Es gibt zwei Hauptunterschiede zu einer normalen *Pfadoperation*:

所有数据转换、校验、文档等功能仍将正常运行。

这样，就可以仅声明模型之间的差异部分（具有明文的 `password`、具有 `hashed_password` 以及不包括密码）。

通过这种方式，可以只声明模型之间的区别（分别包含明文密码、哈希密码，以及无密码的模型）。

Auf diese Weise beschreiben wir nur noch die Unterschiede zwischen den Modellen (mit Klartext-`password`, mit `hashed_password`, und ohne Passwort):

There are 2 main differences from a normal *path operation*:

That way, we can declare just the differences between the models (with plaintext `password`, with `hashed_password` and without password):
