Error Assigning Foreign Key in Django CreateView, can't get an instance
Issue: Cannot Assign "38" to "Pusinex2.seccion" - Must Be a "Seccion" Instance Models: The models Seccion and Pusinex2 are related in a ForeignKey manner.

Swagger not working correctly through Nginx
We are developing web application in our class, and one of the tasks is to configure swagger for documentation. I did it, and it works perfectly. However, next we had to configure nginx and now when sending request with swagger through nginx it isn't requesting correct url (it requests http://127.0.0.1/api/v1/albums/ instead of http://127.0.0.1:82/api/v1/albums/) This is my config for swagger location /api/v1/swagger/ { proxy_pass http://127.0.0.1:8000/swagger/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } (I am developing web app with django, for swagger i'm using drf_yasg) I tried adding 'API_URL': 'http://127.0.0.1:82/api/v1/', in my SWAGGER SETTINGS in Django but it didn't fix anything -

Reassign all Guardian User Object Permissions from one Django User to another Django User
I have a Django system that users Guardian's User Object Permissions. I want to write a function that finds all permissions across all content types associated with an "old" user and assign them to a "new" user. I cannot query UserObjectPermission directly because our system uses direct foreign key tables for performance reasons. Here is an example of what I want from django.contrib.auth.models import User from guardian.shortcuts import get_objects_for_user, assign_perm def update_permissions_for_user(old_user, new_user): # Retrieve all USER permission objects for the old user # this throws exception because it requires a perms param that I do not want to provide. I want all objects across all models old_user_permissions = get_objects_for_user(old_user, use_groups=False, any_perm=False, with_superuser=False, accept_global_perms=False) # Iterate through each permission object and update it to point to the new user for permission in old_user_permissions: assign_perm(permission.codename, new_user, permission) remove_perm(permission.codename, old_user, permission) # Example usage: old_user = User.objects.get(username='old_username') # Replace 'old_username' with the actual username new_user = User.objects.get(username='new_username') # Replace 'new_username' with the actual username update_permissions_for_user(old_user, new_user) However, the problem with this is that get_objects_for_user requires a perms parameter which would require me to hardcode all the perms we wish to copy.

Run management commands on Django server in a Linux hosted App Service in Azure. Anything other than cronjobs?
Please Excuse me if this question has been posted before.I have a linux hosted App Service in Azure running a Django server. I want to run a management command periodically on the server. I am somewhat of an inexperienced person as far as cloud and architechure goes. So please be as elaborate as possible, mentioning the reasoning behind your recomendations, so that I can learn more. Tried using Cronjobs but it was not consistent and I did not have access to logs. Can't use Webjobs since the app service is on a linux machine and webjobs aren't supported on linux machines. Have read that funtions can be used. If so please point me in the right direction on how to setup and connect function to the App service and run command. -

Why is my django-channels project not able to connect to Websockets in my Heroku deployed site?
I've been stuck at this for daaaays now and I realise that solution is probably simple but I no matter how much I read here and try I get the same error...

Payment Intent value is null Stripe Django
I successfully created a checkout session, but when I checked the payment_intent value, it was coming out as null. Here's the code I used: @csrf_exempt def create_checkout_session(request,id): request_data = json.loads(request.body) order = Order.objects.filter(id = id).last() stripe.api_key = PaymentConfig.objects.all().last().stripe_secret_key checkout_session = stripe.checkout.Session.create( # Customer Email is optional, # It is not safe to accept email directly from the client side customer_email=request_data['email'], payment_method_types=['card'], line_items=[ { 'price_data': { 'currency': str(order.amount_type.lower()), 'product_data': { 'name': order.plan.title, }, 'unit_amount': int(order.amount * 100), }, 'quantity': 1, } ], mode='payment', success_url=request.build_absolute_uri( reverse('paymentsuccess') ) + "?session_id={CHECKOUT_SESSION_ID}", cancel_url=request.build_absolute_uri(reverse('paymentfailed')), ) order.stripe_payment_intent = checkout_session['payment_intent'] print(payment_intent) -- **null value** order.save() return JsonResponse({'sessionId':checkout_session.id}) It's essential to get this value and save it in the order object so that I can access the order in the handler view after payment. Here's the handler view's code: class PaymentSuccessView(TemplateView): template_name = "v3/payment-successful.html" def get(self, request, *args, **kwargs): session_id = request.GET.get('session_id') if session_id is None: return HttpResponseNotFound() stripe.api_key = PaymentConfig.objects.all().last().stripe_secret_key session = stripe.checkout.Session.retrieve(session_id) order = get_object_or_404(Order, stripe_payment_intent=session.payment_intent) --**HERE** call=AfterPaymentBackend(request, order.id) ctx = { 'order':order, 'siteInfo':Company.objects.all().last() } return render(request, self.template_name, ctx) Is there something I'm overlooking? Thanks. I tried asking chat GPT for the help but AI isn't that much powerful. I tried searching on google but couldn't find … -
user need to submit the feedback and in my models I'm having user field which is associated with User instance, now don't want to expose my user filed
Users need to submit feedback, and in my models, there's a "user" field associated with a User instance. I want to ensure that this "user" field remains confidential, so it is not identifiable to other individuals when they access the database. Additionally, I need a mechanism to prevent users from submitting feedback more than once. Validation should be in place to ensure that feedback can only be submitted once. Here is what I tried models.py class Trainer_Feedback(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) satisfaction_rate = models.IntegerField() addressed_questions_or_not = models.CharField(max_length=10) were_training_materials_clear_ornot = models.CharField(max_length=10) were_training_engaging_interactive = models.CharField(max_length=10) opportunity_given_to_participate_or_not = models.CharField(max_length=10) training_content_meet_expectation_ornot = models.CharField(max_length=10) complex_concepts_clearly_explained_ornot = models.CharField(max_length=10) which_activity_method_you_found_beneficial = models.CharField(max_length=10) aspects_of_training_which_could_improved = models.TextField() Suggestions= models.TextField() views.py @csrf_exempt def trainer_feedback(request): try: if request.method == 'POST': data = json.loads(request.body) session_id = data.get('session_id') try: user = validate_session(session_id) except ObjectDoesNotExist: return JsonResponse({'message': 'Invalid session ID'}, status=401) existing_feedback = Trainer_Feedback.objects.filter(user=user).first() if existing_feedback: return JsonResponse({'message': 'Feedback already submitted by this user'}, status=400) feedback = data.get('feedback') satisfaction_rate = feedback.get('1') addressed_questions_or_not = feedback.get('2') were_training_materials_clear_ornot = feedback.get('3') were_training_engaging_interactive = feedback.get('4') opportunity_given_to_participate_or_not = feedback.get('5') training_content_meet_expectation_ornot = feedback.get('6') complex_concepts_clearly_explained_ornot = feedback.get('7') which_activity_method_you_found_beneficial = feedback.get('8') aspects_of_training_which_could_improved = feedback.get('9') Suggestions = feedback.get('10') feedback_data = Trainer_Feedback( user=user, satisfaction_rate=satisfaction_rate, addressed_questions_or_not=addressed_questions_or_not, were_training_materials_clear_ornot=were_training_materials_clear_ornot, were_training_engaging_interactive=were_training_engaging_interactive, opportunity_given_to_participate_or_not=opportunity_given_to_participate_or_not, training_content_meet_expectation_ornot=training_content_meet_expectation_ornot, complex_concepts_clearly_explained_ornot=complex_concepts_clearly_explained_ornot, which_activity_method_you_found_beneficial=which_activity_method_you_found_beneficial, aspects_of_training_which_could_improved=aspects_of_training_which_could_improved, Suggestions=Suggestions ) feedback_data.save() … -

I implemented auto save function in my Django 4 web app using js and django view function but it keep saving new model instances at every interval
I have implemented auto save feature in my Django 4 web app using javascript and Django views.py function as the end point.I got it to save the form / model instances to database, bypassing the django forms validation. The problem now is that it keep saving new instances at every interval. The correct behavior is to create the first instance and at subsequent interval only update the database with new data if there has been changes since the last auto save. The problem is i don't know how to store the id of the model instance that was just created so that at every call of the auto save javascript i can check if this auto save request a new request or existing request. I have not tried anything yet at this point. Getting it to this point where I can save the unchecked form/model instance already took a lot of time for me.
