Php Laravel显示多对多关系项

我在Laravel中建立了多对多关系，并用数据填充了数据库表。关系设置如下所示

users.php
---------
   public function houses()
    {
        return $this->belongsToMany('App\House')
        ->withTimestamps();
    }

house.php
---------
public function users()
    {
        return $this->belongsToMany('App\User')
        ->withTimestamps();
    }

$houses = House::with('App\User')->all();

foreach ($houses as $house) {
    echo 'Found House';
}

在my/house/show.blade.php中，我试图显示保存的连接，如下所示

users.php
---------
   public function houses()
    {
        return $this->belongsToMany('App\House')
        ->withTimestamps();
    }

house.php
---------
public function users()
    {
        return $this->belongsToMany('App\User')
        ->withTimestamps();
    }

$houses = House::with('App\User')->all();

foreach ($houses as $house) {
    echo 'Found House';
}

如果说找不到$house，那我就错了。我哪里出错了？

您应该在

中用以下方法指出关系：

$houses = House::with('users')->get();

@foreach ($houses as $house)
    {{ $house->addres }}
@endforeach

$houses = House::whereHas('users', function ($query) {
    $query->where('name', 'some user name'); // to add some conditions on the user :)
})->get(); 

还有一件事，最好在控制器中获取房屋并将其传递给视图：

$houses = House::with('users')->get();
return view('someView')->withHouses($houses);

在视图中，这样做：

$houses = House::with('users')->get();

@foreach ($houses as $house)
    {{ $house->addres }}
@endforeach

$houses = House::whereHas('users', function ($query) {
    $query->where('name', 'some user name'); // to add some conditions on the user :)
})->get(); 


要仅获取房屋，用户可以尝试以下方法：

$houses = House::has('users')->get();

要对用户添加一些条件，您可以这样做：

$houses = House::with('users')->get();

@foreach ($houses as $house)
    {{ $house->addres }}
@endforeach

$houses = House::whereHas('users', function ($query) {
    $query->where('name', 'some user name'); // to add some conditions on the user :)
})->get(); 

你应该试试这个：

$houses = House::with('users')->get();

foreach ($houses as $house) {
    echo 'Found House';
}

或

在控制器中：

use House;

$houses = House::with('users')->get();
return view('someView',compact('houses'));

@foreach ($houses as $house)
    {{ $house->name }}
@endforeach

在刀片文件中：

use House;

$houses = House::with('users')->get();
return view('someView',compact('houses'));

@foreach ($houses as $house)
    {{ $house->name }}
@endforeach

为什么在blade中而不是在controller中？它应该是
House:：with（'users'）
。在controller中而不是在blade中这样做更好吗？我想它应该是->get（）；最后。每当我尝试在控制器中设置它时，我都会得到-调用未定义的方法illumb\Database\Query\Builder:：all（）@fightstarr20立即完成检查我使用的
get
not
all
现在我在模型[App\House]上调用了未定义的关系[App\User]。让我们来看看。
