安装QCMBundle-Override服务

Question

我正在尝试安装qcm软件包https://github.com/avoo/QcmCoreBundle，我不明白在这一步中我必须做什么：

覆盖服务

qcm_core:
    service:
        statistics:
            class: MyBundle\Statistics\Class // For better compatibility extends the Model\QuestionnaireStatistics
            template: MyBundle\Answers\Template\Class // You need to implements the qcm TemplateInterface

此错误是否由此步骤引起

[Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException]  
  The service "qcm_core.form.type.user" has a dependency on a non-existent pa   
  rameter "qcm_core.model.user.class". Did you mean one of these: "fos_user.m   
  odel.user.class", "qcm.model.user.class", "qcm_core.template.class", "qcm_c   
  ore.controller.user.class", "qcm_core.form.type.user.class"?  

Answer 1

如果要覆盖服务，则缺少缩进：

qcm_core:
    service:
        statistics:
            class: MyBundle\Statistics\Class // For better compatibility extends the Model\QuestionnaireStatistics
            template: MyBundle\Answers\Template\Class // You need to implements the qcm TemplateInterface
