当我尝试运行查询时出现此错误。

BadMethodCallException 调用未定义的方法Illuminate \ Database \ Query \ Builder :: with（）

我的搜索控制器在数据库中查找基于URI http://localhost:8000/search/projects/email_category/foo@foo.com_spel+kod-game+code的特定项目

class SearchController extends BaseController {
  //foo.com/search/project/email_category/foo@foo.com-admin@foo.com_spel+kod-game+code
  public function index($option, $key, $val){
    $keys = explode('_', $key);
    $vals = explode('_', $val);
    $data = [];

    for($i = 0; $i < sizeof($keys); $i++){
      $data[$keys[$i]] = explode('-', $vals[$i]);
    }
    $json = json_encode($data);
    echo "<pre>" . $option . ": " . $json . "</pre>";

    // Get all rows in option table, but we are going to sort things out before calling it with ->get();
    $table = DB::table($option);
    foreach($data as $key => $value){
      foreach($value as $string){
        $split = explode('+', $string);
        foreach ($split as $explode){
          if(end($split) !== $explode){
            switch($key){
              case 'email':
                $table->with(array('User' => function($query) use ($key, $explode){
                  $query->where('email',"=",$explode);
                }));
                    break;
              case 'categories':
                $table->Category->where('typ',"=",$explode);
                break;
              default:
                $table->where($key,"=",$explode);
                    break;
            }
          }
        }
        switch($key){
          case 'email':
            $table->with(array('User' => function($query) use ($explode){
              $query->orWhere('email',"=",$explode);
            }));
            break;
          case 'categories':
            $table->Category->orWhere('typ',"=",$explode);
            break;
          default:
            $table->orWhere($key,"=",$explode);
            break;
        }
      }
    }
    $table->get(); // Runs the query we have build up.

  }
}

用户模型

<?php

use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface {

    use UserTrait, RemindableTrait;

    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = array('password', 'remember_token');

    public function project() 
    {
        return $this->hasMany('Project');
    }

    public function experience()
    {
        return $this->hasMany('Experience');
    }

    public function reference()
    {
        return $this->hasMany('Reference');
    }

    public function stat()
    {
        return $this->hasMany('Stat');
    }

}

项目模型

<?php

class Project extends Eloquent 
{

protected $table = 'projects';

    public function user()
    {
        return $this->belongsToMany('User');
    }

    public function category()
    {
        return $this->hasMany('Category');
    }

    public function stat()
    {
        return $this->hasMany('Stat');
    }
}

我试图关注Laravels网页上的一些例子。我做了一个测试字符串查询，显示正确的字符串，但现在我需要它在ORM中。我已经尝试过我自己解决这个问题已经有好几天了，之前我从来没有在Stackoverflow中发布任何内容，如果你发现一些不清楚的评论，我会添加它。

我不知道这是否能解决所有事情，但是对于初学者而言，使用的是模型而不是DB::table()：

// ...

$model = studly_case($option);
$table = new $model;

// ...
