Some notes for symfony

View Template Shortcuts

• $sf_context: The whole context object (instance of sfContext)
• $sf_request: The request object (instance of sfRequest) 
• $sf_params: Parameters of the request 
• $sf_user: The current user session object (instance of sfUser)

Get XML information in symfony 1.4

When parse a remote xml file, I use sfWebBrowserPlugin and get the right result, like this way:

in actions code

$tar = new sfWebBrowser();
$tar->post(url_for('MsgTransfer/Recommender', true), http_build_query($this->form->getValues()));
$this->xml = $tar->getResponseXML(); 

in template code

php echo $xml->string;

then i get the error message:

Fatal error: Call to undefined method SimpleXMLElement::__toString() in /usr/share/php/symfony/escaper/sfOutputEscaperObjectDecorator.class.php on line 98

The solution to solve is use:

php echo $sf_data->getRaw('xml')->string;

sfGuardPlugin Data-Dump & Data-Load UserPassword error solution

Please rewrite signin function from sfGuardPlugin/lib/model/plugin/PluginsfGuardUser.php as following:

(For Propel)

public function setPassword($password)
  {
    if (!$password && 0 == strlen($password))
    {
      return;
    }
/*
 * iba: if salt is set then probly the passwort is already encrpted
 * thus call setPassword without user_funx algorythm
 */
    /*--- Add Here ---*/
    $fromdump = false;
    if($this->isNew() && $this->getSalt()){
      $fromdump=true;
    }
    /*----------------*/

    if (!$salt = $this->getSalt())
    {
      $salt = md5(rand(100000, 999999).$this->getUsername());
      $this->setSalt($salt);
    }
    $algorithm = sfConfig::get('app_sf_guard_plugin_algorithm_callable', 'sha1');
    $algorithmAsStr = is_array($algorithm) ? $algorithm[0].'::'.$algorithm[1] : $algorithm;
    if (!is_callable($algorithm))
    {
      throw new sfException(sprintf('The algorithm callable "%s" is not callable.', $algorithmAsStr));
    }
    $this->setAlgorithm($algorithmAsStr);

/*
 * iba: if passwort is already encrypted dont encrypt it again.
 */
    /*--- Add Here ---*/
    if($fromdump){
      parent::setPassword($password);
    }
    /*----------------*/

    else{
      parent::setPassword(call_user_func_array($algorithm, array($salt.$password)));
    }   
    
  }

New way to loadHelper for symfony 1.2

In Action class file:

Before -

sfLoader::loadHelper("helper");

New way -

sfContext::getInstance()->getConfiguration()
->loadHelpers("helper");

symfony "schema.yml" file

`schema.yml` 文件包含了所有的資料庫表格的規劃描述。每個都通過如下訊息描述：

 * `type`: 資料類型 (`boolean`, `tinyint`, `smallint`, `integer`, `bigint`, `double`,
                                   `float`, `real`, `decimal`, `char`, `varchar(size)`, `longvarchar`,
                                   `date`, `time`, `timestamp`, `blob`,  `clob`)

 * `required`: 設為 `true` 用來表示此欄位內容不得為空白

 * `index`: 設為 `true` 為該表格創建索引鍵，或者設置 `unique` 在該表格上創建唯一索引鍵。

對於設置資料內容為 `~` (`id`, `created_at`, 和 `updated_at`) 的資料，symfony 會探測最合適的
配置方式（`id`是作為主鍵，`created_at` 和 `updated_at`是時間戳記）

**NOTE**
`onDelete`: 屬性定義了外鍵的`ON DELETE`行為。Propel 只是 `CASCADE`, `SETNULL`,
                   `RESTRICT` 等幾種。
例如，删除一條 `job` 紀錄後，`jobeet_job_affiliate` 中所有相關
紀錄也會自動通過數據庫删除。如果底層的數據庫引擎不支持該功能，Propel可以做到。

Backend Admin FileUpload for symfony 1.2

This approach is to provide a path option to sfValidatorFile...
--------------------------------------------------------------

// lib/form/StudentForm.class.php
class StudentForm extends BaseStudentForm
{
    public function configure()
    {
        $this->widgetSchema['photo'] = new sfWidgetFormInputFile();
        $this->validatorSchema['photo'] = new sfValidatorFile(array(
        'path' => sfConfig::get('sf_web_dir').'/uploads/students',
        ));
    }
}

--------------------------------------------------------------
And write a generatePhotoFilename() method on Student (assuming "Photo" is the phpName for the field name "photo")
--------------------------------------------------------------

// lib/model/Student.php
class Student extends BaseStudent
{
    public function generatePhotoFilename(sfValidatedFile $file)
    {
        return $file->getOriginalName();
    }
}

--------------------------------------------------------------

This way is probably the preferred approach as it makes for a thinner controller.
