Django - Random - order_by('?')
When you make queryset in Django, argument "?" for order_by returns queryset in random order Model.objects.order_by('?') Documentation warns, that it may be slow. Also many articles tell not use this method for big database. I know question will sound dumb, but what is database limit size in order to user order_by efficiently? How many objects may I have in my database before order_by will get slower? Or this is all up to machine specs? -
Handle multiple parameters from URL in Django
In my app I am trying to make query on multiple parameters from the URL which is something like the following: /allot-graph/?sc=Infac%20India%20Pvt.ltd&type=FLC there are 2 parameters sc and type at times they can be empty as well I was handling the single parameter like the following: class AllotmentbyMonth(APIView): def get(self, request): q = 0 try: q = request.GET['sc'] except: pass if q == 0: print("q", q) dataset = Allotment.objects.all().annotate( month=TruncMonth('dispatch_date')).values( 'month').annotate(c=Sum('flows__alloted_quantity')).values('month', 'c') else: print("q") client = Client.objects.filter(client_name = q)[0].pk print("client", client) dataset = Allotment.objects.filter(sales_order__owner=client).annotate( month=TruncMonth('dispatch_date')).values( 'month').annotate(c=Sum('flows__alloted_quantity')).values('month', 'c') date = list(dataset) months = list() for i in date: months.append(i['month'].strftime("%B")) chart = {'chart': {'type': 'column', 'height': 400}, 'title': {'text': 'Allotments by Months'}, 'xAxis': {'categories': months}, 'yAxis': {"title": {"text": 'Count'}}, 'series': [{'name': 'Months', 'data': [{'name': row['month'], 'y': row["c"]} for row in dataset]}]} print("chart", chart) return Response(chart) I know it's not the ideal way but this was my workaround. How can I handle the filter type in this as writing too many if-else just doesn't seem right. The filter for type is this : .filter(flows__kit__kit_type = type) -

I have a Django project using the Rest Framework. In some view I'm trying tu execute some logic every time I call these views, but it works when I have an existing Database. If I have to do a migrate to create a new Database it gives me the error django.db.utils.OperationalError: no such table: bar_reference because I don't have any Database.

Can I dynamically place items in two-column template in Django?
The title might not be so clear, so let me elaborate more. I have a two-column template, and want to load some number of items in them. It would look like this: {{item1}} | {{item2}} {{item3}} | {{item4}} {{item5}} | {{item6}} {{item7}} | {{item8}} ...

Django: Dynamic Annotation and Filtering
I think this should not be complicated but i can't get it right. How can i conditionally count the number of brands in a specific category within a queryset? views.py def get_brands(request): all_brands = brand.objects.values('brand_name','brand_category').\ annotate(brand_proportion=Count('brand_name')/Count('brand_name', filter=Q(brand_category="brand_category"))#I'm stuck here return JsonResponse(list(all_brands), safe=False) I am not sure to filter the brand category and count the number of brands in that category. For example: brand_category 'A' might have: Brand 1,Brand 1 ,Brand 1,Brand 2,Brand 2 Here, the proportion of Brand 1 in category A would be 3/5 = 0.6 or 60% I can calculate the 3 using Count('brand_name') within the queryset, but how can i calculate the 5? brand_category 'B' might have: Brand 1,Brand 2,Brand 3,Brand 4,Brand 5 Here, the proportion of Brand 1 in category B would be 1/5 = 0.2 or 20% Please help.Thanks. -
