如何根据Auth :: user-＆gt; id（）过滤表数据;在Laravel

Question

我正在使用此Controller来获得用户对项目的许可

public function show($id)
 {
     if (Permission::where('status', 1)->where('project_id', $id)->exists()) {
    // if((Permission::where('status', '=', '1')->first()) && (Permission::where('project_id','=',$id)->first())){
        $project = Project::find($id);
        $tasks = $this->getTasks($id);
        $files = $this->getFiles($id);
        $comments = $this->getComments($id);
        $collaborators = $this->getCollaborators($id);
        $permissions = $this->getPermissions($id);
returnview('collaborators.show')->withProject($project)->withTasks($tasks)->withFiles($files)->withComments($comments)->withCollaborators($collaborators);
        }
    else if
        //return('hi');
        (Permission::where('status', 2)->where('project_id', $id)->exists()) {
            $project = Project::find($id);
            $tasks = $this->getTasks($id);
            $files = $this->getFiles($id);
            $comments = $this->getComments($id);
            $collaborators = $this->getCollaborators($id);
            $permissions = $this->getPermissions($id);
             return view('collaborators.manager')->withProject($project)->withTasks($tasks)->withFiles($files)->withComments($comments)->withCollaborators($collaborators);
        }

我的权限模型是

<?php

namespace App;
use Auth;
use Illuminate\Database\Eloquent\Model;

class Permission extends Model
{
     protected $table = 'permissions';


    protected $fillable = ['status','project_id','collaborator_id'];

    public function scopeProject($query, $id)
    {
        return $query->where('project_id', $id);
    }

    public function scopeProjectp($query, $cid)
    {
        return $query->where('collaborator_id', $cid);
    }




    public function scopePermissioneditt($query, $id, $projectId)
    {
        return $query->where('collaborator_id',$id)->where('project_id',$projectId);//->exists();

    }


    public function scopeProjectac($query)
{
     return $query->where('collaborator_id', Auth::user()->id);

}




  /*  public static function permission($collaboratorId, $projectId)
{
    return Permission::where('collaborator_id', $collaboratorId)->where('project_id', $projectId);
}*/

     public function user()
    {
        return $this->belongsTo(User::class, 'collaborator_id');
    }

  /*   public function project()
    {
        return $this->belongsToMany('App\Project');
    }*/


      public function project_collaborator()
    {
        return $this->belongsToMany('App\Collaboration','collaborator_id');
    }




    //
}

我需要根据当前用户Auth :: user-＆gt; id检查和访问权限表;给予许可用户。
