Hello guys. Can anybody help me? I got an error in Django This polls app tutorial. I did everything how it said I get ValueError at /polls/4/vote/. Field 'id' expected a number but got 'question_id'

Question_id might be a sing, check s it an int?

def vote(request, question_id): question = get_object_or_404(Question, pk='question_id') try: selected_choice = question.choice_set.get(pk=request.POST['choice']) except(KeyError, Choice.DoesNotExist): return render(request, 'polls/detail.html', {'question': question, 'error_message': "You didn't select a choice"}) else: selected_choice.votes += 1 selected_choice.save() return HttpResponseRedirect(reverse('polls:results', args=(question.id)))

objs.0.title in template should work

Is there an exception in Sqlite?because I have just tried here on MySQL and lazily executed with offset expression such below.

Item.objects.all()[2] creates sql below SELECT orderapi_item.id, orderapi_item.created_date, orderapi_item.last_updated_date, orderapi_item.transaction_id, orderapi_item.order_id, orderapi_item.item_type_id, orderapi_item.title, orderapi_item.description, orderapi_item.seller_user_id, orderapi_item.buyer_user_id, orderapi_item.listing_id, orderapi_item.creation_tsz, orderapi_item.price, orderapi_item.shipping_cost, orderapi_item.quantity, orderapi_item.product_data_base FROM orderapi_item LIMIT 1 OFFSET 2; args=()

I dont know whether sqlite supports OFFSET cursoring like above

Nope doesn't work this way.

What do you mean by does not work? Is it raising exception?

Yes, it's showing Django: TemplateSyntaxError: Could not parse the remainder......

Why dont you try to extract single row in view layer and by then send that with context?

Template layer is more error prune these kind of business logic overloading.

Extract all needed in view(like controllers on Java, .Net etc.) then send to presentation.

Yeah if nothing works. i will prefer this way.

I'm new to djnago rest framework. this is my model: https://pastebin.com/fneJpAfW I'm trying to create a serializer. but i want to filter the category field with request.user and i want do it from serializer. that means the user who is creating new item only can see the category he added not all the category. Sorry for my broken English

Yeah if nothing works. i will prefer this way.

That is a definite best practice in MVC or MTV structures. There are some occasions such as Model.NotFound exceptions for these kind of offsetting. How do you plan to manage that on Template layer? Will you search a way to exception handling on the template?

need help payment functionality in django secure or not 😅

Hi whats the best video course until you are see for learning django?

need help payment functionality in django secure or not 😅

If you implement your payment functionality your own, it is a very detailed process, otherwise 3rd party payment providers will take the responsibility of security.

Every modern framework is able to fulfill all concerns about integrating payment functionality.

it's secure if you know what you do 😊
