Async MongoDB with vanilla Pydantic v2+ - made easy.

Hi,

I’m Peter Volf, SW engineer for many years now with a master's degree in computer science, located in Hungary.

My main professional interest has been Python ever since I first started using it around ~2008. I really enjoy working with React and TypeScript, and doing full-stack application development as well. I'm also interested in Linux and the open-source world in general. At university, I specialized in network/graph analysis and machine learning -- it was a long time ago, it would be great to have the time to pick these up again.

I work mostly on greenfield web projects. When my time allows -- unfortunately not nearly as often as I'd like these days -- I like to do some open-source work.

Some of my more interesting hobby projects are:

• localclustering is a local graph clustering algorithm with a graphscraper backend (JOSS publication, analysis).
• motorhead is an async almost-ODM for MongoDB with vanilla Pydantic v2.
• fasthx is an HTMX utility for FastAPI.
• graphscraper is an SQL graph database with an in-memory cache and a built-in, on-demand web scraper.
• mastodon-social-graph is a graphscraper implementation that loads the social graph of a Mastodon instance.
• uspto-patent-citation-graph is a graphscraper implementation that loads the citation graph from USPTO's API.
• markyp is an XML templating engine and parser tool.
• markyp-html is an HTML implementation based on markyp that lets you write static webpages 100% in Python (i.e., without Jinja-like templating).
• markyp-bootstrap4 is a full Bootstrap4 implementation based on markyp-html.

My recent professional projects:

• Currently I work on AI-assisted digital healthcare services AIP Clinic and AIP Derm, on the LNGx platform, and on various internal business tools.
• Horizon Planner, an enterprise resource planning and project management application (tech lead/principal engineer, 2019-2023).

I also tutor engineers, from juniors to seniors, primarily focusing on Python and system architecture/design.

I'm available for consulting and contract work, you can find me on:

• Linkedin
• Mastodon
• GitLab
• Twitter

How to ? Update(PUT) a field with default_factory=datetime.now ?

Hi,

Maybe someone could help...
I want to update a field "last_update" with "datetime.now" each time a PUT request is validate, and to store this key as Date type in mongodb

The only solution I've found is to add the key:value directly in the dict in my "_convert_for_update" function... But i'm not really satisfied with this solution. Maybe there is a better and proper way to do that ?

Here is my basic UserUpdate class:

class UserUpdate(BaseDocument):
    """
    User update model
    """
    name: str | None = None
    surname: str | None = None
    email: EmailStr | None = None
    nickname: str | None = None
    last_update: UTCDatetime = Field(default_factory=datetime.now)

and here my "_convert_for_update" function:

    async def _convert_for_update(self, data: UserUpdate) -> UpdateObject:
        result_dict = {**(await super()._convert_for_update(data))}
        result_dict['$set'].update({'last_update': data.last_update})
        return result_dict
