在 laravel 中创建数据表时出现错误

Question

有谁知道为什么我在为我的工作类别创建数据表时会收到此错误？

DatabaseSeeder.php

<?php


use Illuminate\Database\Seeder;

// Import DB and Faker services
use Illuminate\Support\Facades\DB;
use Faker\Factory as Faker;

class DatabaseSeeder extends Seeder
{
/**
 * Seed the application's database.
 *
 * @return void
 */
public function run()
{
    // \App\Models\User::factory(10)->create();

    $faker = Faker::create();

   

    foreach (range(1,150) as $index) {
        DB::table('jobs')->insert([
            'company' => $faker->company,
            'category' => $faker->category,
            'position' => $faker->position,
            'description' => $faker->description,
            'salary_from' => $faker->salary_from,
            'salary_to' => $faker->salary_to,
            'status' => $faker->status,

            
        ]);
   }
}  
}

我的错误是

 InvalidArgumentException 

Unknown formatter "category"

at C:\xampp\htdocs\job\vendor\fakerphp\faker\src\Faker\Generator.php:300
296▕                 return $this->formatters[$formatter];

298▕         }
299▕ 
➜ 300▕         throw new \InvalidArgumentException(sprintf('Unknown formatter "%s"', $formatter));
301▕     }
302▕ 
303▕     /**

1   C:\xampp\htdocs\job\vendor\fakerphp\faker\src\Faker\Generator.php:278
  Faker\Generator::getFormatter("category")

2   C:\xampp\htdocs\ob\vendor\fakerphp\faker\src\Faker\Generator.php:497
  Faker\Generator::format("category")

这是我第一次创建datatable，我是laravel的新手，所以检查后发现使用datatable生成数据要简单得多

Answer 1

您正在使用 faker 不支持的某些字段。在此处查看可用字段：https://github.com/fzaninotto/Faker。

在此处查看带有更新字段的示例：

   DB::table('jobs')->insert([
            'company' => $faker->company,
            'category' => $faker->word,
            'position' => $faker->randomDigit,
            'description' => $faker->text,
            'salary_from' => $faker->randomDigit,
            'salary_to' => $faker->randomDigit,
            'status' => $faker->numberBetween(1, 3), // Change to available statusses         
        ]);

Answer 2

类别在 faker 中不存在，而且位置（如果它意味着职位，则有职位名称），可能您还想控制类别名称，所以我会创建一个数组

   DB::table('jobs')->insert([
            'company' => $faker->company,
            'category' => $faker->randomElement(['technology', 'business','law','accounting']),
            'position' => $faker->jobtitle(),
            'description' => $faker->text,
            'salary_from' => $faker->randomDigit,
            'salary_to' => $faker->randomDigit,
            'status' => $faker->numberBetween(1, 3), // Change to available statusses         
        ]);
