[FIXED] Python, Django: 'Videos' object is not iterable, for video in chunk

Issue

How to fix that error?

In template C:\Users\webst\webstudioamerica\webstudio\templates\index.html, error at line 441 Python: 'Videos' object is not iterable This code is not working:

439             {% for chunk in videos|slice:":3" %}
440             <div class="row">
441                 {% for video in chunk %}
442                 <div class="col-xs-12 col-lg-4">
443                     <div class="video-container">
444                         <iframe class="video" src="{{ video.video_id }}" allowfullscreen></iframe>
445                     </div>
446                 </div>
447                 {% endfor %}
448             </div>
449             {% endfor %}

This one is working:

{% for video in videos %}
            <li>{{ video.video_id }}</li>
{% endfor %}

views.py is the same:

from django.shortcuts import render
from .models import Videos

def index(request):
    videos = Videos.objects.all()  
    return render(request, 'index.html', {'videos': videos})

Solution

Your code here actually confirms that each entry in the QuerySet is not iterable:

{% for video in videos %}
    <li>{{ video.video_id }}</li>
{% endfor %}

So when you slice the QuerySet here, each chunk is now just one entry from the sliced QuerySet just like video is as shown in the above.

Hence chunk in the below code represents just one entry gotten from each iteration over the QuerySet Videos.objects.all().

{% for chunk in videos|slice:":3" %}

chunk is not iterable. That is why this line throws the errors you got:

{% for video in chunk %}
