I'm writing a section about migrating a database from SQLObject to
SQLAlchemy. I think I've found a minor usability wart: in SQLObject,
you can do "SomeClass.select().count()". In SQLAlchemy with
ActiveMapper, the equivalent is "list( Page.table.count().execute())[0]
[0]", which is a little painful. (Straight up SQLAlchemy without
ActiveMapper still seems a bit cumbersome, because Page.table is just
replaced by "page" or whatever table instance you might have defined...)
Am I missing some shortcut, or is this really the way to do this?
Glancing at the source, it looks like it you could add a method to ActiveMapperMeta like
def count(cls):
return cls.table.count().scalar()
add *args etc if desired...
