django - Django, Set some values of a form field in the model

Question

It's a bit odd but I would like to define some properties of a form field like its widget or class from the model definition. I know it is easy from the form but I'd like to know if it's possible from the model. I'm not sure but I think I remember having seen something like that some day.

好吧，您可以创建自己的模型字段子类并重新定义它们的formfield方法以添加您想要的属性，但可能不值得付出努力，因为您将被覆盖。然而，那是小时电话。

无论如何，如果您决定尝试此操作，请确保遵循文档中的这两个部分： ModelForms 和自定义字段 以及 将模型字段的表单字段指定为默认实现Field.formfield做一些您通常不想做的重要事情忽略。
