I would like to disable the clickable link only for an object in Django-admin
I would like to disable the clickable link in the django admin object so that the displayed link is only as plain text without <a href ... in HTML. The current code looks like this current situation in the code here is where I would like to disable the clickable link, which would be displayed as plain text e.g. in /csvinput/3c1927f2-9ef6-45b8-a9aa-0021ef64a46f/change/.(of course I would like to keep the functionality for uploading the csv file mean /csvinput/add/) display on page of instance object /csvinput/3c1927f2-9ef6-45b8-a9aa-0021ef64a46f/change/ Many thanks for every thought or idea. -
Django admin page if statements
I'm building a webpage to present sports results but on the admin page I want it, to when a certain sport is set, the points will change to be a certain number of points like this: sports = [ ('Voléi', 'Voleibol'), ('Fut', 'Futebol'), ] team_name = models.CharField(max_length=50, blank=False, null=False, default="") sport = models.CharField(max_length=20, blank=False, null=False, choices=sports) final_score = models.IntegerField(blank=False, default=0) game_date10 = models.DateField() game_description = models.TextField(blank=True, null=True) The Sport is a list of tuples to choose and when you choose, for example, voleibol the final_score field is supposed to change to 1 or 2 points and not infinite, can I do that? -
Cannot find pg_config executable
Having no idea what pg_config is, I searched online and it seems to be part of or connected to PostgreSQL. I don't have or use that though and never have but I suspect that I may be getting this because I recently started using azure libraries in Python (I never had this problem before).

Python class variable is None despite being set
I'm struggling with thread communication in Python. I'm clearly missing something, but I'm new to Python so I don't know very well what I'm doing. When the server gets a GET request, I want it to get two numbers (x and y coords) from a separate thread, which constantly updates those values and to return those numbers as a response. I have a simple Django project with the following structure: it is very basic, made according to tutorial. When the server starts, I start a thread that looks launches my coordinate generator in a separate thread: class GpsMockCoordsServiceConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'gps_mock_coords_service' def ready(self): if os.environ.get('RUN_MAIN', None) != 'true': _thread.start_new_thread(CoordsTracker.launch_recognition, ()) CoordsTracker class looks like so: coords = None class CoordsTracker: #coords = None #tried placin it here, but same effect - it is None when retreived from views.py logger = logging.getLogger("CoordsTrackerLogger") @staticmethod def draw_contours(mask, frame, color): ...... for stuff in stuffs: ......

In Django, what is the better way to pass arguments to a create view?
I need help with two questions. Number one: I have Orders model and generic create view for it and OrderDetails model with create view. After order is created the get_absolute_url method in Orders model redirects to a page with OrderDetails creation form. I want this OrderDetails create view to get arguments from order we just created such as order.pk, now I have to fill this field manually. So, is get_absolute_url method is what I need, or should I override dispatch method in my view, but may be I need to work on get_success_url method? Number two: when I go to Order creation page, how to automatically fill Employee field? E.g. I'm logged in system as Bob Smith and when I create new order I don't want to set myself there manually, I want system do it for me. Here's models: class OrderDetails(models.Model): order = models.OneToOneField('Orders', models.DO_NOTHING, primary_key=True) product = models.ForeignKey('products.Products', models.DO_NOTHING) unit_price = models.FloatField() quantity = models.SmallIntegerField() discount = models.FloatField() class Meta: managed = False db_table = 'order_details' unique_together = (('order', 'product'),) class Orders(models.Model): customer = models.ForeignKey('contractors.Customers', models.DO_NOTHING, blank=True, null=True) employee = models.ForeignKey('employees.Employees', models.DO_NOTHING, blank=True, null=True) order_date = models.DateField(blank=True, null=True) required_date = models.DateField(blank=True, null=True) shipped_date = models.DateField(blank=True, null=True) ship_via = … -

Exe creation using pyinstaller for django rest app
I am trying to create an exe file using Pyinstaller for Django project having only REST api framework used.

I tried --noreload option but still no error and no output at console while exe execution. I am running exe file as: run.exe --noreload (not giving runserver as it is already mentioned in run.py file) Could someone please help on how to create exe file in such scenario and as I am mentioning runserver inside another function? -
Django forms.PasswordInput() updated my application main password
On my Django app, I have a custom field rendered with the forms.PasswordInput() widget. This works as expected from a visual perspective.

How to put template into iframe?
The very similiar problem as mine I found here: Set URL to load iframe in a Django template but it doesn't help. Having a route in my urls.py written as (...) path('rejestracja/', views.rejestracja, name = 'rejestracja'),(...) where the view is to render page named rejestracja.html, I have to put the content of it into iframe. And I do it assigning src = "{% url 'rejestracja' %}". Unfortunatelly the iframe is showing me an error: "Page localhost is blocked" "Server localhost denied connection." ERR_BLOCKED_BY_RESPONSE The strange thing is, source of iframe shows me content of rejestracja.html. It means, I think, my code is ok, but somewhere I have any restrictions. But I have no idea which, how and where... Could someone tell me what is wrong, or at least, where to look for solution? -

Can I change the django rate limiter timeout?
I'm building an API in Python and Django and have encountered the rate limits set by django. Now, I've adjusted the rate limits for users and anons accordingly but I was wondering if there was a way to change or reduce the time in the following error response. { "detail": "Request was throttled. Expected available in 7735 seconds." } Specifically I would like to reduce the 7735 seconds. Also, if I'm not mistaken, the timer counts down from 86400 seconds i.e. 1 day ? -
Better way of hiding entries not created by current user in Django?
Im pretty new to Django, and right now I have created a site that lets users register/login, make entries that are associated to that user via a "user" field in the entries database. Iv'e managed to get all the functionality of hiding other users entries by adding get_queryset() methods that only return the current users entries. But I feel like this is a bad way of doing this. I feel like im reusing a lot of code and that there could be backdoors to display other users entries. Is there a way to completely disable other users entries from the current user, not just not display it? views.py class EntryListView(LockedView, ListView): model = Entry def get_queryset(self): return super().get_queryset().filter(user=self.request.user).order_by("-date_created") class EntryDetailView(LockedView, DetailView): model = Entry def get_queryset(self): return super().get_queryset().filter(user=self.request.user) class EntryCreateView(LockedView, SuccessMessageMixin, CreateView): model = Entry fields = ["title", "content"] success_url = reverse_lazy("entry-list") success_message = "Your new entry was created!" def form_valid(self, form): user = self.request.user form.instance.user = user return super(EntryCreateView, self).form_valid(form) def get_queryset(self): return super().get_queryset().filter(user=self.request.user) class EntryUpdateView(LockedView, SuccessMessageMixin, UpdateView): model = Entry fields = ["title", "content"] success_message = "Your entry was updated!" def get_success_url(self): return reverse_lazy( "entry-detail", kwargs={"pk": self.object.pk} ) def get_queryset(self): return super().get_queryset().filter(user=self.request.user) -
Use of queryset inside Primarykeyfield of ModelSerializer in Django Rest
I am making a simple create api for a model which has almost all fields as foriegn key to other models. I am writing create logic inside the serializer. It is working fine. However if I define all the fields as pkrelated field in serializer, it asks for queryset attribute. Why it is asking that. And if I put queryset and import all the objects(queryset= Example.objects.all()) wouldnt it make the code and api slow since it is importing all the objects from Example model. Also, what its use to be honest? My model: class Example(TimeStampAbstractModel): abc = models.ForeignKey(User,.... xyz_info = models.ForeignKey(XYZ,... mnp = models.ForeignKey(MNP,...... status = models.CharField(....blank=True) My serializer: class AttendanceSerializer(serializers.ModelSerializer): xyz_info = serializers.PrimaryKeyRelatedField(required=True, queryset=XYZ.objects.all()) mnp= serializers.PrimaryKeyRelatedField(required=True, queryset=MNP.objects.all()) #mnp = serializers.IntegerField(required=True) status = serializers.CharField(required=True) class Meta: model = Attendance fields = ['xyz_info','mnp','status'] def create(self, validated_data): ............. In above serializer class, if I hadnt defined all those fileds in the serializer, it works fine.

How to mix multiple querysets into one and re order them by time created?
I am learning Django and still a beginner. For practising, i am trying to make a demo social media website. In my project, users can create groups, then they can post and comment there.

How to create database connection using REST API in Django?
Currently, I'm trying to make a Database Connection with Django REST API. The goal: To create an API for DB connection with any databases by inputting the properties (e.g., host, dbname, username, password, etc). I already tried using GET method to connect and retrieve the output. However, all the DB properties are written in the script. This is my result using GET: Now, I want to modify it into POST method to connect and retrieve the output. (It seems that user gives the input). My expected result is: The problem is: I don't know how to modify it into POST method (request JSON) and retrieve the desired output (response JSON) as I mentioned in the above picture.

Why is the server not working when using django_prometheus?
There is a django application. It is necessary to collect metrics. I'm using django_prometheus. I added the django_prometheus app to my project. INSTALLED_APPS = [ ... 'django_prometheus', ... ] MIDDLEWARE = [ 'django_prometheus.middleware.PrometheusBeforeMiddleware', ... 'django_prometheus.middleware.PrometheusAfterMiddleware', ] I don't want to add the URL "/ metrics". I need to start the server on a separate port using prometheus_client.start_http_server. I added this code to wsgi.py: from django.conf import settings from django_prometheus.exports import SetupPrometheusEndpointOnPort SetupPrometheusEndpointOnPort(9090) This starts the server and it works. But the correct metrics are not displayed. If you add the url "/metrics": urlpatterns += [ path('', include('django_prometheus.urls')), ] Then localhost:8000/metrics will display the correct metrics. What could be the problem? P.S.: I started the server via start_http_server in parallel with the FastAPI application and everything worked correctly. -
