[Query] Common ORM like functionalities about beanie HOT 8 CLOSED

Hey, sorry for the late reply.

I think you can do the thing with the next code:

from datetime import datetime
from typing import Optional

from pydantic import Field

from beanie import Document, before_event, Replace, Insert


class Sample(Document):
    created_at: datetime = Field(default_factory=datetime.utcnow)
    updated_at: Optional[datetime] = None

    @before_event([Insert, Replace])
    def set_updated_at(self):
        self.updated_at = datetime.utcnow()

The updated_at field will be updated only before inserts and replaces here (and before save(), as it is a combination of replace and insert methods). But probably this is enough.

The doc about before_event could be found here: https://roman-right.github.io/beanie/tutorial/event-based-actions/

I would like to know too

Thank you, Roman

I am referring to the document link you have posted but some how I missed this detail.

Can I use the Sample class as a mixin? The code below does not work (updated_at in ChatModel does not update)

class TimeBaseModel(Document):
    created_at: datetime = Field(default_factory=datetime.utcnow)
    updated_at: Optional[datetime] = None

    @before_event([Insert, Replace, SaveChanges])
    def set_updated_at(self):
        print("updated")
        self.updated_at = datetime.utcnow()


class ChatModel(TimeBaseModel):
    id: int = Field(alias="_id")
    type: str = Field(...)

    class Collection:
        name = "ChatModel"`

Hey @rdfsx ,
Unfortunately, nope. I will fix this, but for now, it works only directly with the classes. It should be fixed in a week or two

Okay, thank you for your work!

Hey @rdfsx ,
It was fixed in 1.8.3 - you can inherit documents with actions now.
