Symfony2项目，使用树枝模板设计的问题

Question

I have a doubt about templates using twig, my problem is the following, I have a page called index.html.twig, which extends from base.html.twig. In index.html.twig there are two include blocks, (one is for the upper menu bar; a navbar and the other one corresponds to the footer) My navbar contains the following options for anonymous users,

--Login--Register--Contact--

Now, if I sign in, I wanted to load a different navbar instead of the previous one, for example

--You're signed as Blablabla-- Edit profile -- Exit --

How can I accomplish this? I mean, to include different blocks based on a session. Do I have to check in the view if the user is logged in? Or do I have to check in the controller if the user has session and then load a different index.html.twig(one for logged in users.) In relation with the last option, I can create an index.html.twig, and an indexLoggedIn.html.twig, and in the controller I can check, if the user is logged in I render indexLoggedIn, otherwise I load index.html.twig. I used the FOSUserBundle for user management. Thanks!

You could do something like this:

{% if app.user and is_granted("IS_AUTHENTICATED_REMEMBERED") %}
  {{ include('FooBarBundle:Navbar:authenticated.html.twig') }}
{% else %}
  {{ include('FooBarBundle:Navbar:anonymous.html.twig') }}
{% endif %}

See the documentation about when to check for IS_AUTHENTICATED_REMEMBERED and when to use IS_AUTHENTICATED_FULLY. And see one of the many other SO posts for more hints.
