尝试生成已清理的数据（）时出错！姜

Question

必须是简单的解决方案。但我看不出来。请帮帮我。“gorod”似乎在请求中，但当我尝试cleaned_data（）时，它会给我KeyError

KeyError at /ticket/

'gorod'

Request Method:     POST
Request URL:    http://localhost:8000/ticket/
Exception Type:     KeyError
Exception Value:    

'gorod'

Exception Location:     C:\Documents and Settings\POLINOM\web\website\orders\views.py in SaveOrder2, line 93

我的表格：

^{pr2}$

这是从以下形式继承而来的：

class AddressForm(forms.Form):
    address = forms.CharField(label=u"Адрес",max_length=200,required=True,widget=forms.TextInput(attrs={'size':60}))
    city = forms.CharField(label=u"Город",max_length=50,required=True)
    country = forms.ChoiceField(label=u"Страна",required=True,choices=COUNTRIES)
    state = forms.ChoiceField(label=u"Штат/Провинция",required=False, choices=StateProvince().get_all_states(), error_messages={'invalid_choice':u'нет среди допустимых значений. Пожалуйста, выберите правильный вариант'}) 
    zip = forms.CharField(label=u"Почтовый код",max_length=10,widget=forms.TextInput(attrs={'size':8}),required=True)
    phone_number = forms.CharField(label=u"Номер телефона",required=False)

我正在使用两种模型：

class Order(models.Model):
    STATUS_CHOICES=[
                    (1, 'Send'),
                    (0, 'Not_send'),                    
                ]
    user=models.ForeignKey(User)
    product=models.ForeignKey(Product)
    status = models.CharField(max_length=1,choices=STATUS_CHOICES)
    country = models.CharField(max_length=2)
    state = models.CharField(max_length=50) 
    zip = models.CharField(max_length=10)
    city = models.CharField(max_length=50)
    street = models.CharField(max_length=200)
    phone=models.CharField(max_length=20)


    def __unicode__(self):
        return 'Order by ' + self.user

class TicketProp(models.Model):
    order=models.ForeignKey(Order)
    note=models.CharField(max_length=1500)
gorod=models.CharField(max_length=2)

Answer 1

可能您的AddressForm类缺少gorod字段？表单填充.cleaned_data属性（后面没有()！-)基于表单中的字段；例如，在the source中，对于当前的django.forms，您将在第274行看到

for name, field in self.fields.items():

在循环的主体中，.cleaned_datadict被填充。在

那么你的AddressForm代码是什么（以及它可能使用的模型的代码）。。。？在
