Ruby on rails验证代码不起作用

Question

这里有错吗？我希望条目以http://amzn.com/w/开头，后跟任何内容。但是，无论我输入什么，我都会收到错误消息。

validates :wl_url, format: { with: /\A(http:\/\/amzn\.com\/w\/)+([a-z0-9]*)\z/, 
  message: 'Please make sure the Wish List code starts with http://amzn.com/w/, if unsure see "how it works" page for instructions.'}

Answer 1

试试这个语法：

validates_format_of :wl_url, :with => /\A(http:\/\/amzn\.com\/w\/)+([a-z0-9]*)\z/i, :message => "Please make sure the Wish List code starts with http://amzn.com/w/, if unsure see "how it works" page for instructions."
