Laravel 5关系问题

Question

在我的订单表中，我得到user_id和address_id两个列的关系是相同的，我可以从users表中获取信息，但不能从addresses表中获取信息！

Order型号：

public function user() {
    return $this->belongsTo(User::class);
  }

  public function address(){
     return $this->belongsTo(Address::class, 'address_id');
  }

Address型号：

public function user(){
     return $this->belongsTo(User::class);
  }

    public function order(){
         return $this->belongsTo(Order::class);
      }

user模型（仅供比较）

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

public function addresses(){
       return $this->hasMany(Address::class);
    }

现在我可以获取用户信息，例如

{{$order->user->name}}

但无法获取我的地址信息，例如：

{{$order->address->address}}

我得到的错误：

  

尝试获取非对象的属性

任何想法？

addresses表

Answer 1

address模型中有Order个属性，这就是为什么你总是得到null的原因。这将返回属性而不是相关地址：

$order->address

因此，重命名关系以使其有效：

public function orderAddress()
{
    return $this->belongsTo(Address::class, 'address_id');
}

并使用它：

{{ $order->orderAddress->address }}
