Silverstripe Version: 4.2.2

Question:
Hello All!
I 've search in API 4.0, but can’t find an answer… :frowning_face:
i have a dB date field type in my SS_silverstripe data base using MariaDB.
i have un array and push the ‘mDates’=>$row[‘Date’]. That’s right and OK.
So, in the template, if i use $mDates, i have the good return, i see the good Date.

But, there is a but…
when i try to use in the template format expression like this (new (CLDR format), $mDates.Format(‘dd.MM.y’), i have un empty return… Please Doctor, where’s my problem?

Thank’s a lot for your return :wink:

...
//print_r($type);
//
	$list1->push(
		new ArrayData(array(
			'mDates'=>$row['Date'],
			'mAbstract'=>$row['Abstract'],
			'mTitle'=>$name,
			)
		)
	);
...
...
<%-- ***SAMPLE DATE FORMAT*** --%>
<div class="fatDate">
       <span class="dates">$mDates.Format('dd.MM.y')</span>
	<span class="dayOfMonth">$mDates.Format('dd)</span>
	<span class="month">$mDates.Format('MM')</span>
	<span class="year">$mDates.Format('y')</span>
</div>
...

Most likely, the reason you’re not getting anything is that in the course of the process, you’re pushing a string into the arraydata. In order to be able to use the formatting in a template you need a date object in there.

Can you expand on your code a little more? Is there a reason you’re manually creating the ArrayData? How are you getting the data from the database?

hey DorsetDigital! thank’s to you for you’r interest!
I understant what’s you said, and thinking like you. And i trying to test with the SetDateFormat.
So In my error.log:
[2018-12-24 11:47:38] error-log.ERROR: Uncaught Exception Error: “Call to a member function setDateFormat() on string” at /var/www/silverstripe/app/src/Page.php line 116 {“exception”:"[object] (Error(code: 0): Call to a member function setDateFormat() on string at /var/www/silverstripe/app/src/Page.php:116)"}

So i found this solution, but it’s not realy sexy…

in my dB this is the table ‘MediaPage’:
|Colonne|Type|
|ID|int(11)
|ExternalLink|varchar(255)
|Abstract|mediumtext
|Date|date
|MediaTypeID|int(11)

//News-Tag-Jeunes
public function RecentJeunes()
		{
		$list1 = ArrayList::create();
		//
		$sqlQuery = new SQLSelect();
		$sqlQuery->setFrom('MediaPage');
		$sqlQuery->selectField('*');
 	       $sqlQuery->addInnerJoin('MediaPage_Categories','"MediaPage_Categories"."MediaPageID" = "MediaPage"."ID"');
		$sqlQuery->addWhere('"MediaPage_Categories"."MediaTagID" = 1');
		$sqlQuery->setOrderBy('Date', 'DESC');
		// $sqlQuery->setGroupBy(...);
		// $sqlQuery->setHaving(...);
		$sqlQuery->setLimit(3);
		//$sqlQuery->setDistinct(true);
		//
		// Execute and return a Query object
		$results = $sqlQuery->execute();
		//
		// Iterate over results
		//print_r($results);
		//
		foreach($results as $row) {
			//
			$type = SiteTree::get()->byID($row['MediaPageID']);
			if ($type) { 
				$name = $type->title;
			} else {
				$name="";
			}
			//
			$list1->push(
				new ArrayData(array(
					//'mDates'=>$row['Date'],
					'mDatesD'=>date('d',strtotime($row['Date'])),
					'mDatesM'=>date('m',strtotime($row['Date'])),
					'mDatesY'=>date('Y',strtotime($row['Date'])),
					'mAbstract'=>$row['Abstract'],
					'mTitle'=>$name,
				)
			)
		);
		//
		//print_r($list1);
		return $list1;
}
<article>
		<span class="title">Jeunes</span>
		<% loop $RecentJeunes %>
				<%-- p class="infos">$Title - $Date - $Abstract.LimitWordCount(10)</p --%>
				<div class="event">
					<div class="fatDate">
						<span class="dayOfMonth">$mDatesD</span>
						<span class="month">$mDatesM</span>
						<span class="year">$mDatesY</span>
						<p>&nbsp;</p>
					</div>
					<div class="fatText">
						<h3>$mTitle.UpperCase</h3>
						$mAbstract.LimitWordCount(10)
						<p>&nbsp;</p>
					</div>
				<a href="$InternalLink" class="readMore"> >> Read More...</a>
				</div>
		<% end_loop %>
</article>

if you can tel me more, i realy appreciate!
Thanks.

Hi,

Is there a reason you’re not using the ORM for these queries? Having queries nested inside a foreach loop has the potential for some serious performance issues.

In theory you should be able to replace all that code with a relatively simple one-liner (assuming you have the relation set up between MediaPage and MediaPage_Categories) :

public function getRecentJeunes() {
  return  MediaPage::get()->filter(['MediaPage_Categories.MediaTagID' => 1])->Limit(3);
}

Then in your template, you can use the format() methods, eg: $Date.Format('MM')
