Why am I getting django.db.models error telling me I have no attribute for TextChoices in Django (3.1.6) and Python(3.8)?

Display the error_messages under the fields
I'm using this package for my form https://github.com/KuwaitNET/djvue but anyway it's like a general question, I've wrote the following method to validate my phone number field def validate_phone_number(self, value): phone_number = to_python(value) if phone_number and not phone_number.is_valid(): self.fields["phone_number"].error_messages.update({"ph":"Wrong"}) raise ValidationError(_(u'The phone number entered is not valid.')) return value and it works just fine because in my Model: def serve(self, request, *args, **kwargs): if request.method == "POST": data = json.loads(request.body) serializer = ContactUsSerializer(data=data) if serializer.is_valid(): ticket_number = serializer.save() return JsonResponse({"ticket_number": ticket_number}) else: return JsonResponse(serializer.errors) ctx = self.get_context(request, *args, **kwargs) ctx["serializer"] = ContactUsSerializer() request.is_preview = getattr(request, "is_preview", False) return TemplateResponse( request, self.get_template(request, *args, **kwargs), ctx ) and actually when I enter an invalid phone number I'm getting a JsonResponse with the error: 0: "The phone number entered is not valid." which is great, but how can I display the updated error message below the phone_number field?? it looks like despite the errors are being updated the displaying is not, should I use Vue or something to achieve that? knowing that the package I'm using does so: <span class="help-block text-danger" v-for="error in errors" :key="error">{( error )}</span> but I'm not sure how and where they render the error, so I want maybe a pure … -

How to warmup cache view as login user in Django?
I want to warmup cached View from scheduled management command. I have to be logined when doing request to View. What is the best practice to login as user and do get request to View? I am thinking about two ways: Use requests: request = requests.session() response = request.get(login_url) token = response.cookies['csrftoken'] data={'username':'username@username.ru', 'password': 'pass','csrfmiddlewaretoken':token} response = request.post(login_url, data=data) response = request.get(target_url) Use test.Client() and login option. What is better? Or maybe the best option exists? -
Update Django model based on the row number of rows produced by a subquery on the same model
I have a PostgreSQL query which updates the global_ranking field of each row, based on the row number of that row as computed by a subquery which takes that same table and sorts it according to another column called rating. Additionally, the update is partitioned, so that the ranking of each updated row is relative to only those rows which belong to the same language. In short, I'm updating the ranking of each player in a word game (why player statistics have a language field), based on their current rating. The working PostgreSQL query looks like this: UPDATE stats_userstats SET global_ranking = sub.row_number FROM ( SELECT id, row_number() OVER ( PARTITION BY language ORDER BY rating DESC ) AS row_number FROM stats_userstats ) sub WHERE stats_userstats.id = sub.id; I'm using Django, and it'd be fun to learn how to express this query using the Django ORM, if possible, before resorting to running a raw query. It seems like Django has all the parts that are necessary to express the query, including the ability to use PostgreSQL's row_number() windowing function, but my current attempt updates all rows ranking with 1: from django.db.models import F, OuterRef, Subquery from django.db.models.expressions import Window from … -

Django: celery showing different status for the same task
I've a django app with two celery tasks, say task1 and task2. task1 gets triggered on a POST request from the frontend and the request has to sent back the task id so the frontend can poll its status later. task2 is supposed to run after task1 succeeds, asynchronously. Here're my task definitions: @shared_task(ignore_result=False) def task1(pk: int): # retrieve object matching pk return task1_func(obj) @shared_task(ignore_result=False) def task2(task_id: int): task = AsyncResult(task_id) while not task.ready(): logger.info("status {}".format(task.status)) time.sleep(1) return task2_func() Here's how I'm triggering them inside my views.py: class MyView(viewsets.ModelViewSet): def create(self, request): # create object task = task1.delay(obj.pk) task2.delay(task.id) #breakpoint return Response(task.id, status=status.HTTP_200_OK) Now when I try checking the status at the breakpoint, it shows success: In [1]: task.id Out[1]: '97f8d150-de04-4848-a400-3882988c833c' In [2]: task.status Out[2]: 'SUCCESS' In [3]: AsyncResult(task.id).status Out[3]: 'SUCCESS' But the code inside the task2 never gets executed because the status of task1 inside task2, never changes from PENDING. What am I doing wrong? Clearly my results are being stored and accessible but for some reason I cannot see the change in status from within another task. I cannot chain the tasks because I've to send the first task's id to the frontend. -
How exactly should JWT-based authentication be implemented in Django (drf and simplejwt)?
I am struggling to understand exactly how JWT-based authentication should be implemented in Django (I am using simplejwt). I am just a beginner, so please brace yourselves for some silly questions. The rest-framework-simplejwt documentation is very minimal and does not provide enough detail for a newbie like me. path('token/obtain', jwt_views.TokenObtainPairView.as_view(), name='token_create'), path('token/refresh', jwt_views.TokenRefreshView.as_view(), name='token_refresh'), So, I've created the paths in my urls.py as suggested by the official documentation. Where do I go from here? I guess my confusion comes from the fact that I am not sure where exactly in the code I have to issue my tokens. Let's say, I am logging in the user. So, in order to obtain the token, do I have to send a request to the 'token_create' endpoint from inside my view? Or do I have to somehow indicate it in one of my serializers? What about the 'refresh_token' endpoint? Is there a specific method that I need to use? Then, what do I do with the token once it has been issued? Clearly, I shouldn't save it in the database since it defeats the entire purpose of using JWTs in the first place. From my understanding, I should attach it to the headers … -

Pycharm Django remote execution trying to use local path
I created a Django project in Pycharm, and configured for remote execution. Pycharm happily uploads the local project to the remote VM. However, when I try to debug/execute manage.py, or another "hello world" kind of Python script, it appears that the remote python is being handed the path to manage.py, etc. on my local machine, not the path to manage.py, etc. on the remote machine.

How can I implement AJAX live search in my Django Application?
I am looking to create a recipe app with a live search feature where you will type into the search bar located at the top of the home page, and it should filter down the list of recipes that are displayed underneath (located in the partial_home.html file). What I am expecting to see is that when I input any character or string of characters, the search icon should start blinking, and then after a short delay (about 700 miliseconds), the recipes should fade out and the fade in with a filtered list. Currently I am able to have the search icon blink when inputting text into the search bar, indicating that the js file is being read, however no changes are made to the recipes and nothing is fading in/out. If I add in the following tail ".../?q="chicken" for example, I am able to load the page with filtered recipes for all recipes with "chicken" in the title, however it is not occurring asynchronously. Would anyone know what the issue is in my code? I am currently using Django 3.1.2 main.html {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Home</title> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" … -
CSRF cookie not set: POST from Javascript to separate Django project
I'm developing two separate django (version 3.1) projects. I keep getting a "403: CSRF cookie not set" error and have no idea what the problem is. Project 1 is running on an Apache server & takes POST requests containing JSON data & sends back a JSON response. Project 2, running on localhost, sends the POST via Javascript XMLHttpRequest() function to Project 1. This question seems to be having the same problem as me, but I'm trying to send info between different URL's (more specifically, POST from localhost:8000, eventually url.com, to engine.url.com) and I don't think that user's solution will work for me. I've tried using the @csrf_exempt decorator on Project 1 views.py, and it works just fine. However, personally identifying information might be sent between the two, so I want to make sure things are secure. A csrf cookie is best practice if I'm not mistaken, so I have the decorator @ensure_csrf_cookie before my view. I've tried everything I could find online to fix the problem. In Project 1 settings.py, I've included 'corsheaders' in my INSTALLED_APPS, 'django.middleware.csrf.CsrfViewMiddleware' in MIDDLEWARE and have the following code at the end of the file: CSRF_COOKIE_SECURE = False SESSION_COOKIE_SECURE = False CSRF_COOKIE_HTTPONLY = False CORS_ALLOWED_ORIGINS …
