我在cakephp中有一些代码会产生错误.
这是PHP控制器:
$this->loadModel( 'Vote' ); //Newly added by amit start
$vote=$this->Vote->getVote($id,$uid);
$this->set('vote',$vote);
$voteCount = count($vote);
$this->set('voteCount',$voteCount);
$voteShow = $this->Vote->find('all', array(
'fields' => array('SUM(Vote.score) AS score','count(id) as countId'),
'conditions'=>array('Vote.type_id'=>$id),
));
$this->set('voteShow',$voteShow);

模型:
public function getVote($id,$uid) {
if (empty($conditions))
$conditions = array('Vote.type' => 'blog',
'Vote.type_id' => $id,
'Vote.user_id' => $uid);
$users = $this->find('all', array('conditions' => $conditions,
'order' => 'Vote.id desc'
));
return $users;
}

这个错误是什么意思?
我想出了一个问题.
这是我的方法如下:
public void someMethod()
{
StringBuilder newFile = new StringBuilder();
String edited = "My String Line";
newFile.append(edited);
newFile.append("\n");
FileWriter fstreamWrite = new FileWriter("transaction.txt");
BufferedWriter out = new BufferedWriter(fstreamWrite);
out.write(newFile.toString());
out.close();
}

当我在我的主类中多次调用此方法时,这段代码创建了一个带有"My String Line"行的transaction.txt.但是当我多次调用这个方法来编写"我的字符串行"时,它只是覆盖了行而没有给我输出像.

当我打电话给方法3次.
有没有想过如何通过多次调用相同的方法多次写同一行?
