ruby - 无论如何我可以使用 if else inside ruby​​ case..end

Question

case search_term
when 'a'
  ptr = 0
when 'b'
  ptr = 1
when 'c' 
  ptr = 2
else
  ptr = 99
end

if location = 'xyz' and search_term = 'c'
ptr = 0
end

有什么方法可以在 case 语句中包含上面的 if 吗？

when 'c' 
  if location == 'xyz' then  #note the ==
    0 
  else 
    2
  end 
else

end
