我怎样才能改进这个 if 语句？

Question

如何改进 ruby 中的 if 语句？

原始if声明：

status = 'None available', css_class = 'grey'
if pending_final > 0
  status = 'Pending'
  css_class = 'red'
elsif requested_final == 0 && request.granted
  status = 'Granted'
  css_class = 'green'
elsif requested_final == 0 && request.granted == false
  status = 'Not requested'
  css_class = 'red'
end

我试图像这样重构：

status, css_class = if pending_final > 0
 'Pending', 'red'
elsif requested_final == 0 && request.granted
 'Granted', 'green'
 # and so on...
else
 'None available', 'grey'
end

但是我在“,”逗号中遇到语法错误。

试试这个

status, css_class = if pending_final > 0
 ['Pending', 'red']
elsif requested_final == 0 && request.granted
 ['Granted', 'green']
 # and so on...
else
 ['None available', 'grey']
end
