推荐答案

默认情况下，laravel 安装在 database/factories/ModelFactory.php 文件中带有此代码.

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

$factory->define(AppUser::class, function (FakerGenerator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->email,
        'password' => bcrypt(str_random(10)),
        'remember_token' => str_random(10),
    ];
});

因此您需要先定义一个工厂模型，然后再使用它来为数据库做种.这只是使用 Faker Library 的一个实例，它用于生成假数据以播种数据库以执行测试.

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.

确保您已为评论模型添加了类似的模态工厂.

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

所以你的评论模型工厂将是这样的:

So your Comments Model Factory will be something like this :

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