Duplicate Action for ActiveScaffold

Currently, this gem is compatible with ActiveScaffold >= 3.3.x gems and rails >= 4.0.
Use 1.0.x for rails >= 3.x versions.

This gem adds an action to clone records. By default will only set attributes and belongs_to associations. You must override initialize_dup in your model or define a method to clone the record and set in conf.duplicate.method.

You’ll need at least ActiveScaffold 3.3.x to use this, and rails 3.x

gem install active_scaffold_duplicate

Override initialize_dup in the model to set some attributes or copy associations:

# app/models/bill.rb
class Bill < ActiveRecord::Base
  belongs_to :customer
  has_many :items
  
  def initialize_dup(other)
    super
    self.items = other.items.map(&:dup)
  end
end

Add duplicate action.

class BillsController < ApplicationController
  active_scaffold do |conf|
    conf.actions << :duplicate
  end
end

Change method to :get in link if you want to display create form instead of cloning record. Set position to :replace or :after for inline display, or enable page rendering.

class BillsController < ApplicationController
  active_scaffold do |conf|
    conf.duplicate.link.method = :get
    conf.duplicate.link.position = :after
    #conf.duplicate.link.page = true # for new page rendering
  end
end

Also you can change it globally.

class ApplicationController < ActionController::Base
  active_scaffold.set_defaults do |conf|
    conf.duplicate.link.method = :get
    conf.duplicate.link.position = :after
    #conf.duplicate.link.page = true # for new page rendering
  end
end

You can access to record which is being duplicated in your form overrides with @old_record variable.

If you use :post method, you can enable refresh_list to refresh the list instead of only adding new record at top, or set action_after_clone to open edit form for example:

  conf.duplicate.refresh_list = true
  conf.duplicate.action_after_clone = :edit

It’s possible to define some methods to add some custom code which require access to session or request params:

• For :post method, before_duplicate_save(record) and after_duplicate_save(record) can be defined, which will be called before and after saving the record respectively.
• For :new method, before_duplicate_new(record) can be defined, which will be called before rendering.
