n:if activerow in latte template

pistols

hello there,

I have a question about the n:if macro.

my model does something like this:

<?php
return $this->database->table(self::TABLE_NAME)->where(self::COLUMN_ROLE, $type);
?>

and my presenter puts that activerow directly into my template.

My problem is with the n:if makro

if I do this:

<div n:if="values">
 Yap!, you have some nicely crafted values there!
</div>

evaluates always true… even when i have no returned data from my model.

I dumped the active row, and indeed it is a live object (TRUE). but with no data…

could you point me how to nicely hide the div if my result set is empty?

thanks

ActiveRow cannot be “empty”, only Selection can. On Selection you can do something like this:

<div n:if="count($values)">
...
</div>

I know 2 diferent ways.

In your method make decision if database returned any data:

public function findRole()
{
	return $this->myReturn($this->database->table(self::TABLE_NAME)->where(self::COLUMN_ROLE, $type));
}

protected function myReturn($return)
{
	if (count($return) == 0) {
		$return = false;
	}
	return $return;
}

It will work with your usage if.

Didn't test if some data were returned and put into n:if count of rows

<div n:if="count(values) > 0"> // or you can use values->count() > 0
 Yap!, you have some nicely crafted values there!
</div>

Great!, I used the values->count() and it works like a charm

thanks a lot.
