How to add multiple fields' reference to "unique_together" error message
I have a model with multiple fields being checked for uniqueness: class AudQuestionList(BaseTimeStampModel): aud_ques_list_id = models.AutoField(primary_key=True,... aud_ques_list_num = models.CharField(max_length=26,... aud_ques_list_doc_type = models.ForeignKey(DocType,... short_text = models.CharField(max_length=55,... aud_scope_standards = models.ForeignKey(ScopeStandard, ... aud_freqency = models.ForeignKey(AuditFrequency, ... aud_process = models.ForeignKey(AuditProcesses, ... unique_together = [['aud_scope_standards', 'aud_freqency', 'aud_process',],] My model form is as described below: class CreateAudQuestionListForm(forms.ModelForm): class Meta: model = AudQuestionList fields = ('aud_ques_list_doc_type', 'aud_scope_standards', 'aud_freqency', 'aud_process', 'short_text', ... def validate_unique(self): try: self.instance.validate_unique() except ValidationError: self._update_errors({'aud_scope_standards': _('Record exists for the combination of key values.')}) The scenario works perfectly well, only that the field names (labels) itself are missing from the message. Is there a way to add the field names to the message above, say something like: Record exists for the combination of key fields + %(field_labels)s. -
Docker-Compose Init Postgres Failing
I've been attempting to make a docker-compose file work, and so far it's been closer and closer, but not quite there. Maybe asking the questions will be useful to someone else in the future. Anyway, the previous thread was here: Docker-Compose Postgresql Init Entrypoint From which I learned, between runs a docker-compose file should have docker compose volumes --down and if the POSTGRES_DATABASE isn't specified, then the POSTGRES_NAME will replicate to the POSTGRES_DATABASE. another suggestion from Discord has been to rewrite some of the volume signature to include the file path to init.sql as in docker-entrypoint-initdb.d/init.sql So if I docker-compose down --volume and then sudo docker-compose build && docker-compose up with version: "3.9" services: db: restart: always image: postgres volumes: # - ./data/db:/var/lib/postgresql/data - ./init.sql:/docker-entrypoint-initdb.d/init.db environment: - POSTGRES_NAME=dev-postgres - POSTGRES_USER=pixel - POSTGRES_DATABASE=lightchan - POSTGRES_PASSWORD=stardust web: build: . restart: always command: sh -c "./waitfor.sh db:5432 -- python3 manage.py runserver" volumes: - .:/code ports: - "8001:8001" environment: - POSTGRES_NAME=dev-postgres - POSTGRES_USER=pixel - POSTGRES_DATABASE=lightchan - POSTGRES_PASSWORD=stardust depends_on: - db Then the following is output: Attaching to lightchan-db-1, lightchan-web-1 lightchan-db-1 | The files belonging to this database system will be owned by user "postgres". lightchan-db-1 | This user must also own the server process. … -

Django object update using htmx and SingleObjectMixin
I'm using htmx for the first time. I have a table where each cell is a grade object. Previous to htmx I made each cell a link to an UpdateView for the object. I am now trying to have the user modify the the object's score field directly in the table using htmx. I'm sure I'm doing several things wrong. My page loads as expected and the table is displayed as expected. when I type in a cell, I get an error Forbidden 403. CSRF Verification Failed. The purpose of this post/question is to figure out how to get past this 403 error. Having said that, if it turns out that I'm going down the completely wrong path with using a SingleObjectMixin, please let me know.

How test the presence of CSRF in an APIView (DRF)?
I have an API, with JSON as content-type, built with Django Rest Framework. There is an endpoint which permit login the users, for that I am using simple-jwt package, and how the view has permission_classes = [AllowAny] and works through POST method to make the login, so I added the CSRF token to this view: @method_decorator(csrf_protect, name='post') class TokenCookieObtainPairView(TokenObtainPairView): ... When the header and cookie that have the CSRF doesn't match, a template of django (views.csrf.csrf_failure) return a 403 status, but I overrided that (method finalize_response()) to return a message to the consumer. if response.status_code == status.HTTP_403_FORBIDDEN: serializer = MessageSerializer({'message': self.MESSAGE}) new_response = Response(serializer.data, status=status.HTTP_403_FORBIDDEN) return super().finalize_response(request, new_response, *args, **kwargs) I created a test for that view. I am using pytest and the DRF's APIClient. from pytest import mark, fixture @fixture def api_client_csrf() -> APIClient: return APIClient(ensure_csrf_checks=True) @mark.django_db def test_login_view_csrf(api_client_csrf): """Verify that the 'login' view need the CSRF_token.""" path = reverse_lazy('login') credentials = { 'email': 'xxx@yyyy.com', 'password': '******' } response = api_client_csrf.post(path, data=credentials) print(response.data) assert response.status_code == 403 The test failed because the CSRF token is not required and the credentials are invalid, hence pytest return: assert response.status_code == 403 E assert 401 == 403 E +401 E -403 The … -

Using CreateView with 2 Models at the same time
I am learning django. I am attempting to create a website that logs a user's workout. The user will be able to make premade workouts. For each workout routine, there will be a workout name and it will consist of different exercises and the number of sets per exercise. In order to achieve this, I have created a custom through model so I can associate a number of sets to each exercise for that premade workout routine. The trouble I am having is that in order to create a workout routine I need to use the WorkoutRoutine model in order to create a WorkoutRoutine object. Then I also need to use SetAmount in order to assign an exercise associated with a number of sets to the WorkoutRoutine. Here is my models.py: from django.db import models from django.contrib.auth import get_user_model from django.core.validators import MaxValueValidator, MinValueValidator class WorkoutRoutine(models.Model): title = models.CharField(max_length=25) owner = models.ForeignKey( get_user_model(), on_delete=models.CASCADE, ) exercise = models.ManyToManyField( 'Exercise', through='SetAmount', related_name='workoutRoutines' ) def __str__(self): return self.title class Exercise(models.Model): name = models.CharField(max_length=25) def __str__(self): return self.name class SetAmount(models.Model): workout_routine = models.ForeignKey( 'WorkoutRoutine', related_name='set_amounts', on_delete=models.CASCADE, null=True ) exercise = models.ForeignKey( 'Exercise', related_name='set_amounts', on_delete=models.SET_NULL, null=True, blank=True ) set_amount = models.IntegerField( default=0, validators=[ MaxValueValidator(100), … -

Django, Manage threads and websocket for a data visualisation website
I am a Django beginner and here is the project : I am building a data visualisation website. I am loading a continuous data stream and I want the client to be able to choose the data processing to apply (in python, IA treatments with tensorflow for example). Once the treatments are chosen by the client, I want to be able to launch them in a thread and send the results to the client every X seconds in a websocket (and be able to process websocket messages coming from the client at the same time). I have already done it with Flask but I don't succeed with django. I have followed many tutorials, in particular this one, which seem similar to I want to do : https://www.neerajbyte.com/post/how-to-implement-websocket-in-django-using-channels-and-stream-websocket-data The main issue is that I don't know how or even where create my thread. I can't do it in an AsyncWebsocketConsumer class, because it doesn't allow me to launch a thread which is able to send a Websocket request (I need to launch a async function to be able to send a request and I can't launch a async function in a thread).

Django app running fine on localhost, but not working on elastic beanstalk 500 internal errors
I have a django app, and it works fine on localhost (no problems). It loads a json file into a data structure (Trie), and is being used in a single route. It takes about 2-3 seconds for the file to be read, and build the Trie (there are thousands of words in my list). All of this is fine localhost as it only takes 2-3 seconds a single time (when you start the server). Then when you call a route on the front end with a POST to the route it performs the search on the Trie and returns the results (OK). Everything works fine localhost. However whenever I try this same exact approach on AWS Elastic Beanstalk, it returns 500 Internal Server Error on every route (routes that don't use this Trie are also throwing this exact same error code).
