ruby - Remove element from array unless has a certain value in Rails -

i have array of "names" , display current user's name if there name in array. if there other names in array, don't want show current user's name.

currently, listing names , excluding current user's name, don't want exclude current user's name if 1 in array. hope explained okay.

my code now:

module conversationshelper  def other_user_names(conversation)      users = []     conversation.messages.map(&:receipts).each |receipts|         users << receipts.select |receipt|             receipt.receiver != current_user         end.map(&:receiver)      end     users.flatten.uniq.map(&:name).join ', '  end end 

this should work:

def other_user_names(conversation)   # users (no duplicates)   users = conversation.messages.map(&:receipts).map(&:receiver).uniq    # remove current user if there more 1 users   users.delete(current_user) if users.many?    # return names   users.map(&:name).join(', ') end 

i move first line conversation#users method.
