http://symfony.com/doc/current/templating/app_variable.html:

    &lt;p&gt;Application Environment: {{ app.environment }}&lt;/p&gt;


Use

    app.environment

e.g.

    {% extends app.environment == &#39;dev&#39; ? &quot;::dev_layout.html.twig&quot; : &quot;::layout.html.twig&quot; %}

  

Or you can use

&lt;pre&gt;app.debug&lt;/pre&gt;

This returns true if debug is enabled. 
This is usually the case in the dev environment, however debug can be enabled in any of the environments... prod, test, dev, etc....

I&#39;ve seen `.S` files in various projects such as in the Linux Kernel, FreeBSD kernel, or in some other projects.  What do these files do and why can&#39;t we have `.c` files instead ?

How can I get this sort of thing to work?  I can check if `(obj instanceof List&lt;?&gt;)` but not if `(obj instanceof List&lt;MyType&gt;)`.  Is there a way this can be done?

Is there a way to get the name of the current environment in a Twig template? I&#39;d like to set some CSS style values depending on it.

I read [here][1] how to check the login status of an user by inside a twig template for a Symfony2-based website.
However, I need to know how to check if the user is logged in from inside a controller. I was quite sure the the following code was right:

    $user = $this-&gt;get(&#39;security.context&#39;)-&gt;getToken()-&gt;getUser();

but it always return something, e.g. a logged user or an anonymous user.

Any idea? Thanks in advance.

What&#39;s the difference between `Doctrine\Common\Persistence\ObjectManager` and `Doctrine\ORM\EntityManager` when using it in a custom form type?

I can get the respository using both `$this-&gt;em-&gt;getRepository()` and `$this-&gt;om-&gt;getRepository()`.

    class MyFormType extends \Symfony\Component\Form\AbstractType
    {

        /**
         * @var Doctrine\ORM\EntityManager
         */
        protected $em;
    
        public function __construct(Doctrine\ORM\EntityManager $em)
        {
            $this-&gt;em = $em;
        }

     }

Instead of:

    class MyFormType extends \Symfony\Component\Form\AbstractType
    {

        /**
         * @var Doctrine\Common\Persistence\ObjectManager
         */
        protected $om;
    
        public function __construct(Doctrine\Common\Persistence\ObjectManager $om)
        {
            $this-&gt;om = $om;
        }

     }

Is it possible to generate a single entity from database using the Symfony2 console tool?

In the middle of coding I had to add a table and there are modifications made to the existing entity classes. So I don&#39;t want all my entities regenerated. 

Any suggestions will be appreciated!

How to add more than one parameter in Twig path?&lt;br&gt;
Say you have this route :

    article_show:
        pattern:  /article/{slug}
        defaults: { _controller: AcmeArticleBundle:Article:show }

You can do this in your twig template :

    {{ path(&#39;article_show&#39;, { &#39;slug&#39;: article.slug }) }}

but what if you have this in your routing file:

    _files_manage:
        pattern: /files/management/project={idproject}&amp;user={iduser}
        defaults: { _controller: AcmeTestBundle:File:manage }

It looks like they didn&#39;t cover this in their documentation.




Add more than one parameter in Twig path

I&#39;ve created my own service and I need to inject doctrine EntityManager, but I don&#39;t see that `__construct()` is called on my service, and injection doesn&#39;t work. 

Here is the code and configs:

    &lt;?php

    namespace Test\CommonBundle\Services;
    use Doctrine\ORM\EntityManager;

    class UserService {
    
        /**
         *
         * @var EntityManager 
         */
        protected $em;
    
        public function __constructor(EntityManager $entityManager)
        {
            var_dump($entityManager);
            exit(); // I&#39;ve never saw it happen, looks like constructor never called
            $this-&gt;em = $entityManager;
        }
    
        public function getUser($userId){
           var_dump($this-&gt;em ); // outputs null  
        }
    
    }

Here is `services.yml` in my bundle

    services:
      test.common.userservice:
        class:  Test\CommonBundle\Services\UserService
        arguments: 
            entityManager: &quot;@doctrine.orm.entity_manager&quot;
    
I&#39;ve imported that .yml in `config.yml` in my app like that

    imports:
        # a few lines skipped, not relevant here, i think
        - { resource: &quot;@TestCommonBundle/Resources/config/services.yml&quot; }

And when I call service in controller

        $userservice = $this-&gt;get(&#39;test.common.userservice&#39;);
        $userservice-&gt;getUser(123);

I get an object (not null), but `$this-&gt;em` in UserService is null, and as I already mentioned, constructor on UserService has never been called

One more thing, Controller and UserService are in different bundles (I really need that to keep project organized), but still: everyting else works fine, I can even call

    $this-&gt;get(&#39;doctrine.orm.entity_manager&#39;)

in same controller that I use to get UserService and get valid (not null) EntityManager object.

Look like that I&#39;m missing piece of configuration or some link between UserService and Doctrine config.

I use Twig and I have an array with keys like this:

    array[1] = &quot;alpha&quot;
    array[2] = &quot;bravo&quot;
    array[3] = &quot;charlie&quot;
    array[8] = &quot;delta&quot;
    array[9] = &quot;echo&quot;

And I would like to get the key `(1,2,3,8,9)` and the content `(alpha, bravo, charlie, delta, echo)` in a loop to get all value of this array.

How do I solve this problem?

How to combine two string in twig?

I&#39;ve started to use Symfony2 but I&#39;ve some problems.
I wanted to render fields by hand but it doesn&#39;t work because my field yet rendered by me is displayed with the `form_rest()` function too, so I have two same fields.

Here is my code :

    &lt;div&gt;
         {{ form_errors(form.contenu) }}
         &lt;textarea id=&quot;{{ form.contenu.vars.id }}&quot; name=&quot;{{ form.contenu.vars.full_name }}&quot;&gt;{{ form.contenu.vars.value }}&lt;/textarea&gt;
    &lt;/div&gt;

And, at the form&#39;s end, I must put this :

    {{ form_rest(form) }}

But it displays the &quot;contenu&quot; field :(

Do you have an idea of what&#39;s the problem ?

How to make form_rest() not display a field with Symfony2?

I&#39;m working on a Symfony2 project which uses Twig, and the filetypes are `myfile.html.twig`. Vim doesn&#39;t automatically detect the syntax highlighting and so applies none. I can use `:set syntax=HTML` after I&#39;ve opened the file but this is a pain when jumping between files.

Is there a way to persistently set the syntax highlighting for a specific file type in vim?
