Add validation support to Plain Old Ruby Objects.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install validus
Include this module in a target class and override the
validate method. Use
valid? to perform the validation.
require "validus" class Person include Validus attr_accessor :name, :age def initialize @name = '' @age = 0 end def validate errors.add(:name, 'cannot be blank') if name == '' errors.add(:age, 'must be greater than 0') if age <= 0 end end person = Person.new person.valid? # => false person.errors.for(:name).to_a # => ['cannot be blank'] person.errors..to_a # => ['name cannot be blank', 'age must be greater than 0'] person.name = 'John' person.age = 20 person.valid? # => true person.errors.empty? # => true
