Use data from database in base view (twig) + symfony2 - php

Question

I have a basic view that I use on every page. In my basic view I have:
<div class="container">
{% block body %}
{% endblock %}
</div>
Where the body of every page comes. In my base view I have also a navigation. Now I would like to show a button depending on some data of the user logged in.
This is my case:
I have a table players with a FK user_id and a FK team_id. The user_id refers to my user table where the username, password, ... is saved. Now I would like to show the button depending on team_id in players table is NULL or not.
So I would need something like this:
if(is_null($user->getPlayer()->getTeam())
{
// DON'T SHOW BUTTON
}
else{
// SHOW BUTTON
}
But how I can use that data in my base view? (It's rendered on every page)

The current logged in user is stored in the twig global variable app.user
{% if app.user.player.team %}
show button
{% else %}
not
{% endif %}
