获得table个关系

Question

我有以下 eloquent 电话：

\App\Models\AwardRecommendation::with('entities', 'countries')->get();

当我用'countries'请求时是因为'entities'table有country_id而不是'awards'table.

我有的型号是：AwardRecommendation、Entity、ErnySans\Laraworld\Models\Countries

我想做的是在查询中获取国家/地区数据，但在 return 响应中我只得到：

0 => array:27 [▼
"id" => 1
"guid" => "268f1080-67f3-48e5-844d-96b8c09c339b"

    "pivot" => array:1 [▼

    ]
  ]
]
"countries" => null

如何使用 Laravel Eloquent 完成此操作？

在此先感谢您的帮助

Answer 1

您需要先在Entity模型中定义关系：

public function country()
{
    return $this->belongsTo(ErnySans\Laraworld\Models\Countries::class);
}

并确保 ErnySans\Laraworld\Models\Countries 是 Countries 模型的正确完整 class 名称。

然后加载与相关实体和每个实体所在国家/地区的奖励建议：

AwardRecommendation::with('entities.country')->get();

获得table个关系
