如果您有自定义模板和视图，您可以排除该字段并使用 {{ modelform.instance.field }} 获得价值.

If you have a custom template and view you may exclude the field and use {{ modelform.instance.field }} to get the value.

您也可能更喜欢在视图中使用:

also you may prefer to use in the view:

form.fields['field_name'].widget = forms.HiddenInput()

但我不确定它会保护帖子的保存方法.

but I'm not sure it will protect save method on post.

希望有帮助.
