具有动态属性

Question

我正在尝试使用相关图像播种用户。每个用户最多可以拥有5张图片。图像表的位置字段是0-4的整数。

有我的代码：

factory(App\User::class, 50)->create()->each(function($user) {
    $user->images()->saveMany(factory(\App\Image::class, rand(2, 5))->make());
});


$factory->define(Goods\Image::class, function(Faker\Generator $faker) {

    return [
        'id'            => $faker->unique()->uuid,
        'position'      => ????
    ];
});

如何设置其值将从0-4增加的位置值（根据图像编号）。

我也试过这个，但位置一直保持为0：

factory(App\User::class, 50)->create()->each(function($user) {
    $position = 0;
    $user->images()->saveMany(factory(\App\Image::class, rand(2, 5))->make([
        'position' => $position++
    ]));
});

尝试某事：

$position = 0;
factory(App\User::class, 50)->create()->each(function($user) {
    $user->images()->saveMany(factory(\App\Image::class, rand(2, 5))->make([
        'position' => $position++
    ]));
});
