PSR-4代码库中的理论生成器的解决方法 [英] Workaround for doctrine generator in PSR-4 codebase

问题描述

使用Symfony 2&我正在尝试在Windows机器上的学说

With Symfony 2 & Doctrine on a Windows machine I'm trying to

1. 从现有架构生成实体：

1. generate entities from an existing schema:

php应用程序/控制台原则：mapping：import --force CoreBundle批注

为其生成getter / setter：

generate getters/setters on them:

php应用程序/控制台学说：generate：entities --path = / path / to / codebase / src / MyProject / CoreBundle / Entities CoreBundle

使用在其上生成REST CRUD控制器.com / voryx / restgeneratorbundle rel = nofollow> Voryx ：

php应用/控制台voryx：generate：rest- -entity = CoreBundle：User

第一步工作正常，我可以在我的CoreBundle / Entity文件夹中找到具有正确名称空间的实体：

The first steps works fine and I can find the entities in my CoreBundle/Entity folder with the correct namespace:

MyVendor\MyProject\CoreBundle\Entity

到目前为止很好。
但是，运行其他2条命令将失败：

Good so far. However, running the other 2 commands will fail:

[RuntimeException]
Can't find base path for "CoreBundle" (path: 
"\path\to\codebase\src\MyProject\CoreBundle", destination: 
"/path/to/codebase/src/MyProject/CoreBundle").  

composer.json中的自动加载看起来像这样：

The autoload in my composer.json looks like this:

"autoload": {
    "psr-4": {
        "MyVendor\\": "src/"
    }
},

我发现 Doctrine无法处理PSR-4名称空间，这可能是使其失败的原因。

I found out that Doctrine can't deal with PSR-4 namespaces, that's probably what makes it fail.

我真的希望这些实体住在PSR-4 CoreBundle中-有解决方法吗？

I would really like the entities to live in the PSR-4 CoreBundle though - is there a workaround for it?

我尝试了此方法，但是没有t工作，或者：

I tried this, but it doesn't work, either:

"autoload": {
    "psr-0": {
        "MyVendor\\MyProject\\CoreBundle\\Entity": "src/MyProject/CoreBundle/Entity/"
    },
    "psr-4": {
        "MyVendor\\": "src/"
    }
},

谢谢。

推荐答案

GitHub上的用户janvennemann为PSR-4固定了Doctrine。您可以找到 Gist补丁，或在下面链接到这里

User janvennemann on GitHub fixed Doctrine for PSR-4. You can find the patch on Gist, or linked here below

1. mkdir -p app / VendorOverride ;


2. cp vendor / doctrine / doctrine-bundle / Mapping / DisconnectedMetadataFactory.php app / VendorOverride / DisconnectedMetadataFactory.php ;
   
3. 应用DisconnectedMetadataFactory补丁；


4. 将 app / VendorOverride 添加到 composer.json 中的classmap 部分；


5. 运行 composer dump-autoload 。

1. mkdir -p app/VendorOverride;
2. cp vendor/doctrine/doctrine-bundle/Mapping/DisconnectedMetadataFactory.php app/VendorOverride/DisconnectedMetadataFactory.php;
3. apply the DisconnectedMetadataFactory patch;
4. add app/VendorOverride to the classmap section in composer.json;
5. run composer dump-autoload.

然后几乎所有脚手架命令都有效。

Then almost all scaffolding command works.
