Can Twig count the array lenght with a filter parameter

I have an Account object that contains an one-to-many relation with the newsbrief members. In Twig a want to show the quantity of members. I know that I can show the quantity with the following code:

{{ account.mailList|length }}

Only the mailList contains also inactive members. With these members their field active is false. Is there a way to filter them out? Is this way of working slowing down the application?

You can use for loop in twig:

{% set activeMailCount = 0 %}
{% for mail in account.mailList if account.mailList.active %}
    {% set activeMailCount = activeMailCount + 1 %}
{% endfor %}

You could create a method on the account entity that returns active members

// src/AppBundle/Entity/Account.php
public function getActive()
{
    $count = 0;

    foreach($this->getMailList() as item) {
        if (item->isActive()) { // Assuming the newsbrief members are entities
            $count++            // with an $active property & isser().
        }
    }

    return $count;
}

and call that from Twig:

{{ account.getActive() }} # or {{ account.active }}
