Symfony2.7 Twig How to obtain a token? - symfony

Inside Twig file I have this code:
{% set player = app.security.getToken().getUser().getPlayer() %}
{% if player.getSelectedCharacter() is not null %}
{% set character = player.getSelectedCharacter() %}
{% .... %}
{% endif %}
But at now, app.security is deprecated. So I want to change this. I can obtain user token inside my controller and send it to the Twig. But I prefer to get it directly via Twig.
How I can do this?

As you said and mentioned in the documentation.
The app.security global is deprecated as of 2.6. The user is already
available as app.user and is_granted() is registered as function.
I think you can just try something like this in your view.
app.user.getPlayer()

twig dynamic translation domain

I'm trying to translate user content, using a translation domain depending on the role of the user.
here is my code:
{% if is_granted('ROLE_TEACHER') %}
{% set translation_domain = 'ROLE_TEACHER' %}
{% else %}
{% set translation_domain = 'ROLE_PARENT' %}
{% endif %}
<h5>{{"Main Title"|trans({}, translation_domain) }}</h5>
This works perfect for a user, in browser.
However the command for generating the translations (bin/console translation:extract en) generates them for the 'undefined' translation domain.
Is there a better way? Any ideas?
Whats the standard way for doing this? I cant seem to find any docs.

How to use twig object variable with at-sign # inside

I send from Symfony object which contains at-sign # in variable.
Object name is invoice and with {{ dump(invoice) }} in twig template I see object and parameter with path:
invoice[0].banSpojDod#showAs
But I dont know how to get value of this banSpojDod#showAs because there is at-sign #.
Could you help me someone please?
You could try with The attribute function can be used to access a "dynamic" attribute of a variable:
{{ attribute(invoice[0], 'banSpojDod#showAs') }}
Hope this help
Ok thanks. Problem was that I used it in loop, and some parameters not exists. I needed to add exist conditions. So my final code works:
{% for f in invoice %}
{% if attribute(f,'banSpojDod#showAs') is defined %}
{{ attribute(f,'banSpojDod#showAs') }}
{% endif %}
{% endfor %}

Symfony2 anon. access attribute on app.user in twig when app.user is null

When user is not logged app.user is null - i know that.
I've got a section in my twig template that is used to check for notifications.
{% if app.user.notificationsNews == 1 %}
<span class="challenge-notify animated rotateIn">!</span>
{% endif %}
no user, no notifications, no problem. Except well the user is null and it still wants to access the attribute
Impossible to access an attribute ("notificationsNews") on a null
variable
is there a good way to bypass that? |default doesn't do the trick
I could check that in my controller and return a different template file, I just want to know if there is a way to do this in twig.
You should be good to go with this
{% if app.user and app.user.notificationsNews == 1 %}
<span class="challenge-notify animated rotateIn">!</span>
{% endif %}
If you are as lazy as me, you can use the |default filter:
{% if app.user.notificationsNews|default(0) == 1 %}
<span class="challenge-notify animated rotateIn">!</span>
{% endif %}

twig convert a string to the object that it represent

imaging that i have a object and which can be called in a twig template like this:
{{ object1.object2.object3.property3A }}
well, it will show me the content if we use php to write is :
$object1->getObject2()->getObject3()->getProperty3A();
My question is if i have a string ,
$refString="object1.object2.object3.property3A";
and then it is passed to twig, how could i get the property3A? For my experience, we can do this in php like this:
$refString="object1->getObject2()->getObject3()->getProperty3A()";
echo $$refString;
But i do not know how to make it work in twig.
I didn't tested this, but i think it schould do the trick.
{#
recursively reading attributes from an object
! object1 must be available !
theValue is the value of property3A
#}
{% for key in "object1.object2.object3.property3A"|split('.') %}
{% if not loop.first %}{# skip the 'object1' part #}
{% set theValue = attribute(theValue|default(object1), key) %}
{% endif %}
{% endfor %}
I don't think there is a "shortcut" to do this in twig. If you can't find a simple way to do this, you can write you own extension, that would convert a STRING_TYPE to a VAR_TYPE.
Twig internals might put you on the right track. This is an example of what is feasable with twig extension and might inspire you.
I ran into a similar situation. This answer will only work if the object you need is available to the template and you know the name of it with a string.
In this case, you can access the object using Twig's Global Variable _context:
{% set object1 = _context['object1'] %}
And then access the methods and variables of the object as normal:
{{ object1.object2.object3.property3A }}

symfony2 - twig - how to render a twig template from inside a twig template

I have a xxx.html.twig file which shows a page, but when I want to refresh the page with different data and just update it with new data, I have a select and a submit button for it.
The thing is that I don't know how do I call an action in the controller which I pass parameters to from my twig and call for new data and then I render the same twig template again with new parameters.
How do I do so?
Here are a few different ways:
{{ render(app.request.baseUrl ~ '/helper/test', {"hostid2": hostid } ) }}
or
{% include 'MyCoreBundle:Helper:test.html.twig' with {"hostid2": hostid } only %}
or
{% render controller("MyCoreBundle:Helper:test", {'hostid2': hostid}) %}
Symfony 2.1:
{% render 'YourBundle:YourController:yourAction' with {'var': value} %}
Symfony 2.6+:
{{ render(controller('YourBundle:YourController:yourAction', {'var': value})) }}
And, of course, read the documentation.
I think some parts are depricated here.
To make the include work in latest Symfony 3.1.10, I solved it like this:
{% extends 'base.html.twig' %}
{% block body %}
{{ include('AppBundle:Default:inner_content.html.twig') }}
{% endblock %}
Note: include() with parentheses.
Then all the variables are included from the parent template. If you like to restrict some variables in the child template, you use with ... only (look over)
