Hi all. Probably old hat to some of you (actually I'm hoping that it is), but I'm needing a solid little snippet illustrating/representing a blurb I found in a Transfer group post from back in July. The scenario is that I have two tables who have a many to many relationship... users to preferences. I edit the preferences for a given user and want to update the junction table's records (remove the ones that are now irrelevant, leave the good ones alone, add ones not currently in existence). I understand that Transfer can automagically do such things for me, but I can't seem to find the right button to push. Anywho, here's the blurb I'm referring to:
"If you have the collection from one object -> another Why not just loop around your collection of objects, and then do a check - if it's meant to be there, keep it, if it's not,delete it,and if it's not there, add it. Doesn't seem like that big an issue. If you are using m2m, then it manages this for you. " If my hungry little eyes could see just one simple example of this "not so big issue" in action, I would be MOST greatful! :) Hypotheticals and non-tested snippets welcome.
