Not usable in Podlove

[nie-froehlich]

as of version 4.1.15, a change breaks this template. Here's the changelog for the release in question:

security: disable unsafe Twig Template filters „filter“, „map“ and „reduce“

Unfortunately, the template makes heavy use of filter and therefore doesn't work with that version of Podlove any longer.

@nie-froehlich Thank you for pointing out. I think we can work around the filter method. I'll try to fix it if I find some spar time.

With a little help from an AI friend I came up with this solution. This is for statistik.twig:

{% set sum = 0 %}
{% set count = 0 %}
{% for episode in podcast.episodes %}
   {% set sum = sum + episode.duration.totalMilliseconds %} 
   {% set count = count + 1 %}
{% endfor %}

{% set validEpisodes = [] %}

{% for episode in podcast.episodes %}
    {% if episode.total_downloads > 0 %}
        {% set validEpisodes = validEpisodes | merge([episode]) %}
    {% endif %}
{% endfor %}

<p>Bisher haben wir <b>{{ count }} Folgen</b> veröffentlicht die <b>im Durchschnitt {{ (sum / count / 1000 / 60)|round(0, 'floor') }} Minuten</b> lang sind. In Summe haben wir schon <b>{{ (sum / 1000 / 60)|round(0, 'floor') }} Minuten gepodcasted</b>, das sind <b>{{ (sum / 1000 / 60 / 60)|round(2) }} Stunden</b>.</p>

<h2>Downloads</h2>
{% set latest = podcast.episodes[0] %}
<p>Unsere aktuelle Folge (<a href="{{ latest.url }}"><b>{{ latest.title }}</b></a>) hat bisher <b>{{ latest.total_downloads }} Downloads</b>. {% if not latest.meta('_podlove_downloads_2d') is empty %} In den ersten 48 Stunden waren es <b>{{  latest.meta('_podlove_downloads_2d') }} Abrufe</b>.{% endif %}</p>
