How to add extra fields outside the list of items in modelView ? (like count for pagination)
I'm looking for the best way to add additional fields to the get list return of a ModelView. I have the following model: class Sale(models.Model): total = models.FloatField(_("Total")) name = models.CharField(_("Name")) [...] When I do a get list on this model, I get the following json: { "count": 0, "next": "http://example.com", "previous": "http://example.com", "results": [ { "id": 0, "name": "example", "total": 0, [...] } ] } I would like to add 2 fields min_total and max_total to the result (at the same level as "count"). Example: { "count": 0, "next": "http://example.com", "previous": "http://example.com", "min_total": 0, "max_total": 100, "results": [ { "id": 0, "name": "example", "total": 100, [...] } ] } My View: class SaleViewSet(viewsets.ReadOnlyModelViewSet): """ A simple ViewSet for listing or retrieving sales. """ permission_classes = [permissions.IsAuthenticated] filter_backends = [DjangoFilterBackend, filters.OrderingFilter] filter_fields = ['client', 'machine', 'date_time', 'total'] ordering_fields = '__all__' def get_serializer_class(self): if hasattr(self, 'action') and self.action == 'list': return SaleListSerializer if hasattr(self, 'action') and self.action == 'retrieve': return SaleRetrieveSerializer return SaleSerializer def get_queryset(self): queryset = Sale.objects.all().select_related('client') user = self.request.user if user.is_staff: cache_key = 'list_sale_sales' else: queryset = queryset.filter(client=user.profil.client) cache_key = f'list_sale_sales_client_{user.profil.client.pk}' return cache.get_or_set(cache_key, queryset, 60) To get these 2 values I just have to make these 2 requests: Sale.objects.all().aggregate(min=Min("total")) … -

While proceeding to pay , the invalid amount popup appears in razorpay
Below I've attached an image which occurs when I click on Proceed To Pay. When the order is being created, it successfully creates razorpay_order_id and also prints the order_amount, but it doesn't pushes that amount to the gateway. If no razorpay_order_id has been newly created then it will create a razorpay_order_id and print the values of order(i.e. username), order_id, x and order_amount, else it only prints the value of order and execute the else block. But after executing any of the blocks, the order_amount is not been pushed to the razorpay payment process. Below are the python code for the Razorpay Integration: Views.py- @login_required def payment(request): add = Address.objects.filter(default=True) order = Order.objects.filter(user=request.user).first() print(order) client = razorpay.Client(auth=("ABC", "XYZ")) # Creating a Razorpay order if no order_id has been created if order.razorpay_order_id is None: order_id = order.order_id print(order_id) #prints the order_id x = order.get_total() print(x) #prints the total amount order_amount = int(x * 100) print(order_amount) #prints the total amount in paise order_currency = 'INR' order_receipt = 'Rcpt' notes = {'Shipping address': 'LMN, OPQ'} # OPTIONAL # data = {"amount": order_amount, "currency": order_currency, "receipt": order_receipt, "payment_capture": '1', "notes": notes} # razorpay_order = client.order.create(data) razorpay_order = client.order.create(amount=order_amount, currency=order_currency, receipt=order_receipt, payment_capture=1, notes=notes) # Razorpay order … -

python bcp insert without knowing order of columns
I'm using Django and bcp to insert huge amounts of data into my database. As of now, I have a dataframe which I convert to a CSV using to_csv() which my BCP command then reads and uploads to DB. However, for it to upload correctly, I have to have the file in the exact order as columns in DB and as of now I'm doing it manually like this: data = data[['id', 'data_date', 'data', 'created_at', 'modified_at', 'signal_id']] I tried using the following command to get the order of columns from the table as I learned from this answer but it didn't seem to return anything. Process just got stuck bcp_string_get_col_names = "bcp \"DECLARE @colnames VARCHAR(max);SELECT @colnames = COALESCE(@colnames + ',', '') + column_name from {}.INFORMATION_SCHEMA.COLUMNS where TABLE_NAME='{}'; select @colnames;\" queryout HeadersOnly.csv -S {} -U {} -P {}".format(database, table, host, user, password) status = subprocess.run(bcp_string_get_col_names, stdout=subprocess.PIPE) The command which uploads my data to database looks like this: bcp_string_upload = 'bcp {} in {} -S {} -d {} -U {} -P {} -t "{}" -c -F {} -b 20000'.format(table, file, host, database, user, password, sep, row_start) status = subprocess.run(bcp_string_upload, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) I would really appreciate if either you could tell me how … -
Add twilio webhooks dynamically from a multi-tenant django application with subdomains for twiml
I have tested twilio's twiML api for sending and receiving text messages in application and it worked well. However I had to ngrok the specific test sub-domain I was testing from as the receiving Webhook on Twilio panel. In real use case, because it's a multi-tenant application, this needs to be dynamic, not just a single Webhook endpoint e.g www.first.mysite.com/sms-chat-bot, www.second.mysite.com/sms-chat-bot etc etc. The question is, how do I achieve this either via twiml or twilio rest api (couldn't find a single documentation on this, as everything seems to favour Webhooks). -

How to add event for checked row
I'm using django and it's printing a table. Currently, using the latest jquery script, clicking the Transfer Selected Rows button moves the selected rows to the second table. But I'm managing a server and I want the second table to be saved and visible to users. Should I create another class model to store the second table? Alternatively, when moving to the second table for the checked row, I would like to change the select column to name column and add the user name currently logged in in bulk. Another method I thought of is to apply a different color to each checked row and save it to the server. That is, I have 2 teachers and I want to assign them to students.

Upload file from Django app to IBM Cloud Object Storage
I'm trying to connect a django app to IBM COS and having trouble. I'm capturing user video and want to save the file to IBM COS and the user info to Postgres also hosted on IBM. I'm able to connect from both the terminal and my app to IBM COS and move files around, but am having trouble getting the default storage configured properly. I'm using django-storages, trying to adapt the AWS configurations for IBM but I must be missing something. This code will save the file to IBM COS, but makes no entries in the DB. The problem may be in the configuration? Also, I am not able to manually upload a file form the django admin panel - I get a similar traceback. Thanks in advance for any help. settings.py # IBM STORAGE CONFIG IBM_API_KEY_ID = 'IBM_API_KEY_ID' IAM_SERVICE_ID = 'IAM_SERVICE_ID' ENDPOINT = 'https://s3.us-east.cloud-object-storage.appdomain.cloud' IBM_AUTH_ENDPOINT = 'https://iam.bluemix.net/oidc/token' SERVICE_INSTANCE_ID = 'SERVICE_INSTANCE_ID' IBM_STORAGE_BUCKET_NAME = 'cloud-object-storage-3u-cos-standard-77w' AWS_S3_FILE_OVERWRITE = False AWS_DEFAULT_ACL = None DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' models.py class Video(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) created = models.DateTimeField(auto_now_add=True) videofilename=models.CharField(max_length=500) videofile=models.FileField(upload_to="video/", null=True, verbose_name="") def __str__(self): return str(self.videofile) views.py class upload_to_ibm_auto(LoginRequiredMixin, CreateView): model = Video context_object_name = 'Videos' form_class = VideoForm template_name = 'app_video/upload_to_ibm_auto.html' success_url …
