Long running Django Celery task close DB connection
I have a Django Celery task that performs long-running operations and sometimes loses connection to the database (Postgres). the task looks like something like this: @app.task(name='my_name_of_the_task') def my_long_running_task(params): with transaction.atomic(): object_list = self.get_object_list_from_params(params) for batch in batches(object_list): self.some_calculations() MyObject.objects.bulk_create(objs=batch) # <- here connection could be lost I want to ensure the connection (but also be able to unit test this code). For example: @app.task(name='my_name_of_the_task') def my_long_running_task(params): with transaction.atomic(): object_list = self.get_object_list_from_params(params) for batch in batches(object_list): connection.connect() self.some_calculations() MyObject.objects.bulk_create(objs=batch) # <- here connection could be lost This would work (because it always opens new connections) but the unit test throws the error that can't roll back on teardown. I am thinking about @app.task(name='my_name_of_the_task') def my_long_running_task(params): with transaction.atomic(): object_list = self.get_object_list_from_params(params) for batch in batches(object_list): try: self.some_calculations() MyObject.objects.bulk_create(objs=batch) # <- here connection could be lost except Exception e: connection.connect() MyObject.objects.bulk_create(objs=batch) # retry this insert but is there a better way to handle this? -
Does nest js provide anything that runs after saving, updating or deleting, like how django signals provides?
I am running a project with nest js and prisma orm. Suppose I am creating a post record like following: // Query the database to create post ------------------------------------------------------- try { post = await this.prisma.post.create({ data: { uuid: uuidv4(), author: createPostDto.author, categoryId: postCategory.id, title: createPostDto.title, content: createPostDto.content, createdAt: new Date(), updatedAt: new Date(), } }) } catch (err) { this.logger.error(err); throw new InternalServerErrorException("Failed to create the post"); } After creating a record I want to run some perticular code. suppose I want to send notification to admins by calling sendNotification() method. But I don't want to call this method from inside an api. I know that django signals provide similar feature that can be used to run some part of code after creating, updating, or deleting a row. But I don't know what should be aprropeiate in the case of nest js. -
Django program gets stuck on get request, needs to be interrupted with Ctrl C to continue
I have tried everything I can possibly think of but I don't know what the solution is. I have a django application which running on my local network and receives requests from a react app. When the page loads tables (around 10 requests) the server seems to work quite well but randomly gets hung. When it gets hung it doesn't reach the view (the print statement doesnt run: def f(request): start_time = time.time() print('Received GET request')) and the moment I interrupt it a backlog of get requests like: Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> Received GET request <WSGIRequest: GET '/api> which print in one go and then all the remaing requests are filled. Sometimes the requests with large responses crash, but sometimes even '/' hangs which only returns a hello world for me to test the server I am using a conda environment with some: asgiref 3.7.2 pyhd8ed1ab_0 conda-forge django 4.2.7 pyhd8ed1ab_0 conda-forge django-cors-headers 4.3.1 pyhd8ed1ab_0 conda-forge django-silk 5.0.4 pyhd8ed1ab_0 conda-forge djangorestframework 3.14.0 pyhd8ed1ab_0 conda-forge memory_profiler 0.58.0 pyhd3eb1b0_0 numexpr 2.8.7 py310h2cd9be0_0 pip 23.3.1 py310haa95532_0 pyodbc 4.0.39 py310hd77b12b_0 python 3.10.13 he1021f5_0 sqlite 3.41.2 … -

Where to pass context data in Response (Django)
I am wondering how to pass some context data to response in Django. I have this endpoint: /api/facebook/user/ which returns data like this: HTTP 200 OK Allow: GET, POST, HEAD, OPTIONS Content-Type: application/json Vary: Accept [ { "facebook_account_id": "176890406129409", "first_name": "Ivan", "last_name": "K", "token_status": "active", "facebook_access_token": 1 }, { "facebook_account_id": "123123123", "first_name": "Ivan", "last_name": "FFFF", "token_status": null, "facebook_access_token": null }, { "facebook_account_id": "123123", "first_name": "Test", "last_name": "test", "token_status": null, "facebook_access_token": null } ] Here is my list serializer: class FacebookUserListSerializer(ModelSerializer): token_status = SerializerMethodField() class Meta: model = FacebookUser fields = ["facebook_account_id", "first_name", "last_name", "token_status", "facebook_access_token"] def get_token_status(self, obj): try: facebook_token = obj.facebook_access_token if facebook_token: return "active" if facebook_token.is_active else "inactive" except FacebookToken.DoesNotExist: return None Here is my list view: def list(self, request, *args, **kwargs): response = super().list(request, *args, **kwargs) data = response.data inactive_accounts = sum(1 for account in data if account.get("token_status") == "inactive") accounts_without_token = sum(1 for account in data if account.get("token_status") is None) context = {"inactive_accounts": inactive_accounts, "accounts_without_token": accounts_without_token} # Is this the correct way of passing context data to a response? response.context_data = context return response In list view, in the "context" variable, I am attempting to pass data to the frontend, but I am sure that I … -
Handling concurrent connections
I thought of implementing a game lobby (similar to chess.com). A player randomly paired with another player . I implemented this with a queue . When a new Request arrives , it checks queue and pairs to front element if any player exists in queue . Later I realized that this fails in real world as concurrent requests try to connect with same front element leading to various problems . My question is How real world game lobbies handle this problem ? Is there a way to Handle concurrent connections ? Any help is appreciated :) -

Display Django Form Fields depending on option selected using Javascript
I am working on a Django Project and I have the following html page which renders a form. I do not know much of Javascript, and I think I am going wrong somewhere in the Javascript Function or something else entirely. What I need to do is render the "id_mapnubparam01" field only when value of "id_mapnubfunction" is 'GETDATA'. I've split the if condition into 2 just to be clear, the first if condition for the "p" tag works perfectly fine. However using the same if then else logic the "id_mapnubparam01" does not do anything. Any help is appreciated. Thanks. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Data</title> </head> <body> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} {% for field in form %} <div class="fieldWrapper"> <label>{{ field.label_tag }}</label> {{ field }} </div> {% endfor %} <input type="submit" value="Submit"> </form> <p id="demo"></p> <script> function myFunction() { var x = document.getElementById("id_mapnubfunction").value; if (x != 'GETDATA') {document.getElementById("demo").innerHTML = ""; } else {document.getElementById("demo").innerHTML = "You selected: " + x; } if (x != 'GETDATA') {document.getElementById('id_mapnubparam01').hide(); } else {document.getElementById('id_mapnubparam01').show(); } } </script> </body> </html> -

Is it possible to have a conditional statement distinguish which model a Python variable is coming from? [duplicate]

Django Migration Error with PostGIS: 'double free or corruption (out) Aborted (core dumped)
I am developing a web application using Django and encountering a critical issue during database migration with PostGIS. While migrations work seamlessly with the SpatiaLite engine, switching to the PostGIS engine leads to a crash. The error message I receive is: "double free or corruption (out) Aborted (core dumped)". This issue arises specifically when I attempt to make migrations with the PostGIS engine. My Django project settings for the database are as follows: DATABASES = { 'default': { 'ENGINE': 'django.contrib.gis.db.backends.postgis', 'NAME': 'geodesia_interoperable', 'USER': 'depiction', 'PASSWORD': '************', 'HOST': 'localhost', 'PORT': '5432', } } I have verified that PostgreSQL and PostGIS are correctly installed and configured, and the database credentials are accurate. The application runs as expected with SpatiaLite but fails when switched to PostGIS. Has anyone encountered a similar issue, or does anyone have insights into what might be causing this error with PostGIS in Django? Any suggestions for troubleshooting or resolving this problem would be greatly appreciated. -

Django floatformat: no unnecessary zeros
Django's floatformat filter has a few options for formatting decimals. However, none of them work for what I consider the "standard" way to represent decimals in non-programming fields, like math or science. Specifically, I'd like decimals to be displayed with "as many decimal places as needed", up to a defined limit. Here are some examples with a limit of 3: The decimal What I want floatformat floatformat:3 floatformat:"-3" 15.000000 15 15 ✅ 15.000 ❌ 15 ✅ 15.666667 15.667 15.7 ❌ 15.667 ✅ 15.667 ✅ 15.550000 15.55 15.6 ❌ 15.550 ❌ 15.550 ❌ 15.500000 15.5 15.5 ✅ 15.500 ❌ 15.500 ❌ Tests passed: 2/4 1/4 2/4 The closest filter for my goal is probably {{ thing | floatformat:"-3" }}, and that's what I'm using right now.
