Doctrine 2：错误：Class“.. \ ..”没有名为“...”的字段或关联 [英] Doctrine 2: Error: Class "..\.." has no field or association named "..."

问题描述

搜索时，我想出了许多具有类似问题的人的结果，但是它们总是与关联错误有关。我正在尝试在数据库中的表格中添加一个简单的文本字段，对于我来说，我无法确定这个时间有什么不同 - 当我以前没有遇到任何问题的时候。 p>

我已经将4个不同的实体添加了一个'record_checksum'字段，但是我将只使用一个，这里为了简化这个例子。 （同样的错误发生在所有4）。

这是一个我的Entity\Cloud.php文件的例子，' record_checksum '字段添加在底部：

 使用Doctrine\ORM\Mapping作为ORM; 
 
命名空间实体; 
 
 / ** 
 * Entity \Cloud 
 * 
 * @orm：Table（name =cloud）
 * @orm：Entity 
 * @orm：HasLifecycleCallbacks 
 * / 
 class Cloud 
 {
 / ** 
 * @var整数$ id 
 * 
 * @orm：Column（name =id，type =integer，length =13）
 * @orm：Id 
 * @orm：GeneratedValue（strategy =IDENTITY ）
 * / 
 private $ id; 
 
 / ** 
 * @var float $ position_x 
 * 
 * @orm：列（name =position_x，type =float，length = 9）
 * / 
 private $ position_x; 
 
 / ** 
 * @var float $ position_y 
 * 
 * @orm：列（name =position_y，type =float，length = 9）
 * / 
 private $ position_y; 
 
 / ** 
 * @var string $ commit_group 
 * 
 * @orm：列（name =commit_group，type =string，length = 32，nullable = true）
 * / 
 private $ commit_group; 
 
 / ** 
 * @var string $ commit_key 
 * 
 * @orm：列（name =commit_key，type =string，length = 13，nullable = true）
 * / 
 private $ commit_key; 
 
 / ** 
 * @var string $ record_checksum 
 * 
 * @orm：Column（name =record_checksum，type =string，length = 32，nullable = true）
 * / 
 private $ record_checksum; 
  

该类的其余部分是getter / setter方法，所以我将把它留下。要查看整个实体文件，我把它放在了pastebin上（ http://pastebin.com/9LheZ6A1 ）。几周前我刚刚添加的commit_key，没有任何问题。

现在我更新架构：

  $ doctrine orm：schema -tool：update --dump-sql 
 ALTER TABLE cloud ADD record_checksum VARCHAR（32）DEFAULT NULL; 
 $ doctrine orm：schema-tool：update --force 
更新数据库模式... 
数据库模式已成功更新！ 
  

我已经验证了该字段现在存在于DB表中。

但是，当我运行这样一个简单的DQL查询：

  $ dql =SELECT c.id AS id，c.commit_key AS key，c.record_checksum AS checksum。 
FROM Entity\\Cloud c WHERE c.commit_group =：commit_group; 
  

我收到错误：

  [语义错误]行0，col 42靠近'record_checksum'：错误：Class Entity\Cloud没有名为record_checksum的字段或关联，
  pre> 
 
 
我已经把我的头撞在墙上一段时间了。我确定我忽略了一些非常愚蠢的东西。任何帮助是极大的赞赏！

解决方案
尝试：
 
 
清除可能包含配置或PHP代码的任何缓存。
 
 
重命名一个字段，以防第一个解决方案无效。
 
 
 
When searching I came up with many results of people having similar problems but they were always related to association errors. I'm trying add a simple text field to a table in a database and, for the life of me, I can't figure out what's different about this time - when I've done it with no problems many times before.

I've added a 'record_checksum' field to 4 different entities, but I will use just one, here to simplify the example. (The same error happens for all 4).

Here is an example of my Entity\Cloud.php file, with the 'record_checksum' field added at the bottom:
use Doctrine\ORM\Mapping as ORM;

namespace Entity;

/**
 * Entity\Cloud
 *
 * @orm:Table(name="cloud")
 * @orm:Entity
 * @orm:HasLifecycleCallbacks
 */
class Cloud
{
    /**
     * @var integer $id
     *
     * @orm:Column(name="id", type="integer", length="13")
     * @orm:Id
     * @orm:GeneratedValue(strategy="IDENTITY")
     */
    private $id;

    /**
     * @var float $position_x
     *
     * @orm:Column(name="position_x", type="float", length=9)
     */
    private $position_x;

    /**
     * @var float $position_y
     *
     * @orm:Column(name="position_y", type="float", length=9)
     */
    private $position_y;

    /**
     * @var string $commit_group
     *
     * @orm:Column(name="commit_group", type="string", length=32, nullable=true)
     */
    private $commit_group;

    /**
     * @var string $commit_key
     *
     * @orm:Column(name="commit_key", type="string", length=13, nullable=true)
     */
    private $commit_key;

    /**
     * @var string $record_checksum
     *
     * @orm:Column(name="record_checksum", type="string", length=32, nullable=true)
     */
    private $record_checksum;
The rest of the class is getter/setter methods, so I will leave it out. To see the entire Entity file, I put it up on pastebin ( http://pastebin.com/9LheZ6A1 ). The 'commit_key' I'd just added a few weeks ago, with no problems. 

Now I update the schema:
$ doctrine orm:schema-tool:update --dump-sql
ALTER TABLE cloud ADD record_checksum VARCHAR(32) DEFAULT NULL;
$ doctrine orm:schema-tool:update --force
Updating database schema...
Database schema updated successfully!
I verified this field now exists in the DB table.

However, when I run a simple DQL query like this:
$dql =  "SELECT c.id AS id, c.commit_key AS key, c.record_checksum AS checksum ".
                "FROM Entity\\Cloud c WHERE c.commit_group = :commit_group";
I get the error:
 [Semantical Error] line 0, col 42 near 'record_checksum': Error: Class Entity\Cloud has no field or association named record_checksum, 
I've banged my head on the wall over this for a while now. I'm sure I'm overlooking something really stupid. Any help is greatly appreciated!

解决方案
Try to:

Clear any cache that may contain the config or PHP code.
Rename a field in case the first solution didn't work.
