使用Sonata Admin Bundle更改xls导出中的日期格式

Question

I taken over responsibility for a Symfony2 application, built on the Sonata Admin Bundle , and have been asked to make a small change by the users. In the xls export of a list page, the dates all appear as eg Wed, 01 Aug 2012 00:00:00 +0200 , but the Excel format is General . The users would like the data in this column to be an Excel date type, so that it is sort-able.

I have been able to find some information about export customization, but this mostly concerns choosing the list export file types, or which fields to include, rather than how to change the format in the exported document. A similar question was asked here (I think) but there is no answer.

I think this would (or should) be very simple, but it is certainly not obvious. Any help would be much appreciated.

Answer 1

A small improvement for Marciano's answer. Makes the code a bit more resilient against sonata updates.

public function getDataSourceIterator()
{
    $datasourceit = parent::getDataSourceIterator();
    $datasourceit->setDateTimeFormat('d/m/Y'); //change this to suit your needs
    return $datasourceit;
}

Answer 2

this is my code. It's work!

use Exporter\Source\DoctrineORMQuerySourceIterator;
use Sonata\DoctrineORMAdminBundle\Datagrid\ProxyQuery;
use Sonata\AdminBundle\Datagrid\ProxyQueryInterface;

and function:

/**
 * {@inheritdoc}
 */
public function getDataSourceIterator()
{

    $datagrid = $this->getDatagrid();
    $datagrid->buildPager();
    $fields=$this->getExportFields();
    $query = $datagrid->getQuery();


    $query->select('DISTINCT ' . $query->getRootAlias());
    $query->setFirstResult(null);
    $query->setMaxResults(null);



    if ($query instanceof ProxyQueryInterface) {
        $query->addOrderBy($query->getSortBy(), $query->getSortOrder());

        $query = $query->getQuery();
    }


    return new DoctrineORMQuerySourceIterator($query, $fields,'d.m.Y');
    }

Answer 3

just add this in your admin (overriding a method of the admin class you are extending). Found it reading the code. It's not in the docs.

public function getDataSourceIterator()
{
    $datagrid = $this->getDatagrid();
    $datagrid->buildPager();

    $datasourceit = $this->getModelManager()->getDataSourceIterator($datagrid, $this->getExportFields());
    $datasourceit->setDateTimeFormat('d/m/Y'); //change this to suit your needs

    return $datasourceit;
}

Answer 4

In my admin class EmployeeAdmin I use getExportFields function specifies which fields we want to export:

   public function getExportFields() {
       return array(
            $this->trans('list.label_interview_date') => 'interviewDateFormatted'           
       );
}

interviewDateFormatted is actually a call to the corresponding entity (Employee) method getInterviewDateFormatted which looks like this:

    public function getInterviewDateFormatted() {
    return ($this->interviewDate instanceof \DateTime) ? $this->interviewDate->format("Y-m-d") : "";
}

This way I can change date format or do other necessary changes to the fields I want to export.

Answer 5

Did you managed to make it work?

Date format is defined as parameter for new DoctrineORMQuerySourceIterator.php ( https://github.com/sonata-project/exporter/blob/master/lib/Exporter/Source/DoctrineORMQuerySourceIterator.php )

DoctrineORMQuerySourceIterator.php is created inside getDataSourceIterator function ( https://github.com/sonata-project/SonataDoctrineORMAdminBundle/blob/2705f193d6a441b9140fef0996ca392887130ec0/Model/ModelManager.php )

Inside of Admin.php there is function calling it:

   public function getDataSourceIterator()
   {
        $datagrid = $this->getDatagrid();
        $datagrid->buildPager();
        return $this->getModelManager()->getDataSourceIterator($datagrid, $this->getExportFields());
    }

If you write your own getDataSourceIterator() then you can change date format.
