Check If All Objects Belong To A List Django

Template: {% for level in levels %} {% if level.todo_set.all in tasks %}

<

Solution 1:

You are probably best to handle this inside your view.

for level in levels_list:
    if Todo.objects.filter(level=level).count() == Task.objects.filter(student=student, level=level).count():
        return (level completion code)

Solution 2:

levellist = []
for level in levels:
    if (
        ToDo.objects.filter(level=level).count()
        == Task.objects.filter(student=student, level=level).count()
    ):
        levellist.append(level.number)
    perc = (len(levellist) / len(levels)) * 100

In Template:

{% for level in levels %}
    {% if level.number in levellist %}
    <li>
        <a href="javascript:;"><img src="{{ level.badge.url }}" 
        alt=""/></a>
    </li>
    {% else %}
    <li>
        <a href="javascript:;"><img src="{{ level.locked_badge.url }}" 
        alt=""/></a>
    </li>
    {% endif %}
{% endfor %}

Found a fix!
