[python][django] django forms super

在使用 django forms 時，有看到幾個django中super的用法，查了一些相關資料。


It’s important to remember to call the superclass method – that’s thatsuper(Blog, self).save(*args, **kwargs) business – to ensure that the object still gets saved into the database. If you forget to call the superclass method, the default behavior won’t happen and the database won’t get touched.



順帶查了 *args, **kwargs

It’s also important that you pass through the arguments that can be passed to the model method – that’s what the *args, **kwargs bit does. Django will, from time to time, extend the capabilities of built-in model methods, adding new arguments. If you use *args, **kwargs in your method definitions, you are guaranteed that your code will automatically support those arguments when they are added.
