這篇文章主要介紹了laravel-admin利用ModelTree實(shí)現(xiàn)對(duì)分類信息的管理，文中通過示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

生成模型和遷移文件

php artisan make:model Models/Shoping/Category -m

app/Models/Shoping/Category.php

<?php

namespace App\Models\Shoping;

use Encore\Admin\Traits\AdminBuilder;
use Encore\Admin\Traits\ModelTree;
use Illuminate\Database\Eloquent\Model;

/**
 *
 * Class Category
 * @package App\Models\Shoping
 */


class Category extends Model
{
  //
  use ModelTree, AdminBuilder;
  protected $table="shoping_categories";
  public function __construct(array $attributes = [])
  {
    parent::__construct($attributes);
    $this->setTitleColumn("name");
  }
}

遷移文件

class CreateCategoriesTable extends Migration
{
  /**
   * Run the migrations.
   *
   * @return void
   */
  public function up()
  {
    Schema::create('shoping_categories', function (Blueprint $table) {
      $table->increments('id');
      $table->integer('parent_id')->unsigned()->nullable();
      $table->string('name');
      $table->string('description')->nullable();
      $table->integer('order')->unsigned();
      $table->timestamps();
    });
  }

  /**
   * Reverse the migrations.
   *
   * @return void
   */
  public function down()
  {
    Schema::dropIfExists('shoping_categories');
  }
}

生成控制器

php artisan admin:make CategoriesController --model=App\Models\Shoping\Category

app/Admin/Controllers/CategoriesController.php

use App\Models\Shoping\Category;
use Encore\Admin\Controllers\AdminController;
use Encore\Admin\Form;
use Encore\Admin\Grid;
use Encore\Admin\Layout\Column;
use Encore\Admin\Layout\Content;
use Encore\Admin\Layout\Row;
use Encore\Admin\Show;
use Encore\Admin\Tree;
use Encore\Admin\Widgets\Box;

class CategoriesController extends AdminController
{

  public function index(Content $content)
  {
    return $content->title($this->title)
      ->description("分類列表")
      ->row(function (Row $row) {
        $row->column(6, $this->treeView()->render());
        $row->column(6, function (Column $column) {
          $form = new Form();
          $form->select('parent_id', "父類名稱")->options(Category::selectOptions());
          $form->text('name', __('Name'));
          $form->text('description', __('Description'));
          $form->number('order', '排序序號(hào)')->default(0);
          $column->append((new Box(trans('admin.new'), $form))->style('success'));
        });

      });

  }

  protected function treeView()
  {
    return Category::tree(function (Tree $tree) {
      $tree->disableCreate();
      return $tree;
    });
  }

添加路由

app/admin/routes.php

$router->resource('categories',CategoryController::class);
