A Simple Regex for Rails Email Validation

Here’s my quick-and-dirty Rails email regex:

/^([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})$/i

Declare the regex somewhere near the beginning of your User model, like so:

EMAIL_REGEX = /^([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})$/i

A lot of code is yet to be written. Onward!
