我是Symfony2的新手，我有一个问题，我自己无法完全解决。我正在编写应用程序并使用表客户端和项目。每个项目都有一个客户，每个客户都可以有多个项目。
客户端和projectstables的自主显示确实已经有效，但我还必须在客户的前端显示项目。我已经尝试了多种方法，但到目前为止我没有取得任何成功。
您能否告诉我我必须在ClientController-，config.yml和routing.yml-File中添加什么才能在客户的 show.html.twig文件中显示项目表？
我提前感谢您的回答

答案 0 :(得分：0)
如果您的实体关系配置正确（它们看起来像是什么），那么您可以在twig中访问项目数组direclty：
{% for project in entity.projects %}
Name: {{ project.name }}
...
{% endfor %}
