What's this?

extract_associated(association) public

Extracts a named association from the relation. The named association is first preloaded, then the individual association records are collected from the relation. Like so:

account.memberships.extract_associated(:user)
# => Returns collection of User records

This is short-hand for:

account.memberships.preload(:user).collect(&:user)
