Comparing an array of users to an array of structs with user object as attribute, and returning matc
- by keruilin
I have an array of users who are friends. Let us call this array:
friends
I then have an array of structs. Each struct has a user object as an attribute (it also has a rank attribute). Here's what the struct class looks like, to add some context:
class Leader < Struct.new(:rank, :user); end
Let us call this array of structs:
all_leaders_plus_rank
I want to compare friends and all_leaders_plus_rank, and add the match from all_leaders_plus_rank to a new array of structs called friendly_leaders.
