if A points to B1, copying B1 to B2 is ok, b
the copy can be a dummy non-db-aware - if that is ok in your case
there's yet another option; u can just go all over the original
object, and on cancel do a rollback, and restore all changed stuff
back by hand (eventualy looking at object-state's history). But this
assumes short editing/single
u'd better edit a new copy and on save copy all back into original
then commit that one, on cancel abandon the new one (but beware of
m2m relations if u have them).
all else isn't safe/nice IMO.

this direct yourmodels.DateType replacement would work if u had that in some
separate file, and all your models imported from that one. But, as there's
probably lots of other code and the import DateTime is probably everywhere, i
dont think u know which DateTime's to be replaced and which not.
and what is the query that goes "plop"? and whereabouts in the code?
u can use sys.setrecursionlimit( x) to eventualy move the threshold

if the m2m is implicit, u can use it as plain relation for joins etc;
except that .has becomes .any and == becomes .contains

how about a group of objects? say whole island in the dependency
graph?

You received this message because you ar
object-query or plain query?
- objects are .. whatever class it is;
print the i.__dict__ or str(i) or whatever
- plain-sql-query ones are RowProxy, they
have i.keys() i.items() i.values()

afaiknow these traits are like my own static_types, i.e. descriptors
holding metadata and applying it to attribute access.
i have been combining SA with static_type for more than 2 years now,
since SA 3.0.
The approach i did in the beginning was to replace the object's
__dict__ by something sm
it cannot find Member class.
do u have two or more declarative_bases? u should have just one.
and i would put all these as direct class references instead
of "strings".

so u have a member, pointing to member_profile, pointing to all its
attributes into separate tables?
one way IMO is to map all other 50 tables into simple classes, then
have member profile reference each of them, i.e. relation( ..
uselist=False). Then, if u need all of them at once, request a
only the class owner of the identity sets it, internaly.
i your case Input has no separate identity, but this does not give u right to
set identity manualy. if it had, a=Input( whatver) would set that.
or that's how i get it.

there has been a number of apps announced that do html forms from SA

that sess.fulsh() in the middle there... if u move it up/down/out,

theoretically - this might make a+b+c+d look like a+(b+(c+d)). Which
isn't that bad, except that SA does not level-indent parenthesised
expressions, and the sql is going to look like lisp program... but
yes, u're right, SA relies on some python precedence and
associativity being same as SQL on
i have recently stumbled on similar - the rowproxy's __hash__ was
missing. so i have to tuple() them before usage.
Then there was Mike's question, what should the RowProxy emulate?
the tuple of the row, or something else?

i'm asking out of sheer curiosity, although it may turn more serious.
is there any known work about linking somehow SQLAlchmey and
gogole-stuff?
i looked at the google api/lang and they seem somewhat similar to
sqlalchemy's (well, like rdf-Alchemy is).
i might bite the idea of having db
