php - Symfony2/Doctrine2 中的枚举启用问题

Question

作为我的问题的序言，我已经尝试了 this StackExchange question 建议的所有解决方案.

这是给出的错误:

[Doctrine\DBAL\DBALException]
Unknown column type "enumAddressSource" requested. Any Doctrine type t
hat you use has to be registered with \Doctrine\DBAL\Types\Type::addTy
pe(). You can get a list of all the known types with \Doctrine\DBAL\Ty
pes\Type::getTypesMap(). If this error occurs during database introspe
ction then you might have forgot to register all database types for a
Doctrine Type. Use AbstractPlatform#registerDoctrineTypeMapping() or h
ave your custom types implement Type#getMappedDatabaseTypes(). If the
type name is empty you might have a problem with the cache or forgot s
ome mapping information.

此错误与我在尝试任何修复之前收到的错误相同。

这是 config.yml 文件中的当前 Doctrine 代码:

doctrine:
    dbal:
        driver:   pdo_mysql
        host:     "%database_host%"
        port:     "%database_port%"
        dbname:   "%database_name%"
        user:     "%database_user%"
        password: "%database_password%"
        charset:  UTF8
        mapping_types:
            enum: string
            enumAddressSource: string
            # if using pdo_sqlite as your database driver:
            #   1. add the path in parameters.yml
            #     e.g. database_path: "%kernel.root_dir%/data/data.db3"
            #   2. Uncomment database_path in parameters.yml.dist
            #   3. Uncomment next line:
            #     path:     "%database_path%"

    orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true

vendor/doctrine/dbal/lib/Doctrine/DBAL/Platforms/MySqlPlatform.php下的相关代码:

protected function initializeDoctrineTypeMappings()
{
    $this->doctrineTypeMapping = array(
        'tinyint'       => 'boolean',
        'smallint'      => 'smallint',
        ...
        'enum'          => 'string',
        'enumAddressSource' => 'string',
    );

我会尝试采纳这里显示的建议:Doctrine Cookbook ，但是文章并没有明确说明这段代码要注入(inject)到哪个文件中(特指方案一)。在我看来，显示的代码将被第二个代码示例底部注入(inject)的代码覆盖。

数据库中的所有枚举都会发生这种情况。手动更改数据库不完全是一种选择。我还能尝试什么？

不确定的目的:enumAddressSource: string

难道 enum: string(如前一行)就足够了吗？

您收到的错误消息基本上是告诉您没有名为“enumAdressSource”的类型，因此没有此类类型可以映射到字符串。您映射的是类型，而不是此处的字段。
