您好，我們有三個(gè)實(shí)體，樂(lè)器，作曲家和曲目。樂(lè)器和作曲家與多對(duì)多的關(guān)系有關(guān)。當(dāng)您單擊樂(lè)器（id）時(shí)，我想顯示為該樂(lè)器編寫(xiě)一些“曲目”的作曲家的數(shù)量。我使用這個(gè)代碼，但我認(rèn)為這不是最干凈的原因，而且我沒(méi)有很好地理解Eloquent和他的方法，你能幫助我嗎？p.s它的工作原理，但我沒(méi)有填滿好。我的儀器控制器：public function getInstrument( Instrument $instrument){$id_compositori= ComposerInstrument::where('instrument_id', $instrument->id)->pluck('composer_id')->toArray();$compositori = Composer::whereIn('id',$id_compositori)->get();return  view('instrumentcomposer',compact(['id_compositori','instrument','compositori']));}我的觀點(diǎn)：@foreach($compositori as $composer)<div class="col-lg-3 col-md-4 col-6">  <img class="img-fluid img-thumbnail" src=" https://i.picsum.photos/id/619/200/300.jpg?grayscale" alt=""><h2>Wrote by  {{ $composer->name }} </h2>   </div>@endforeach謝謝編輯軌道模型class Track extends Model{   public function instrument()   {       return $this->belongsTo(Instrument::class,'instrument_id','id');   }   public function composer()   {       return $this->belongsTo(Composer::class,'composer_id','id');   }}儀器型號(hào)class Instrument extends Model{   public function composers1()   {       return $this->belongstoMany(ComposerInstrument::class);   }   public function tracks()   {       return $this->hasMany(Track::class);   }   public function composers()   {       return $this->hasMany(Composer::class);   }作曲家模型class Composer extends Model{   public function instruments()   {       return $this->belongstoMany(ComposerInstrument::class);   }   public function tracks()   {       return $this->hasMany(Track::class);   }   public function instruments2()   {       return $this->hasMany(Instrument::class);   }   }數(shù)據(jù)透視表模型class ComposerInstrument extends Model{   protected $table = 'composer_instrument';   protected $fillable = ['composer_id','instrument_id'];   public function instruments()   {       return $this->hasMany(Instrument::class);   }   public function composers()   {       return $this->hasMany(Composer::class);   }}對(duì)不起，我很新手
