Question

使用faker生成性别的最佳方式是什么，生成了一个名称，以便性别与名称相匹配

 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

查看文档以及他们的Github问题部分提出的问题，您的解决方案似乎是最好的。某些方法允许您为名称指定性别，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。

方法 randomElements 将返回一个包含单个元素的数组，所以如果你真的想要得到女性的话。 o＆＃39;男性＆＃39;，不要忘记在第一行末尾添加： [0] 。您需要结果数组的第一个元素（索引0）（只有一个元素）。
```
$gender = $faker->randomElements(['male', 'female'])[0];
```

还有一件事。为了准确获取您想要的内容，您需要使用 firstName 而不是名称。这样，名字将根据性别而定。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')
];

最后一件事：如果你使用男性＆＃39;而且＆＃39;女性＆＃39;而不是男性＆＃39;并且＆＃39;女性＆＃39;，不会工作!!

Answer 3

没有额外的变量就这样做，就像这样做

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

希望有所帮助

实际上，所有答案对我来说都不是很有效。它只返回女性或男性。我有几乎相同的问题。我需要三种性别中的随机元素。它总是给我这个错误信息：

 Illuminate\Database\QueryException  : Array to string conversion (SQL: insert 
 into `users` (`name`, `gender`, `email`, `admin`, `author`, `password`, 
 `remember_token`) values (Margaret Robel I, male, azieme@example.com, 1, 0, 
 dummylogin, gwKdVN7zYv))

看过Faker v.1.8.0的文档

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 ⚧
