One solution is to shuffle your collection of rows using php

      public function getRandom($max = 10,$site) {
        $results = $this->createQueryBuilder('u')
                ->where('u.site = :site')
                ->setParameter('site', $site)
                ->orderBy('u.sort', 'DESC')
                ->setMaxResults($max)
                ->getQuery()
                ->getResult();
        shuffle($results);
        return $results;
    }

In this solution, you retrieve the last 10 rows and shuffle them after. Peformances are not too bad but you will always retrieves the same last rows from your table.

Another solution is to use the array_rand php fonction

      public function getRandom($site) {
        $results = $this->createQueryBuilder('u')
                ->where('u.site = :site')
                ->setParameter('site', $site)
                ->orderBy('u.sort', 'DESC')
                ->getQuery()
                ->getResult();
        $result2 = array_rand($results);
        return $result2;
    }

In this case you fetch all rows from your table, this could be slow and memory consuming…

If you need to retrieve only one row, you can use somethinfg like this

 public function getOneRandom()
{
$em = $this->getEntityManager();
$max = $em->createQuery('
SELECT MAX(q.id) FROM questions q
')
->getSingleScalarResult();
return $em->createQuery('
SELECT q FROM questions q
WHERE q.id >= :random
ORDER BY q.id ASC
')
->setParameter('random',rand(0,$max))
->setMaxResults(1)
->getSingleResult();
}

This solution can only be used if you want to retrieve any of the tables rows, if you add a filtrer you may return an empty result.

This solution is not dirty it just use 2 queries instead of one. the tips is to use the offset. And you can use a filter !!!

$qCount = Doctrine::getTable('Questions')
     ->createQuery()
     ->select('count(*)')
     ->where('site = :site')
     ->setParameter('site', $site)
     ->fetchOne(array(), Doctrine::HYDRATE_NONE);
$question = Doctrine::getTable('Questions')
     ->createQuery()
     ->select('*')
     ->where('site = :site')
     ->setParameter('site', $site)
     ->limit(1)
     ->offset(rand(0, $qCount[0] - 1))
     ->fetchOne();

And you still can use native queries : http://docs.doctrine-project.org/en/latest/reference/native-sql.html

Fatal error: Declaration of Adin\AdminBundle\Admin\AnnonceAdmin::validate() must be compatible with that of Sonata\AdminBundle\Admin\AdminInterface::validate() in /home/www/arlogis/src/Adin/AdminBundle/Admin/AnnonceAdmin.php on line 250

Don’t panic, just add this at the begining of your class

use Sonata\AdminBundle\Validator\ErrorElement;

in our example it’s in this file : /AdminBundle/Admin/AnnonceAdmin.php

The post Fatal error : Declaration of {{path}}::validate() must be compatible with that of Sonata\AdminBundle\Admin\AdminInterface::validate() appeared first on Agence de Développement Informatique du Nord.

On your entity class, for example AdminBundle/Entity/Annonce.php, add the HasLifecycleCallbacks annontation

/**
 * @ORM\Entity(repositoryClass="Tripix\AdminBundle\Repository\AnnonceRepository")
 * @ORM\HasLifecycleCallbacks
 */

And your method, with the annotation

/** @ORM\PreUpdate() */
        public function preUpdate()
        {
                $this->created_at = new \DateTime("now");
        }

That’s all, it should works.

A complete example, just in case :

<?php
namespace Tripix\AdminBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\Common\Collections\ArrayCollection;


/**
 * @ORM\Entity(repositoryClass="Tripix\AdminBundle\Repository\AnnonceRepository")
 * @ORM\HasLifecycleCallbacks
 */
class Annonce
{

/** @ORM\PreUpdate() */
        public function preUpdate()
        {
                $this->created_at = new \DateTime("now");
        }

    public function __construct()
    {
        $this->created_at = new \DateTime("now");
        $this->visuels = new ArrayCollection();
    }

The post Doctrine2 override save method appeared first on Agence de Développement Informatique du Nord.

First, override the controller action method, in your AdminBundle/Controller/SecteurAdminController.php file

 /**
     * return the Response object associated to the list action
     *
     * @return Response
     */
    public function listAction()
    {
        if (false === $this->admin->isGranted('LIST')) {
            throw new AccessDeniedException();
        }

        $datagrid = $this->admin->getDatagrid();
        $formView = $datagrid->getForm()->createView();

        // set the theme for the current Admin Form
        $this->get('twig')->getExtension('form')->setTheme($formView, $this->admin->getFilterTheme());

        //custom code from here
        $total = 0;
        $enable = 0;
        $new = 0;
        $site = $this->admin->site;

        $repository = $this->getDoctrine()->getRepository('TripixAdminBundle:Annonce');
        $total = $repository->getNombreAnnonceTotal($site);
        $enable = $repository->getNombreAnnonceEnabled($site);
        $new = $repository->getNombreAnnonceNew($site);



        return $this->render('TripixAdminBundle:CRUD:list_secteur.html.twig', array(
            'action'   => 'list',
            'form'     => $formView,
            'datagrid' => $datagrid,
            'total'     => $total,
            'enable'    => $enable,
            'new'       => $new,
        ));
    }

The import thing on previous code is the render() fonction, the first parameter is the template to use.
In our example, the template file will be /AdminBundle/Ressources/view/CRUD/list_secteur.html.twig

You can use the /AdminBundle/Ressources/view/CRUD/base_secteur.html.twig file as example for your custom template.

Parent function to override on the controller are here : /vendor/bundles/Sonata/AdminBundle/Controller/CRUDController.php

The post Symfony2 sonata custom CRUD template appeared first on Agence de Développement Informatique du Nord.

On your admin class file (ex: /AdminBundle/Admin/SecteurAdmin.php), on your configureListFields() fonction, add a new entry on the listMapper object

    /**
     * @param \Sonata\AdminBundle\Datagrid\ListMapper $listMapper
     * @return void
     */
    protected function configureListFields(ListMapper $listMapper) {
        $listMapper
                ->addIdentifier('titre')
                ->add('Tri', 'string', array('template' => 'TripixAdminBundle:Admin:list_tri.html.twig'))
                ->add('Nb', 'string', array('label' => 'Nombre d\'annonce(s)', 'template' => 'TripixAdminBundle:Admin:list_nb_annonce.html.twig'))
                ->add('_action', 'actions', array(
                    'actions' => array(
                        'edit' => array(),
                        'delete' => array(),
                    )
                ))
        ;
    }

This new entry said to use the TripixADminBundle:Admin:list_tri.html.twig template.

Now, create your template file (list_nb_annonce.html) in the /AdminBundle/ressources/view/admin/ directory.

{% extends 'SonataAdminBundle:CRUD:base_list_field.html.twig' %}

{% block field%}
{% if admin.datagrid.results|length > 1 %}
 <div>
        <strong>{{ object.getNombreAnnonce}}</strong>
    </div>
{% endif %}
{% endblock %}

In our example, getNombreAnnonce() is not defined, let’s do it
In the /adminBundle/Entity/Secteur.php file, add

   public function getNombreAnnonce()
    {
      return count($this->getAnnonces());
    }

That’s all.

function validate(ErrorElement $errorElement, $object)

Then, you get this error :

Fatal error: Declaration of Adin\AdminBundle\Admin\AnnonceAdmin::validate() must be compatible with that of Sonata\AdminBundle\Admin\AdminInterface::validate() in /home/www/arlogis/src/Adin/AdminBundle/Admin/AnnonceAdmin.php on line 251 

You checked to AdminInterface file the declaration is the same.

To fix it, you need to use additionnal namespace :

use Sonata\AdminBundle\Validator\ErrorElement;
use Symfony\Component\Validator\ValidatorInterface;

I will show you here how to define a new function for twig.

On your namespace/bundle, add a Twig/Extension directory and create your class file :
/src/Adin/ArlogisBundle/Twig/Extension/FileExistsExtension.php

<?php

namespace Adin\ArlogisBundle\Twig\Extension;

class FileExistsExtension extends \twig_Extension
{
        /**
         *Return the function registered as twig extension
         *
         *@return array
         */
        public function getFunctions()
        {
                return array(
                        'file_exists' => new \Twig_Function_Function('file_exists'),
                        );
        }

        public function getName()
        {
                return 'adin_file_exists';
        }
}
?>

You then have to register your service, add a in your /Adin/ArlogisBundle/Ressources/config/services.xml file

<?xml version="1.0" ?>

<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
<services>
       <service id="adin.twig.tripix_extension" class="Adin\ArlogisBundle\Twig\Extension\FileExistsExtension">
        <tag name="twig.extension" />
        </service>
    </services>
</container>

It’s ready, you can use it on your twig template

{% if file_exists('/var/www/image.jpg') %}
    File exists
{% else %}
    File not exists
{% endif %}

Be carefull, you need to specify the absolute path of the file. You can create a twig global variable root_path.
app/config/config.yml

# Twig Configuration
twig:
    globals:
        root_path: %kernel.root_dir%/../web

Then on twig template

{% if file_exists({{root_path}}'/var/www/image.jpg') %}
    File exists
{% else %}
    File not exists
{% endif %}

this issue may be a rights problem on your cache drectory. By default, gregwar cache directory is on your web so, launch this command

chmod 777 web/cache

This error may also occur if the file doesn’t exist, for a clean code, add

{% if file_exists('uploads/' ~ site.id ~ '.jpg') %}
    {{ image(site.picture).resize(250, 50) }}
{% endif %}

or on twig code

{% if site.has_picture %}

You need to enable either the SQLite3 or PDO_SQLite extension for the profiler to run properly.

It probably means you need to install the sqlite extension for php

apt-get install php5-sqlite

restart apache and that should to the tricks.
