Much less controversial question this time, I hope ;-)
I have:
class MyModel(Base)

I want to do:
engine = create_engine(...)

...of course, this barfs the first time I run it as the table

well the easiest is mytable.drop(engine, checkfirst=True).
The check is not within the DropTable construct, which represents just the

Hmm, but both mysql and postgres (I suspect others do too, but I haven't checked) have
DROP TABLE IF EXISTS statements so you don't need to do any checking. That
feels like it should be supported by the DropTable construct, what am I missing?
oh,

I'm keeping a project that does pretty much the same as SQLSoup but

It also relies on the new Declarative Base and it doesn't rely on
anything from SQLSoup, so when Soup gets discontinued, SQLasagna will
go on :)
You can see the code, fork
while we are on the subject, i'd like to ask a question if i'm doing
it right or wrong.
i have created a class called Validation with a method called is_valid
and I have mixed it in my SQLAlchemy models. all of my models has an
attribute called validation that consists of model's attributes that
