Question

我在使用CaseCollectionsCaseMap创建SingleCase时遇到问题。

这是我的数据库结构：

$singleCase = new SingleCase();
$singleCase->setCaActive($singleCaseDTO->getStatus());
$singleCase->setCaUrlcode($singleCaseDTO->getUrl());
$singleCase->setCaAuthorId($user->getUsrId());
$singleCase->setCaAuthorName($user->getUsrName());
$singleCase->setCaCreated();
$singleCase->setCaModified();
$this->singleCaseRepository->create($singleCase);

这是我的Doctrine ORM文件：

SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column "ca_id" violates not-null constraint
DETAIL: Failing row contains (null, null, /new-question, null, 0, 1, XX, 2017-12-03 13:22:18, 2017-12-03 13:22:18).

在我的CommandHandler中，我向CaseCollectionsCase repo注入了SingleCase repo。

当我只创建SingleCase时：

$defaultCollection = new CaseCollectionsCaseMap();
$defaultCollection->setCollection($cc);
$defaultCollection->setCccaPriority(0);

$singleCase->setDefaultCollection($defaultCollection);
$this->singleCaseRepository->create($singleCase);

Doctrine抛出错误：

A new entity was found through the relationship 'PPK\Domain\Entity\SingleCase\SingleCase#defaultCollection' that was not configured to cascade persist operations for entity

添加CaseCollectionsCaseMap仍然没有帮助：

An exception occurred while executing 'INSERT INTO cases (ca_id, ca_urlcode, ca_active, ca_author_id, ca_author_name, ca_modified, ca_created, ca_parent_id, ca_defaultcollection_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)' with params [null, "\/new-question", 0, 1, "XX", "2017-12-03 13:26:26", "2017-12-03 13:26:26", null, null]

学说抛出：

using Word = Microsoft.Office.Interop.Word;

public class Agenda {
  public static void Create() {
    Word.Application wordApplication = null;
    Word.Document wdDocument = null;
    Word.Template wdTemplate = null;
    Word.BuildingBlock wdBuildingBlock = null;

    object paramBBCategory = "Agenda";
    object paramBBName = "Header";

    try {
      wordApplication = new Word.Application();
      wdDocument = wordApplication.Documents.Add(Properties.Settings.Default.Template);
      wdTemplate = (Word.Template)wdDocument.get_AttachedTemplate();

      wdBuildingBlock = wdTemplate
        .BuildingBlockTypes.Item(Word.WdBuildingBlockTypes.wdTypeQuickParts)
        .Categories.Item(ref paramBBCategory)
        .BuildingBlocks.Item(ref paramBBName);
      wordBuildingBlock.Insert(wdDocument.Paragraphs.Last.Range);
    } catch { }
  }
}

当我添加级联：[＆＃34; persist＆＃34;，＆＃34; merge＆＃34;]到defaultCollection doctrine throws：

{{1}}

调用persist会生成$ caId，但刷新会使其为空。

非常感谢任何帮助。

你使用什么数据库？如果它不是MySQL，我建议您使用"AUTO"生成策略作为您的ID。要查看哪些dbs不支持"AUTO"策略，请参阅http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/basic-mapping.html#identifier-generation-strategies

更新：抱歉犯了错误。如果您指定SEQUENCE，即使它说postgres不支持AUTO，显然仍然会使用SEQUENCE策略。我能够从这个问题https://github.com/doctrine/doctrine2/issues/6429中找到答案。从此判断，您应该明确将ID策略设置为IDENTITY。很抱歉早些时候误导了你。
