Question

我需要在mongoid.yml中设置选项。它在开发中工作，但heroku中的生产给出了忽略警告消息。有人经历过以及如何解决这个问题吗？

header('Content-type: text/xml');

// INITIALIZE DOM OBJECT
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->formatOutput = true;            
$dom->preserveWhiteSpace = false;

// CREATE ROOT AND APPEND TO DOCUMENT
$xmlRoot = $dom->createElement("persons");
$xmlRoot = $dom->appendChild($xmlRoot);

// QUERY DATABASE
$db = new PDO('mysql:host=localhost;dbname=xxx','root','');
$stmt = $db->prepare("select * from users");
$stmt->execute();

// FETCH ROWS ITERATIVELY
while($row = $stmt->fetch()){
     // APPEND PERSON AS CHILD OF ROOT
     $personNode = $xmlRoot->appendChild($dom->createElement('person'));
     // APPEND CHILDREN TO PERSON         
     $personNode->appendChild($dom->createElement('id', $row['id']));
     $personNode->appendChild($dom->createElement('username', $row['username']));
     $personNode->appendChild($dom->createElement('password', $row['password']));
     $personNode->appendChild($dom->createElement('realname', $row['realname']));
     $personNode->appendChild($dom->createElement('surname', $row['surname']));
     $personNode->appendChild($dom->createElement('email', $row['email']));
     $personNode->appendChild($dom->createElement('created', $row['created']));
     $personNode->appendChild($dom->createElement('admin', $row['admin']));
}
$stmt = null; 
$db = null;

// OUTPUT TO SCREEN
echo $dom->saveXML();

在mongoid.yml

这是Mongo db在尝试查找任何记录时给出的错误，它在数据库中不匹配。为了解决这个问题

在生产配置中添加此行
raise_not_found_error：false

mongoid.yml
production:
  clients:
    default:
      database: database_name
      hosts:
        - localhost:27017
      options:
        read:
          mode: :primary
        max_pool_size: 1
        raise_not_found_error: false

警告 - ：MONGODB |不支持的客户端选项'raise_not_found_error'。它会被忽略
