渴望加载多个关系

Question

我与模型具有以下关系

---

  class order
  {
  public function finances()
  {
    return $this->belongsTo(Finance::class,'finance_id');
  }
  }
  class Finance
  {
   public function prices()
   {
      return $this->hasMany(Price::class, 'finance_id');
   }
public function latestPrice()
{
    return $this->hasOne(Price::class,'finance_id')->latest();
}

public function orders()
{
    return $this->hasMany(Order::class, 'finance_id');
}

}

我执行此查询时

$orders = Order::with(['finances.prices.latestPrice'])->get();  

我收到此错误。调用模型[App \ Price]上未定义的关系[latestPrice]。

您必须遵守laravel的语法，请检查documentation：

$orders = Order::with(['finances.prices', 'finances.latestPrice'])->get();
