Storing clients card Django
I need to store customer loyalty cards. It should be flexible. I have several variants of cards with different discount systems. For example, the card by amount of purchases - > $100 - 5%, > $1000 - 10%, etc. Or by amount of visits - > 10 - 3%, 100 - 10%, etc. Furthermore, it should store the different image for different types of cards and sales amount, for example 5% - silver colour, 10% - gold, etc. I came up with the idea of storing in in database as JSON. Visits for example: schema = {1: {'discount': 5%, image: '....', 'style': {'background': ..., 'foreground': ...}, 2: {'discount': 10%, image: '....', 'style': {'background': ..., 'foreground': ...}, 3: {'discount': 15%, image: '....', 'style': {'background': ..., 'foreground': ...}, } class ABSCard(models.Model): title = field work_place = field .... class Discount(models.Model): type = .... schema = JSONField abscard_id = ABSCard But I'm not sure that storing JSON in PostgreSQL is the best way. -
Prevent async task from being executed before the rest of the code on Django
Please help me here. This is my django admin class: My problem is, the check_sync_available validation is not working properly because the async task sync_development (redis/celery) is being executed BEFORE the requests.get according to the logs, how can I prevent that? I've tried to use transactions.oncommit and lots of other things and nothing works. class CourseAdmin(nested_admin.NestedModelAdmin): class Meta: model = Course fields = '__all__' actions = ["sync_course_development"] def sync_course_development(self, modeladmin, request, queryset): api_url = f'https://lalala.lalala.la/check_sync_available/' response = requests.get(api_url, headers={'Content-Type': 'application/json'}) if response.status_code != 200: modeladmin.message_user(request, f'A sync is already in progress, try again later.', messages.ERROR) return None else: print(f"Sync available: {response.status_code}") for course in queryset: sync_development.apply_async([course.id]) modeladmin.message_user(request, f'Courses syncing in background. Please reload the page in a while.', messages.SUCCESS) This is the log so you can see what I'm talking about.

How to Make Django Model Choice Field Accept Multiple Criteria
With a model defined as such class Product(models.Model): code = models.CharField(max_length=20, unique=True) name = models.CharField(max_length=100) # intended to be left as NOT unique I would like to pick a product by either its code or its name. For example, if Product 1's code is SUS304 and name Stainless Steel 304, type SUS304 or Stainless Steel 304 in the form should both select this product. I try to use a union queryset as source queryset, but Django complains that .filter after .union is not supported. class OrderForm(forms.ModelForm): codes = Product.objects.annotate(full=F('code')) names = Product.objects.annotate(full=F('name')) product = forms.ModelChoiceField(codes.union(names), to_field_name='full') class Meta: # Order is another model that have a ForeignKey to Product model = Order fields = ['product'] How can I achieve this (especially in Django's way)? PS1. It is possible that multiple products share the same name, or one product's name is another's code. In such case, I would expect a ValidationError. PS2. Despite the length limit, there is no effective way to determine if a given string is a code or a name. SUS304 could also be a product's name. -
Does wagtail support dynamical definition of Search and Social Previews or Slug?
Is there any system in wagtail where you can dynamically define Search and Social Previews or Slug. so for example that it goes details/1/ where one would represent certain ID. so it would be details/{id} I wonder is this possible. If this is not possible is it possible somehow to define query in route? Thanks in advance guys. Currently I am solving this problem with keeping in session my id and using it later in my blocks.py but I would like for the Id to be vissible in the route. Example: https://www.my-website.com/orders/2/ Where 2 would be dynamically forwarded. -
Should I subclass my django model or not?
I'm creating a simple forum app in order to learn django. The idea is to create as much a full featured forum as I can over time, but for now this is what I have: class Post(models.Model): post_body = models.TextField(max_length=2000) publish_date = models.DateTimeField("date posted") author = models.TextField(max_length=200) # link to User model later class Meta: abstract = True # Post that starts a thread class ThreadPost(Post): post_title = models.Charfield(200) is_solved = models.BooleanField("is_issue_solved", default=False) class ReplyPost(Post): is_solution = models.BooleanField("is_this_the_solution", default=False) thread_post = models.ForeignKey(ThreadPost, on_delete=models.CASCADE) I'm unsure if this this is overdoing it a bit. ThreadPost and ReplyPost are so similar. Should I instead just create two separate classes which are unrelated through inheritance? Should I just have one Post class and just make the post_title optional when it's a reply? I guess the singular Post class would have to have a recursive relation too in that case (0 to N). Also, in future I want to add other features like reactions (e.g. thumbs up/down, laugh etc.), ability to report a post etc. Which I think could be a seperate model that links Post and User and would have its own fields. I wonder what approach would be best to keep the … -

Django cache requests and only allow refresh daily
So I have this Admin dashboard for an e-commerce website where there are all kinds of statistics about sales and customers. Now this data is hosted in AWS RDS and the dashboard is made with django templates. So logically whenever the admin goes to this page it gets refreshed and it queries the AWS RDS. Now this data does not change in real-time the dashboard data gets updated daily in the database (this is done with dbt so this has nothing to do with django) so it doesnt make sense to run these queries multiple times a day because the data will not change on the dashboard. So what I need is something to cache the data once the admin goes to this dashboard and then invalidate the cache at say midnight. Anyone has done something like this or has any advice on how to create something like this? Thanks in advance for all replies! -

systemctl and uwsgi issue for remote django app

The errors do not happen when I run the server manually. And the uwsgi.service file worked fine until this morning so I don't know what is happening all of a sudden. help me please?

Django object.values with alias / translation?
Is it possible to use something like an alias name for a django model attribute and a translation too? For example, one has a model like this: class TestModel(models.Model): field1 = models.CharField( args="Source (U)ID", max_length=150, help_text="Some helptext", ) field2.... field3.... Now you access the model in a view like this: transactions = ( Transaction.objects.all() ) transactions.values( Id=F("field1"), Json=F("field2"), BookingDate=F("field3"), ) Here we use an alias, but I have to specifically pick the values by hand and set them every time. Is there a better way to do that? A translation would be very useful too, since the data will be passed to a template and a table will be rendered with the data. So there is no good way to do it in the templates since the template doesn't know what fields it gets. It just renders what it gets. So the translation has to happen in the view/model somehow. Thanks! -

One of these tests looks like this; @pytest.fixture def oauth_data(db): test_region = Region.objects.create( name="MyRegion", iso_code_short="MYR", iso_code_long="MYREG" ) app_owner = USER_MODEL( username="app-owner", email="owner@somewhere.com", gender="M", date_of_birth="1970-1-1", region=test_region, first_name="John", last_name="Doe", ) app_owner.set_password("password") app_owner.save() app_redirects = "http://site1.com/return\r\nhttp://site2.com/back" app = Application.objects.create( name="My Test Client", client_id="test-app", client_secret="password", client_type=Application.CLIENT_CONFIDENTIAL, authorization_grant_type=Application.GRANT_PASSWORD, user=app_owner, skip_authorization=True, redirect_uris=app_redirects, ) return {"app": app, "app_owner": app_owner} # some test class here... def ( self, oauth_data, client, settings ): mixin = AccessTokenGeneratorMixin() tokens = mixin.get_access_token(oauth_data["app"], oauth_data["user"]) url = reverse("oauth2_provider:token") response = client.post( url, data={ "client_id": oauth_data["app"].client_id, "client_secret": oauth_data["app"].client_secret, "grant_type": "refresh_token", "refresh_token": tokens["refresh_token"], }, ) assert 200 == response.status_code Is there something in v2 (that I've missed in the release notes) that invalidates this fixture to create an invalid client!? -
Django unable to destroy test DB
I made a REST framework project in Django using Docker. All of the tests passed without issue. Then I had to move the project "out" of Docker. Not sure if this is an important detail, but just in case. I created a PostgreSQL on Aiven and connected my project to it. It all works, except one test fails and also, after running them, I get this message: File "/Users/john/programation/python3/recipe-app-api-out/recipe_env/lib/python3.12/site-packages/django/db/backends/utils.py", line 82, in _execute return self.cursor.execute(sql) ^^^^^^^^^^^^^^^^^^^^^^^^ django.db.utils.OperationalError: cannot drop the currently open database Do you know why this is happening now? I'm also not sure if the test failing and the dropping issue have to do. The test failing creates and uploads an image, and then tries to delete it with the TearDown method. Let me know if there is some specific part of the code I should share to add useful context to the question. -
Getting error for django and react native code Forbidden (CSRF token missing.):
I am working on a Django backend to handle some data manipulation, specifically appending and deleting data. My code works perfectly when tested with Postman, but I encounter a 403 Forbidden error when trying to access the /bookings/remove/ endpoint from my React Native frontend. Here's the error message I receive: Forbidden (CSRF token missing.): /bookings/remove/ "POST /bookings/remove/?booking_id=148/ HTTP/1.1" 403 Interestingly, all other endpoints are working fine without any CSRF-related issues. It's only this specific endpoint that is causing problems. Django Backend i have my settings for cors as follows: INSTALLED_APPS = [ 'corsheaders', "all other apps" ] SESSION_COOKIE_SECURE = False SESSION_COOKIE_SAMESITE = None SESSION_COOKIE_AGE = 1209600 CORS_ALLOW_ALL_ORIGINS = True MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication', 'rest_framework_simplejwt.authentication.JWTAuthentication', ], 'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination', 'PAGE_SIZE': 10, } and my endpoint for which i am getting error is @api_view(["POST"]) @permission_classes([IsAuthenticated]) @csrf_exempt def cancel_the_booking(request, booking_id): try: if not booking_id: return Response({"error": "Booking ID is required"}, status=status.HTTP_400_BAD_REQUEST) booking = Booking.objects.get(booking_id=booking_id) if booking.host_id != request.user.id: return Response({"error": "You are not authorized to cancel this booking", "host": request.user.id}, status=status.HTTP_403_FORBIDDEN) for date_price in booking.dates_price.all(): AdSpaceDates.objects.create( ad_space=booking.space_id, available_from=date_price.available_from, available_to=date_price.available_to, price=date_price.price ) booking.delete() return Response({"success": "Booking cancelled and dates are now … -
How to add multiple forms to Django view if one is ChatGPT input?
I like to add two separate forms into one view what is not a big deal but I can't find where is the stuff what makes an error and both of the forms works not.

ChatGPT form say: An error occurred. Please try again.

Django TestCase slef.client.patch gives a 404 error
I want to test the update function of a view set from rest_framework.viewsets import ModelViewSet @extend_schema(tags=['Customers']) class CustomerViewSet(ModelViewSet): """ This view can be used to see all the customers""" serializer_class = CustomerSerializer ..... def update(self, request, *args, **kwargs): return self._update_customer(request, *args, **kwargs) The route is mapped here (like the other view sets): router.register(r'customers', CustomerViewSet, basename='customer') Like for my other view sets where it works, i test the update method by resolving it in my test case from django.test import TestCase from rest_framework.reverse import reverse ...... class CustomerUpdateViewTest(TestCase): ..... def test_customer_missing(self): url = reverse('customer-detail', [2]) token = create_access_token(self.my_user) data = { 'customer': 'new name customer' } response = self.client.patch(url, data, content_type="application/json", HTTP_AUTHORIZATION=f'Bearer {token}') I have created before in a setup method many customers But the self.client.patch instruction give always a 404 error In my running application, the path is /api/customers/x (like in my test where x = a customer identifier) and is an HTTP PATCH verb For my similar views, i test in a very similar way and it works. Do you have already encountered such a problem ? If yes, what can i do to solve this problem ? Thank you very much in advance, Thomas -
VS Code not jumping to the top stack frame
I'm trying to debug some Django library code with the default VS Code Python and Django debugging settings (and "justMyCode" = True). I've set a breakpoint in one of the library functions: I call this from some user code, eg. formset.save(). When I debug and hit the breakpoint, VS Code jumps to this user code instead of the library code as I'd have expected: Pressing "Step Into" seems to progress the library code, but keeps jumping back to the user code which is calling it. The call stack seems to know about the library code, although it is greyed out: If I click on save then the currently executing statement is highlighted: I can go through the tedious process of stepping through, clicking the top stack frame, and then doing usual things like inspecting locals. The issue just seems to be about where VS Code is jumping to every time the debugger breaks (or maybe where pdb is telling VS Code to jump -- I'm not sure). I want the library code which is currently being executed to be jumped to, and that's what I would have expected to happen.
