Module: Parse::Core::EnhancedChangeTracking

Included in:

Object

Defined in:

lib/parse/model/core/enhanced_change_tracking.rb

Overview

Enhanced change tracking for Parse::Object that provides additional _was_changed? and enhanced _was methods for after_save hooks.

This module adds _was_changed? methods that work correctly in after_save contexts by using previous_changes, while keeping normal _changed? methods intact.

Key benefits:

• _was_changed? methods work correctly in after_save hooks

• _was methods return actual previous values (not current values) in after_save

• Normal _changed? methods remain unchanged (standard ActiveModel behavior)

• Automatically detects context using presence of previous_changes

Examples:

class Product < Parse::Object
  property :name, :string
  property :price, :float

  after_save :send_price_alert

  def send_price_alert
    if price_was_changed? && price_was < price
      AlertService.send("Price increased from $#{price_was} to $#{price}")
    end
  end
end
