The notation you&#39;re showing us is for defining and rendering a block. Rendering only is done this way:

    {{ block(&#39;blockName&#39;) }}

I&#39;m accustomed to running a git comparison that will allow comparison with local git revs like:

    git diff HEAD HEAD~110 -- some/file/path/file.ext

Is it possible to use the date instead? And if so, how? I would like to be able insert in place of the &quot;110&quot; in the above example, a date such as &quot;4 Dec 2012&quot;.

git diff on date?

How can I render a block multiple times within a view in a twig template? Currently I do have a block, let&#39;s call it `something` defined in an included (via `render `) twig file. I then include it at the layout-twig file using the following:

    {% block something %}{% endblock %}

Everything is fine, however as soon as I call this tag a second time, I get the following error message:

    The block &#39;something &#39; has already been defined in &quot;::layout.html.twig&quot; 

Therefore: How can I render a block multiple times?

I am using Doctrine2 migrations. I need some answers about my doubt, I canno find a good solution in documentations

I use:

      doctrine migrations:diff // generate migrations files
      doctrine migrations:migrate // migrates up to new version

1. How Can I migrate down? specifying the previous version did not work ( nothing to update it says f.e. doctrine migrations:migrate Version20120211163332 it says 

        Migrating up to Version20120211163332 from 20120309112058
                                                
        [Doctrine\DBAL\Migrations\MigrationException]  
        Could not find any migrations to execute.      

 But it&#39;s not up it should be down! you can see also on versions in response

2. If I have to make some DB update, is it possible to add some SQL Queries in additions ( alter some datas related to other) ?  I have not tried still since the down is not working :((

3. Is there any way to use the migrate command in a browser nutshell ? I have sw in a shared  hosting without console access so I need this feature, instead of copying queries one by one :D in phpMyAdmin




Doctrine2 migrations migrate down and migrate from browser and not command line

In Symfony 2 templates (using Twig), how can I effectively check whether a user is not logged in?

I don&#39;t want to use `ROLE` checks. I want a straightforward way to check if a user is not logged in.

I&#39;m aware that comparing `app.user.username` with `anon` works, but that just doesn&#39;t feel right to me.

Symfony 2: How do I check if a user is not logged in inside a template?

An `User` has one `Package` associated with it. Many users can refer to the same package. `User` cannot exists without a `Package` defined. `User` should own the relation. Relation is bidirectional, so a `Package` has zero or more users in it. 

These requirements lead to `ManyToOne` relation for `User` and `OneToMany` relation of `Package` in Doctrine 2. However `package_id` in `user` table (that is foreign-key) allows `null` values. I&#39;ve tried setting `nullable=false` but command:

     php app/console doctrine:generate:entities DL --path=&quot;src&quot; --no-backup

Says that there is no attribute `nullable` for the relation `ManyToOne`. **What i&#39;m missing?**

    class User
    {
    
        /**
         * @ORM\Id
         * @ORM\Column(type=&quot;integer&quot;)
         * @ORM\GeneratedValue(strategy=&quot;AUTO&quot;)
         */
        private $id;
    
        /**
         * @ORM\ManyToOne(targetEntity=&quot;Package&quot;, inversedBy=&quot;users&quot;)
         */
        private $package;
    
    }

    class Package
    {
    
        /**
         * @ORM\Id
         * @ORM\Column(type=&quot;integer&quot;)
         * @ORM\GeneratedValue(strategy=&quot;AUTO&quot;)
         */
        private $id;
    
        /**
         * @ORM\OneToMany(targetEntity=&quot;User&quot;, mappedBy=&quot;package&quot;)
         */
        private $users;
    
    }

Doctrine 2 can&#39;t use nullable=false in manyToOne relation?

I am very new to symfony. In other languages like java and others I can use `request.getParameter(&#39;parmeter name&#39;)` to get the value.

Is there anything similar that we can do with symfony2.   
I have seen some examples but none is working for me. Suppose I have a form field with the name **username**. In the form action I tried to use something like this:

    $request = $this-&gt;getRequest();
    $username= $request-&gt;request-&gt;get(&#39;username&#39;); 

I have also tried 


`$username = $request-&gt;getParameter(&#39;username&#39;);` 

and

    $username=$request-&gt;request-&gt;getParameter(&#39;username&#39;);

But none of the options is working.However following worked fine:

    foreach($request-&gt;request-&gt;all() as $req){
   	    print_r($req[&#39;username&#39;]);
    }

Where am I doing wrong in using `getParameter()` method. Any help will be appreciated.

i&#39;m building a mobile app talking to my symfony2 app via webservices
I can&#39;t find a way to disable csrf protection on a specific controller/action

i want to post registration data to this action and use sf2 form validation. I do not call the form in my mobile app

Can&#39;t change container parameters in action, throw an exception because it is a frozen parameter...

I do not want to disable form protection for whole my application

any clue ?

thanks !


**update: with symfony 2.1.x**

    /**
     * {@inheritdoc}
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver-&gt;setDefaults(array(
            &#39;csrf_protection&#39;   =&gt; false,
        ));

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 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.
