Question

我有三种型号：

意甲（$ id）

public function saisons() 
{
    return $this->hasMany(Season::class);
}

public function episodes() 
{
    return $this->hasManyThrough(Episode::class, Season::class);
}

季节（$ serie_id）

public function serie()
{
    return $this->belongsTo(Serie::class);
}

public function episodes() 
{
    return $this->hasMany(Episode::class);
}

集锦（$ season_id）

public function season()
{
    return $this->belongsTo(Season::class);
}

public function serie()
{
    return $this->BelongsToThrough(Serie::class, Season::class);
}

我想在意甲中展示一个特定的赛季，并将其与相关的事件相关联

我的观点

<h1 class="title">{{$serie->seasons->number}}</h1>


@foreach ($serie->seasons->episodes as $episode)

        <div class="row">
            <div class="columns">
                <div class="col">
       {{$episode->number}}
       <a href="{{route('episodes.show', $episode->id)}}">{{$episode->name}}</a>



        @if(isset($episode->programmation->date))

            {{$episode->programmation->date}}

        @endif
       @if (($episode->season_finale) == '0')
            Non
            @elseif (($episode->season_finale) == '1')
            Oui
            @endif

        @foreach ($episode->chaines as $chaine)
                   {{$chaine->name}}

            @endforeach
        </div>
        </div>
    </div>
    @endforeach

路线

Route::get('/serie/{serie}/saison/{season}', 'Front\SaisonController@show')->name('saison.show');

对于我的网址，我选择显示病房号而不是ID，我认为这就是问题所在。

我该如何以正确的方式做到这一点？

Answer 1

我认为这种方法可以为您提供帮助。

$serie = Serie::where('id',$id)->with('seasons'=>function($query) use ($season_id) {
            $query->where('season_id',$season_id)->with('episodes')->get();
    })->get();

Answer 2

好吧，有人帮助我找到正确的答案：

SELECT t1.day, t1.speed, t1.nor
  FROM (SELECT id, day, ABS(report.speed) AS speed, nor
          FROM report 
         WHERE report.name = 'SYN' 
           AND report.day > '2016-01-01 00:00:00' 
           AND report.speed BETWEEN -40 AND -0.0001) AS t1,
       (SELECT AVG(ABS(speed)) + 3 * STD(ABS(speed)) AS value
          FROM report 
         WHERE report.name = 'SYN' 
           AND report.day > '2016-01-01 00:00:00' 
           AND report.speed BETWEEN -40 AND -0.0001) AS t2
 WHERE t1.speed < t2.value
   AND t1.nor < t2.value;
