Why is this (Django) 'filter' function not working?

Question

I need help to figure out why the filtering doesn't work. It worked until I decided to add pagination using Django official docs and code comes from here.) I tested the query results in Django shell (following the steps in the docs ) and tweaked the code. The pagination itself displays, but instead of 5 items on each page (as specified in the line paginator = Paginator(gem_list, 5), all the items are displayed--and the same on every page. So I'm baffled as to whether the problem is with the filter part, or with the template.

#views.py

def gem_list(request):
   # gem_list = Rhyme.objects.filter(is_gem=True)
    rhyme_list = Rhyme.objects.all()
    objects= list(rhyme_list)     #converting the queryset to a list
    gem_list = objects.filter(is_gem=True)
    paginator = Paginator(gem_list, 5)
    page = request.GET.get('page', 1) 
    page_number = request.GET.get('page')
    page_obj = paginator.get_page(page_number)
    page_range = paginator.get_elided_page_range(number=page) 
    
    try:
        page_obj = paginator.get_page(page_number)
    except PageNotAnInteger:
        page_obj = paginator.page(1)
    except EmptyPage:
        page_obj = paginator.page(paginator.num_pages)

    context = {
        'page_obj': page_obj,
        'gem_list' : gem_list,
        'paginator' : paginator,
        'page' : page,    
        }
    return render(request, 'rhymes/gem_list.html', context)

#template:
<div class="container">

{% for gem in gem_list %}

    <p class="rhyme_list"> <a href="{{ gem.get_absolute_url }}">{{gem}}</a></p>

{% endfor %}


<ul class="pagination justify-content-center flex-wrap mt-3 mb-4">
  {% if page_obj.has_previous %}
  <li class="page-item"><a class="page-link" href="?page=1">First</a></li>
      <li class="page-item"><a class="page-link" href="?page={{ page_obj.previous_page_number }}">Previous</a></li>
  {% else %}
      <li class="disabled page-item"><span class="page-link">Previous</span></li>
  {% endif %}
  {% for i in page_range|default_if_none:page_obj.paginator.get_elided_page_range %}
      {% if page_obj.number == i %}
          <li class="active page-item"><span class="page-link">{{ i }} <span class="sr-only">(current)</span></span>
          </li>
      {% else %}
          {% if i == page_obj.paginator.ELLIPSIS %}
              <li class="page-item"><span class="page-link">{{ i }}</span></li>
          {% else %}
              <li class="page-item"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li>
          {% endif %}
      {% endif %}
  {% endfor %}
  {% if page_obj.has_next %}
      <li class="page-item"><a class="page-link" href="?page={{ page_obj.next_page_number }}">Next</a></li>
      <li class="page-item"><a class="page-link" href="?page={{ page_obj.paginator.num_pages }}">Last</a></li> 
  {% else %}
      <li class="disabled page-item"><span class="page-link">&raquo;</span></li>
  {% endif %}
</ul>

You have to display the page objects (page_obj) instead of the full gem_list:

{% for gem in page_obj %}

    <p class="rhyme_list"> <a href="{{ gem.get_absolute_url }}">{{gem}}</a></p>

{% endfor %}
