Django Multi Combination Model Joins
Currently experiencing a problem where my models aren't joining on the foreign key properly, Doctors can only have one toolset, essentially I need to return [DoctorName, Category, Type, Subtype, Syringe, Bandage] ToolSetCategoryID, ToolSetTypeID, ToolSetSubTypeID all join on each other's respective tables and all join back to ToolSets an example of the models would be: class Doctor(models.Model): DoctorID = models.AutoField(db_column='DoctorID', primary_key=True) ToolSetID = models.ForeignKey("ToolSets", db_column='ToolSetID', on_delete=models.CASCADE) DoctorName = models.CharField(db_column='DoctorName', max_length=100) class Meta: managed = False db_table = 'tblDoctors' default_permissions = ['add','edit','delete'] class ToolSetCategories(models.Model): ToolSetCategoryID = models.AutoField(db_column='ToolSetCategoryID', primary_key=True) Category = models.CharField(db_column='Category', max_length=100) class Meta: managed = False db_table = 'tblToolSetCategories' default_permissions = ['add','edit','delete'] class ToolSetTypes(models.Model): ToolSetTypeID = models.AutoField(db_column='ToolSetTypeID', primary_key=True) ToolSetCategoryID = models.ForeignKey("ToolSetCategories",db_column='ToolSetCategoryID',on_delete=models.CASCADE) Type = models.CharField(db_column='Type', max_length=100) class Meta: managed = False db_table = 'tblToolSetTypes' default_permissions = ['add','edit','delete'] class ToolSetSubTypes(models.Model): ToolSetSubTypeID = models.AutoField(db_column='ToolSetSubTypeID', primary_key=True) ToolSetTypeID = models.ForeignKey("ToolSetTypes",db_column='ToolSetTypeID',on_delete=models.CASCADE) ToolSetCategoryID = models.ForeignKey("ToolSetCategories",db_column='ToolSetCategoryID',on_delete=models.CASCADE) SubType = models.CharField(db_column='SubType', max_length=100) class Meta: managed = False db_table = 'tblToolSetSubTypes' default_permissions = ['add','edit','delete'] class ToolSets(models.Model): ToolSetID = models.AutoField(db_column='ToolSetID', primary_key=True) ToolSetCategoryID = models.ForeignKey("ToolSetCategories",db_column='ToolSetCategoryID',on_delete=models.CASCADE) ToolSetTypeID = models.ForeignKey("ToolSetTypes",db_column='ToolSetTypeID',on_delete=models.CASCADE) ToolSetSubTypeID = models.ForeignKey("ToolSetSubTypes",db_column='ToolSetSubTypeID',on_delete=models.CASCADE) Syringe = models.CharField(db_column='Syringe', max_length=100) Bandage = models.CharField(db_column='Bandage', max_length=100) class Meta: managed = False db_table = 'tblToolSets' default_permissions = ['add','edit','delete'] -

Django Rest Framework app security preparation for production
Intro I've built a web application with multiple services: frontend (react) backend (API and admin panel) (Django Rest Framework + simple jwt auth) Redis, DB, Nginx and etc Kubernetes cluster The app isn't small like 60k+ lines of code. It's a startup. I mentioned it to let you know that probably I wouldn't have that much attention from hackers or traffic at all. Hence I have a space to improve gradually. The auth is done with DRF simple jwt library. Expiring Access + Refresh token. Problem statement I did a security audit and found imperfections from the security architecture perspective. I don't know how those issues are crucial, how should I fix them, or what issues can be fixed later. So I'm seeking solutions and advice. I would prefer an optimal proportion between the speed and quality rather than quality only (If I miss about that let me know) hence if something is "nice to have" rather than "important" I would put it to the backlog of next releases. The actual list of issues Let's refer by its number if you want to. #1 Authentication methods My current setup: REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication', … -

How to insert data in child table from react to django rest framework models
I'm new to React and Django rest framework. I want to insert profile data into the Django model using fetch API in react. I'm continuously getting response header as: {"user":["Incorrect type.

Uploading images with HTMX in django
I am trying to implement image adding functionality through HTMX. Adding the photo is no problem. However, once the photo is added in the view, the image link does not show up. It looks like no photo has been added but when I hit the refresh button, the link is being displayed. What I am trying to achieve is that, once the photo is uploaded and the form is saved, I want the link to show up to confirm for the user that their photo is uploaded. This is my form template <form action='' method="POST" class="form" hx-post='' hx-swap='outerHTML' enctype="multipart/form-data" hx-post="{{request.path}}" hx-encoding="multipart/form-data"> {% csrf_token %} {% for field in form %} <div class="form-group"> {{field}} </div> {% endfor %} <div class='htmx-indicator'>Loading...</div> <div class="text-center"> <button class='htmx-inverted-indicator' style='margin-top:10px;' type='submit' >Save</button> </div> {% if message %} <p>{{ message }}</p> {% endif %} </form> I am then including this template in the update template. Is there anyway to get the wished result without using JavaScript? -
Getting null when doing request from browser but it is not null when same is done using postman
I am using django as a backend, React as frontend and cloud firestore is my DB.

Django ORM - Condition or Filter on LEFT JOIN
I will try to be precise with this as much as possible. Imagine these two models. whose relation was set up years ago: class Event(models.Model): instance_created_date = models.DateTimeField(auto_now_add=True) car = models.ForeignKey(Car, on_delete=models.CASCADE, related_name="car_events") ... a lot of normal text fields here, but they dont matter for this problem. and class Car(models.Model): a lot of text fields here, but they dont matter for this problem. hide_from_company_search = models.BooleanField(default=False) images = models.ManyToManyField(Image, through=CarImage) Lets say I want to query the amount of events for a given car: def get_car_events_qs() -> QuerySet: six_days_ago = (timezone.now().replace(hour=0, minute=0, second=0, microsecond=0) - timedelta(days=6)) cars = Car.objects.prefetch_related( 'car_events', ).filter( some_conditions_on_fields=False, ).annotate( num_car_events=Count( 'car_events', filter=Q(car_events__instance_created_date__gt=six_days_ago), distinct=True) ) return cars The really tricky part for this is the performance of the query: Cars has 450.000 entries, and Events has 156.850.048. All fields that I am using to query are indexed. The query takes around 4 minutes to complete, depending on the db load. This above ORM query will result in the following sql: SELECT "core_car"."id", COUNT("analytics_carevent"."id") FILTER (WHERE ("analytics_carevent"."event" = 'view' AND "analytics_carevent"."instance_created_date" >= '2022-05-10T07:45:16.672279+00:00'::timestamptz AND "analytics_carevent"."instance_created_date" < '2022-05-11T07:45:16.672284+00:00'::timestamptz)) AS "num_cars_view", LEFT OUTER JOIN "analytics_carevent" ON ("core_car"."id" = "analytics_carevent"."car_id") WHERE ... some conditions that dont matter GROUP BY "core_car"."id" … -
Is it possible to make 'cart' with django Class Based View?
I am trying to make a simple e-commerce website and followed some tutorials.

How to clear this user-role permissions overlap in my Django API project?
Project setup: I am working on a project where we’re developing a role-based access for users. This means that user_1 is role (group) “Supervisor” and has certain permissions, whereas user_2 is role “User” and has less permissions. These permissions are already defined (we were given a matrix of the permissions of each role). A permission is a collection of endpoints. Models: The User model is in a M2M relation with the Group and Permission models. The Group model is in a M2M relationship with the Permission model and the Permission model itself is in a M2M relationship with the Endpoint model. Flow: Users are assigned 0 or more groups. A group is consisted of 0 or more permissions. A permission is consisted of 0 or more endpoints. Tech stack: Django (DRF API) as a backend, vue.js frontend. Problem: Upon visiting "Page X" on the front end, the app hits endpoints "/api/endpoint-1" and "/api/endpoint-2/" in order to collect the necessary data. The user with role "User" should see all contents of this page. However, then the user with role "User" decides to visit "Page Y". There the app hits the same endpoint "/api/endpoint-1/" but the user should have no access to … -

How to filter using get_queryset in Django Rest Framework?
Currently, the API I'm pulling is as such: http://127.0.0.1:8000/api/locs/data/2 and the output is as such: { "id": 2, "date": "2019-01-07", "hour": null, "measurement": null, "location": 6 } What I want is actually filtering by the location value, so from the API url above, I would love to pull all the data that is from location: 2. How can I achieve that? What I have so far: views.py class LocationDataView(viewsets.ModelViewSet): serializer_class = LocationDataSerializer permission_classes = [IsAuthenticated] authentication_classes = [TokenAuthentication] def get_queryset(self): queryset = LocationData.objects.all() pk = self.kwargs['pk'] queryset = queryset.filter(location=pk) def perform_create(self, serializer): serializer.save() and urls.py from django.urls import path, include from rest_framework import routers from . import views router = routers.DefaultRouter() router.register(r'locs', views.LocationListView, 'locs') router.register(r'locs/data', views.LocationDataView, 'locs/data') urlpatterns = [ path('', include(router.urls)), path('locs/forecast-data/', views.getForecastData, name='forecast-data'), ] My question is that, how can I access the pk for the location? -
