php - Laravel 5.1 - 模型工厂错误种子

Question

您好我正在尝试使用一些文章、BlogCategories、用户来填充我的数据库。

当我做“php artisan db:seed”时，我有这个错误：

[ErrorException] 传递给 Illuminate\Database\Eloquent\Factory::define() 的参数 2 必须是可调用的。给定的字符串，在第 22 行的 C:\xampp\htdocs\2016\database\factories\ModelFactory.php 中调用并定义

我在我的模型中插入了所有关系，并且我的迁移做得很好！

模型工厂.php

$factory->define(dixard\User::class, 'admin', function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->safeEmail,
        'password' => bcrypt('123'),
        'user_type' => 3,
        'remember_token' => str_random(10),
    ];
}); // line 22 

$factory->define(dixard\User::class, 'member', function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->safeEmail,
        'password' => bcrypt('123'),
        'user_type' => 1,
        'remember_token' => str_random(10),
    ];
});

$factory->define(dixard\BlogCategory::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->word,
    ];
});

$factory->define(dixard\Article::class, function (Faker\Generator $faker) {
    return [
        'title' => $faker->sentence,
        'content' => $faker->paragraph,
        'tags' => $faker->word,
        'user_id' => dixard\User::all()->random()->id,
        'category_id' => dixard\BlogCategory::all()->random()->id,
    ];
});

user_type 可以是 0（客户）、1（艺术家）、3（管理员）是一个布尔字段。

数据库Seeder.php

public function run()
    {
        Model::unguard();

        factory('dixard\User','admin', 3)->create();
        factory('dixard\BlogCategory', 5)->create();
        factory('dixard\Article', 20)->create();


        // $this->call(UserTableSeeder::class);
        $this->call(CategoryTableSeeder::class);
        $this->call(GenderTableSeeder::class);
        $this->call(ProductTableSeeder::class);
        $this->call(ColorTableSeeder::class);
        $this->call(BalanceTableSeeder::class);
        $this->call(ShippingsTableSeeder::class);
        $this->call(CouponTableSeeder::class);

        Model::reguard();
    }

感谢您的帮助！

我相信您打算使用defineAs()而不是define()前两种方法：

https://laravel.com/docs/5.1/testing §“多种工厂类型”

$factory->defineAs(dixard\User::class, 'admin', function (Faker\Generator $faker) {
        return [
            'name' => $faker->name,
            'email' => $faker->safeEmail,
            'password' => bcrypt('123'),
            'user_type' => 3,
            'remember_token' => str_random(10),
        ];
    }); // line 22 

$factory->defineAs(dixard\User::class, 'member', function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->safeEmail,
        'password' => bcrypt('123'),
        'user_type' => 1,
        'remember_token' => str_random(10),
    ];
});

Answer 2

你需要像这样重新定义你的 ModelFactory。

$factory->define(dixard\User::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->safeEmail,
        'password' => bcrypt('123'),
        'remember_token' => str_random(10),
        'user_type' = 1
    ];
});

然后在您的 DatabaseSeeder 文件中：

factory('dixard\User', 3)->create(['user_type'=>3]); // Create 3 admin users
factory('dixard\User', 3)->create(); // By default it will create 3 customer users
factory('dixard\BlogCategory', 5)->create();
factory('dixard\Article', 20)->create();

Answer 3

代替

$factory->define(dixard\User::class, 'admin', function (Faker\Generator $faker)

只需删除每个方法的“生成器”，它应该是这样的：

$factory->define(dixard\User::class, 'admin', function (Faker $faker)
