NestedModels

============

Until now ActiveRecord wasn't great with associations massive assignment (aka multi model forms handling).

This plugin allow to deal with this kind of problems.

Example

=======

class Project < ActiveRecord::Base

  has_many :tasks, :accessible => true

end

# CREATE

project = Project.create :name => "NestedModels", :tasks => [

  { :name => "Implement", :description => "Implement me" }

]

project.name # => "NestedModels"

project.taks.size # => 1

# UPDATE

project.update_attributes :tasks => [

  { :id => 1, :name => "Implement me" },

  { :name => "Evangelize", :description => "Tell to your friends!" }

]

project.tasks.size # => 2

project.tasks.first.name # => "Implement me"

project.tasks.last.name # => "Evangelize"

# DESTROY

project.update_attributes :tasks => [

  { :id => 1, :destroy => true }

]

project.tasks.size # => 1

Note: you can define your own destroy flag:

class Milestone < ActiveRecord::Base

  set_accessible_association_destroy_flag "destroy_me"

end

project.update_attributes :milestones => [

  { :id => 1, :destroy_me => true }

]
