Question

我有这个模型工厂生成新的联系人，它使用随机company_id：

$factory->define(App\Models\Contact::class, function (Faker\Generator $faker) 
{
    $company_id = Company::all()->random()->id;

    return [
        'firstname' => $faker->firstName,
        'lastname' => $faker->lastName,
        'phone' => $faker->phoneNumber,
        'email' => $faker->email,
        'company_id' => $company_id,
        'lead_id' => \App\Models\Lead::where('company_id', $company_id)->get()->random()->id,
    ];
});

我在种子中使用它是可以的：

factory(App\Models\Contact::class)->create();

但是为了测试，我需要以某种方式将$company_id传递给工厂，为具体的company_id创建联系人（我知道我可以->create(['company_id', $company_id])）但这只会重写来自Contact的company_id。

当我选择lead_id时，我还需要知道当前company_id。

如何将company_id作为参数传递给工厂？

Answer 1

尝试使用此示例：

$factory->define(App\Models\Contact::class, function ($faker, $params) {
    $company_id = $params['company_id'];
    ....
});

这是一个新对象：

$newContact = factory(App\Models\Contact::class)->make(['company_id' => $current_company_id]);

取决于您的Laravel版本，它会有所不同。

对于laravel 5.1 https://github.com/laravel/framework/issues/9245

您将需要检查是否手动传递

// Testcase 
$company = factory(App\Models\Company::class)->create(); 
factory(App\Models\Contact::class)->create(['company_id' => $company->id]);

// Factory
$factory->define(App\Models\Contact::class, function (Faker\Generator $faker, $attribues) {

    // Manually check if id is passed 
    $company_id = (isset($attribues['company_id'])) ?: Company::all()->random()->id;

    return [
        'firstname' => $faker->firstName,
        'lastname' => $faker->lastName,
        'phone' => $faker->phoneNumber,
        'email' => $faker->email,
        'company_id' => $company_id,
        'lead_id' => \App\Models\Lead::where('company_id', $company_id)->get()->random()->id,
    ];
});

对于Laravel 5.2及更高版本，您只需传递id https://laravel.com/docs/5.5/database-testing#relationships

// Testcase 
$company = factory(App\Models\Company::class)->create(); 
factory(App\Models\Contact::class)->create(['company_id' => $company->id]);

// Factory
$factory->define(App\Models\Contact::class, function (Faker\Generator $faker, $attribues) {

    // Manually check if id is passed 
    $company_id = (isset($attribues['company_id'])) ?: Company::all()->random()->id;

    return [
        'firstname' => $faker->firstName,
        'lastname' => $faker->lastName,
        'phone' => $faker->phoneNumber,
        'email' => $faker->email,
        'company_id' => function(){
             return factory(\App\Models\Company::class)->create()
         },
        'lead_id' => \App\Models\Lead::where('company_id', $company_id)->get()->random()->id,
    ];
});

因此，对于您的情况，请先获取随机的company_id并将其传递给工厂。取决于您的Larval版本，更改ContactModel工厂。或者，如果您有可以查询的关系，也可以这样做。

// If you have a relation 
$contact = factory(App\Models\Contact::class)->create(); 

$company_id = $contact->company->id;

Laravel使用带参数
