Active Model Validations

A collection of additional validators for Active Model.

Add this line to your application's Gemfile:

And then execute:

Or install it yourself as:

$ gem install active_model_validators

class Book < ActiveRecord::Base
  attribute :pages

  validates :pages, minimum: { value: 1, message: 'must contain atleast 1 page' }
  validates :pages, maximum: { value: 1000, message: 'must not exceed 1000 pages' }
end

book = Book.new(pages: 0)
book.valid? #=> false

book = Book.new(pages: 1001)
book.valid? #=> false

book = Book.new(pages: 1)
book.valid? #=> true
