生成模型和迁移文件

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");
  }
}

迁移文件

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("分类列表")
      ->row(function (row $row) {
        $row->column(6, $this->treeview()->render());
        $row->column(6, function (column $column) {
          $form = new form();
          $form->select('parent_id', "父类名称")->options(category::selectoptions());
          $form->text('name', __('name'));
          $form->text('description', __('description'));
          $form->number('order', '排序序号')->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);
