Book

• [rails] Crafting Rails 4 Applications

  • chapter2: Building Models with Active Model
    • Adding Attribute Methods
      • include ActiveModel::AttributeMethods 1) attribute methods behavior
      • attribute_method_prefix 'clear_' 2) clear_ is attribute prefix
      • define_attribute_methods(names) 3) Ask to define the prefix methods for the given attribute names
      • def clear_attribute(attribute) 4) Since we declared a “clear_” prefix, it expects to have a “clear_attribute” method defined, which receives an attributen ame and implements the clearing logic.
    • Aiming for an Active Model–Compliant API
      • include ActiveModel::Conversion
        • to_key(), to_param(), and to_partial_path()
      • extend ActiveModel::Naming
        • human(), singular()
      • extend ActiveModel::Translation
        • i18n
    • Delivering the Form
      • class_attribute :attribute_names
      • self.attribute_names = [] 1) Define a class attribute and initialize it
      • self.attribute_names += names 2) Add new names as they are defined

    • initialize set value

      def initialize(attributes = {})ttributes.each do |attr, value|
        self.public_send("#{attr}=", value)
        end if attributes
      end
      

    • Validators
      • validates_presence_of

      def validates_presence_of(*attr_names)
        validates_with PresenceValidator, _merge_attributes(attr_names)
      end
      

      const_get("#{key.to_s.camelize}Validator")

      • ActiveModel::EachValidator

      class AbsenceValidator < ActiveModel::EachValidator
        def validate_each(record, attribute, value)
          record.errors.add(attribute, :invalid, options) unless value.blank?
        end
      end
      

    • Callbacks
      • extend ActiveModel::Callbacks 1) Add callbacks behavior
      • define_model_callbacks :deliver 2) Define the callbacks. The line below will create both before_deliver, and after_deliver callbacks with the same semantics as in Active Record
      • run_callbacks(:deliver) {} Change deliver to run the callbacks
