Laravel 5.3模型工厂

Question

关于工厂的简单问题：

型号工厂：

$myarray=[
'cat1',
'cat2', 
'cat3'   
];



 $factory->define(App\Job::class, function (Faker\Generator $faker) {
        return [
            'title' => $faker->randomElement($myarray),
            'firm_id' => $faker->numberBetween($min = 1, $max = 3),
            'user_id' => $faker->numberBetween($min = 1, $max = 5),
        ];
    });

为什么不起作用？

还有一个简单的问题：能否雄辩地在工厂中传递$ myarray？

Answer 1

您需要使闭包使用您的数组，使其在其中可用:)

$myarray = ['cat1', 'cat2', 'cat3'];

$factory->define(App\Job::class, function (Faker\Generator $faker) use ($myarray) {
    return [
        'title' => $faker->randomElement($myarray),
        'firm_id' => $faker->numberBetween($min = 1, $max = 3),
        'user_id' => $faker->numberBetween($min = 1, $max = 5),
    ];
});

这是来自php docs的一些示例：） http://php.net/manual/zh/functions.anonymous.php#example-160
