Sample demo available at: https://github.com/dalpo/rails_admin_nestable_demo

Gem Version Code Climate

Installation

To enable rails_admin_nestable, add the following to your Gemfile:

gem 'rails_admin_nestable', '~> 0.3.1'

Add in your config/initializers/rails_admin.rb initializer the configuration:

RailsAdmin.config do |config|
  config.actions do
    # root actions
    dashboard                     # mandatory
    # collection actions
    index                         # mandatory
    new
    export
    history_index
    bulk_delete
    # member actions
    show
    edit
    delete
    history_show
    show_in_app

    # Add the nestable action for configured models
    nestable
  end
end

Configuration

You could choose between two different configurations for your model:

1. Nestable tree:

To use this configuration, you need to organize your tree model with Ancestry or Mongoid Ancestry. Otherwise your model have to respond to the parent, arrange and children methods.

The nestable_tree methods supports the following options:

  • position_field: (symbol) default => nil
  • max_depth: (integer) default => nil
  • enable_callback: (boolean) default => false
  • scope: (symbol | proc) default => nil
  • live_update: (boolean | :only) default => true (:only is for live updating only)

In your config/initializers/rails_admin.rb initializer:

RailsAdmin.config do |config|
  config.actions do
    ...
  end

  config.model MyModel do
    nestable_tree({
      position_field: :position,
      max_depth: 3
    })
  end
end

2. Nestable list:

To use this configuration, you need a position field

The nestable_list methods supports the following options:

  • position_field: (symbol) default :position
  • enable_callback: (boolean) default => false
  • scope: (symbol | proc) default => nil
  • live_update: (boolean | :only) default => true (:only is for live updating only)

In your config/initializers/rails_admin.rb initializer:

RailsAdmin.config do |config|
  config.actions do
    ...
  end

  config.model MyModel do
    nestable_list true
  end
end

Authorization with CanCan

Sample ability:

class Ability
  include CanCan::Ability

  def initialize(user)
    user ||= User.new

    if user.admin?
      can :access, :rails_admin
      can :dashboard

      if user.role? :superadmin
        can :manage, :all
      end

      if user.role? :editor
        can :edit, :all
        can :nestable, :all
      end
    end
  end
end
