Hello all,
I need a little help, guidance to get a Many-to-Many Adjacency
Relationships, a.k.a. a dependency graph working.
Here is the short code:
metadata = MetaData('sqlite:///')
tasks_table = Table('tasks', metadata,
Column('id', Integer, primary_key = True),
Column('name',
Hello again Michael,
Have read the documentation you referenced, but am still unsure how to
now delete a Tag without generating the following error: (Note - using
Postgres in production)
(IntegrityError) update or delete on tags violates foreign key
constraint employeesTags_tag_id_fkey on
I forgot to mention, I am using SA 0.3.10.
Thanks,
Allen

More of a design question, complicated by the fact that I'm a
database neophyte (although I've used SA a fair bit).
I have a web application that with periodically connect to a
database. I've written a wrapper for the db using SQLalchemy, but I'm
unsure about the best way to use the mapped

There is an option to MySQLdb
Thanks for the feedback. I hadn't thought of doing it this way.
I did comb through the documentation a 2nd and 3rd time today though
and found the add_column() method for queries. It looks like that
may be another way to get what I want. I am thinking about even
