Question

我正在学习教义2。问题是：我刚刚更新了我的实体类。旧版本的实体由$ id，$ name和$ username字段组成。在下面的更新之后，我运行命令doctrine：generate：entities Acme，doctrine：update：schema等，但结果仍然只有3个字段的旧表。看起来旧的元数据被保存在某个地方。有人可以向我提供我做错的信息吗？为什么我得到旧的数据库表而不是新的？甚至如何解决我的问题？

Answer 1

如果保存旧元数据则必须清除缓存

doctrine:cache:clear-metadata         Clears all metadata cache for an entity manager
  doctrine:cache:clear-query            Clears all query cache for an entity manager
  doctrine:cache:clear-result           Clears result cache for an entity manager

Answer 2

我认为你没有正确执行更新命令。

您需要强制进行更改：

php app/console doctrine:schema:update --force

或转储SQL并手动执行：

php app/console doctrine:schema:update --dump-sql

实体更新后的Doctrine2仍会生成旧的数据库表
