生成模型和迁移文件，使用 PHP Artisan 命令：

phpphp artisan make:model Models/Shopping/Category -m app/Models/Shopping/Category.php

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);
