Django sum, return total

I have to filter it by categories.
How I do it?
I have to use a query like SELECT total, category from my_table where category = 1?
models.py
class Big(models.Model):
size = models.CharField(max_length=100)
order_price = models.DecimalField(max_digits=5, decimal_places=2)
total = models.DecimalField(max_digits=5, decimal_places=2)
def __str__(self):
return str(self.size)
class Products(models.Model):
products_id = models.IntegerField(primary_key=True)
product_name = models.CharField(max_length=100)
sizes = models.ManyToManyField(Big)
views.py
def product(request):
query = Products.objects.all()
query_filter = Products.objects.filter(sizes__category = '1')
query_product = query_filter.order_by('-products_id')

return render(request, "index.html", { ac619d1d87
