django - 重新排序模型表单字段

我需要重新排序来自另一个基类的模型形式的字段。找不到解决方案。以下代码段中的“地址”始终显示在HTML模板的开头。如何使用渲染的模板将其进一步下移？提前致谢。

class Address:
   street= ...
   city= ...

class Customer(Address):
   name = ...
   ...

class CustomerForm(ModelForm):
   def __init__(...)
        super(CustomerForm, self).__init__(*args, **kw)
        self.fields.keyOrder=[
        'name',
        'Address',  #<-- I want "Address" appear after the name in my template
                    #<-- This obviously is not the right code.
   class Meta:
      model = Customer

-P

最佳答案

重新排序非常繁琐:

# django's SortedDict stores ordering of its fields in this list-type attribute:
keyorder = self.fields.keyOrder

# Remove fields which we want to displace:
keyorder.remove('street')
keyorder.remove('city')

# Get position where we want them to put in:
i = keyorder.index('name') + 1

# Insert items back into the list:
keyorder[i:i] = ['city', 'street']

最好以正确的顺序再次列出所有字段:

class MyForm(ModelForm):
    class Meta:
       model=Customer
       fields=[..., 'name', 'street', 'city', ...]
