    3.9. The validates_numericallity_of helper

    +

    This helper validates that your attributes have only numeric values. By default, it will match an optional sign followed by a integral or floating point number. Using the :integer_only option set to true, you can specify that only integral numbers are allowed.

    +

    If you use :integer_only set to true, then it will use the /\A[+\-]?\d+\Z/ regular expression to validate the attribute's value. Otherwise, it will try to convert the value using Kernel.Float.

    +
    +
    +
    class Player < ActiveRecord::Base
+  validates_numericallity_of :points
+  validates_numericallity_of :games_played, :integer_only => true
+end
+
    +

    The default error message for validates_numericallity_of is "is not a number".
