Better data structure for multiple checks for a variable than if statements?

Question

So, I have this block of code, and yes it looks ugly. Is there a better a data structure I can use to compare row.add,row.modify,row.delete and row.query with "Y" and call the get_role function? Note this block of code runs in a loop, hence the 'row'.

    if row.add == "y"
      role_ids << get_role("c")  
    end
    if row.modify == "y"
      role_ids << get_role("u")
    end
    if row.delete == "y"
      role_ids << get_role("d")
    end
    if row.query == "y"
      role_ids << get_role("r")
    end

Thanks !

Answer 1

role_ids << case
  when row.add    == "y" then get_role("c")
  when row.modify == "y" then get_role("u")
  when row.delete == "y" then get_role("d")
  when row.query  == "y" then get_role("r")
end

Answer 2

UPDATE !

changed to

operations = [row.add,row.modify,row.delete,row.query]
crud=["c","u","d","r"]
operations.each_with_index{|operation,i| if operation == "y" then role_ids << get_role(crud[i]) end}

Answer 3

operations = { :add => "c", :modify => "u", :delete => "d", :query => "r" }
operations.each do |key,value|
  role_ids << get_role(value) if row.send(key) == "y"
end
