Why Django couldn't find an object with given slug?
Django tells that the object with given slug could not be found (i.e. 404 code). Though queryset returned isn't empty class PollDetailView(RetrieveAPIView): serializer_class = PollSerializer def get_queryset(self): slug = self.kwargs['pk'] print(Poll.objects.filter(slug=slug)) # Prints '<QuerySet [<Poll: ddd>]>' reaching '/api/poll/ddd/' url return Poll.objects.filter(slug=slug) # 404 Not Found -

How to incorporate one API endpoint with another?
I am new to Django Rest and using API's. So, I have an existing project where I am getting estimated price from a method price_estimation_based_on_region. I want to use the result_data object from here to another method, where I am sending and saving the new inquiry in a method name save_new_inquiry. The price is coming as a response from an endpoint which I need to associate in the save_new_inquiry method. How to do this? Here are the methods: def save_new_inquiry(self, data: dict): try: LOGGER.info('GENERATE NEW INQUIRY=======================') time_services = TimeServices() main_data = data['data'] region, address_details = self.find_region(main_data) main_data['region_id'] = region.id if region else None inquiry_serializer = InquirySerializer(data=main_data) if inquiry_serializer.is_valid(): saved_data = inquiry_serializer.save() saved_data.from_address_zip_code = address_details['postal_code'] saved_data.save() send_email = EmailServices() data = self.formatting_data_for_api_call(main_data) if region: response = API(domain=region.region_company_ids.first().db_name, method_name='query-form', data=json.dumps(data), token=FB_CONFIG['apiKey']).execute(TYPE.POST) LOGGER.info(response.text) if response.status_code == 200: response_data =json.loads(response.text) saved_data.gen_qid = response_data.get('gen_qid','') saved_data.order_id = response_data.get('id','') saved_data.link_hits = region.region_company_ids.first().db_name saved_data.is_associated_company = True saved_data.save() send_email.email_send_to(email=[data['customer_email']], subject="Takk for henvendelsen din!", template='email_inquiry.html', context={}, source='BusGroup <no-reply@busgroup.no>') def price_estimation_based_on_region(self, data: dict): try: region,address_details =self.find_region(data) time_services = TimeServices() main_submission = { "passenger": data.get('passenger',0), "order_type": data.get('order_type','Single'), "bus_availability": data.get('availability','False'), "departure_datetime": time_services.convertUserTimeToUTCwithFormat( time=data.get('departure_datetime', ''), input_format='%d.%m.%Y %H:%M', output_format='%Y-%m-%d %H:%M:%S', tz_time='Europe/Oslo'), "return_datetime": time_services.convertUserTimeToUTCwithFormat( time=data.get('return_datetime', ''), input_format='%d.%m.%Y %H:%M', output_format='%Y-%m-%d %H:%M:%S', tz_time='Europe/Oslo'), "from_address": data.get('from_address',''), "from_address_latlng": data.get('from_address_latlng',''), "to_address": … -

ManyToManyField Self object lis comes up as empty in the Admin panel of Django
I've got a Model object of Document that has a number of fields that link to itself. However, when creating a new object from the admin page, or editing an existing one, the list of linked Documents come up as empty. Other ManyToManyFields that are in the same object seem to be fine, and list the right content. I tried changing the related_name filter and play around with symmetrical and even changed self to Document,it still comes up as an empty list (I have other Document objects already created, so the object list is not empty) Note: I can tell they still link to Document as when I click the little plus button to add a document inside the document (recursive add), the pop up I get is for another Document with the right fields.

how to configure autocomplete_light in django 2.2?
I tried to configure autocomplete_light for django2.2 but i'm getting some errors its because for django version i guess.

How to add URL component to current URL via a HTML button? (Django 2.1)
I have a HTML button that is supposed to sort the search results by alphabetical order. Button HTML code: <a href="?a-z=True" type="button" class="btn btn-outline-{% if 'a-z' in request.GET %}success{% else %}secondary{% endif %}">A-Z</a> views.py: def query_search(request): articles = cross_currents.objects.all() search_term = '' if 'keyword' in request.GET: search_term = request.GET['keyword'] articles = articles.annotate(similarity=Greatest(TrigramSimilarity('Title', search_term), TrigramSimilarity('Content', search_term))).filter(similarity__gte=0.03).order_by('-similarity') if request.GET.get('a-z') == 'True': articles = articles.order_by('Title') Currently, the URL contains the keywords searched by the user. For example, if the user searches for "cheese," the URL will be search/?keyword=cheese. When I click the sorting button, the URL becomes search/?a-z=True and loses the keyword, which means that the sorting mechanism isn't sorting the search results based on the keyword. I think I need the URL to contain both the keyword and ?a-z=True for the sorting mechanism to work on the search results. How can I make that happen?
