Laravel-8 ，調用未定義函數 Database\Seeders\table()

Question

運行此命令php artisan db:seed時出現此錯誤：“調用未定義函數 Database\Seeders\table()”屏幕截圖： db 播種錯誤

由於我是 laravel 的新手，在搜索各種示例后，我無法修復代碼的錯誤。我通過php artisan make:model ServiceCategory -m命令創建了一個模型，該命令創建了這個模型 ServiceCategory.php ：

    <?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class ServiceCategory extends Model
{
    use HasFactory;
}

並且還創建了一個遷移 2022_07_20_200919_create_service_categories_table.php 文件：

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('service_categories', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('slug')->index();
            $table->string('image'); 
            $table->timestamps();
        });
    }

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

然后我創建了一個播種機名稱：ServiceCategorySeeder.php：

<?php

namespace Database\Seeders;

// use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;

class ServiceCategorySeeder extends Seeder
{
    
    public function run()
    {
        DB:table('service_categories')->insert([
            [
                "name"=> "AC Installation",
                "slug"=>"ac-installation",
                "image"=>"ac installation.png"
            ],
            [
                "name"=> "AC Uninstallation",
                "slug"=>"ac-uninstallation",
                "image"=>"ac uninstallation.png"
            ],
            [
                "name"=> "AC Repair",
                "slug"=>"ac-repair",
                "image"=>"ac repair.png"
            ],
            [
                "name"=> "Laundry",
                "slug"=>"laundry",
                "image"=>"laundry.png"
            ],
            [
                "name"=> "Electrical",
                "slug"=>"electrical",
                "image"=>"electrical.png"
            ],
            [
                "name"=> "Plumbing",
                "slug"=>"plumbing",
                "image"=>"plumbing.png"
            ],
            [
                "name"=> "Painting",
                "slug"=>"painting",
                "image"=>"painting.png"
            ],
            [
                "name"=> "House Shifitng",
                "slug"=>"house shifitng",
                "image"=>"house-shifitng.png"
            ],
            [
                "name"=> "Tank Cleaning",
                "slug"=>"tank cleaning",
                "image"=>"tank-cleaning.png"
            ],
            [
                "name"=> "Furniture",
                "slug"=>"furniture",
                "image"=>"furniture.png"
            ],
            [
                "name"=> "Home Deep Cleaning",
                "slug"=>"home-deep-cleaning",
                "image"=>"home deep cleaning.png"
            ],
            [
                "name"=> "Bathroom Deep Cleaning",
                "slug"=>"bathroom-deep-cleaning",
                "image"=>"bathroom deep cleaning.png"
            ]
            
            ]);
    }
}

還修改了 DatabaseSeeder.php 是：

<?php

namespace Database\Seeders;
// use Illuminate\Database\Console\Seeds\WithoutModelEvents;

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call([
            ServiceCategorySeeder::class
        ]);
    }
}

成功運行命令： composer dump-autoload我運行了導致此錯誤的命令php artisan db:seed是 ss：

提前感謝您的幫助。

在您的播種機中，您需要DB::table而不是DB:table
