Autocompletion not working in VS Code with Pydantic

[holyoaks]

Initial Checks

• I confirm that I'm using Pydantic V2

Description

I followed the instructions at https://docs.pydantic.dev/latest/integrations/visual_studio_code/#configure-vs-code but no matter what I do, I do not get autocompletion. I'm using Pylance (as noted in the docs, the default) as my language server, and can confirm Pydantic ==2.6.4 is installed in my virtual environment that VS Code is using. When I enable basic | standard | strict type checking in VS Code, I DO get type checking, but I always get BaseModelSubclass(**data) as the autocomplete for all of my Pydantic BaseModel subclasses. What might be wrong here?

@holyoaks,

Thanks for reporting. I'm not sure what the issue is - maybe someone else from the community has experienced this problem / has a fix? Can leave this open for now 👍

Could you share a screenshot of what you get in VSCode?

[holyoaks]

A better one

Interesting, it shows the signature of BaseModel and not Test 🤔

I see a warning on your BaseModel import, what is it saying? I'm guessing you are already on the latest version of Pylance, but could you also give your current version?

[holyoaks]

@Viicos That's simply a Ruff warning (Import block is un-sorted or un-formatted Ruff I001; I had not yet saved the file when I made the screenshot. My version of Pylance is v2024.4.1

[holyoaks]

As of today, without any changes on my part (that I'm aware of) the autocompletion started working. I have no idea.

Haha, ok! Marking as resolved then. Thanks @holyoaks!
