php - Symfony，在路由方法中获取GET参数

Question

有问题。

有我的路由方法:

book_list:
  url:      /api/books.:sf_format
  class:    sfDoctrineRoute
  options:  { model: Book, type: list, method: getActiveWithAuthor }
  param:    { module: book, action: list, sf_format: json }
  requirements:
    sf_format: (?:json|html)

实际代码很简单:

public function executeList(sfWebRequest $request) {
    $this->books = $this->getRoute()->getObjects();
}

和获取书籍的自定义方法

public function getActiveWithAuthor(array $parameters) {
    // crit is easy to find in logs.
    sfContext::getInstance()->getLogger()->crit(var_export($parameters, true));
    return BookQuery::create()
    ->addSelf()
    ->addAuthor()
    ->execute();
}

问题是，我想通过可选参数“date_from”来过滤书籍，该参数可以在 url 中，例如/api/books?date_from=2011-02-18

但在日志中我只能看到“sf_format => html”(或 json)我应该使用什么来获取可选参数“date_from”？

Answer 1

public function executeList(sfWebRequest $request) 
{
  $this->books = Doctrine::getTable('Book')-> getActiveWithAuthor($request->getParameter('date'));
}

//BookTable.class.php
public function getActiveWithAuthor($date) 
{
  $q = $this->createQuery('b')
    ->leftJoin('b.Author')
    ->where('b.date > ?', $date);

  return $q->execute();  
}
