Php 在基本视图（细枝）和#x2B中使用数据库中的数据；symfony2

我有一个基本的视图，我在每一页上都使用它。我的基本观点是：

<div class="container">
    {% block body %}
    {% endblock %}
</div>

但是我如何在我的基本视图中使用这些数据呢？（每页都会呈现）

更新：
我的用户实体：

当前登录的用户存储在twig全局变量
app.user

{% if app.user.player.team %}
    show button
{% else %}
    not
{% endif %}

然后我得到了这个错误：不可能访问空变量（“”）上的属性（“myteam”），但是玩家总是空的，而且当一个玩家有一个用户ID时，你的关系就被破坏了。我不得不添加player和getPlayer（），setPlayer（）因为自动生成的映射没有添加它，所以我将自己添加到用户实体。但它仍然提供NULL。。我将我的用户实体添加到我的开始帖子中。
{% if app.user.player.team %}
    show button
{% else %}
    not
{% endif %}
