Can we add unit tests ?

Can we add unit tests ?

What would be a good test? I don't know how to write tests for different SA versions.

I guess just a test for relationships would work.

OK, but there are plenty of those already. It would be nice if we could prove that it works for both 1.4.36 and older versions of SQLAlchemy.

Right - apparently tests just have not been run in Github Actions in 16d so the breakage does not show.

I don't think a test in itself can define the lib version but that would require something more, maybe like a branch where a different SA version is pinned.

Running tests without the fix results in broken tests, running with fix all tests pass. You can run them locally to verify

Any updates on when this will be merged? The issue is critical

[bharathanr]

Hi! Is there anything we can do to help with merging this pull request? It's rather critical, so if there's something that can be done, it would be great. I'm willing to put in some time to help.

@tiangolo Can you take a look at this, please? It is nasty that you have to pin the version of sqlalchemy at the moment. It would be nice if you could make a release after the merge so that the current version of sqlalchemy can be used again.

In this PR (https://github.com/leynier/sqlmodel/pull/37) pointing to a fork, you can see that the tests are successful. I think that It is not necessary to add extra tests for this PR because the existing tests validate the change since without the change of this PR the tests fail.
