我有一个基本视图，我在每个页面上使用。在我的基本观点中，我有：
<div class="container">
{% block body %}
{% endblock %}
</div>
每页的正文都来了。在我的基本视图中，我还有一个导航。现在我想根据登录用户的一些数据显示一个按钮。
这是我的情况：
我有一张表players，其中包含FK user_id和FK team_id。 user_id引用我的user表，其中保存了username, password, ...。现在我想根据球员表中的team_id显示按钮是否为NULL。
所以我需要这样的东西：
if(is_null($user->getPlayer()->getTeam())
{
// DON'T SHOW BUTTON
}
else{
// SHOW BUTTON
}
但我如何在基本视图中使用该数据？ （它在每一页上呈现）
更新：
我的用户实体：
