Validates the format of a string as a valid email address.¶ ↑

Just put in your Rails model something like:¶ ↑

class User < ActiveRecord::Base validates_email_format_of :email end

And it will take care of validate the string under ActiveRecord validations such:¶ ↑

• validates_presence_of

• validates_format_of

• validates_uniqueness_of

Plus, it includes an extra validation for avoid email-temporary domains like mailinator.com, example:¶ ↑

class User < ActiveRecord::Base validates_email_format_of :email, :invalid_domains => %w(mailmoat.com mailinator.com fakemail.com) end

With the :invalid_domains parameter, any email addresses @mailmoat.com, @mailinator.com or @fakemail.com will be rejected.¶ ↑

TODO:¶ ↑

• Make ActiveRecord validations opcionals.
