Get username in Symfony (in Twig) on page, which is accessible to anonymous users

Question

Is there a way to access username of the logged user on page, which is accessible to anonym users in Symfony 2.6.1?

Example: I have main page, where is link to login and if there is a user logged in, I want to display his username as a link to his account instead of the login link.

If I use {{ app.user.username }} it will display error

Impossible to access an attribute ("username") on a NULL variable ("")

because app.user is null object on pages with security: false defined is security.yml. It will work only on pages, which needs to be under firewall with no security: false.

Im not sure if i understood your problem correctly, but its true that {{ app.user.username }} throws an exception, because there is not user object if you are not logged in. So just check if the object exists:

{% if app.user is defined %}
    {# link to account #} 
{% else %}
    {# link to login #}
{% endif %}

If this hint is not the exspected one, give us some code.

But I want to get username even if "app.user" is not defined. Is it possible? – H.W. Mar 03 '15 at 12:28
Then you have to get the user object by id. Something like `$this->getDoctrine()->getRepository('User')->find($id)`. – 4lxndr Mar 03 '15 at 13:20

You should try something like this:
set a default value for anonymous :

{{ app.user.username|default('Not Logged') }}
