laravel 工厂插入外键

Question

你好所有试图提供帮助的人，

我正在尝试创建工厂文件来为我的数据库播种，但我有一个问题，我如何从已经播种的 table 中插入外键？工厂代码是在同一个文件中吗？对此有什么好的做法吗？

文件

模范用户

<?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');
   }

}

模型帐户状态

<?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');
   }
}

出厂档案：

<?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,
    ];
});

如您所见，这就是我正在尝试做的事情：Factory(App\Models\AccountStatus::class)->create()->id 但不起作用

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,
    ];
});

我在工厂看到一个大写的 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,
    ];
});

如果您有一个模型依赖于另一个模型。你可以这样做，使用回调函数来创建相关的。

像这样

$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;
       }
    ];
});

您需要记住的一件事是，如果相关（状态模型）具有依赖于父（用户模型）的模型，这将进入无限循环。
