I'm looking for writing plugins (stevedore) for my application, all plugins
are new python modules and can create some entry|columns|table in the
application database, I want to manage migration by plugins|modules
Im just trying to empties a one to many records by doing this:
load.commodities = []

IntegrityError: (IntegrityError) null value in column load_id violates

Hey Michael,
I really appreciate all that, it was extremely informative. For the
academic sake I have this
extrapolated to include all the actual intermediate tables that TableB
would include.
For the academic sake, without the mixin and proxy, given a traditional
approach where TableA
is
