Hi all,
I want to define a set of sets of dependecies. That is
I've a package that is related to a set of disjuncts, each
of them composed by a set of elements. I've written a small
example (below) but I keep getting
AttributeError: 'Clause' object has no attribute 'addElement'
I don't understand why the dynamic method addElement is no added to
the class Clause even if it declares a SQLMultipleJoin.
Moreove I'm not sure about my solution, and in particular if sqlobject
will generate two different relations for 'Depdend' and 'Suggest' that
are both declared as SQLMultipleJoin ...
thank you for your help :)
p
ps: is there a irc channel for sqlobject ?
