Question

我使用Admin生成器生成了这个：

abstract class autoNewsActions extends sfActions
{
  public function preExecute()
  {
    $this->configuration = new newsGeneratorConfiguration();

    if (!$this->getUser()->hasCredential($this->configuration->getCredentials($this->getActionName())))
    {
      $this->forward(sfConfig::get('sf_secure_module'), sfConfig::get('sf_secure_action'));
    }

    $this->dispatcher->notify(new sfEvent($this, 'admin.pre_execute', array('configuration' => $this->configuration)));

    $this->helper = new newsGeneratorHelper();

    parent::preExecute();
  }

  public function executeIndex(sfWebRequest $request)
  {
    // sorting
    if ($request->getParameter('sort') && $this->isValidSortColumn($request->getParameter('sort')))
    {
      $this->setSort(array($request->getParameter('sort'), $request->getParameter('sort_type')));
    }

    // pager
    if ($request->getParameter('page'))
    {
      $this->setPage($request->getParameter('page'));
    }

    $this->pager = $this->getPager();
    $this->sort = $this->getSort();
  }

  public function executeFilter(sfWebRequest $request)
  {
    $this->setPage(1);

    if ($request->hasParameter('_reset'))
    {
      $this->setFilters($this->configuration->getFilterDefaults());

      $this->redirect('@news');
    }

    $this->filters = $this->configuration->getFilterForm($this->getFilters());

    $this->filters->bind($request->getParameter($this->filters->getName()));
    if ($this->filters->isValid())
    {
      $this->setFilters($this->filters->getValues());

      $this->redirect('@news');
    }

    $this->pager = $this->getPager();
    $this->sort = $this->getSort();

    $this->setTemplate('index');
  }

  public function executeNew(sfWebRequest $request)
  {
    $this->form = $this->configuration->getForm();

    $this->form = $this->configuration->getForm($this->news);

    $this->processForm($request, $this->form);

    $this->setTemplate('edit');
  }

  public function executeDelete(sfWebRequest $request)
  {
    $request->checkCSRFProtection();

    $this->dispatcher->notify(new sfEvent($this, 'admin.delete_object', array('object' => $this->getRoute()->getObject())));

    if ($this->getRoute()->getObject()->delete())
    {
      $this->getUser()->setFlash('notice', 'The item was deleted successfully.');
    }

    $this->redirect('@news');

如何为此子句添加 WHERE id＆gt; 10 索引中的列表？也许在generator.yml？

Answer 1

使用table_method generator.yml option。

在generator.yml：

config:
  list:
    table_method: buildQueryForAdminIndex

在NewsTable：

public function buildQueryForAdminIndex(Doctrine_Query $q)
{
  $q->addWhere($q->getRootAlias() . '.id > ?', 10);
  return $q;
}

我应该注意，硬编码这个id很糟糕。它应该被抽象，以便清楚为什么值为10。

为管理生成器添加子句WHERE
