# Using validates_formatting_of is as simple as using Rails' built-in
# validation methods in models.
#
# class User < ActiveRecord::Base
# validates_formatting_of :email, :using => :email
# end
#
# If your column name is idencital to any of the built-in methods, you
# may leave off the `:using` option and validates_formatting_of will
# automatically use the validation with the matching name.
#
# class User < ActiveRecord::Base
# validates_formatting_of :email
# end
#
# You can also pass conditions and options for Rails to use
# * :if
# * :unless
# * :allow_nil
# * :allow_blank
# * :on
