This bundle integrates jsTree and Gedmo Nested Set directly to Sonata Admin.
A tree builds itself in an asynchronous way. Hence, it's quite good for big trees.
SonataAdminBundle
- the SonataAdminBundle provides an installation article here:
http://symfony.com/doc/current/bundles/SonataAdminBundle/index.html
StofDoctrineExtensionsBundle
- then you need to install StofDoctrineExtensionsBundle
https://symfony.com/doc/master/bundles/StofDoctrineExtensionsBundle/index.html
Enable Tree Extension
- nested behaviour will implement the standard Nested-Set behaviour on your Entity
https://github.com/Atlantic18/DoctrineExtensions/blob/master/doc/tree.md
Install it via composer
composer require redcode/tree-bundleRegister the bundle in your app kernel ./app/AppKernel.php
class AppKernel extends Kernel
{
public function registerBundles()
{
$bundles = array(
...
new RedCode\TreeBundle\RedCodeTreeBundle(),
);
...
}
}Add the following lines to the routing file ./app/config/routing.yml
redcode_tree:
resource: "@RedCodeTreeBundle/Resources/config/routing.yml"
prefix: /adminFor the entity with enabled Gedmo Nested Set follow these steps:
Extend Admin class from \RedCode\TreeBundle\Admin\AbstractTreeAdmin
class SubjectAdmin extends AbstractTreeAdmin
{
...
}Extend AdminController from \RedCode\TreeBundle\Controller\TreeAdminController
class SubjectAdminController extends TreeAdminController
{
...
}When registering the admin as a service, you need to provide a fourth argument - the name of the field that will be shown in the tree.
