Django - Heroku postgres connection opens with each page refresh and does not close ever
I am using Django, heroku, websocket, AJAX, celery, postgres, consumer, asgi (uvicorn; tried Daphne also). My problem is that after just a page refresh, new postgres connection would be created, and it doesn't go away even after long inactivity. Soon with just refreshes my connections go over the top (20/20 on heroku). On local environment, no problem - connection does not add up no matter what I do. This happens only on heroku using heroku postgres (I'm using the default version). What I've tried: I've checked pg_stat_activity. The connections are related to the corresponding view code that queries certain data. for post in posts: temp_dict = defaultdict(list) recommendations_ordered = post.recommendations.all().order_by('created_at') ...and so on, including request.user. If I have 15 connections, most of them are from this -- same query. One from request.user. All idle. These don't exist when I run pg_stat_activity on local postgres. I've set my database settings as: if ENVIRONMENT == 'development': DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'redacted', 'USER': 'redacted', 'PASSWORD': 'redacted', 'HOST': 'localhost', 'PORT': '5432', } } else: DATABASES = { 'default': dj_database_url.config(default=os.environ.get('DATABASE_URL')) } DATABASES['default']['CONN_MAX_AGE'] = 0 DATABASES['default']['ATOMIC_REQUESTS'] = True I've added close.connection to the aforementioned view as well as tasks. Here's my procfile. … -

How can i make many-to-many selected fields clickable as links in django admin panel
I'm working on a Django project, and I have an admin panel where I manage projects. In this project admin, I have a matched_pros field, which is a ManyToManyField related to the "main.User" model. I would like to make the selected fields in the matched_pros widget clickable, so that when I click on a user, it takes me to the user change page in the admin panel. matched_pros = models.ManyToManyField( "main.User", blank=True, related_name="matched_projects" ) exemple: many to many widget like in the picture when i click on client alger- c51 block it will take me to admin/main/pro/51/change I've attempted to add JavaScript code to make the users clickable, but I'm encountering issues with the code not functioning as expected, and i don't wanna complicate it using javascript and adding another file to the codebase -

Login form, django and react send data with post method but I cant get it in the server
I'm currently working on a web application using Django and React. I'm specifically facing an issue with handling form data. I have created a login form in my React application, and when I submit the form, I'm sending the form data to the server. However, on the server side (using Django), I'm having trouble receiving and processing the form data correctly. After submitting the form, I'm expecting to receive the form data on the server and perform some authentication logic. But when I try to access the received data on the server, I'm getting an empty dictionary instead of the expected form data. I have checked my client-side code and ensured that the form data is being sent correctly from the React application. However, I'm not sure why the server is not able to receive and process the data properly. I would greatly appreciate it if anyone could provide guidance or suggestions on how to properly handle and receive form data on the server side using Django. If you have any experience with Django and React and have encountered a similar issue before, your insights would be invaluable. Thank you in advance for any help or advice you can provide!" … -

What are best practices for implementing an admin panel?
I'm implementing an admin panel for my Django (API) & SvelteKit (frontend only) web application. What are the best practices for implementing an admin panel, security wise? I'm torn between multiple options right now: Setting up a different django project that accesses the database of my main project (kinda having trouble finding out how to apply my main projects' models and migrations to the panel though) Just adding (additional) admin panel functionality to my main django project Adding an admin panel to my SvelteKit frontend My main concern with no. 2 and 3 is that I'm not sure if it could be a security risk giving users the option to access even just the login panel to the admin interface if the application and the admin panel are both running within the same context, accessible to the user. If I'd go for the first option I'd restrict access to the django admin panel project entirely and make it only accessibly from within the intranet. Am I overthinking too much here and making a whole fuzz about nothing? What would "best practice" to safely implement an admin panel in an environment like mine? -

Lets say I have index.html page with a button and a H2 tag element. I want to update the H2 tag with the button text using django python when clicked

How to combine objects in a full outer join with Django?
Let's use Django's standard users and groups. I have a couple of users and groups and each user can be assigned to several groups via a M2M relation. Now, I want to construct a single query which cross joins users x groups. The purpose is a view that shows all groups with it's members, when users are members of several groups then I want them to be shown in each group. I currently have this query, which appears to give me a cross join: groups = list(Group.objects.all()) queryset = User.objects.filter(groups__in=groups) However, the query only contains data about the users. How can I include the data for each group into the queryset? -

Got AttributeError when attempting to get a value for field ProDetails on serializer UserSerializer. The serializer field might be named incorrectly and not match any attribute or key on the CustomUser instance. Original exception text was: CustomUser object has no attribute ProDetails.

Django doesn't show yellow page
So I have initialized a django project (v4.2.5) and every thing works fine and debug is set to True, but I never get the yellow page when errors occur, instead I always get this: A server error occurred. Please contact the administrator. I do have django.middleware.common.CommonMiddleware and DEBUG_PROPAGATE_EXCEPTIONS is set to true as well and I have to check what is the problem in terminal all the time, any idea what could be the problem? -
Why does it give an error even though I created the template filter according to the Django documentation?
from django import template register = template.library() # in here, pycharm say : 'library' is not callable @register.filter(name='LIM') def limited_index(val, arg): return val[:arg] terminal : Cannot find reference 'assignment_tag' in 'library.py'
