在我的代码中,每个公司都属于一个包,并且有一个包的用法

protected $fillable =[
    'name',
    'daily_cv_view',
    'monthly_cv_view',
    'per_job_post_cv_view',
    'active_job_post_limit',
    'question_per_job_post_limit',
    'package_lifetime',
    'job_post_lifetime_limit',
    'price'
    ];
public function companies()
{
    return $this->hasMany('App\Models\Company');
}

public function packageUsages()
{
    return $this->hasMany('App\Models\package_usage');
}

 public function package()
    {
        return $this->belongsTo('App\Models\Package', 'package_id');
    }

packageUsage模型

public function company()
    {
        return $this->belongsTo('App\Models\Company');
    }
    public function package()
    {
        return $this->belongsTo('App\Models\Package');
    }

在我的数据库种子,我试图建立一个软件包为每个公司创建。所以它看起来是这样的:

 $companies=factory(App\Models\Company::class, 20)->create()->each(function ($company) {
            $company->users()->save(factory(App\Models\User::class)->make());
            $company->events()->save(factory(\App\Models\Event::class)->make());
        });
        foreach ($companies as $company)
            $company->packageUsages()->save(factory(\App\Models\PackageUsage::class)->make([
                'company_id'=>$company->id,
                'package_id'=>$company->first()->package_id
            ]));

最后,我的包装用法是这样的:

$factory->define(App\Models\PackageUsage::class, function (Faker $faker) {
    $companyId= $faker->randomElement(\App\Models\Company::all()->pluck('id')->toArray());
    $company= App\Models\Company::find($companyId);
    $package=$company->package;
    $dailyCvView=$package->first()->daily_cv_view;
    return [
        'company_id'=>$company,
        'package_id'=>$package,
        'daily_cv_view'=>$faker->numberBetween($min=0 , $max=$dailyCvView ),
        'monthly_cv_view'=>$faker->numberBetween($min=$dailyCvView , $max=$package->monthly_cv_view ),
        'active_job_post_count'=>$company->jobPosts->count(),
        'expiration_date'=>$faker->dateTimeBetween($min='now', $max='+ 30 days')
    ];
});

公司工厂:

$factory->define(\App\Models\Company::class, function (Faker $faker) {
        return [
        'name'=>$faker->company,
        'company_size'=>$faker->randomElement(['10','50','100','200']),
        'slogan'=>'Ø¨Ø§ÙØ§ Ú©Ø§Ø± Ú©ÙÛØ¯',
        'website'=>$faker->domainName,
        'logo'=>'/images/companies/avatar',
        'message_title'=>'ÙØ§ Ø¯Ø± Ø§ÛÙØ¬Ø§.....',
        'message_content'=>$faker->paragraph('10'),
        'main_photo'=>'/images/companies/mainphotos/avatar',
        'about_us'=>$faker->paragraph('10'),
        'why_us'=>$faker->paragraph('10'),
        'recruiting_steps'=>$faker->paragraph('10'),
        'address'=>$faker->address,
        'email'=>$faker->safeEmail,
        'phone_number'=>$faker->numberBetween(10,100),
        'location'=>$faker->city,
            'package_id'=>$faker->randomElement(\App\Models\Package::all()->pluck('id')->toArray())
    ];
});

当我运行此命令时,它返回错误:

   Illuminate\Database\QueryException  : SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`balatar`.`package_usages`, CONSTRAINT `package_usages_package_id_foreign` FOREIGN KEY (`package_id`
) REFERENCES `packages` (`id`)) (SQL: insert into `package_usages` (`company_id`, `package_id`, `daily_cv_view`, `monthly_cv_view`, `active_job_post_count`, `expiration_date`, `updated_at`, `created_at`) values (4, 4, 12, 484, 0, 2018-09-16 07:26:11, 2018-08-30
 03:45:22, 2018-08-30 03:45:22))

当我检查数据库时,我看到它为每个包创建了3个包,公司id和包id是相同的。因为我认为对于第四个,当它试图用4个id构建它时,我只插入了3个包,一个外键失败了。我的代码有什么问题?

我认为你的第一个错误是在数据库设计上。贵公司将有多个软件包,据我所知,当时只有一个有效的软件包。所以它需要在你的 companies 和 packages

Schema::create('rel_company_package', function (Blueprint $table) {
    $table->increments('id');
    $table->timestamps();
    $table->unsignedInteger('package_id');
    $table->unsignedInteger('company_id');
    $table->timestamp('activated_at')->nullable();
    $table->timestamp('expires_at')->nullable();
    $table->boolean('is_active')->nullable();
    $table->unsignedInteger('nubmer_of_remaining_job_posts');
});

激活日期:贵公司激活其软件包的日期。
剩余职位的数量:首先来自你的数据包,一旦你的公司发布了一个职位,就会减少一个。

注:请填写 activated_at , expires_at is_active 一旦决定激活包,就立即使用正确的值。

你也应该填写 nubmer_of_remaining_job_posts

你决定播种的是生产时间上的日志数据,你可能不依赖它,因为它很容易变得庞大,需要大量的资源来计算你想要的。顺便说一句,日志数据( PackageUsage )应该保持你的数据透视表( rel_company_package ) id .

让我们直接回到您的错误:

首先在你的 company factory package usage factory 是),最好不要这样做,而是让MySQL为您随机挑选一个

$company = $\App\Models\Company::query()->inRandomOrder->first();
// and use $company->id

对于随机包装:

$package = \App\Models\Package::query()->inRandomOrder()->frist();
// and use $package->id

包装使用 实例如下:

$company->packageUsages()->save(factory(\App\Models\PackageUsage::class)->make([
    'package_id' => $company->first()->package_id
]));

company_id 再一次。你好像错过了比赛 packageUsages() 方法来自 Company 模型,它应该像:

public function packagesUsage() 
{
    return $this->hasMany('\App\Models\PackageUsage', 'company_id')
}

可能是你换的打字错误 comapny_id 具有 package_id .

但正如我一开始提到的,你最好先修好你的结构。
