I have a handful of functions within an application's "library api" that
share a similar intent in functionality and return values, but query for
discrete types of objects. I'm working on standardizing them right now and
could use some feedback.
case 1 is simple:
results = dbSession.query(Foo.id, case(..)).all()
results is a `list`
results[0] is an instance of `sqlalchemy.util._collections.result`
case 2 is where i'm stuck - some queries are a bit complex and still in raw
SQL..
results = dbSession.execute(text("SELECT id, id_bar FROM foo WHERE
...")).all()
results is a `sqlalchemy.engine.result.ResultProxy` instance
if I consume all rows as `results = [i for i in results]`
then `results[0]` is a `sqlalchemy.engine.result.RowProxy`
I need to ensure the latter form is a list of tuples, like the former, so
it can be used by various encoders and libraries that look for a list/tuple
in that objects MRO.
Right now I'm manually doing this and documenting the rationale. But is
there anything in the sqlalchemy api that would streamline turning the
second form into something where a tuple/list is involved - perhaps
bypassing the RowProxy step? I couldn't find anything in the docs.
