CakePHP2でToo few arguments to function FollowsController::follow(), 0 passed and exactly 1 expected

Question

CakePHP２でTwitterのクローンサイトを作成しています。その中で「Too few arguments to function FollowsController::follow(), 0 passed and exactly 1 expected」というエラーを解決したいです。follow　メソッドの引数が足らないという事だと思うのですが、どのように確認して行けばいいかが分かりません。
色々触ったので醜いコードになってるかも知れませんが、ご教授頂けると幸いです。

<?php
class FollowsController extends AppController
{   
    //    public function get_user_Info($id)
	//    {
	// 		$profileImage = $this->User->findById($id);
	// 		$this->set('image',$profileImage['User']['profile_Image']); 
	//    }
	
	public function userAction($user)
	{
		$user = $this->User->get('User')->getUserRecord($user['username']);
	    
		if(!$user) {$this->httpNotFound();}
	
		$statuses = $this->Status->get('Status')->getPostMessage($user['id']);
	
		$state = null;
		if ($this->_session->isAuthenticated()) {
			$loginUser = $this->_session->get('user');
			if($loginUser['id']!==$user['id']) {
				$state = $this->State->get('Following')
				->isFollowedUser($loginUser['id'],$user['id']);
			}
	 	}
    }
	
	public function follow($following_id) 
    {
		$id = $this->Auth->user('id');
		$uid = $this->Auth->User('user_id');
    	$this->Follow->create(array('user_id'=> $id,'following_id'=>$following_id));
		if ($this->Follow->save()) {
			$this->redirect('/users/find');
        	$this->set('follow',$following_id);
		}else{
		    $this->Session->setFlash('Not found');
		}	
	}
}

                   FROM follows
                   WHERE user_id = :user_id
                   AND following_id = :following_id
                   ";
            
            $data= $this->getRecord($sql,array(':user_id'=> $user_id,
                                               ':following_id'=>$following_id));
            
            
            if($data['count']!=='0')
            {
                return true;
            }
                return false;     
        }
