【英文标题】：Joomla - Error during store data in Joomla component

【问题描述】：

我正在为 Joomla 3 扩展一个 Joomla 组件。我可以检索数据，但在存储数据期间我遇到了这个问题：

 Table budget not supported. File not found. 

我的表名： vaccount_budget 。

我的模型：budget.php

class VaccountModelBudget extends JModelList


    function __construct()
    
        parent::__construct();
        $array = JRequest::getVar('cid',  0, '', 'array');
        $this->setId((int)$array[0]);
    

    function setId($id)
    
        // Set id and wipe data
        $this->_id  = $id;
        $this->_data    = null;
    

    function &getData()
    
        // Load the data
        if (empty( $this->_data )) 
            $query = ' SELECT * FROM #__vaccount_budget '.
                    '  WHERE id = '.$this->_id;
            $this->_db->setQuery( $query );
            $this->_data = $this->_db->loadObject();
        
        if (!$this->_data) 
            $this->_data = new stdClass();
            $this->_data->id = null;
            $this->_data->tranid = null;
            $this->_data->quantity = null;
            $this->_data->amount = null;
            $this->_data->from = null;
            $this->_data->to = null;
            $this->_data->created_by = null;

        
        return $this->_data;
    

    function store()
       
        $row = $this->getTable('budget');
        $data = JRequest::get( 'post' );
        $row->load(JRequest::getInt('id', 0));

        $user = JFactory::getUser();
        $uID = $user->id;
        $data['created_by'] = $uID;
        $data['from'] = "2015-02-18";
        $data['to'] = '2015-02-18';

        if (!$row->bind($data)) 
            $this->setError($row->getError());
            return false;
        
        // Make sure the transaction record is valid
        if (!$row->check()) 
            $this->setError($row->getError());
            return false;
        
        // Store the web link table to the database
        if (!$row->store()) 
            $this->setError( $row->getError() );
            return false;
        
        return true;
    

控制器：budget.php

class VaccountControllerBudget extends JControllerForm

    function __construct()
    
        parent::__construct();
        // Register Extra tasks
        $this->registerTask( 'add'  ,   'edit' );
    

    function edit($key = NULL, $urlVar = NULL)
    
        JRequest::setVar( 'view', 'budget' );
        JRequest::setVar( 'layout', 'edit'  );
        JRequest::setVar('hidemainmenu', 1);

        $model = $this->getModel('budget');

        parent::display();
    

    function save($key = NULL, $urlVar = NULL)
    
        $model = $this->getModel('budget');
        $task = $this->getTask();
        $link = $task=="apply"?'index.php?option=com_vaccount&view=budget&task=budget.edit&cid[]='.JRequest::getInt('id', 0):'index.php?option=com_vaccount&view=budgets';

        if($task=="save") 
            //$model->checkIn();

            if ($model->store($post)) 
                $msg = JText::_( 'TRANSACTION_SAVED' );
                $this->setRedirect($link, $msg);
             else 
                $msg = $model->getError();
                jerror::raiseWarning('', $msg);
                $this->setRedirect($link);
            
        
    

我可以从数据库中获取数据，但在表单发布数据时无法存储数据。我在哪里做错了？

【问题讨论】：

你在admin下的table目录下创建JTable类了吗？

【参考方案1】：

在以下目录下创建budget.php：Joomla Root/administrator/components/com_vaccount/tables

jimport('joomla.filter.input');

    class TableBudget extends JTable
    
        var $id = null;     
        var $created_by = null;
        // Add your field name here

        function TableBudget(& $db) 
            parent::__construct('#__vaccount_budget', 'id', $db);
        

        function bind($array, $ignore = '')
        
            if (key_exists('params', $array) && is_array($array['params']))
            
                $registry = new JRegistry();
                $registry->loadArray($array['params']);
                $array['params'] = $registry->toString();
            
            return parent :: bind($array, $ignore);
        

        function check()
                       

            return parent::check();
        

        function store($updateNulls = false)
        
            $user = JFactory::getUser();

            $this->created_by=$user->id;


            if(!parent::store($updateNulls))    
                return false;
            
            return true;
