Django Rest Framework CRUD
I´m building an API with Django Rest Framework, and I’m wondering if it's enough to use only the ModelViewSet class to implement the CRUD. My worries is that it’s not enough for the frontend to consume and use the create, read, update and delete functionalities. -

Dynamically Loading Data Into Django Modal
I've been trying to implement a way to dynamically load information into a modal in order to do a quick preview for my ecommerce site. Any help would be appreciated, I'm not sure which direction I should head in. I tried to play with Javascript and creating an onclick function to refresh the div, but I have had no success so far.

How do I filter querysets by a field chosen from template form in Django?
I'm learning Django. I have a listview and detailview for a queryset, all working properly. In the listview, I want the user to be able to search the model database choosing to look for given string in one, many, or all the model's fields. Since the filter() method gets field name as .filter(name__icontains='string') I don't know how to pass this name parameter from the form checkboxes. -
What is causing my django authentication backed to be so slow?
I have a custom authentication backend. def authenticate(self, request): start = time.time() auth_header = request.META.get("HTTP_AUTHORIZATION") if not auth_header: raise NoAuthToken("No auth token provided") id_token = auth_header.split(" ").pop() try: decoded_token = decode_verify_firebase(id_token) except Exception: raise InvalidAuthToken("Invalid auth token") if not id_token or not decoded_token: return None try: uid = decoded_token.get("user_id") email = decoded_token.get("email") except Exception: raise FirebaseError() q_start = time.time() user, created = User.objects.get_or_create(username=uid, email=email, firebase_user=True) logger.info(f'getting the user --- {time.time() - q_start}') logger.info(f'Total auth time --- {time.time() - start}') return user, None Note: I am custom decoding the firebase token, there is no outgoing request here. I put some time stamps in this function for profiling: getting the user --- 0.5818960666656494(s) Total auth time --- 0.5826520919799805(s) You can see that user query is taking the bulk of the time. This is also causing my authenticated endpoints to perform very poorly. However, when I log the queries it reports the query being very quick. Execution time: 0.089754s [Database: default] Any ideas what I could do to fix or improve this? -

Trying to pass traffic through NGINX container to Django with Kubernetes
I'm stuck on something that I feel is rather simple for someone who may know kubernetes. I a django app I'm trying to deploy to production. Part of that will be adding an SSL cert so I believe to do that I need something like an nginx container for public traffic to hit first. I have this working in docker-compose but our production environment is a kubernetes cluster. I was able to get the kubernetes file to spin up the containers but traffic just goes straight to the django app. How would I configure this to pass traffic through nginx instead? apiVersion: apps/v1 kind: Deployment metadata: name: networkapp-deploy labels: name: networkapp spec: replicas: 1 selector: matchLabels: name: networkapp_pod template: metadata: labels: name: networkapp_pod spec: containers: - name: nginx image: nginx:alpine ports: - containerPort: 8000 - name: redis image: redis:alpine ports: - containerPort: 6379 - name: webapp image: localhost:5000/newweb/webapp:latest ports: - containerPort: 8001 --- kind: Service apiVersion: v1 metadata: name: networkapp-svc spec: selector: name: networkapp_pod ports: - protocol: TCP port: 80 targetPort: 8000 type: LoadBalancer Here is the docker compose file which seems to work if I run it locally off of that, I just need this to work in kubernetes … -

Collect payments and pay out
I'm developing an iOS application (with a Django backend) with an internal currency system. Users will be able to purchase coins and redeem them for real money. I will not use the in-app purchase but a custom payment system (I'm allowed to do this and the question is not about Apple's guidelines). I'm searching for an API that allows me to collect payment and pay out users as fast as possible globally and without daily/weekly/monthly limitations. My problem is that I don't want to accumulate the earnings on a bank account/credit card since they have limitations in the number of transactions, so performing mass pay outs is not possible. Is there a way to receive payments with Stripe/PayPal/Braintree without transferring funds to a bank account and then pay users quickly with previously accumulated money? If it is possible would you direct me to related resources/documentation? -
Referenced Url works with static number but not with variable

Django getting session 500 error on specific line
I'm trying to run the code here: https://github.com/TwilioDevEd/automated-survey-django. The problem I'm stuck on is in the below function, the first time a text is send, there is no session and request.session.get('answering_question_id') is false/null. The second text sent from the same number (where I can see there is a new row in the django_session table), returns a 500 error on this line request.session.get('answering_question_id'). I see a 500 error is a server error, but I'm stuck on what that could mean for this. I thought the result should just be false/null if 'answering_question_id' isn't available. Any thoughts? @require_http_methods(["GET", "POST"]) def redirects_twilio_request_to_proper_endpoint(request): print("HELLOOOO!") answering_question = request.session.get('answering_question_id') print("YEPPERS") if not answering_question: print('1') first_survey = Survey.objects.first() redirect_url = reverse('survey', kwargs={'survey_id': first_survey.id}) else: print('2') question = Question.objects.get(id=answering_question) redirect_url = reverse('save_response', kwargs={'survey_id': question.survey.id, 'question_id': question.id}) return HttpResponseRedirect(redirect_url) -
Django MultiTenant saas registeration
I have been coding my project using a single DB and tenant_ids for each entry I wanted to switch to django-tenant and have schema based app. My question is about the initial registration. Registration should be a shared app but do i need to create a tenant for "public" regardless so that everyone becomes that tenant when they are registering? And do you add this public tenant with a script onetime when you set up the project so that you have a "public" tenant. Creating a tenant for public feels a bit odd. Or what would be the registration sequence be like( Ideally registration should create the tenants) Ideally my flow should be : you register a tenant with an email so that when tenant registers it sends an email and when you activate that mail you create your first user (admin user) for that tenant. -
