hi.
in SA, 1:1 is represented as relation( ...uselist=False,
backref( ... uselist=False)). The question is, can that cardinality be
enforced somehow - AFAIK that backref is not a real back-link in the DB.

Maybe I'm using the 'case_sensitive' in a wrong way.
Here what I want to reach :
create unique index myname on mytable (lower(mycolumn));
How can I create it on sqlalachemy?

Trying to migrate from 0.3.10 to 0.5 I have this error:
not sure if that is the problem, but are Folder.items and
FolterContent.folder the reciprocal ends of same relation?
then u need only one of those, with backref.

I'm playing with inheritance for a CMS-like application. It's very

I think this would involve sending func.lower(table.c.somecolumn) to

how would you establish a trusted connection using straight pyodbc ?
SQLA's URL should allow any number of arguments straight through to
pyodbc, and if not, there are documented methods of giving the SQLA
engine a connection factory that does whatever is needed in order to
connect.

place a unique index on the foreign key column. though the ORM might
not know how to update this correctly - you might need a mapper
extension that nulls out the column when an old member is detached and
a new member attached.
