ruby - 在case语句中使用include方法

Question

我正在使用这样的东西:

case referer
      when (referer.include? "some_string")
        redirect_link = edit_product_path
      when (referer.include? "some_other_string")
        redirect_link = other_product_path
end

不幸的是,即使字符串some_string存在于变量中,它也会返回nil referer.

这是我在Ruby控制台中尝试的内容:

ruby-1.8.7-p334 :006 > jasdeep = "RAILS"
ruby-1.8.7-p334 :026 > case jasdeep
ruby-1.8.7-p334 :027?>   when (jasdeep.include? "AI")
ruby-1.8.7-p334 :028?>   puts "Hello"
ruby-1.8.7-p334 :029?> end
=> nil

任何输入将不胜感激.

Answer 1

试试这个

jasdeep = "RAILS"
case jasdeep
when /IL/
  puts "Hello"
end
