Modern applications often require the ability to create copies of database hierarchies while preserving the integrity of the data. Deep Cloning provides a robust solution for Ruby on Rails applications, allowing you to trigger precise replication of database records starting from a specified model, all the way down its associations.

• Model Attributes Preservation: Deep Cloning retains all values for database columns (model attributes), ensuring data fidelity throughout the replication process.

• Association Cloning: Replicate complex hierarchies effortlessly, preserving relationships between models, just like the original.

• Customizable Cloning: Tailor the cloning process to meet your specific needs with customizable options and configurations.

• Efficiency and Performance: Deep Cloning is optimized for speed and efficiency, making it suitable for both small-scale projects and enterprise-level applications.

1. Installation: Add the Deep Cloning gem to your Rails project by including it in your Gemfile and running bundle install.

gem 'deep-cloning'

2. Trigger Cloning: To replicate a model and its associations, simply call the DeepCloning::Clone.new(@root_item, opts).replicate method on the desired model instance root item.

# @root_item should be already created and is the item to be copied
# @target_item should be already created and is the item which will receive the @root_item hierarchy children to be copied

DeepCloning::Clone.new(@root_item, opts).replicate do |source, destiny, moment|
  case moment
  when :before_save
    before_save(source, destiny)
  when :after_save
    after_save(source, destiny)
  when :skip?
    skip?(source)
  else
    destiny
  end
end

# Clone options
def opts
  {
    # Which classes do you want to copy on the hierarchy?
    including: %w[Project User City],

    # This is necessary: the id of the @root_item should point to the @target_item.
    'RootClass' => { @root_item.id => @target_item },

    # Do you want to save the root model instance?
    save_root: false
  }
end

# You can set up specific handling on the source/destiny item beforing replicating the item
def before_save(source, destiny)
  case source
  when SpecificModel
    # Do specific handlings
  end
end

# You can set up specific handling on the source/destiny item after replicating the item
def after_save(source, destiny)
  case source
  when SpecificModel
    # Do specific handlings
  end
end

# Do you want to skip the copy of an item based on a criteria?
def skip?(source)
  return true if source.is_a? User and source.age > 50
  false
end
