为什么Django的Meta是一个老式的类？ [英] Why is Django's Meta an old-style class?

问题描述

我注意到，在Django模型中，有一个类Meta ，它对模型做了一些额外的定义。

<我的问题是，为什么这是一个老式的类？ （即不是子类化对象？）有这样的原因或者这只是一个自定义？

解决方案

我相信没有什么真正的原因，因为自Python 2.2以来存在新式类），并且不仅可以选择使用新式类，而且可能是一个好主意（因为所有通常的原因）。

I noticed that in Django models, there is a class Meta which makes some additional definitions about the model.

My question is, why is this done as an old-style class? (i.e. not subclassing object?) Is there a reason for this or is this just a custom? Could I do it as a new-style class in my projects?

解决方案

I believe that there is no real reason (including history, since new-style classes exist since Python 2.2) and that not only can you choose to use a new-style class instead, but that it would probably be a good idea for you to do so (for all the usual reasons).
