Question

我有Users和UserProfiles。

所有Users只有一个UserProfile。

我的UserTableSeeder类正在创建25条记录，并为每条记录输出UserProfile。

由于某种原因，我在Users上获得的记录翻倍，并且在UserProfile上指定的数量增加了，所以要插入50 Users，要插入25 UserProfiles。

种子：

public function run()
    {
        factory(App\User::class, 25)->create()->each(function ($user) {
            $user->profile()->save(factory(App\UserProfile::class)->make());
        });
    }

用户类别：

class User extends Model
{

    public function profile() {
        return $this->hasOne('App\UserProfile');
    }

}

UserFactory：

$factory->define(User::class, function (Faker $faker) {
    return [
        'username' => $faker->userName(),
        'email' => $faker->unique()->safeEmail,
        'email_verified_at' => now(),
        'password' => '$2y$10$TKh8H1.PfQx37YgCzwiKb.KjNyWgaHb9cbcoQgdIVFlYg7B77UdFm', // secret
        'remember_token' => Str::random(10),
    ];
});

UserProfileFactory：

$factory->define(UserProfile::class, function (Faker $faker) {
    return [
        'user_id' => factory('App\User'::class)->create()->id,
        'bio' => $faker->paragraph()
    ];
});

UserProfile模型：

class UserProfile extends Model
{
    public function user() {
        return $this->belongsTo('App\User');
    }
}

由于所有用户都有个人资料，我的预期输出是25个用户和25个用户表

更改此代码

$factory->define(UserProfile::class, function (Faker $faker) {
    return [
        'user_id' => factory('App\User'::class)->create()->id,
        'bio' => $faker->paragraph()
    ];
});

$factory->define(UserProfile::class, function (Faker $faker) {
    return [
        'bio' => $faker->paragraph()
    ];
});

Laravel工厂/播种机创建指定的双记录
