Defined in:

Overview

ActiveModel validation adapter.

This is the default adapter that converts JSON Schema constraints into ActiveModel validations. It provides the same validation behavior as the original EasyTalk::ValidationBuilder.

Examples:

Using the ActiveModel adapter (default)

class User
  include EasyTalk::Model

  define_schema do
    property :email, String, format: 'email'
  end
end

user = User.new(email: 'invalid')
user.valid? # => false
user.errors[:email] # => ["must be a valid email address"]
