在Symfony中重写父服务参数并将更多参数添加到子级的正确方法是什么?根据文档,我需要使用“ index_N”。但是如何为子服务添加更多参数呢?例如:
服务: #...
App\Repository\DoctrineUserRepository:
parent: App\Repository\BaseDoctrineRepository
# overrides the public setting of the parent service
public: false
# appends the '@app.username_checker' argument to the parent
# argument list
arguments: ['@app.username_checker']
App\Repository\DoctrinePostRepository:
parent: App\Repository\BaseDoctrineRepository
# overrides the first argument (using the special index_N key)
arguments:
index_0: '@doctrine.custom_entity_manager'
// put here more arguments for the child service
答案 0 :(得分:1)
未经测试,但您是否尝试过使用“命名参数”,例如:
# overrides the first argument (using the special index_N key)
# and set named argument $usernameChecker
arguments:
index_0: '@doctrine.custom_entity_manager'
$usernameChecker: '@app.username_checker'
