python - 如何自动对 Django 表单字段进行排序

Question

我有一个像这样的 Django ModelForm:

class MyForm(forms.ModelForm):
    def make_this_fields_first(self, my_fields):
          # what can I do here?

    class Meta:
        model= MyModel
        fields = '__all__'

在我看来我想这样做:

my_form_obj = MyForm()
my_form_obj.make_this_fields_first(['field6','field3'])

Answer 1

您可以调用BaseForm 的order_fields()方法:

my_form_obj = MyForm()
my_form_obj.order_fields(['field6', 'field3'])

或者在 ModelForm 中的 Meta.fields被订购。表单字段将按照它们在此处定义的相同顺序生成:

class MyForm(forms.ModelForm):

    class Meta:
        model= MyModel
        fields = ['field6', 'field3', ...]
