Hallo Leute, wir haben eine perfekt funktionierende Webseite (index_admin) des Relationships Controllers, aber nach dem Hinzufügen von Paginierung stürzt alles ab.

Einfallen mit:

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

Kunden und Unternehmen bauen 'Beziehungen' auf, damit sie Rechnungen über unsere Website austauschen können. Hier ist das DB-Schema:

ID, Sender_ID, Empfänger_ID, Aktiv, Angefordert, Ablaufdatum

Sender_id und Receiver_id sind beide Fremdschlüssel für die Kontentabelle. Mit anderen Worten, sagt der Datenbank, welche Konten miteinander verbunden sind.

Beziehungsmodell 'BELONGSTO' 'EMPFÄNGER- UND SENDER-KONTO-MODELLE':

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

Index_admin:

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);  
    }

Index_admin-Ansicht (teilweise):

Wie ich schon sagte, es hat alles vor der Hand geklappt, jetzt ist es nicht mehr so, aber ich kann nicht verstehen, warum.
