我刚开始学习 PHP 和 Laravel 7，没有任何经验。我认为 Artisan 和我遇到了一些信任问题，我不知道为什么。:) 我达到了播种步骤，但我遇到了一个错误，我需要您的专业知识以简单的方式解决。以下是我在遇到此问题之前执行的先前步骤。
我创建产品控制器和模型
php artisan make:model Product -m -c -resource
数据库
class CreateProductsTable extends Migration
{
public function up()
{
Schema::create('products', function (Blueprint $table) {
$table->id();
$table->string('name', 100);
$table->string('image')->nullable();
$table->string('type');
$table->decimal('price', 2);
$table->text('description')->nullable();
$table->timestamps();
});
}
public function down()
{
Schema::dropIfExists('products');
}
}
模型
class Product extends Model
{
protected $table = 'product';
protected $fillable = ['name', 'image', 'type', 'price', 'description'];
}
控制器
class ProductController extends Controller
{
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
$product = DB::table('products')->get();
}
}
应用服务提供者
class AppServiceProvider extends ServiceProvider
{
public function register()
{
Schema::defaultStringLength(191);
}
}
之后，我创建了ProductTableSeeder
php artisan make:seeder ProductTableSeeder
class ProductTableSeeder extends Seeder
{
public function run()
{
Product::insert([
'name' => 'iphone',
'type' => 'smart phone',
'price' => 1000.98,
'description' => 'Cillum sint dolore sint labori',
]);
Product::insert([
'name' => 'Galaxy',
'type' => 'tablets',
'price' => 2000.50,
'description' => 'Cillum sint dolore sint labori',
]);
Product::insert([
'name' => 'Sony',
'type' => 'TV',
'price' => 3000,
'description' => 'Cillum sint dolore sint labori',
]);
}
}
然后，叫播种机
class DatabaseSeeder extends Seeder
{
public function run()
{
// $this->call(UserSeeder::class);
$this->call(ProductTableSeeder::class);
}
}
然后，composer dump-autoload
最后，输入播种命令后
php artisan migrate:fresh --seed
我不断收到以下错误。
