError＆＃39; User＆＃39;对象没有属性＆＃39; get＆＃39;。我创建AddressSettingsForm的方式与我创建UserSettingsForm的方式相同，但是它给出了一个错误。 Django调试页面没有给出错误来源。它只是告诉我错误是在AddressSettingsForm中。有谁看到我的错误？

forms.py

class UserSettingsForm(forms.ModelForm):
    class Meta:
        model = User
        exclude = ['role', 'address', 'is_active', 'is_admin', 'last_login', 'password']

    def __init__(self, user, *args, **kwargs):
        super(UserSettingsForm, self).__init__(*args, **kwargs)
        self.fields['first_name'].initial = user.first_name
        self.fields['last_name'].initial = user.last_name
        self.fields['email'].initial = user.email
        self.fields['phone'].initial = user.phone

class AddressSettingsForm(forms.ModelForm):
    class Meta:
        model = Address
        exclude = ['name']

    def __init__(self, address, *args, **kwargs):
        super(AddressSettingsForm, self).__init__(*args, **kwargs)
        self.fields['street'].initial = address.street
        self.fields['city'].initial = address.city
        self.fields['state'].initial = address.state
        self.fields['zip'].initial = address.zip

views.py

@login_required
def settings(request, template):
    if request.method == 'POST':
        user_settings_form = UserSettingsForm(request.POST, request.user)
        address_settings_form = AddressSettingsForm(request.POST, request.user.address)

        if user_settings_form.is_valid() and address_form.is_valid():
            address = Address(name=request.user.first_name + ' ' + request.user.last_name, **address_form.cleaned_data)
            user = request.user

            user.first_name = user_settings_form.cleaned_data['first_name']
            user.last_name = user_settings_form.cleaned_data['last_name']
            user.email = user_settings_form.cleaned_data['email']
            user.phone = user_settings_form.cleaned_data['phone']
            user.address = address
            user.save()

    else:
        user_settings_form = UserSettingsForm(request.user)
        address_settings_form = AddressForm(request.user)

    return render(request, template, { 'user_settings_form': user_settings_form, 'address_settings_form': address_settings_form, 'path' : request.path, 'is_logged_in': request.user.is_authenticated })

错误：

Answer 1

在views.py最终else条款中，您正使用AddressForm初始化request.user。您在request.user.address传递的代码中的上方。您还试图初始化AddressForm而不是AddressSettingsForm。

两种__init__方法都希望user或address作为第一个参数。然而，如果它是POST请求，则在POST数据之后将其作为第二个参数传递。尝试交换订单。

这样做：

if request.method == 'POST':
    user_settings_form = UserSettingsForm(request.user, request.POST)
    address_settings_form = AddressSettingsForm(request.user.address, request.POST)

...

else:
    user_settings_form = UserSettingsForm(request.user)
    address_settings_form = AddressSettingsForm(request.user.address)
