TheSortableTree

Gem Version Code Climate

tested with rails 4.1.0rc2 + haml 4

Nested Set + Drag&Drop GUI. Very fast! Best render helper! 2000 nodes/sec. Ready for rails 4 (RubyGems)

Dummy Application

Drag&Drop GUI. Sotrable tree

Render tree

Render Nested Options

Keywords

Awesome nested set, Nested set, Ruby, Rails, Nested set view helper, Sortable nested set, Drag&Drop GUI for nested set, View helper for nested set, render tree

Install

Gemfile (Rails 3, Rails 4)

ruby gem 'awesome_nested_set' # or any similar gem (gem 'nested_set') gem "the_sortable_tree", "~> 2.5.0"

Console

ruby bundle

Using

JQuery and JavaScripts

app/assets/javascripts/application.js

Sortable GUI require JQuery libs

ruby //= require jquery //= require jquery-ui //= require jquery_ujs

Add next JS only for Sortable GUI

ruby //= require jquery.ui.nestedSortable //= require sortable_tree/initializer

Stylesheets

app/assets/stylesheets/application.css

ruby *= require tree *= require sortable_tree *= require nested_options

Extend your Routes for Sortable GUI

```ruby resources :pages do collection do get :manage

# required for Sortable GUI server side actions
post :rebuild   end end ```

manage - just page, where you want render Sortable tree.

Extend your Model

```ruby class Page < ActiveRecord::Base include TheSortableTree::Scopes

# any code here end ```

Extend your controller and find your tree

```ruby class PagesController < ApplicationController include TheSortableTreeController::Rebuild

def manage @pages = Page.nested_set.select(‘id, title, content, parent_id’).all end

# any code here end ```

Basic Render Method

ruby build_server_tree(tree, options)

Render Tree

app/views/pages/manage.html.haml

haml %ol.tree= just_tree @pages

just_tree is just alias of build_server_tree(tree, type: :tree)

Render Sortable Tree

haml %ol.sortable_tree{ data: { max_levels: 5, rebuild_url: rebuild_pages_url } } = sortable_tree @pages sortable_tree is just alias of build_server_tree(tree, type: :sortable)

Render Nested Options Tree

haml = select_tag :page_id, nested_options(@pages, :selected => Page.last), class: :nested_options

nested_options is just alias of build_server_tree(tree, type: :nested_options)

build_server_tree options

Client side:

Required params for sortable GUI! Must be defined at root element of tree.

  1. max_levels - maximum depth of nesting
  2. rebuild_url - URL to rebuild method on server side

ruby %ol.sortable_tree{ data: { max_levels: 3, rebuild_url: rebuild_pages_url } }

Server side:

define

ruby build_server_tree(pages, {:option_1 => :value_1, :option_2 => :value_2})

use

ruby options[:NAME]

Options list:

  1. id - id field of node
  2. title - title field of node
  3. type - type of tree [tree sortable nested_options]
  4. namespace - for example: :admin. [] - by default
  5. render_module - your own Render Tree Helper

Rendering runtime params (see code of render helpers):

You can use next options, when rendering run:

  1. level - level number
  2. root - root flag [true false]
  3. klass - class name
  4. has_children - has children flag [true false]
  5. children - array of children

Customization

Try to run next view generators:

Render helpers for HTML tree generation

ruby bundle exec rails g the_sortable_tree:views tree bundle exec rails g the_sortable_tree:views sortable bundle exec rails g the_sortable_tree:views nested_options

Base Render helper of gem

ruby bundle exec rails g the_sortable_tree:views helper

Assets of gem

ruby bundle exec rails g the_sortable_tree:views assets

I want to know more

  1. How to change HTML code of tree?
  2. How to create new tree HTML Builder helper?
  3. I need to render reversed tree
  4. Gem can’t correctly define a Name of your Model
  5. ChangeLog

Is it fast? Yes, it is!

BANCHMARK:

tree params: 16.000 nodes, 3 levels

  • Views: 7999.6ms ActiveRecord: 79.2ms
  • WebInspector full time ~ 9.64s

total: ~ 2000 nodes/sec

Looking for maintainers

Do you want to be open source contributor? There are some ideas:

Try to create view helpers for:

  1. Mongoid NestedSet
  2. acts_as_ordered_tree
  3. Expand tree via AJAX
  4. Comments Tree gem
  5. gem Ancestry (???)

I want to try! I need tests!

  1. I’m develop gem with test app the_sortable_tree_test_app. You can clone it and see some testcase-pages for gem
  2. Sorry, but I have not tests for this gem. Gem is so simple. It’s easy to test only with test app.
  3. You can write some tests, if your need. I will be happy certainly.
  4. No! I know RSpec. I can write tests. But I have not reasons to write tests here.
