Zend_db只在我的主模块中出错，并且只有当我使用'woningen'作为表名时

Question

This is the code I use to update/insert data in my database.

public function saveItem($post, $table)
    {
        unset($post['submit']);
        $this->_table = new Zend_Db_Table($table); exit;

        if (isset($post['id'])) {
            $where = $this->_table->getAdapter()->quoteInto('id = ?', $post['id']);
            $this->_table->update($post, $where);
            return $post['id'];
        } else {
            return $this->_table->insert($post);
        }
    }

For some reason

$this->_table = new Zend_Db_Table($table);

Gives me a error but only when $table = 'woningen' and only in my main module.

Here is the error:

My first thought, as explained by the error message, is that you have a Zend_Registry key by that name, but not an object of something like a Zend_Db_Adapter_Pdo_Mysql, which is what it's expecting. A random string would not fail for that reason, since it would end up returning false, or null - which simply returns out of the _setupAdapter function without doing anything.
