扩展外部TYPO3 extbase扩展的存储库 [英] Extend Repository of a foreign TYPO3 extbase extension

问题描述

我已经在TYPO3 6.2安装中安装了扩展名'femanager'，并成功地使用我自己的字段对其进行了扩展，这些字段可以从数据库中存储和读取.

I have installed the extension 'femanager' on a TYPO3 6.2 installation and successfully extended it with my own fields that get stored and read from the database.

现在，Controller中有一个操作，该操作调用UserRepository的findByUsergroup()方法，以使用过滤器呈现fe_users列表.

Now there is an action in a Controller that calls upon the UserRepository for the findByUsergroup() method to render a list of fe_users with a filter.

我想扩展搜索过滤器，因此必须从扩展名中更改方法findByUsergroup().这可能吗?如果可以，怎么办?

I want to extend the search filter, and therefore I must alter the method findByUsergroup() from my extension. Is this possible, and if so, how?

我一直在使用TYPO3进行很多开发，但没有使用extbase进行开发.我对钩子和信号/插槽以及这些种类很熟悉，但是我没有让它运行.有什么提示如何使TYPO3使用我的存储库来扩展femanager的存储库吗?

I have been developing a lot with TYPO3, but not with extbase. I am familiar with hooks and signal/slots and these kinds, but I don't get this running. Any hints how to make TYPO3 use my Repository that extends the one from femanager?

推荐答案

您可以使用TypoScript告诉extbase加载您的类，而不是原来的类

You can tell extbase to load your class instead of the original one with TypoScript

config.tx_extbase {
   objects {
      In2\Femanager\Domain\Repository\UserRepository {
         className = NGiB\Ngibmembers\Domain\Repository\MemberRepository
      }
   }
}

您仍然必须扩展原始类，但是现在应该调用您的repo.

You still have to extend the original class, but your repo should be called now.
