Hi everyone, I've been having issues with Gunicorn and Nginx — the latter is not loading my 'static' files. Please help, I've been stuck on this for a week and I don't know what's going on.

What should be the best practice for handling migration files in Django when multiple developers are involved?
I have a question regarding Django migration files and version control. When I run migration commands in Django python manage.py makemigrations and python manage.py migrate, files such as 0001_initial.py are created. I've come across differing opinions online about whether migration files should be committed to Git or added to .gitignore. Some suggest ignoring them, while others recommend committing them and squashing when necessary. Could someone explain the scenarios that arise when multiple developers commit migration files, what issues or errors might occur, and how we can avoid these problems in a collaborative environment? I am new to Django. Thanks -
post() missing 1 required positional argument: 'slug'
I'm facing a problem in my Django project, and I need your help. When I try to access the view that handles requests to the post page, I get the following error: post() missing 1 required positional argument: 'slug' This happens when I try to navigate to a URL that should handle viewing a specific post. I have determined the route in urls.py , which takes the slug parameter, and it looks like this: path('post//', post, name='post'), In my post view, I expect to accept this parameter, but it looks like it is not being passed properly. I would really appreciate any help or advice. My models.py: from django.db import models from django.utils.text import slugify from django.contrib.auth import get_user_model from django_resized import ResizedImageField from tinymce.models import HTMLField from hitcount.models import HitCountMixin, HitCount from django.contrib.contenttypes.fields import GenericRelation from taggit.managers import TaggableManager from django.shortcuts import reverse User= get_user_model() class Author(models.Model): user =models.ForeignKey(User,on_delete=models.CASCADE) fullname = models.CharField(max_length=40,blank=True) slug = slug = models.SlugField(max_length=400,unique=True,blank=True) bio = models.TextField(HTMLField) points = models.IntegerField(default=0) profile_pic = ResizedImageField(size=[50,80],quality=100,upload_to='authors',default=None,null=True,blank=True) def __str__(self): return self.fullname def save(self,*args,**kwargs): if not self.slug: self.slug = slugify(self.fullname) super(Author,self).save(*args, **kwargs) class Category(models.Model): title = models.CharField(max_length=50) slug = models.SlugField(max_length=400,unique=True,blank=True) class Meta: verbose_name_plural = 'categories' def __str__(self): return self.title def save(self,*args,**kwargs): … -
Error connect with Cloud SQL, Cloud Run and Django
I have an application running on Django in Cloud Run that connects to a PostgreSQL database hosted on Cloud SQL. It is currently working and configured as follows: DATABASES = {'default': env.db()} DATABASES['default']['OPTIONS'] = { 'pool': { 'min_size': 5, 'max_size': 20 } } This configuration works, but the active connections remain high. When I remove the pool configuration, I end up getting several errors. 2025/04/12 16:24:15 Cloud SQL connection failed. Please see https://cloud.google.com/sql/docs/mysql/connect-run for additional details: failed to get instance: Refresh error: failed to get instance metadata (connection name = "xxx"): googleapi: Error 429: Quota exceeded for quota metric 'Connect Queries' and limit 'Connect Queries per minute per user per region' of service 'sqladmin.googleapis.com' for consumer 'xxx'. Even after configuring CONN_MAX_AGE, it keeps throwing errors. I’ve tried setting up pgBouncer, but was unsuccessful due to needing permissions that are impossible to access on Cloud SQL. Lastly, I’m running Django in the following way: WEB_CONCURRENCY=${WEB_CONCURRENCY:-4} THREADS=${THREADS:-8} exec /usr/local/bin/gunicorn project.asgi:application \ --bind "0.0.0.0:$PORT" \ --workers "$WEB_CONCURRENCY" \ --worker-class uvicorn.workers.UvicornWorker \ --threads "$THREADS" \ --timeout 0 Has anyone ever faced something similar or has a solution for this? -

Infinite redirection loop for Django backend (hosted on railway) application (hosted on cloudfare)
tl;dr I'm getting an infinite loop when I request my django backend, and I don't know how to fix it I'll give some context to what's happening: My django backend works on localhost (I used nginx as a reverse proxy when developing it) I've got a cloudfare domain, and I've registered by backend to it on railway when I try to connect to the backend over the Cloudflare domain, I keep getting redirected to the page I requested- so it's an infinite loop I'll give some outputs to show what's happening Request headers: Request URL: https:... <--- my project domain Request Method: GET Status Code: 301 Moved Permanently Remote Address: x.x.x.x:443 Referrer Policy: strict-origin-when-cross-origin And the response: alt-svc: h3=":443"; ma=86400 cf-cache-status: DYNAMIC cf-ray: 92efc2dfbffc57dd-SYD content-type: text/html; charset=utf-8 date: Sat, 12 Apr 2025 03:50:44 GMT location: ... <--- same domain name as I requested nel: {"success_fraction":0,"report_to":"cf-nel","max_age":604800} report-to: {"endpoints":[{"url":"https:\/\/a.nel.cloudflare.com\/report\/v4?s=BY0YmE3vW8uxgXBlVKUb%2BBuxQrbGw%2F2J2wEGzGndoKueBiCzA%2FYkGsADUkrcMq6KC02ocvzetSIzDhSun56YdCECv04ANU3UaaxEzBQ6%2BnNfN9r5tmjhDD53DHq3IPVCnWnwPw%3D%3D"}],"group":"cf-nel","max_age":604800} server: cloudflare server-timing: cfL4;desc="?proto=QUIC&rtt=8014&min_rtt=7349&rtt_var=1550&sent=12&recv=11&lost=0&retrans=0&sent_bytes=3715&recv_bytes=3440&delivery_rate=821&cwnd=12000&unsent_bytes=0&cid=b1e2e4808802a704&ts=2802&x=16" x-railway-edge: railway/us-west2 x-railway-request-id: hd3fL70KS824dNgkcC4bnQ_3336177264 This request and response keep happening until the browser steps in.

Optimizing Django ORM for Hybrid Queries (PostgreSQL + Vector Similarity Search)
I'm implementing a RAG (Retrieval-Augmented Generation) system that requires combining traditional Django ORM filtering with vector similarity searches. The specific workflow needs to: First filter products by standard relational fields (e.g., category="books") Then perform vector similarity search on just that filtered subset of product descriptions Current Implementation and Challenges: # Current inefficient approach (two separate operations) books = Product.objects.filter(category="books") # Initial DB query vectors = get_embeddings([b.description for b in books]) # Expensive embedding generation results = faiss_search(vectors, query_embedding) # Vector search Key problems with this approach: Requires loading all filtered records into memory Makes two separate passes over the data Doesn't leverage PostgreSQL's native capabilities when using pgvector What I've Tried: Raw SQL with pgvector: query = """ SELECT id FROM products WHERE category = 'books' ORDER BY description_embedding <=> %s LIMIT 10 """ results = Product.objects.raw(query, [query_embedding]) Problem: Loses Django ORM benefits like chaining, model methods. django-pgvector extension: from pgvector.django import L2Distance books = Product.objects.annotate( distance=L2Distance('description_embedding', query_embedding) ).filter(category="books").order_by('distance')[:10] Problem: Doesn't scale well with complex filter conditions Expected Solution: Looking for a way to: Maintain Django ORM's expressiveness for initial filtering. Efficiently combine with vector search on the filtered subset. Avoid loading all records into memory. Preferably stay within Django's … -

Unable to open nginx with domain and can't open checkmk in Firefox browser
So I'm unable to open nginx with my domain name, arborhub.io and I can't open checkmk on the browser either. I decided to try & run checkmk behind nginx instead of apache, which I did successfully. I was hoping to fix the issue of the conflict between apache (checkmk) and nginx. But I still can't open either programs in my Firefox browser. I initially assumed my Django was causing this 502 gateway page error, but my Django server is running fine.

@login_required depending on setting?
While I expected this to be answered somewhere on StackOverflow, I haven't found it, so I apologise if this is a dupe. I want a setting to control whether certain views require a user to be logged in. If the setting is turned on, I want the views to behave as if they were decorated with @login_required, i.e. after the user logs in, they should be redirected back to the view. I don't mind putting code in the view to check the setting and calling redirect("account_login") if it's turned on. And, I suppose, passing request.get_full_path() as the next parameter would probably work. But redirecting to login and back seems a common enough use case for me to expect some elegant function in django.contrib.auth or django-allauth to do it, or that it would be easy to roll my own conditional @login_required decorator. Am I missing something? Thanks. -
Playwright's set_input_files() function doesn't work properly in python
I'm writing tests for my Django project using playwright and StaticLiveServerTestCase. In one test I need to choose two files using input[type=file] field and send them to the server. file_input = page.locator('input[type="file"]') file_input.set_input_files(["Input1.xlsx", "Input2.xlsx"]) But Playwright sending only first file and my test fails. I've tried to watch does input field has only one file, but it has both of them inside after choosing file_info = page.evaluate(""" element => { const files = Array.from(element.files); return files.map(file => ({ name: file.name, size: file.size, type: file.type })); } """, file_input.element_handle()) print("Files that JS sees:", file_info) That is the output: Files that JS sees: [{'name': 'Input1.xlsx', 'size': 5853, 'type': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'}, {'name': 'Input2.xlsx', 'size': 5851, 'type': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'}] And Playwright outs only the first: input_value = file_input.input_value() print("Playwright's version:", input_value) Playwright's version: C:\fakepath\Input1.xlsx If you'll ask me I've tried absolute path for files and I've tried to change browsers.

What is best way to store small amount of data in BE (literally 1 line)?
I am currently working on functionality where users wants to keep a single message in header of a page to notify others of something happening in system. Essentially a header that can be updated by any user. As this header needs to be shown to every user in site I can't store it in local storage or user's table. Also this is a single line of message on a single page, so making a whole database table for this sounds utterly stupid. So to achieve this functionality for now I have added a json file in BE which just have this message in there and a view which allows users to edit this file. I have also placed this file in gitignore because data change in this should not reflect in git. This system works fine for now, but when I redeploy using Docker this file is removed and rebuilt losing the initial message. Is there a better way to store and update this data? Or any way to not lose my data on redeploy? userdata.json { message: "Holiday tomorrow, please report any issues by 3." } Reading data in Django View try: if not os.path.exists(USERDATA_FILE): # Create the file … -
Can't establish connection between web socket and server

Here is my code: #UTC to "America/Winnipeg" utc1 = datetime.datetime(2025,4,8,12,00) utc1 = utc1.replace(tzinfo = pytz.utc) utc2wpg = utc1.astimezone(pytz.timezone("America/Winnipeg")) wpgb2utc = utc2wpg.astimezone(pytz.utc) print(f"UTC Time: {utc1}") print(f"UTC to Winnipeg Time: {utc2wpg}") print(f"Winnipeg back to UTC Time: {wpgb2utc}") #America/Winnipeg to UTC wpg1 = datetime.datetime(2025,4,8,7,0) wpg1 = wpg1.replace(tzinfo = pytz.timezone("America/Winnipeg")) wpg2utc = wpg1.astimezone(pytz.utc) utcb2wpg = wpg2utc.astimezone(pytz.timezone("America/Winnipeg")) print(f"Winnipeg Time: {wpg1}") print(f"Winnipeg to UTC Time: {wpg2utc}") print(f"UTC back to Winnipeg Time: {utcb2wpg}") When you run the UTC to "America/Winnipeg" block, you get the output: UTC Time: 2025-04-08 12:00:00+00:00 UTC to Winnipeg Time: 2025-04-08 07:00:00-05:00 Winnipeg back to UTC Time: 2025-04-08 12:00:00+00:00 But when you run the exact same timezone converting back from Winnipeg to UTC, you get this output: Winnipeg Time: 2025-04-08 07:00:00-06:29 Winnipeg to UTC Time: 2025-04-08 13:29:00+00:00 UTC back to Winnipeg Time: 2025-04-08 08:29:00-05:00 There is clearly a discrepancy in the timezone conversions. Is there an issue with my code or is there an issue with the pytz library's conversion. Are you having the same output? Btw I am using Python 3.13 -

Django with a single db raises "the current database router prevents this relation" when intializing model
In django I have the following database models: ParentA ParentB Connector which has a foreign key that references the model ParentA and a foreign key that references the model ParentB The Connector model: from django.db import models class Connector(models.Model): class Meta: ordering = ["parent_a"] unique_together = (("parent_a", "parent_b"),) parent_a = models.ForeignKey( ParentA, on_delete=models.CASCADE, related_name="connected_bs", ) parent_b = models.ForeignKey( ParentB, on_delete=models.CASCADE, related_name="connected_as", ) In my code each time a ParentA objects gets created I am finding which existing ParentB objects can get connected with it and I am creating Connector objects with the code that follows. The function that creates the Connector objects is a method of the ParentA, so self here is a ParentA object from django.db import models class ParentA(models.Model): ... def create_connectors(self): matching_p_b_objects = self.__get_matching_parent_b_objects() new_matching_p_b_objects = matching_p_b_objects.filter(~Q(connected_as__parent_a=self)) Connector.objects.bulk_create( [ Connector(parent_a=self, parent_b=parent_b) for parent_b in new_matching_p_b_objects ] ) The function is called all the time and it mostly works but some times it randomly throws the error File "/code/backend/app/models/parent_a.py", line 989, in create_connectors [ File "/code/backend/app/models/parent_a.py", line 990, in <listcomp> Connector(parent_a=self, parent_b=parent_b) File "/usr/local/lib/python3.10/site-packages/django/db/models/base.py", line 541, in __init__ _setattr(self, field.name, rel_obj) File "/usr/local/lib/python3.10/site-packages/django/db/models/fields/related_descriptors.py", line 254, in __set__ raise ValueError( ValueError: Cannot assign "<ParentA: 340459>": the current database router …
