This gem gives every ActiveRecord::Base object the possibility to do a deep clone. It is a rails3 upgrade of the deep_cloning plugin (github.com/openminds/deep_cloning).
-
Activerecord, tested with Rails 3.
-
Install by adding the gem to your Gemfile
gem ‘deep_cloneable’
-
Rails 2:
gem install deep_cloneable
And include the gem in your apps config
config.gem 'deep_cloneable'
-
Or install as a plugin if you must:
./script/plugin install git://github.com/moiristo/deep_cloneable.git
pirate.clone :include => :mateys
pirate.clone :include => [:mateys, :treasures]
pirate.clone :include => {:treasures => :gold_pieces}
pirate.clone :include => [:mateys, {:treasures => :gold_pieces}]
A dictionary ensures that models are not cloned multiple times when it is associated to nested models. When using a dictionary, ensure recurring associations are cloned first:
pirate.clone :include => [:mateys, {:treasures => [:matey, :gold_pieces], :use_dictionary => true }]
If this is not an option for you, it is also possible to populate the dictionary manually in advance:
dict = { :mateys => {} } pirate.mateys.each{|m| dict[:mateys][m] = m.clone } pirate.clone :include => [:mateys, {:treasures => [:matey, :gold_pieces], :dictionary => dict }]
pirate.clone :except => :name
pirate.clone :except => [:name, :nick_name]
pirate.clone :include => :parrot, :except => [:name, { :parrot => [:name] }]
-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
