Simple ActiveModel Validators

A collection of ActiveModel validators that don't pollute the global namespace.

List of available validators:

• SimpleActiveModelValidators::AssociatedBubblingValidator

  Bubbles up associated validation errors on to the main model. For example

  class User < ActiveRecord::Base
    validates :name, presence: true
     has_many :comments
     validates_with SimpleActiveModelValidators::AssociatedBubblingValidator,
                    attributes: [:comments]
  end
  
  class Comment < ActiveRecord::Base
    belongs_to :user
    validates :body, presence: true
  end
  
  user = User.new(name: 'Joe', comments: [Comment.new(body: '')])
  user.valid?
  user.errors.messages == { comments: ["is invalid", { body: ["can't be blank"] }] }
