我正在为奏鸣曲管理员制作日历。我正在做它作为块服务。 所以我写了一个CalendarBlockService.php

和Calendrier.php（尚未完成）

我将服务声明为我的bundle / Resources / config / services.yml
sonata.block.service.calendrier:
class: CD\CarsBundle\Block\Service\CalendrierBlockService
arguments:
- "sonata.block.service.calendrier"
- '@templating'
- '@doctrine.orm.entity_manager'
- '@security.context'
- '@cd_cars.calendrier'
- '@cd_cars.jour'
tags:
- { name: sonata.block }
cd_cars.calendrier:
class: CD\CarsBundle\Service\Calendrier\Calendrier
cd_cars.jour:
class: CD\CarsBundle\Service\Calendrier\Jour
刷新页面时，出现以下错误消息：
在渲染模板期间抛出异常（“Catchable Fatal Error：传递给CD \ CarsBundle \ Service \ Calendrier \ Jour :: __ construct（）的参数1必须是DateTimeInterface的实例，没有给定，调用E：\ www \ flotte \ app \ cache \ dev \ appDevDebugProjectContainer.php在第815行并在SonataAdminBundle中定义了“）：核心：第42行的dashboard.html.twig。
所以，我知道缺少参数1，它应该是DateTime接口的一个实例。但是，我找不到我怎么写它。
请有人帮助我。
答案 0 :(得分：0)
您的体系结构中存在错误 - 服务应该是仅初始化（构造）一次然后在其他所有用例中重用的对象。因此，您无法使用datetime参数初始化Jour类，因为那样您的类将无法重复使用。 Jour似乎不是一种服务。
