== 2013 ==

* Ele         


        

Answer 1

A simple solution which have not been added here properly is this:

For year and month grouping, add the fields as Transient to your model:

...
/**
 * @var int
 * @transient
 */
protected $year;


/**
 * @var int
 * @transient
 */
protected $month;
/**
 * @return int
 */
public function getYear()
{
    if (!$this->year) {
        $this->year = $this->getDateTimeField()->format('Y');
    }
    return $this->year;
}

/**
 * @return int
 */
public function getMonth()
{
    if (!this->month) {
       $this->month = $this->getDateTimeField('n');
    }
    return $this->month;
}

Then in the template:

    
        ...
