Hi,

I have a many to many relation between users and groups. The pivot table features a from and to fields which say, between which dates a user is in a group. That way, I can keep track, in what group a user was. For that reason, a user can relate to the same group multiple times, but for different timespans. On an eloquent model, i can use the sync() which only accepts an id once. Also attach() and detach() have an id as argument. How should I save related models then, if I cannot use mentioned methods? Only way I see right now is to omit relationship properties and use a pivot model instead and do all the syncing manually. Or do I miss something?

Thanks, Simon
