✨ Add field-level db comments when a field description exists

[iloveitaly]

This PR fixes #492 (comment) by adding column-level db comments
when a field description exists.

I can add some tests if this is the sort of PR that would be accepted.

I've implemented this in my SQLModel extension here: https://github.com/iloveitaly/activemodel/blob/master/activemodel/get_column_from_field_patch.py

Details:

• feat: pull field descriptions into db comments
• docs: document autostring
• feat: add use_attribute_docstrings pydantic config for improved docstrings

Hi, thanks for the contribution!

There are some linting errors and test failures - could you look into those? It will facilitate the review process if the CI is green. I'll go ahead and put this PR in draft in the meantime 🙏

@svlandeg awesome, will work on CI and we can go from there! Is there anything else that I should work on in order to get this merged?

A test case is always useful, as it helps the reviewer as well to quickly run a small example. And it'll likely be necessary anyway to get the test coverage back to 100% (ensuring that all code in the code base gets tested).

Awesome, I should have some time to help there. I have a bunch of other SQLModel improvements I'd love to pull over from activemodel, so understanding the best contribution flow would be really helpful
