RailsAdminNestedSet

Master repository has moved to gitlab, all new code will be there:

https://gitlab.com/rocket-science/rails_admin_nested_set

It looks and feels exactly like rails_admin_nestable but uses jquery Nested Sortable and awesome_nested_set or glebtv-mongoid_nested_set instead of Nestable and Ancestry.

Works with glebtv-mongoid_nested_set and awesome_nested_set.

Bonus features:

• special case support for enabled column with rails_admin_toggleable
• special case support for cover and image columns

Installation

Add this line to your application's Gemfile:

gem 'rails_admin_nested_set'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_admin_nested_set

Usage with rails_admin

Add the nested_set action for each model or only for models you need

RailsAdmin.config do |config|
  config.actions do
    ......
    nested_set do
      visible do
        %w(Page).include? bindings[:abstract_model].model_name
      end
    end
  end
end

In model:

acts_as_nested_set
rails_admin do
    ...
    nested_set({
        max_depth: 1,
        toggle_fields: [:enabled],
        thumbnail_fields: [:image, :cover],
        thumbnail_size: :thumb,
        thumbnail_gem: :paperclip, # or :carrierwave
        scopes: [:enabled, :disabled] # filter nodes by scope
    })
end
