Hi, given a data model like this:
membership belongs_to user
membership belongs_go group
user has_many memberships
user has_many groups through memberships
group has_many memberships
group has_many users through memberships
What’s the most elegant way of setting a new collection of users as
members in a group? Anything better than:
group.memberships.clear
group.users << my_new_users
In a normal has_many relationship, you can do group.users =
my_new_users, but that doesn’t “go through”.
Br.
