Laravel 5.2：无法找到具有名称的工厂 [默认]

发布于04月05日

I want to seed database when I use this

 public function run()
{
    $users = factory(app\User::class, 3)->create();
}

Add three user in database but when I use this

 public function run()
{
    $Comment= factory(app\Comment::class, 3)->create();
}

显示错误

[InvalidArgumentException]
Unable to locate factory with name [default] [app\Comment].

推荐答案

By default the laravel installation comes with this code in the database/factories/ModelFactory.php File.

$factory->define(App\User::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->email,
        'password' => bcrypt(str_random(10)),
        'remember_token' => str_random(10),
    ];
});

So you need to define a factory Model before you use it to seed database. This just uses an instance of Faker Library which is used to generate fake Data for seeding the database to perform testing.

Make sure You have added a similar Modal Factory for the Comments Model.

因此，您的注释Model Factory将如下所示:

$factory->define(App\Comment::class, function (Faker\Generator $faker) {
    return [
        'comment' => $faker->sentence,
         // Any other Fields in your Comments Model 
    ];
});
