こんにちは、リレーションシップ コントローラーの完全に機能する Web ページ (index_admin) がありますが、ページネーションを追加した後、すべてがクラッシュします。

といっしょに：

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Relationship.sender_id' in 'where clause'

顧客と企業は「関係」を築き、当社の Web サイトで請求書を交換できます。DB スキーマは次のとおりです。

ID、sender_id、receiver_id、アクティブ、リクエスト済み、exp​​iry_date

Sender_id と receiver_id はどちらもアカウント テーブルへの外部キーです。つまり、どのアカウントが相互にリンクされているかをデータベースに伝えます。

関係モデル「BELONGSTO」「RECEIVER AND SENDER ACCOUNT MODELS」:

public $belongsTo = array(
        'ReceiverAccount' =>array(
            'className' => 'Account',
            'foreignKey' =>'receiver_id',
            'associationForeignKey'  => 'accounts_id',
            ),
        'SenderAccount' =>array(
            'className' => 'Account',
            'foreignKey' =>'sender_id',
            'associationForeignKey'  => 'accounts_id',)
            );

索引_管理者:

public function index_admin(){
        $this->set('title_for_layout', 'Relationships');
        $this->set('stylesheet_used', 'homestyle');
        $this->set('image_used', 'eBOXLogoHome.png');   
        $this->layout='home_layout';

        //retrieve Account Id of current User       
        $accountid=$this->Auth->user('account_id');

        //Conditions
        $conditions=array(
        "OR"=> array(
            'Relationship.sender_id' => $accountid,
            'Relationship.receiver_id' => $accountid)
        );



        //Find all Invoices where receiver_id = accountid
        $relationships=$this->Relationship->find('all', array(
        'conditions' => $conditions));

        debug($conditions);

        $compName = $this->Account->field('account_name', array('id' => 'Relationship.id'));

        $this->paginate = array(
        'limit' => 10,
        'conditions'=> $conditions
        );

        $this->set('accountid', $accountid); 
        $this->set('relationship', $this->paginate());  

        $this->set('compName', $compName);  
    }

私が言ったように、それはすべて事前に機能していましたが、今はそうではありませんが、その理由はわかりません。

デバッグ モードをオンに設定して、考えられるすべてのエラーを詳細に確認することをお勧めします。意図したテーブルに「sender_id」フィールドがないことが明らかなSQLエラー部分を共有しました。デバッグモードがオンになっていると仮定しています。まず、生成されたクエリを見てください。次に、クエリが掘り下げようとしているテーブルを見つけます。

クエリが正しいテーブルを参照している場合は、これを試すことができます。

public function index_admin(){
        $this->set('title_for_layout', 'Relationships');
        $this->set('stylesheet_used', 'homestyle');
        $this->set('image_used', 'eBOXLogoHome.png');   
        $this->layout='home_layout';

        //retrieve Account Id of current User       
        $accountid=$this->Auth->user('account_id');

        //Conditions
        $conditions=array(
        "OR"=> array(
            'Relationship.sender_id' => $accountid,
            'Relationship.receiver_id' => $accountid)
        );
        App::import('Model', 'Relationship');
        $objRelationship = new Relationship();
        $this->paginate = array( "conditions" => $conditions, 'limit' => 10 );
        $relationships = $this->paginate( $objRelationship );

        $compName = $this->Account->field('account_name', array('id' => 'Relationship.id'));

        $this->set('accountid', $accountid); 
        $this->set('relationship', $this->paginate());  
        $this->set('compName', $compName);
}
