推荐答案

表单字段没有 null 或空白参数。这些仅用于模型场。对于表单字段，您只需要需要。

Form fields don't have null or blank arguments. Those are for model fields only. For form fields, you just have required.

但是，您应该真正使用 ModelForm 将从模型中为您创建表单域，并允许您保存。

However, you should really be using a ModelForm which will create the form fields for you from the model, and allow you to save it afterwards.
