PR: Ignore PySide6 QSqlDatabase.exec DeprecationWarning

[juliangilbey]

When running the package tests with PySide 6, the tests fail because PySide 6 gives a DeprecationWarning, and the pytest.ini settings turn this into an error. This PR ignores that specific error.

I tried using a warnings.catch_warnings() block in qtpy/QtSql.py around the deprecated functions, but pytest seems to ignore this. It might be worth adding such a block anyway.

Hi @juliangilbey thanks for the PR! So my guess is that doing something like:

def prevent_warn_exec(self, *args, **kwargs):
    with warnings.catch_warnings():
        warnings.simplefilter("ignore")
        self.exec(*args, **kwargs)

QSqlDatabase.exec_ = QSqlDatabase.exec = prevent_warn_exec

Didn't work, right? If that is the case then seems reasonable to just ignore the warning. Also what do you think @ccordoba12 ?

Also what do you think @ccordoba12 ?

I think we shouldn't ignore the warning with the approach you proposed so that users actually see it and learn that calling exec is deprecated.

So, I'm ok with @juliangilbey's simple approach of ignoring the warning in our tests so they pass.

Thanks @juliangilbey!
