laravel工廠插入外鍵

Question

大家好，他們正在努力提供幫助，

我試圖創建工廠文件來播種我的數據庫，我有一個問題，我如何從已播種的表中插入一個外鍵？ 而工廠代碼是全部在同一個文件中？ 對此有什么好的實踐？

檔

模型用戶

<?php

namespace App\Models;

use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{

  protected $table = 'user'; //name of the table in database
  protected $primaryKey = 'Id'; //Primary Key of the table

  /**
   * Relations between tables
   */
   public function GetLoginInfo()
   {
     return $this->hasMany('App\Models\LoginInfo', 'UserId');
   }

   public function getStatus()
   {
     return $this->belongsTo('App\Models\AccountStatus');
   }

}

模型帳戶狀態

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class AccountStatus extends Model
{
  protected $table = 'account_status'; //name of the table in database
  protected $primaryKey = 'Id'; //primary Key of the table
  public $timestamps = false; //true if this table have timestaps
  /**
   * Relations between tables
   */
   public function GetUsers()
   {
     return $this->hasMany('App\Models\Users', 'StatusId');
   }
}

工廠檔案：

<?php
/** @var \Illuminate\Database\Eloquent\Factory $factory */

//Factory for Account Status table
$factory->define(App\Models\AccountStatus::class, function (Faker\Generator $faker) {
    return [
      'Description' => $faker->word,
    ];
});

//Factory for user table
$factory->define(App\Models\User::class, function (Faker\Generator $faker) {
    return [
      'Username' => $faker->unique()->userName,
      'Password' => bcrypt('test'),
      'Email' => $faker->unique()->safeEmail,
      'Name' => $faker->name,
      'StatusId' => Factory(App\Models\AccountStatus::class)->create()->id,
    ];
});

這是我試圖做的，你可以看到：工廠（App \\ Models \\ AccountStatus :: class） - > create（） - > id但不工作

Answer 1

$factory->define(App\Models\User::class, function (Faker\Generator $faker) {
    return [
      'Username' => $faker->unique()->userName,
      'Password' => bcrypt('test'),
      'Email' => $faker->unique()->safeEmail,
      'Name' => $faker->name,
      'StatusId' => factory(App\Models\AccountStatus::class)->create()->id,
    ];
});

我在工廠看到一個大寫的F ..

$factory->define(App\Models\User::class, function (Faker\Generator $faker) {

     $accountStatus = factory(App\Models\AccountStatus::class)->create()

     return [
      'Username' => $faker->unique()->userName,
      'Password' => bcrypt('test'),
      'Email' => $faker->unique()->safeEmail,
      'Name' => $faker->name,
      'StatusId' => $accountStatus->id,
    ];
});

編輯（改進）

如果您有一個型號依賴於另一個型號。 你可以這樣做，使用回調函數來創建相關的。

像這樣

$factory->define(App\Models\User::class, function (Faker\Generator $faker) {
    return [
      'Username' => $faker->unique()->userName,
      'Password' => bcrypt('test'),
      'Email' => $faker->unique()->safeEmail,
      'Name' => $faker->name,
      'StatusId' => function () {
          return factory(App\Models\AccountStatus::class)->create()->id;
       }
    ];
});

您需要記住的一件事是，如果相關（狀態模型）具有依賴於父（用戶模型）的模型，這將進入無限循環。
