Multi-Attribute Sorting and Filtering on an Array of Structs

Question

I have an array of structs. Each struct has the following two attributes:

• win %
• # of wins

I want to sort the array of structs by win %; however, for only those structs with at least 3 wins.

Any suggestions?

Answer 1

First use select to take only the objects with at least 3 wins, then use sort_by to sort by the percentage:

array.select {|x| x.num_of_wins >= 3}.sort_by {|x| x.win_percent}
