Question

我试图像这样尝试种子数据库：

factory(App\User::class, 1)
    ->create()
    ->each(function($u) {
        $role = factory(App\Role::class)->create();
        $u->role()->save( $role );
    });

这些是我的模型工厂：

$factory->define(App\User::class, function (Faker\Generator $faker) {
    return [
        'name' => 'Jakub Kohout',
        'email' => 'test@gmail.com',
        'password' => bcrypt('Uchiha'),
        'role_id' => 1
    ];
});

$factory->define(App\Role::class, function (Faker\Generator $faker) {
    return [
        'role_name' => 'Admin',
    ];
});

但我收到了这个错误：

Undefined property: Illuminate\Database\Eloquent\Builder::$orders

我做错了什么？

可悲的是，每个功能都不适用于单个元素。您必须创建多个模型才能使用每个函数：

factory(App\User::class, 2)->create()->each(function($u) {
    $role = factory(App\Role::class)->create();

    $u->role()->save( $role );
});

如果只创建了一个元素，则直接返回实例而不是集合。

这适用于您的情况：

$user = factory(App\User::class)->create();

$role = factory(App\Role::class)->create();

$user->role()->save( $role );
