我正在尝试使用__init__参数将变量传递给 ModelForm clean 方法，但到目前为止还没有成功 - 我查看了 StackOverflow 上的各种帖子，但似乎没有一个有帮助。

我的代码如下：

forms.py

class property_booking_form(forms.ModelForm):
    check_in_date = forms.DateField(widget=SelectDateWidget)
    check_out_date = forms.DateField(widget=SelectDateWidget)

    class Meta:
        model = Properties_bookings
        fields = ['check_in_date', 'check_out_date']

    def __init__(self, property_id):
        self.property_id = property_id
        super(property_booking_form, self).__init__(self, property_id)

    def clean(self):
        check_in_date = self.cleaned_data.get('check_in_date')
        check_out_date = self.cleaned_data.get('check_out_date')
        property_min_nights = Properties.objects.get(id=self.property_id).property_minimum_nights
        ...

views.py

def view(request):
    ...
    if request.method == 'POST':
        booking_form = property_booking_form(request.POST, property_id=property_id)
        if booking_form.is_valid():
            ...
    else:
        booking_form = property_booking_form(property_id=property_id)
    return render(...)

这会引发以下错误：“property_booking_form”对象没有属性“get”

根据错误描述，这似乎与小部件有关：

异常位置：

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/forms/widgets.py in value_from_datadict, line 1058

该表单在没有覆盖的情况下工作正常 …
