the user in session stores the username.
And this is my "home.html" file:
{% extends "base.html" %}
{% block title %} Home {% endblock %}
{% block content %}
<div class="accordion accordion-flush" id="accordionFlushExample">
{% for x in range(0, count) %}
<div class="accordion-item">
<h2 class="accordion-header" id="flush-heading{{x}}">
<button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#flush-collapse{{x}}" aria-expanded="false" aria-controls="flush-collapseOne">
<strong>{{topics[x]}}</strong>
</button>
</h2>
<div id="flush-collapse{{x}}" class="accordion-collapse collapse" aria-labelledby="flush-headingOne" data-bs-parent="#accordionFlushExample">
<div class="accordion-body">Gemeinsame Kursteilnehmer:
</div>
{% endfor %}
</div>
<p><h1>{{topics}}</h1></p>
{% endblock %}
Any help on solving this error is really appreciated!
