調用成員函數getAllHash

Question

我試圖運行atk4網站上提供的示例代碼。下載了代碼，創建了模型和生成頁面。然而，當我試圖使用生成的http://localhost/demo/atk4-example/?page=generate SQL，我在Apache的錯誤日誌中有以下錯誤：

[Mon Sep 19 21:35:31 2011] [error] [client 127.0.0.1] PHP Fatal error: Call to a member function getAllHash() on a non-object in /var/www/html/demo/atk4-example/atk4-addons/mvc/Page/SchemaGenerator.php on line 69, referer: http://localhost/demo/atk4-example/?page=generate 

這裏是型號：

Category.php：

class Model_Category extends Model_Table { 
    public $entity_code = 'category_table'; 
    public $table_alias = 'ct'; 
    function init(){ 
     parent::init(); 

     $this->addField('name'); 
    } 
} 

工作.php：

class Model_Job extends Model_Table { 
    public $entity_code = 'job_table'; 
    public $table_alias = 'jt'; 
    function init(){ 
     parent::init(); 
     $this->addField('category_id')->refModel('Model_Category'); 
     $this->addField('type'); 
     $this->addField('company'); 
     $this->addField('logo'); 
     $this->addField('url'); 
     $this->addField('position'); 
     $this->addField('location'); 
     $this->addField('description')->type('text'); 
     $this->addField('how_to_apply')->type('text'); 
     $this->addField('is_public')->type('boolean'); 
     $this->addField('is_activated')->type('boolean'); 
     $this->addField('email'); 
     $this->addField('token'); 
     $this->addField('created_dts')->type('timestamp')->system(true); 
     $this->addField('updated_dts')->type('timestamp')->system(true); 
     $this->addField('expires_at')->type('date')->system(true); 
    } 
} 

page/generate.php：

class page_generate extends Page_SchemaGenerator {} 

我是否缺少一些路徑設置？

Answer 1

Call to a member function getAllHash() on a non-object in 
/var/www/html/demo/atk4-example/atk4-addons/mvc/Page/SchemaGenerator.php 
on line 69 

和這條線是

$res = $this->api->db->getAllHash("desc $table"); 

意味着$this->api->db不是一個對象。
看看atk4-example/page/dbtest.php。它調用$this->api->dbConnect();，它可能會設置api-> db屬性。
