Rails 3验证IPv4和IPv6格式 [英] Rails 3 validate IPv4 and IPv6 format

问题描述

我知道IPv4和IPv6的验证格式.但不确定如何将它们组合在一起，因此至少一种格式应该是正确的.这是我的验证

I know the validation format for IPv4 and IPv6. But not sure how I can combine them so atleast one format should be true. Here is my validation

validates :src_ip_addr, :presence => true, :uniqueness => true,
            :format => { :with => Resolv::IPv4::Regex, :message => "Not an valid IPv4 format"}

  validates :src_ip_addr, :presence => true, :uniqueness => true,
            :format => { :with => Resolv::IPv6::Regex, :message => "Not an valid IPv6 format"}

我如何将它们组合在一起，因此，如果一种格式正确，则验证应该起作用.仅当ipv4和ipv6格式不正确时才会失败.

How I can combine them so if one format is correct then validation should work. Should fail only if ipv4 and ipv6 format is not correct.

谢谢.

推荐答案

您也可以将它们与Regexp.union组合:

You can also combine them with Regexp.union:

:format => { :with => Regexp.union(Resolv::IPv4::Regex, Resolv::IPv6::Regex) ...
