I'm fairly new to Django REST framework and I've tried to write an API for my mobile application. I'm facing an issue where a PUT request works fine (updates data) apart from the fact it returns response 500 (Internal Server Error). Some guidance towards resolving this would be much appreciated.

views.py:

@csrf_exempt
def category_instance(request, pk):
 """
 Returns Category instance
 """
 try:
 cat = Category.objects.get(pk=pk)
 except Category.DoesNotExist:
 return HttpResponse("Error: category does not exist", status=404)

 if request.method == 'GET':
 serializer = CategorySerializer(cat, many=False)
 return JsonResponse(serializer.data, safe=False)

 elif request.method == 'PUT':
 serializer = CategorySerializer(cat, data=request.data)
 if serializer.is_valid():
 serializer.save()
 return JsonResponse(serializer.data, 200)
 return JsonResponse(serializer.errors, status=400)

 elif request.method == 'DELETE':
 cat.delete()
 return HttpResponse(status=204)

 else:
 return HttpResponse(status=400)

models.py:

class Category(models.Model):
 name = models.CharField(max_length=25, blank=False)

 class Meta:
 ordering = ('id',)

serializers.py:

class CategorySerializer(serializers.ModelSerializer):
 class Meta:
 model = Category
 fields = ('id', 'name')

urls.py:

urlpatterns = [
 path('category/<int:pk>/', views.category_instance)
]

I've tried to look for similar issues that other people may have had, but I was unable to construct a solution to my problem.

Traceback:

Internal Server Error: /category/1/

The issue was resolved by replacing the views with generic class-based views instead.
