如何在Doctrine的Apigile应用程序中同时使用多个版本？ [英] How to use multiple versions at the same time in an Apigility app with Doctrine?

问题描述

上下文： Apigility 驱动的应用程序基于 Zend Framework 2 。在第一个版本（ V1 ）中，我使用的是 ZfcBase DbMapper 。现在，我正在使用教条2 V2 >作为ORM。

Context first: Apigility driven application based on Zend Framework 2. In the first version (V1) I was using the ZfcBase DbMapper for the model layer. Now I'm implementing the V2 with Doctrine 2 as ORM.

Apigility提供了一个简单的版本切换，每个版本都可以使用自己的DB适配器：

Apigility provides an easy switching between versions and every version can use its own DB adapter:

/config/autoload/global.php / /config/autoload/local.php

/config/autoload/global.php / /config/autoload/local.php

<?php
return array(
    ...
    'db' => array(
        'adapters' => array(
            'DB\\myproject_v1' => array(
                // settings (driver, hostname, database, driver_options)
                // credentials (username, password)
                ...
            ),
            'DB\\myproject_v2' => array(
                // settings (driver, hostname, database, driver_options)
                // credentials (username, password)
                ...
            ),
        ),
    ),
    ...
);

所以，要使用另一个版本作为默认的另一个数据库，它只需要更改URL：

So, to use another version as default with another database behind it only the URL needs to be changed:

myproject.tld/my-endpoint    <-- version set to default
myproject.tld/v1/my-endpoint <-- version 1
myproject.tld/v2/my-endpoint <-- version 2

我想添加Doctrine 2到我的应用程序，所以我扩展了我的 local.php 像 here 显示：

I want to add Doctrine 2 to my application, so I extended my local.php like here shown:

<?php
return array(
    ...
    'doctrine' => array(
        'connection' => array(
            'orm_default' => array(
                'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
                'params' => array(
                    // settings (host, port, dbname)
                    // credentials (user, password)
                    ...
                ),
            ),
        ),
    ),
    ...
);

它的工作，但现在我没有灵活性在版本之间切换/使用不同的具有不同数据库的版本。我的适配器设置被教条连接配置覆盖或被忽略了。

It's working, but now I don't have the flexibility for switching between the versions / for using different versions with different databases behind them. My adapter settings are getting overridden by the doctrine connection configs or just ignored.

如何将Doctrine与Apigility的版本控制灵活性相结合？如何在Doctrine的Apigility应用程序中配置数据库连接，并且能够同时在各个版本之间切换/使用多个版本？

推荐答案

您的配置的以下部分：

[
    'db'=>[
        'adapters' => [
            'DB\\myproject_v1' => [],
            'DB\\myproject_v2' => [],
        ]
    ]
]

工厂用db适配器实例注册服务名称 DB\\myproject_v1 和 DB\\myproject_v2 。

configures an abstract factory that registers the service names DB\\myproject_v1 and DB\\myproject_v2 with db adapter instances.

下面的配置部分实际上将适配器分配给数据库连接的资源：

It is the part of the configuration below that actually assigns the adapter to your DB connected resource:

'db-connected' => array(
    'YourDBConnectedResource' => array(
        'adapter_name'     => 'DB\\myproject_v1',
    ),
),

Doctrine提供了自己的抽象工厂和配置，所以要让Apigility与Doctrine一起作为数据库适配器，你只需要调整配置有点。首先，让我们添加一个第二个连接到你的doctrine配置来帮助说明这个变化。

Doctrine provides its own abstract factory and configuration, so to make Apigility work with Doctrine as your database adapter, you just have to tweak the configuration a bit. First, lets add a second connection to your doctrine config to help illustrate the change.

return [
    'doctrine' => [
        'connection' => [
            'orm_default' => [ // you don't have to use orm_default, you can arbitrarily name this version1
                'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
                'params' => [
                    // settings (host, port, dbname)
                    // credentials (user, password)

                ],
            ],
            'version2' => [
                'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
                'params' => [
                    // settings (host, port, dbname)
                    // credentials (user, password)
                ],
            ],            
        ],
    ],
];

现在，您的数据库适配器名称为 doctrine.connection.orm_default 和 doctrine.connection.version2 。所以你替代你的数据库连接的配置块中的那些。

Now, your DB adapter names are doctrine.connection.orm_default and doctrine.connection.version2. So you substitute those in your db-connected configuration block.

'db-connected' => [
    'My\\Endpoint\\V1\\Rest\\MyResource' => [
        'adapter_name'     => 'doctrine.connection.orm_default',
    ],
    'My\\Endpoint\\V2\\Rest\\MyResource' => [
        'adapter_name'     => 'doctrine.connection.version2',
    ],
],
