Rails Admin Nestable

Reorganise model data with a drag and drop tree/list structure.

Installation

To enable rails_admin_nestable, add the following to your Gemfile:

gem "rails_admin_nestable", git: "git://github.com/dalpo/rails_admin_nestable.git"

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 each model
    nestable do
      visible do
        [NavNode, Product].include? bindings[:abstract_model].model
      end
    end
  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. 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

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

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
