Symfony 使用 Doctrine 和 MySQL

Question

为了使用 schema.yml 来处理关系，你必须使用 InnoDB 吗？这是我的架构：

BuybackStatus:
  connection: doctrine
  tableName: buyback_statuses

但数据库是 MyISAM。所以当我运行时：php symfony doctrine:build --model 我得到了一堆这些：

Notice: Undefined index:  class in /home/kacie/cellphone/lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/vendor/doctrine/Doctrine/Import/Builder.php on line 672

我是 Symfony 的新手，所以我可能搞砸了架构，请检查。

这是它实际加载的内容：

但是在此之前有一堆未定义的索引通知，我不想再进一步了，我现在已经废弃了几次应用程序并尝试了很多东西，但我认为这个架构可以工作。控制这里的数据库创建的人一心想着 MyISAM，所以如果我能做些什么来解决它，我不想让他改变它。可悲的是，我有创建数据库的脚本，但是当我从已有的结构中生成模式时，它会忽略关系，而且由于我是 symfony 的新手，所以我希望一切都尽可能自动化。

Answer 1

我认为问题在于您两次使用相同的关系名称。 我发现至少三个：“UserState”、“BuyBackModel”、“BuyBackQuality”，它们在您的 schema.yml 中使用了两次

尝试确保所有关系都是唯一的，然后再次尝试生成模型。

编辑

您应该尝试的另一件事是将类名添加到您的关系中。

<...>
Relations:
   class: foo
<...>

Answer 2

我遇到了这个问题。这些想法都没有奏效，因为我认为这是另一个问题。

./symfony 学说：构建模式

不断将不再存在的旧关系放入我的架构中。因此，要么 Symfony 有一些模糊的地方缓存了旧的关系，要么 MySQL 报告了不再存在的关系。

我认为 Symfony 正在从其他来源（如表单或过滤器）中提取关系。我将尝试清除表单和过滤器的基本目录。

嗯。找到了。在 MySQL、我的 GUI 和 WorkBench 中，外键没有被删除。您也必须删除索引。

最佳解决方案。备份您的数据库结构和内容。如果 MySQL 的 GUI 工具出现问题，请重新创建数据库。
