Can't delete old objects after adding new one in django

Listening onchange events on a dropdown to update a chart data list
I'm trying to figure it out how can I create an onchange event to listen to the value from the dropdown, so the chart will change it values depending on that id, for that I have the following elements: In views.py: def html(request, filename): #Data for the graph id = list(Device.objects.values_list('patientId', flat=True).distinct()) labels = list(Device.objects.values_list('hour', flat=True)) glucose_data = list(Device.objects.values_list('glucoseValue', flat=True)) data = glucose_data formatted_data = select_formatted_date(labels) lastPatientData = Device.objects.filter(patientId = id[-1]) #the last element added hourArray = [] glucoseArray = [] for item in lastPatientData: lastPatientHour = Device._meta.get_field('hour') lastPatientGlucose = Device._meta.get_field('glucoseValue') formattedHour = lastPatientHour.value_from_object(item) frt_hour = formattedHour.strftime('%Y-%m-%d %H:%M:%S') formattedGlucose = lastPatientGlucose.value_from_object(item) hourArray.append(frt_hour) glucoseArray.append(formattedGlucose) device_list = list(Device.objects.all()) for device in device_list: print(device) #f = DateRangeForm(request.POST) context = {"filename": filename, "collapse": "", "hourArray":hourArray, "glucoseArray": glucoseArray, "patientId": id, "dataSelection": formatted_data, "deviceList": device_list, "labels": json.dumps(labels, default=str), "data": json.dumps(data) } return render(request, f"{filename}.html", context=context) In forms.py, I have this, but I really don't know what to do with this data: from django import forms idsList = forms.ModelChoiceField(queryset = Device.objects.values_list('patientIId'),widget = forms.Select(attrs = {'onchange' : "myFunction()"})) my model is: class Device (models.Model): patientId = models.IntegerField(unique=True) deviceId = models.CharField(unique=True,max_length=100) hour = models.DateTimeField() type = models.IntegerField() glucoseValue = models.IntegerField() And in the index.html, I have the following(in data … -
How to set API keys for non-authentication models in Django?
I am developing an inventory tracker for stores, where each store can have multiple outlets. I am using Django with the Django Rest Framework. Each store is an authentication model. As such, it can manage its respective outlets and settings by logging into the system. In the current state, each outlet uses the same token of the store model (provided by DRF) to connect and update inventory as sales are made. In my opinion, this creates a security vulnerability. For example, if a store has hundreds of outlets and one of the outlets' API key is exposed, all the outlets are exposed. Is there some way to generate an authentication token for each outlet? This way the stores can manage and, if required, renew the token of each outlet. Also, how would I validate this token in the DRF views and/or serializer? -
DRF: Creating mixin using different serializers & objects
I have two APIView classes with almost similar behaviour (and code). Different are only serializers and models object (Favorite & FavoriteSerializer for first class and PurchaseList and PurchaseListSerializer for second). As far as I understand it is a perfect usecase for mixin, according to DRF docs ([DRF: Creating custom mixins] 1https://www.django-rest-framework.org/api-guide/generic-views/). Unfortunately, I'm struggling with how to define mixin without the definition of serializer & obj in it. class FavoriteViewSet(APIView): def get(self, request, recipe_id): user = request.user.id data = {"user": user, "recipe": recipe_id} serializer = FavoriteSerializer( data=data, context={"request": request}, ) serializer.is_valid(raise_exception=True) serializer.save() return Response(serializer.data, status.HTTP_201_CREATED) def delete(self, request, recipe_id): user = request.user favorite_recipe = get_object_or_404( Favorite, user=user, recipe__id=recipe_id ) favorite_recipe.delete() return Response( "Рецепт удален из избранного", status.HTTP_204_NO_CONTENT ) class PurchaseListView(APIView): def get(self, request, recipe_id): user = request.user.id data = {"user": user, "recipe": recipe_id} serializer = PurchaseListSerializer( data=data, context={"request": request} ) serializer.is_valid(raise_exception=True) serializer.save() return Response(serializer.data, status.HTTP_201_CREATED) def delete(self, request, recipe_id): user = request.user purchase_list_recipe = get_object_or_404( PurchaseList, user=user, recipe__id=recipe_id ) purchase_list_recipe.delete() return Response( "Рецепт удален из списка покупок", status.HTTP_204_NO_CONTENT ) -
Having conflicting groups in Django Group Model
I have different groups in my Django Groups: for example: named Moderator and Reviewer. What I want to do is, if a user is in Moderator Group, the user shouldn't be in Reviewer Group. Now, I know that I can do this in different places like save_model() in ModelAdmin, etc. However, I want to prevent the assignment option in the Django Admin panel where you can assign users the groups and permissions as in below group selection. -

Optimize Django tests with preloaded database
I am trying to reduce my CI usage and make my code cleaner by pre-loading my test database using a custom class. I had multiple files/classes that looked like this: class TestSomething(TestCase): def setUp(self): User.objects.create(...) def test_something(self): pass I converted them into: class TestSomething(PreloadedTestCase): def test_something(self): pass with a common PreloadedTestCase class: class TestSomething(TestCase): def setUp(self): User.objects.create(...) This does make the code cleaner and removes a lot of duplicate lines, but it seems to increase the CI execution time. Is PreloadedTestCase.setUp() run multiple times? If so, how can I have a common class that is run only once against the database? I looked into fixtures but it is only populating the database, I would have to query it to access my objects in the tests. -
What's the default value for a DecimalField in Django?
I'm adding a new DecimalField to my model, what value will it have by default in the database (if I don't specify the default explicitly)? amount = models.DecimalField(max_digits=15, decimal_places=3) I'm expecting it will be either NULL or 0.0 (or None or Decimal(0.000) in python), but which? Couldn't find this mentioned in the docs: https://docs.djangoproject.com/en/2.2/ref/models/fields/#decimalfield I'm using Django 2.2, but expect this is consistent across versions. -

Django 4 and Unittest loader
We use Django for an online webshop, and want to upgrade to Django 4. However, since upgrading on a test branch, we have a problem, that I will highlight here. We serve two different markets, lets call them Market A and B :) Since these two markets can have different functionalities, our INSTALLED_APPS gets populated like so: MARKET_SPECIFIC_APPS = { MARKET_A: [ 'market_a.apps.MarketAConfig', 'payment_system_a.apps.PaymentSystemAConfig' ], MARKET_B: [ 'market_b.apps.MarketBConfig', 'payment_system_b.apps.PaymentSystemBConfig', ], } if MARKET in MARKET_SPECIFIC_APPS: # If there is a market-specific app, add it to INSTALLED_APPS INSTALLED_APPS += MARKET_SPECIFIC_APPS[MARKET] However, when running MARKET specific tests for each market, only MARKET_A passes. MARKET_B now throws an error, since upgrading from Django 3.2 to Django 4 RuntimeError: Model class payment_system_b.models.payment.Payment doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. Meaning, this test is still run, and the test runner includes it in INSTALLED_APPS even tho it shouldnt. Is there any change from the Django 4 changelog im missing about this? Running these market-specific tests was working fine before upgrading to Django 4 -

Django template won't respond to css file , worked briefly yesterday
It is exactly how it sounds. My main goal is to make the css file work with django template so I can design my templates. Yesterday I tried and initially my folder structure was wrong. I placed static folder in myapp folder. Didn't work. I tried putting it in templates folder. It only worked when I had 2 static folders both in myapp and templates folder. Realized it isn't a working solution. I placed a single static folder with a css file in it in mysite folder, at the same level with myapp folder and everything seemed to work. Satisfied I left at that. Today I came back to it and it stopped working. It seems to be frozen. Not responding to the new codes. Old colors are showing but new colors aren't, which is odd. Tried changing the old colors, it won't change. Literally my css file has a class name .intro where I changed the color from purple to red, my template still showing purple which I set yesterday. My template shows no error and all the texts and divs I am adding are updating with no issue.Kind of lost where I may have gone wrong. Certainly don't … -
How to open a modal when moving a page
