Question

我如何纠正这个错误，我有三个表的profils，compes和competences_profil。我想恢复每个profil的能力，我可以通过查询构建器和具有说服力的能力来检索profils。但是当我想要检索每个profil的权限时，我得到以下错误：未定义的属性：$ stdClass ::

controller :
        $competences = \App\Competence::All();

     $profils = \DB::table('profils')
            ->select(['profils.*']);

        if($request->has('varcate')){
                $profils->join('fonctions','profils.fonctions_id','=','fonctions.id');       
                $profils->join('categos','fonctions.categos_id','=','categos.id');
                $profils->where('categos.id','=',$request->input('varcate'));

        }

        if($request->has('varfonction')){
            if(!$request->has('varcate')){   
                $profils->join('fonctions','profils.fonctions_id','=','fonctions.id');       
            }

            $profils->where('fonctions.id','=',$request->input('varfonction'));
        }

        if($request->has('varstate')){
                $profils->join('citys','profils.citys_id','=','citys.id');       
                $profils->join('states','citys.state_id','=','states.id');
                $profils->where('states.id','=',$request->input('varstate'));

        }

     if($request->has('varcity')){
            if(!$request->has('varstate')){

Answer 1

结帐relationship docs。您可以使用->with('competences')描述与模型内部函数的关系，而不是在控制器内部检索它们。然后你在$ profils对象中拥有它们（关系）。

似乎您使用hasManyThrough关系，因此在Profil模型中：

/**
 * Get all of the competences for profile.
 */
public function competences()
{
    return $this->hasManyThrough('App\Competence', 'App\Competences_profil');
}

Answer 2

试试这个

控制器：

    use App/Profils

public function getProfiles(Profils $profils){

    $profils = $profils;

    if($request->has('varcate')){

        $varcate = $request->get('varcate');
        $profils =  $profils->whereHas('fonctions', function ($query) use ($varcate){
                        $query->whereHas('category', function ($subQuery) use ($varcate) {
                                $subQuery->where('category.id',$varcate);
                        });
                    });
    }

    if($request->has('varfonction')){

        $varfonction = $request->get('varfonction');
        $profils =  $profils->whereHas('fonctions', function ($query) use ($varfonction){
                        $query->where('fonctions.id',$varfonction);
                });
    }

    if($request->has('varstate')){

        $varstate = $request->get('varstate');
        $profils =  $profils->whereHas('citys', function ($query) use ($varstate){
                        $query->whereHas('states', function ($subQuery) use ($varstate) {
                                $subQuery->where('states.id',$varstate);
                        });
                    });
    }

    if($request->has('varcity')){

        $varcity = $request->get('varcity');
        $profils =  $profils->whereHas('citys', function ($query) use ($varcity){
                        $query->where('citys.id',$varcity);
        });

    }


    $profils = $profils->paginate(30);

    return view('profiles',compact('profils'))
}

异型材

 public function fonctions(){
    return $this->belongsTo('App\fonctions','fonctions_id');
}

public function citys(){
    return $this->belongsTo('App\citys','citys_id');
}

public function competences()
{
    return $this->belongsToMany('App\Competence');
}

fonction

public function fonction(){
    return $this->belongsTo('App\category','category_id');
}

市内

public function states(){
    return $this->belongsTo('App\states','state_id');
}

观点：

@foreach($profils as $profil) 
        @foreach($profil->competences as $competence) 
          {{$competence->titre}}
        @endforeach
@endforeach
