Laravel faker 根据名字生成性别

Question

使用 faker 生成性别的最佳方式是什么，生成一个名称以使性别与名称相匹配

 return [
    'name' => $faker->name,
    'email' => $faker->safeEmail,
    'username' => $faker->userName,
    'phone' => $faker->phoneNumber,
    'gender' => $faker->randomElement(['male', 'female']),//the gender does not match the name as it is.
    'address' => $faker->address,
    'dob' => $faker->date($format = 'Y-m-d', $max = 'now'),
    'password' => bcrypt('secret')
    ];

Answer 1

查看文档和 Github 问题部分提出的问题，您的解决方案似乎是最好的。有些方法允许您指定名称的性别，因此您可以这样做：

$gender = $faker->randomElement(['male', 'female']);

return [
    'name' => $faker->name($gender),
    'email' => $faker->safeEmail,
    'username' => $faker->userName,
    'phone' => $faker->phoneNumber,
    'gender' => $gender,
    'address' => $faker->address,
    'dob' => $faker->date($format = 'Y-m-d', $max = 'now'),
    'password' => bcrypt('secret')
];

希望这符合您的要求。

Answer 2

要在没有额外变量的情况下做到这一点，请像这样做

return [
  'gender' => $faker->randomElements(['male', 'female']),
  'name' => $faker->name(function (array $user) {return $user['gender'];})
]

希望有帮助

1. 方法 randomElements 将返回一个包含单个元素的数组，因此如果您想获取“女性”或“男性”，请不要忘记在第一行末尾添加：[0] 。您需要结果数组（只有一个元素）的第一个元素（索引 0）。

    $gender = $faker->randomElements(['male', 'female'])[0];
   

2. 还有一件事。为了准确获得您想要的内容，您需要使用 firstName 而不是 name。这样，名字就会根据性别而定。这样做：

    return [
        'name' => $faker->firstName($gender),
        'email' => $faker->safeEmail,
        'username' => $faker->userName,
        'phone' => $faker->phoneNumber,
        'gender' => $gender,
        'address' => $faker->address,
        'dob' => $faker->date($format = 'Y-m-d', $max = 'now'),
        'password' => bcrypt('secret')
    ];
   

3. 最后一件事：如果你使用“男性”和“女性”，而不是“男性”和“女性”，这是不会起作用！！

其实所有的答案都对我来说并不真正有用。它只返回雌性或雄性。 我有几乎同样的问题。我需要从三种性别中随机选择一个元素👍😀。它总是给我这个错误消息：

 Illuminate\Database\QueryException  : Array to string conversion (SQL: insert 
 into `users` (`name`, `gender`, `email`, `admin`, `author`, `password`, 
 `remember_token`) values (Margaret Robel I, male, [e-mail], 1, 0, 
 dummylogin, gwKdVN7zYv))

查看了 Faker v.1.8.0

的文档后

这对我有用：

public function run()
{
  $faker = Faker::create();
  foreach(range(1,10) as $index){

    // Returns always random genders according to the name, inclusive mixed !!
    $gender = $faker->randomElement($array = array('male','female','mixed'));

    DB::table('users')->insert([
          'name' => $faker->name($gender),   
          'gender' => $gender,           
          'email' => $faker->unique()->safeEmail,
          'admin' => $faker->numberBetween($min = 0, $max = 1),
          'author'=> $faker->numberBetween($min = 0, $max = 1),
          'password' => 'dummylogin',
          'remember_token' => str_random(10),
    ]);
  }
}

It turns out mixed genders will always have different names, because you can 
be either way 😄⚧

接受的答案工作正常，但我们可以简化一些事情，而不必先设置变量

return [
    'first_name' => fn(array $attributes) => fake()->firstName($attributes['gender']),
    'gender' => fake()->randomElement(['male', 'female'])
],

如您所见，这样做时属性顺序并不重要

快乐编码:)
