Symfony2: Database schema and entities not updating with changed metadata
提问by Apothan
I am having trouble updating the schema in Symfony2.
我在 Symfony2 中更新架构时遇到问题。
I have imported a database into Symfony2 using doctrine and that created all the ORM files in YML.
我已经使用学说将一个数据库导入到 Symfony2 中，并在 YML 中创建了所有 ORM 文件。
I have created all the entities from this metadata and it worked great, but if I want to change the database schema using the orm.yml files, It does not update my database or even update the entities when I regenerate them.
我已经从这个元数据中创建了所有的实体并且它工作得很好，但是如果我想使用 orm.yml 文件更改数据库架构，它不会更新我的数据库，甚至不会在我重新生成实体时更新它们。
The import created the orm.yml files in /src/{name}/{my}bundle/Resources/config/doctrine/metadata/orm/{table}.orm.yml
导入在 /src/{name}/{my}bundle/Resources/config/doctrine/metadata/orm/{table}.orm.yml 中创建了 orm.yml 文件
It was created with no errors.
它的创建没有错误。
When I do:
当我做：
php app/console doctrine:schema:update --dump-sql
it displays:
它显示：
ALTER TABLE accounttypes CHANGE description description VARCHAR(45) NOT NULL
So I:
所以我：
php app/console doctrine:schema:update --force
And:
和：
Updating database schema...
Database schema updated successfully! "1" queries were executed
I can do this over and over again and the same query appears and I execute it and it tells me it is done, but again it shows that it needs to be done again.
我可以一遍又一遍地执行此操作，然后出现相同的查询并执行它，它告诉我它已完成，但它再次表明它需要再次完成。
I then have gone to the orm.yml files and changed them drastically, but nothing no new queries appear other than the one that is always there when I do this.
然后我去了 orm.yml 文件并彻底更改了它们，但是除了我这样做时总是存在的查询之外，没有任何新查询出现。
The file AccountTypes.orm.yml
文件 AccountTypes.orm.yml
Accounttypes:
type: entity
table: accounttypes
fields:
description:
id: true
type: string
length: 45
fixed: false
nullable: false
generator:
strategy: IDENTITY
lifecycleCallbacks: { }
Change to this:
改成这样：
Accounttypes:
type: entity
table: accounttypes
id:
id:
type: integer
generator: { strategy: AUTO }
fields:
description:
id: true
type: string
length: 50
lifecycleCallbacks: { }
And it still tells me I need to:
它仍然告诉我我需要：
ALTER TABLE accounttypes CHANGE description description VARCHAR(45) NOT NULL
I have also tried using DoctrineMigrationsBundle and the same query shows up needing done. I migrate; It says the query is done and when I use it again the same query shows up.
我也尝试过使用 DoctrineMigrationsBundle，同样的查询显示需要完成。我迁移；它说查询已完成，当我再次使用它时，会出现相同的查询。
Does anybody have any idea how this is happening? I am stuck on this, so any help is greatly appreciated.
有人知道这是怎么回事吗？我坚持这一点，所以非常感谢任何帮助。

I had the same problem.
我有同样的问题。
Reason was - a newly created bundle was not yet added to app\config.yml.
原因是 - 尚未将新创建的包添加到app\config.yml.
Therefor all Entities in this new Bundle got never exported with php app/console doctrine:schema:update --dump-sql
因此，这个新捆绑包中的所有实体从未与 php app/console doctrine:schema:update --dump-sql
