Support auto generate UUID for non pk field

First, Thank you for support nice software 😃 I find that UUIDField only auto generate UUID4 only that field is primary key. How about support auto generate UUID key for non pk field?

Maybe we can use like below

uid = fields.UUIDField(auto_generate=True) # default : False

Also, I’m not good at orm and database well. I want to hear about other’s opinions. I really appreciate if anyone answer to me! Thank you 👍

Hi!

Actually, for pk uuid fields generation is done inside of Tortoise just like that:

    def __init__(self, **kwargs) -> None:
        if kwargs.get("pk", False):
            if "default" not in kwargs:
                kwargs["default"] = uuid4
        super().__init__(**kwargs)

So, if you wanna same behaviour for non-pk uuid field you just have to do it like that:

from uuid import uuid4
...
uid = fields.UUIDField(default=uuid4)

Yes, I have been having to do many support queries where the docs either had something missing, or was hard to find. We need doc guidelines.
