带有clean的Django验证不起作用

Question

我的views.py

class AccountListView(ListView):
    context_object_name = 'accounts'
    model = models.Account

class AccountCreateView(CreateView):
    fields = ('foo', 'bar')
    model = models.Account

我的forms.py

class AccountForm(forms.ModelForm):
    foo = forms.ModelDecimalField()
    bar = forms.ModelDateField()

    def clean_foo(self):
        foo_passed = self.cleaned_data.get("foo")
        if foo_passed > 1000:
            raise forms.ValidationError("Sorry, Maximum is 1000.")
        return foo_passed

我的template.html

{{form.as_p}}

在我上面的代码中，我正在尝试验证输入，如果值大于1000将引发错误。但它不起作用，我想念的是

您需要告诉视图使用窗体类：

class AccountCreateView(CreateView):
    fields = ('foo', 'bar')
    model = models.Account
    form_class = AccountForm
