我有这个非常奇怪的问题，一直无法弄清楚。我有一个带有 ChoiceFields 的表单，我从模型对象加载数据并将其设置为表单的初始值。只有一半的字段实际上被设置为对象指定的初始值。

继承人的形式

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')

这是我在视图中设置的

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)

唯一的问题是 mail_class 选择字段将在模板中设置为正确的值。package_type 都只是设置在第一个选项上。

我已经检查了作为初始值输入的值，它都符合选择...

有任何想法吗？

找出问题所在及其在数据库本身中。

所有包类型的末尾都有一些空字符。

现在进入那个谜。
