Django ChoiceField初始值未設置爲所有ChoiceFields

我有這個真正奇怪的問題布萊恩，並沒有能夠弄明白。我有一個帶有ChoiceField的表單，我從一個模型對象中加載數據並將其設置爲表單的初始值。實際上只有一半的字段被設置爲該對象指定的初始值。Django ChoiceField初始值未設置爲所有ChoiceFields

繼承人的形式

sku = forms.CharField(max_length=200, required=True) 
weight = forms.DecimalField(min_value=.1, max_digits=4, decimal_places=1, required=True, help_text="Enter Weight In Pounds") 
mail_class = forms.ChoiceField(choices=MAIL_CLASS, required=True) 
package_type = forms.ChoiceField(choices=PACKAGE_TYPE, required=True) 
shipping_rule = forms.IntegerField(min_value=1, required=False) 
new_weight = forms.DecimalField(min_value=.1, max_digits=4, decimal_places=1, required=False, help_text="Enter Weight for new shipping method In Pounds") 
new_mail_class = forms.ChoiceField(choices=MAIL_CLASS, required=False, initial='None') 
new_package_type = forms.ChoiceField(choices=PACKAGE_TYPE, required=False, initial='None') 
max_shipping_rule = forms.IntegerField(min_value=2, required=False) 
max_weight = forms.DecimalField(min_value=.1, max_digits=4, decimal_places=1, required=False, help_text="Enter Weight for new shipping method In Pounds") 
max_mail_class = forms.ChoiceField(choices=MAIL_CLASS, required=False, initial='None') 
max_package_type = forms.ChoiceField(choices=PACKAGE_TYPE, required=False, initial='None')

而且繼承人是我設置視圖

data = { 
     'sku': shipping_info.sku, 
     'weight': shipping_info.weight, 
     'mail_class': shipping_info.mailclass, 
     'package_type': shipping_info.packagetype, 
     'shipping_rule': shipping_info.shippingrule, 
     'new_weight': shipping_info.newweight, 
     'new_mail_class': shipping_info.newmailclass, 
     'new_package_type': shipping_info.newpackagetype, 
     'max_shipping_rule': shipping_info.maxshippingrule, 
     'max_weight': shipping_info.newmaxweight, 
     'max_mail_class': shipping_info.maxmailclass, 
     'max_package_type': shipping_info.maxpackagetype 
    } 

    form = ShippingType(initial=data)

只是問題是mail_class choicefields將被設置爲在模板中的權值。儘管package_type只是在第一個選項上設置的。

我已經檢查越來越把值作爲inital，這一切

任何想法相匹配，以選擇......？

找出問題出在哪裏，它在數據庫本身。

所有包類型的末尾都有一些空字符。

現在到那個謎。
