我正在尝试让模型工厂工作，主要模型地点如下：

  1. 是 hasOne 关系的地方
  2. 具有 belongsTo 关系的类型

最重要的是，place 有一个名为 full_address 的函数，它返回一个逗号分隔的字符串。

场地有一个 toSearchableArray() 将自定义数据发送到 Algolia，当我运行工厂创建方法时，我得到：

PHP Error:  Call to a member function full_address() on null in  app/Venue.php on line 57

这是场地模型

class Venue extends Model
{

    use Searchable;

    public function toSearchableArray()
    {
        $type = $this->type()->first();
        $place = $this->place()->first();

        return [ 'name' => $this->name,
            'type' => $type['name'],
            'type_id' => $type['id'],
            'venue_id' => $this->id,
            'background_image' =>$type['background_file_name'],
            'full_address' => $place->full_address(),
            'slug' => $this->slug_field,
            '_geoloc' =>
                [ 'lat' => (float)$this->latitude,
                    'lng' => (float)$this->longitude
                ]
        ];
    }

    public function place()
    {
        return $this->hasOne('App\Place');
    }

    public function type()
    {
        return $this->belongsTo('App\Type');
    }

}

这些是模型工厂

$factory->define(App\Venue::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'phoneNumber' => $faker->word,
        'latitude' => $faker->latitude,
        'longitude' => $faker->longitude,
        'LatLong' => $faker->word,
        'website' => $faker->word,
        'type' => $faker->word,
        'place_id' => function () {
            return factory(App\Place::class)->create()->id;
        },
        'status' => $faker->word,
        'slug_field' => $faker->word,
        'type_id' => function () {
             return factory(App\Type::class)->create()->id;
        },
    ];
});

$factory->define(App\Place::class, function (Faker\Generator $faker) {
    return [
        'place_id' => $faker->randomNumber(),
        'administrative_area_level_2' => $faker->word,
        'administrative_area_level_1' => $faker->word,
        'country' => $faker->country,
        'postal_town' => $faker->word,
        'postal_code_prefix' => $faker->word,
        'postal_code' => $faker->word,
        'route' => $faker->word,
        'locality' => $faker->word,
        'premise' => $faker->word,
        'street_number' => $faker->word,
        'neighborhood' => $faker->word,
        'point_of_interest' => $faker->word,
        'natural_feature' => $faker->word,
        'administrative_area_level_3' => $faker->word,
        'postal_code_suffix' => $faker->word,
        'sublocality_level_1' => $faker->word,
        'subpremise' => $faker->word,
        'sublocality_level_5' => $faker->word,
        'sublocality_level_4' => $faker->word,
        'sublocality_level_2' => $faker->word,
        'sublocality_level_3' => $faker->word,
        'administrative_area_level_4' => $faker->word,
        'colloquial_area' => $faker->word,
        'long' => '123',
        'lat' => '123',
    ];
});

$factory->define(App\Type::class, function (Faker\Generator $faker) {
    return [
        'name' => $faker->name,
        'marker_file_name' => $faker->word,
        'background_file_name' => $faker->word,
        'description' => $faker->word,
        'ShortName' => $faker->word,
    ];
});

我需要做什么才能获得与场地相关的地点的参考。

谢谢
