Django QuerySet retuns empty queryset

Question

I have not been able to tell why this model query returns an empty queryset...

Here are my models:

class Marks(models.Model):
    klass = models.ForeignKey(Klass,on_delete=models.SET_NULL,null=True,blank=True)
    stream = models.ForeignKey(Stream,on_delete=models.SET_NULL,null=True,blank=True)
    mark = models.IntegerField()

class Klass(models.Model):
    name = models.CharField(max_length=20)

The view.

def ResultsView(request):
    query = request.GET.get('klass')
    if query:
        queryset = (Q(klass__name__icontains=query))
        the_student = Marks.objects.filter(queryset).distinct()
        all_results = {'the_student':the_student,'query':query}
    else:
        all_results =  {}
        
    return render(request,'exams.html',all_results )

The form template

    <form action="{% url 'search_marks' %}" method="GET">
        <div class="input-group">
        <input class="" style="flex:50%" type="text" name="klass">
         <button class="btn btn-primary" type="submit"></button>
        </div>
    </form>

The url

path('search_m',ResultsView,name='search_marks'),

I try getting the results here

{% for mark in the_student %}
    {{ mark }}
{% endfor %}

When I print the_student from the view it gives <QuerySet []>

When I try queryset = (Q(mark__icontains=query)) brings an answer for the mark. I only want a result for klass

Answer 1

I think you are using the whole queryset in your template.

Try

{% for mark in the_student %}
    {{ mark.klass }}
{% endfor %}

Answer 2

the_Student is your response key but you use the_student.

the_student != the_Student

you just change the

{% for mark in the_student %}
  {{ mark.klass }}
{% endfor %}

to

{% for mark in the_Student %}
  {{ mark.klass }}
{% endfor %}
