I don't know if you did it already Luciano, but did you consider *at
least* having a look at other relationship code like
schoolbell.relationship whitch is pretty straight forward to glue in
your code than zc.relationship?
This was one of the main reasons and my point of using a package that
provide the same behavior with less code rather than pluging a very
powerfull relationship API such as zc.relationship.
To be clear: I have nothing against zc.relationship. The point is that
when I need to decide for some feature in a given project, I evaluate
a lot of different code before creating my own code.
zc.relationship is so powerfull and so low level that I couldn't
manage to get a conventional way for implemeting this in my code.
In Kirby for example, you need to decide for a package that provide
such behavior and I just wanted to hear from you, your impressions
about zc.relationship.
