Why does my Django ORM query with naive datetimes return the same results as a PostgreSQL query with time zone-aware datetimes?
I'm using Django to filter reservations based on a date range with naive datetimes. My Django ORM query is: start_d_date_naive = "2024-11-3 00:00" end_d_date_naive = "2024-11-3 23:59" reserve_naive = Reservations.objects.filter( updated_at__range=(start_d_date_naive, end_d_date_naive), status="canceled" ) This translates to the following SQL query: SELECT * FROM "consultant_reservations" WHERE "consultant_reservations"."status" = 'canceled' AND "consultant_reservations"."updated_at" BETWEEN '2024-11-03 00:00:00' AND '2024-11-03 23:59:00' However, the results are the same as if I had run this query directly in PostgreSQL: SELECT * FROM "consultant_reservations" WHERE updated_at BETWEEN '2024-11-03 00:00:00+03:30' AND '2024-11-03 23:59:00+03:30' AND status='canceled'; Why does the Django ORM query with naive datetimes return the same results as the PostgreSQL query with time zone-aware datetimes? -

Adding a JSON index to MYSQL may result in empty query results
After I added an index to the json field in the database, some of Django's queries stopped working, so I looked into the underlying SQL and found something strange. You can reproduce the problem with the following SQL. CREATE TABLE `products` ( `id` bigint NOT NULL AUTO_INCREMENT, `status` varchar(32) DEFAULT NULL, `info` json DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin; ALTER TABLE products ADD INDEX tag_group_idx (( CAST(info->>'$."Group"' as CHAR(32)) COLLATE utf8mb4_bin )) USING BTREE; INSERT INTO products (status, info) VALUES('active', '{"Group": "G0001"}'); MySQL version: 8.0.29. OS: Windows Generated by Django SQL: SELECT * FROM products WHERE status = 'active' AND JSON_EXTRACT(info,'$."Group"') = JSON_EXTRACT('"G0001"', '$'); Result: id|status|info| --+------+----+ Using plain string SQL: SELECT * FROM products WHERE status = 'active' AND JSON_EXTRACT(info,'$."Group"') = 'G0001'; Result: id|status|info | --+------+------------------+ 1|active|{"Group": "G0001"}| Remove redundant query conditions SQL: SELECT * FROM products WHERE JSON_EXTRACT(info,'$."Group"') = JSON_EXTRACT('"G0001"', '$'); Result: id|status|info | --+------+------------------+ 1|active|{"Group": "G0001"}| As shown above, I tried three ways to query, but only the first one had empty results. I guess it was caused by the mismatch of the generated column types. I found that after I deleted the index, the first statement worked fine. ALTER TABLE products DROP … -

Django Server ignores file changes with --reload in docker
TL;DR How to make django respond to changes I make in my code? I will post the way I run my server in docker. A base dockerfile for production Another one for dev that uses it the base The entrypoint runs the django server with --reload Observations When serving a working server, any change in any file (namely urls.py and views.py) is ignored. Adding syntax errors or any change is not reflected. When serving a server with syntax errors in urls.py for example, and when the server is still running removing the syntax error, the change does work, but any subsequent changes don't work. I checked that the files do change inside the docker container, and still Django ignores them. Here is the relevant code: Dockerfile (the base) # Use Python 3.11.3 as the base image FROM python:3.11.3-slim # Set environment variables ENV PYTHONDONTWRITEBYTECODE=1 ENV PYTHONUNBUFFERED=1 ENV DJANGO_SETTINGS_MODULE=config.settings # Set work directory WORKDIR /app # Install system dependencies and debugging tools RUN apt-get update && apt-get install -y --no-install-recommends \ build-essential \ curl \ netcat-openbsd \ && rm -rf /var/lib/apt/lists/* # Install Python dependencies COPY requirements.txt /app/ RUN pip install --upgrade pip && \ pip install --no-cache-dir -r requirements.txt # … -
Django caching issue when deployed to the DigitalOcean App Platform
I followed the How To Deploy a Django App on App Platform guide from DigitalOcean and successfully created a Django server which I'm using through /admin pages. Through the App Platform, I use GitHub to push changes to production. I'm having an issue with CSS and JS files that don't update after I push changes: I've tried hard refreshing my browser, using a different browser, deleting browser caches, and nothing seems to work, the files don't update. Using the Console, I can see that the files are updated on the server (including under staticfiles), but they don't update in the browser. I read up on the STORAGES setting and the ManifestStaticFilesStorage class, so I tried adding the following setting as a means of cache busting: STORAGES = { 'staticfiles': { 'BACKEND': 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage', }, 'default': { 'BACKEND': 'django.core.files.storage.FileSystemStorage', }, } When I deploy this to production, everything seems to crash except the page I'm currently on (with the JS/CSS I've been testing). I tried deploying with DEBUG=True, but this affects the execution of the static tag by changing whether Django looks for files with their regular or hashed name, so it doesn't reproduce the errors. I'm stumped, how do I even … -

Migrations in wrong order while setting up google sign in using oauth for my django app
I am working on a web app in django and I'm trying to setup Oauth for google sign in, my project is currently pretty much empty. I tried following a tutorial on how to set this up. Upon following the tutorial step by step I encountered multiple errors which i fixed easily (for example missing middleware setup in settings.py), but now I have encountered one I can't seem to fix. I am using PostgreSQL and when running makemigrations i always get this error: django.db.migrations.exceptions.InconsistentMigrationHistory: Migration socialaccount.0002_token_max_lengths is applied before its dependency socialaccount.0001_initial on database 'default'. I tried faking the migrations using a tutorial provided by chatgpt and rerunning them somehow, but nothing seems to work. For the lack of a better tutorial and a lack of programming knowledge I find myself completely lost and unable to move forward. Can anyone help? -
React Query Not Returning Followings from Django API
I'm developing a React application that retrieves a user's followings from my Django backend API. However, I'm facing issues where the followings data is not being returned correctly. API Response When I make a GET request to the endpoint http://127.0.0.1:8000/api/chat/landing/, I receive a JSON response structured like this: { "current_followings": [ { "id": 1, "username": "Amir", "email": "Amir@amir.ir", "full_name": "amirali", "profile_photo": "/media/profile_photo/1000_F_244376003_1smlBNfWYSInMDUFymPuCcms6d1mOqaF_oU9kIP0.jpg", "banner_photo": "/media/banner_photo/header.jpg", "phone": null, "address": "", "bio": "", "profile_views": 1 } ], ... } The response includes an array of current_followings, each containing various fields like id, username, full_name, and profile_photo.

How to create a POST endpoint in Django with Tastypie
I'm learning Django and I watched and finished a tutorial (Mosh Hamedani and I purchased his videos) that created a database API GET method. I was curios how can I create a POST endpoint to add some new data. In the tutorial, he used tastypie module, if matters. In the tastypie's documents, I see it says how to add authorization, but it does not say anything about the POST. Please help me what's needed to add to and edit the question.

Using Django JSONField Like a NoSQL Database for a Quiz Application
I'm developing a Django-based quiz website and would like to use a JSONField in the Quiz model to store questions in a manner similar to NoSQL databases like MongoDB. My plan is to store questions as JSON data directly in the Quiz model (e.g., questions=models.JSONField()). While this simplifies the structure and avoids joins, I'm concerned about how it will perform regarding querying and filtering capabilities. Given this approach, what are the pros and cons of using JSONField for a large dataset in Django? How can I optimize performance and scalability? Any advice or best practices for managing such a structure would be greatly appreciated. Thank you! -

Django admin inline performing too many queries when having additional ForeignKey
I have the following Django models: from django.db import models from django.utils.translation import gettext_lazy as _ class Enterprise(models.Model): nome = models.CharField(max_length=255) class MediaTopic(models.Model): name = models.CharField(max_length=255) class EnterpriseRelatedMedia(models.Model): enterprise = models.ForeignKey( Enterprise, on_delete=models.SET_NULL, null=True, blank=True, related_name="related_medias", related_query_name="related_media", ) topic = models.ForeignKey( MediaTopic, on_delete=models.DO_NOTHING, related_name="enterprise_related_medias", related_query_name="enterprise_related_media", blank=True, null=True, ) And this is my admin.py: from django.contrib import admin from . import models class EnterpriseRelatedMediaInline(admin.StackedInline): model = models.EnterpriseRelatedMedia extra = 1 @admin.register(models.Enterprise) class EnterpriseAdmin(admin.ModelAdmin): inlines = [ EnterpriseRelatedMediaInline, ] admin.site.register(models.MediaTopic) The problem is that since my inline contains not only the enterprise foreignkey but also an extra foreignkey pointing to MediaTopic, everytime my django admin change page loads, it makes a lot of queries to the database. Im aware that this is the famous N+1 problem, and that a select_related or prefetch_related would solve it, the problem is that i do not know where to put it, i tried putting it in the EnterpriseAdmin class as well as the EnterpriseRelatedMediaInline class, and it doesn't seem to work! Every time the admin loads the page, for each instance of the inline (which are 10), it makes a query to pull all the instances of MediaTopic to be available in the foreignkey attribute of … -

How to handle file upload of a certain type and size? (Looking for Best Practices / Convention)
I have the following column definition in my Django model media = models.FileField() I want to ensure that only video files (preferably in MP4 format) can be uploaded. Additionally, is it possible to set a maximum file size, like 200 MB? Would this approach create extra load on the server, since it would need to validate the MIME type and check that the file size doesn’t exceed the limit? I know client-side checks aren’t secure on their own since they can be bypassed, but does the csrf_token help address this on the backend? -

Here is my code: <body> <nav class="navbar navbar-expand-lg navbar-dark fixed-top"> <a href="{% url 'home' %}" class="navbar-brand"> Inventory App </a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarNav"> <ul class="navbar-nav"> <li class="nav-item"> <a href="{% url 'product_create' %}" class="nav-link"> Add Product </a> </li> <li class="nav-item"> <a href="{% url 'product_list' %}" class="nav-link"> Show Products </a> </li> </ul> </div> </nav> <div class="container"> {% block content %} {% endblock %} </div> <script src="https://code.jquery.com/jquery-3.7.1.slim.min.js" integrity="sha256- kmHvs0B+OpCW5GVHUNjv9rOmY0IvSIRcf7zGUDTDQM8=" crossorigin="anonymous"></script> <script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.2/dist/js/bootstrap.min.js"></script> I have tried using defer, I used the full jquery rather than slim, made sure jquery is before bootstrap, I changed data-toggle to data-bs-toggle also with target, I tried putting everything in a div container and all that did was change the positioning. I have yet to see the nav toggle button even appear on the website yet. -

Cronjob in Docker container uses outdated settings in Django, despite environment variables in Docker Compose
I'm facing a persistent issue with a Django app using Django REST Framework. The application has several models, including one called Project with a created_at timestamp. There’s a management command in manage.py that archives a project if a user hasn't taken action on it within 72 hours of its creation. This command is executed by a cronjob in production, and the entire setup runs within a Docker container. Initial Setup In the past, I separated the back-end environment into two Docker containers: One container ran the Django application and served the API. The other container was dedicated solely to running the cronjob that executed these management commands. Reason for Combining Containers This setup had the same issue with outdated settings, and managing both containers separately added significant overhead, as I needed to clear both containers’ caches and rebuild them frequently. To simplify, I combined the API and cronjob into a single container and used Supervisor to manage the cronjob within this container. Note that Supervisor is functioning correctly, as the cronjob itself runs on schedule (logs confirm this), but it’s only an environment variable issue within the cronjob. The Problem The cronjob uses outdated settings—specifically an old DB_HOST that points …
