Laravel 5.2:无法找到名称为[default]的工厂 [英] Laravel 5.2: Unable to locate factory with name [default]

问题描述

我想播种数据库 当我使用

I want to seed database when I use this

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

在数据库中添加三个用户，但是当我使用

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]
无法找到名称为[默认] [app \ Comment]的工厂.

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

推荐答案

默认情况下，database/factories/ModelFactory.php文件中的代码包含laravel安装.

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),
    ];
});

因此，在将其用于播种数据库之前，需要定义一个工厂模型. 这仅使用 Faker库的实例，该实例用于生成伪造的数据来为数据库播种以执行测试.

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.

确保为注释模型"添加了类似的Modal Factory.

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

因此您的注释模型工厂将如下所示:

So your Comments Model Factory will be something like this :

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