Kohana 中自动建模器更新功能上的关键'PRIMARY'的重复条目'2'

Question

我试图执行更新，似乎没有工作。我想它与我的回调有关，因为当回调被禁用时更新工作得很好。这是我的尝试块。

try{
      $updatestat=NULL;
      $updateresult=NULL;
      $id = Arr::get($_POST, 'id');
      $scode=trim(Arr::get($_POST, 'stationcode'));
      $sname=trim(Arr::get($_POST, 'stationname'));
      $dsupdate = new Model_Dstations($id);
      $dsupdate->scode = $scode;
      $dsupdate->sname = $sname;
      $validation = new Validation($_POST);          
  $validation->rule('scode', array($dsupdate, 'check_updatecheck' ), array( ':validation', ':value',':field',$id ));
      $validation->rule('sname', array($dsupdate, 'check_updatecheck' ), array( ':validation', ':value',':field',$id ));
      $result['sql']=$dsupdate->save($validation);}

Answer 1

你的代码看起来一团糟。试试这个:

  $dsupdate = new Model_Dstations($id);
  $validation = new Validation($_POST);          
  $validation->rule('scode', array($dsupdate, 'check_updatecheck' ), array( ':validation', ':value',':field',$id ));
  $validation->rule('sname', array($dsupdate, 'check_updatecheck' ), array( ':validation', ':value',':field',$id ));
  if ($validation->check()) {
      $dsupdate->scode = $scode;
      $dsupdate->sname = $sname;
      $dsupdate->save();
  }
