Question

我试图在一个视图中显示2个变量

{{$ match-> title}}和{{$ distance-> unit}}

但是当我dd（）时，只有$ match起作用，而$ distance返回null。它。

我已经尝试过这样做，但是$ distances仍然使我为空

 $matches = BikeGame::find($request->id);
 $distances = Distance::find($request->id);

$matches = BikeGame::where('id',$request->id)->first();
$distances = Distance::where('id',$request->id)->first();

$matches = BikeGame::find($request->get('id'));
$distances = Distance::find($request->get('id'));

我的BikeGame模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class BikeGame extends Model
{
   protected $guarded = [];

   public function distances(){
    return $this->hasMany('App\Distance');   
   }

}

我的距离模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Distance extends Model
{
    protected $guarded = [];

    public function bikegames(){
        return $this->belongsTo('App\BikeGame');
    }

}

我的控制器：

public function bikeGamesMatch(Request $request){ 
    $matches = BikeGame::find($request->id);
    $distances = Distance::find($request->id);
    dd($distances);
    return view('bike_games.match', compact("matches","distances"));
}

我希望我的视图显示此内容

<th scope="col" class="text-center"><strong>Game Title:</strong>
    @foreach($matches as $match)
      {{ $match->title }}
    @endforeach
</th>

<th scope="col" class="text-center"><strong>Target: Distance</strong>
    @foreach($distances as $distance) 
       {{ $distance->distance }} {{ $distance->unit }}
    @endforeach
</th>

Answer 1

尝试使用您在模型中定义的关系。

在您的控制器中：

public function bikeGamesMatch(Request $request) 
{ 
    $match = BikeGame::find($request->id); // note is just one object

    return view('bike_games.match', compact("match"));
}

并在刀片中

<th scope="col" class="text-center">
    <strong>Game Title:</strong>
    {{ $match->title }}
</th>

<th scope="col" class="text-center">
    <strong>Target: Distance</strong>
    @foreach($match->distances as $distance) 
       {{ $distance->distance }} {{ $distance->unit }}
    @endforeach
</th>

BikeGame模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class BikeGame extends Model
{
   protected $guarded = [];

   public function distance(){
    return $this->belongsTo('App\Distance', 'distance_id');   
   }

}

距离模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Distance extends Model
{
    protected $guarded = [];

    public function bikegames(){
        return $this->hasMany('App\BikeGame'); // this could be hasOne, depending on if you are going to use the same distance for other games or not
    }

}

控制器：

public function bikeGamesMatch(Request $request){ 
    $match = BikeGame::find($request->id);

    return view('bike_games.match', compact("match"));
}

查看 bike_games/match.blade.php

<th scope="col" class="text-center"><strong>Game Title:</strong>
    {{ $match->title }}
</th>

<th scope="col" class="text-center"><strong>Target: Distance</strong>
    @isset($match->distance)
    {{ $match->distance->distance }} {{ $match->distance->unit }}
    @endisset
</th>
