Change a boolean value after a click on a button in Django - ajax

Question

I need some help regarding button clicks and boolean value changes.
My model:
class Topic(models.Model):
subject = models.CharField(max_length=255)
category = models.CharField(max_length=255)
last_updated = models.DateTimeField(auto_now_add=True)
starter = models.ForeignKey(User, on_delete=models.CASCADE, related_name='topics')
slug = models.SlugField(unique=True)
isReported = models.BooleanField(default=False)
startPrice = models.IntegerField(validators=[RegexValidator(r'^\d{1,10}$')])
I want to change the state of the field "isReported" from the default value "False" to "True" after a click on a button:
<button type="submit" class="btn btn-primary btn-block">Report</button>
I already googled and found something like this on SO (How do I change a value in django on button click in HTML?) but I am lacking knowledge of the concept presented in this thread. Unfortunately this was the only helpful information I could find.
How can I change the boolean value in my database after a single button click? It is not neccessary to change the value back on this button.
I somehome tried to adapt the code of the link:
views.py:
def ajax_change_status(request):
isReported = request.GET.get('isReported', False)
pk = request.GET.get('pk', False)
# first you get your Job model
job = Topic.objects.get(pk=pk)
try:
job.isReported = isReported
job.save()
return JsonResponse({"success": True})
except Exception as e:
return JsonResponse({"success": False})
return JsonResponse(data)
xxx.html:
<form method="post" novalidate>
{% csrf_token %}
<button type="submit" class="btn btn-danger btn-sm" id="change" role="button">Report</button>
</form>
<script>
$("#change").on('click', function () {
var pk = '{{ topic.pk }}'
var isReported = 'True'
$.ajax({
url: '/ajax/change_status/',
data: {
'isReported': isReported
'pk': pk
},
dataType: 'json',
success: function (data) {
if (data.success) {
alert("ajax call success.");
// here you update the HTML to change the active to innactive
}else{
alert("ajax call not success.");
}
}
});
});
I am trying to understand the concept, but (obv.) it is not working.
