Rails plugin that provides a
validates_ip_format_of method to
ActiveRecord models. IPs are validated by regexp.
Tests are run on all versions listed.
After installing the plugin, it's used like
class User < ActiveRecord::Base validates_ip_format_of :dhcp, :allow_nil => true, :message => 'is completely unacceptable' end
Takes the same arguments as
except for the
Please note that the regexp used to validate IPs is not perfect, but hopefully good enough. See the test suite. Patches are very welcome.
Limitations and design choices
Does not handle IPv6.
By design, the plugin does not allow RFC 1918 IPv4 addresses, e.g., 10.0.0.0, 172.16.0.0, 192.168.0.0, from being input. Also, prevents 127.0.0.1 and 0.0.0.0.
