Laravel雄辩的财产不'；此集合中不存在

我有业务和地址表以及数据透视表

当用户点击他们想要查看的业务时，会搜索业务id，并使用我想要的id获取其所属地址的详细信息。所以我有这样的想法：

public function displayBusiness($id) {
    /*
    $business = Business::with('addresses')->find($id);
    $session = session()->put('key', $id);
    $gallery = Gallery::where('business_id', $id)->get();
    $location = Location::where('business_id', $id)->get();
    $review = Review::where('business_id', $id)->get();
        return view('displayBusiness', compact('business', 'address', 'gallery', 'location', 'review', 'items'));

}

我的商业模式：

public function addresses()
{
    return $this->belongsToMany('App\Address', 'business_address', 'business_id', 'address_id');
}

public function businesses()
{
    return $this->belongsToMany('App\Business', 'business_address', 'business_id', 'address_id');
}

地址模型：

public function addresses()
{
    return $this->belongsToMany('App\Address', 'business_address', 'business_id', 'address_id');
}

public function businesses()
{
    return $this->belongsToMany('App\Business', 'business_address', 'business_id', 'address_id');
}

在我看来：

<div class="container container2">
        <div id="left" class="logo2">
        <img class="images" id="image" src="{{ asset($business->image) }}" />
            <form class="upload_form" action="{{ action('ImageController@image') }}" enctype="multipart/form-data" role="form" method="POST">
            <input type="hidden" name="_token" value="{{ csrf_token() }}">
            <input style="width: 100%;height: 100%; opacity: 0;" name="img" id="img" class="img" data-input="false" type="file" data-buttonText="Upload Logo" data-size="sm" data-badge="false" onchange="submitImage();" />
                </form>
        </div>
<!-- Business Information -->
        <div class="info sortable">
        <input type="hidden" name="id" value="{{$business->id}}"/>

            <p>{{$business->name}}</p>
            <p>{{$business->email}}</p>
            <p>{{$business->addresses->firstline_address}}</p>
            <p>{{$business->addresses->secondline_address}}</p>
            <p>{{$business->addresses->town}}</p>
            <p>{{$business->addresses->city}}</p>
            <p>{{$business->addresses->postcode}}</p>
            <p>{{$business->addresses->telephone}}</p>
        </div>

{{$business->name}

{{$business->email}

{{$business->address->firstline_address}

{{$business->address->secondline_address}

{{$business->address->town}

{{$business->address->city}

{{$business->address->postcode}

{{$business->地址->电话}

但是，我得到一个错误：

此集合实例上不存在属性[firstline_address]

如何解决这个问题？

像这样试试

$business->addresses()->value('firstline_address');

像这样试试

$business->addresses()->value('firstline_address');

---

给定地址-业务是多个关系，地址是一个集合，因此请尝试这样做

@foreach( $business->addresses as $address )
   <p>{{$address->firstline_address}}</p>
   .....
@endforeach

@foreach（$business->地址为$address）
{{$address->firstline_address}

.....
@endforeach

@foreach（$business->地址为$address）
{{$address->firstline_address}

.....
@endforeach

您不能执行

$business->address->firstline\u address

，因为

$business->address

是地址的集合，而不是单个对象

您有两种选择：

选项1：foreach循环：

@forelse({{$business->addresses as $adresse)
    <p>{{$adresse->firstline_address}}</p>
        <p>{{$adresse->secondline_address}}</p>
        <p>{{$adresse->town}}</p>
        <p>{{$adresse->city}}</p>
        <p>{{$adresse->postcode}}</p>
        <p>{{$$adresse->telephone}}</p>
@empty
    <p> No Adresses </p>
@endforelse

@forelse（{{{$business->地址为$address）
{{$ADRESE->第一行地址}

{{$adresse->第二行地址}

{{$ADRESE->town}

{{$ADRESE->city}

{{$ADRESE->邮政编码}

{{$$ADRESE->电话}

@空的
没有地址

@endforelse

选项2：您只需要第一个地址

        <p>{{$business->name}}</p>
        <p>{{$business->email}}</p>
        <p>{{$business->addresses->first()->firstline_address}}</p>
        <p>{{$business->addresses->first()->secondline_address}}</p>
        <p>{{$business->addresses->first()->town}}</p>
        <p>{{$business->addresses->first()->city}}</p>
        <p>{{$business->addresses->first()->postcode}}</p>
        <p>{{$business->addresses->first()->telephone}}</p>

{{$business->name}

{{$business->email}

{{$business->address->first（）->firstline_address}

{{$business->address->first（）->secondline_address}

{{$business->addresses->first（）->town}

{{$business->address->first（）->city}

{{$business->address->first（）->postcode}

{{$business->address->first（）->telephone}

这很好用。你能解释一下你的代码和我的代码有什么不同吗？还有我怎么说->地址是否为空？例如，显示未知？如果你使用

dd（）

对于检索到的数据，您可以看到数据的结构。实际上我在这里所做的是调用您创建的模型并访问值。它是用于

（）

必须存在并且

value

用于获取特定列的值。可能有不同的方式我可能不知道…对于验证，您可以使用PHPso中的

isset

或

empty

方法，类似于if（！empty（$business->addresses（））然后做点什么？这很好。你能解释一下你的代码和我的代码之间的区别吗？还有我怎么说->地址是否为空？例如显示未知？如果你使用
