Ruby on Rails

Solved it like that:

abilities_array = []
roles.map(&:abilities).flatten(1).each do |e|
if i = abilities_array.find_index{|ar| ar[1]==e[1] && ar[2]==e[2]}
abilities_array[i] = e
else
abilities_array << e
end
end
abilities_array.map{|a| "#{a[0]} #{a[1]}, #{a[2]}#{", "+a[3] unless
a[3].blank?}"}
