好的。这将是一个很长的帖子。很抱歉。
这是我复制您的问题的方法。
首先创建实体。我为此使用 yml，所以如果您使用注解，那么您的工作就是将 yml 样式转换为注解样式。
//AppBundle/Resource/config/doctrine/Annee.orm.yml

下一步是设置学说的方法。这些将在内部用于采取行动。
//AppBundle/Entity/Annee.php
//pay attention to the way addIndicateur(), removeIndicateur() methods are wrote. They are essential so that the many-to-many between Annee and Indicateur entities to work. The same for Indicateur.php and Partenaire.php

对于渲染，我使用了默认的 crud 表单，并添加了 novalidate 属性（适用于所有表单）：
{{ form_start(form,{attr:{'novalidate':'novalidate'}}) }}
我使用了默认的 CRUD 控制器和路由。如果您像我一样在为每个实体创建 CRUD 时使用 yaml，那么您需要将主 routing.yml 文件导入 app/config/routing.yml：
crud:
resource: '@AppBundle/Resources/config/routing.yml'
否则，如果您使用注释，则一切就绪。
