Error reversing django migrations with sql_safe_update mode set in MariaDB
I am running into issues when I try to reverse migrate one of the migrations in Django due to sql_safe_update mode is set in MariaDB. The exact sql statement it runs for reverse is: ALTER TABLE `user` DROP COLUMN `pin_code`; And the error that I get from django is: MySQLdb.OperationalError: (1175, 'You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column') Now my database is in inconsistent state because the column has been dropped and failed migration was not rolled back as MySQL DDL statements are not run in transaction. Now even with --fake it shows the same error. Is there a way to tell django to run migrations with sql_safe_update=0 only for duration of migrations? Note that I cannot turn off sql_safe_update globally as DB admins are adamant on not removing it globally. Also it is not entirely clear why DROP column requires a WHERE statement? -
Query sum with distant foreign key relations in Django
Let's say I have models like this: class Product(models.Model): ... class Item(models.Model): product = models.ForeignKey(Product, related_name="items") quantity = models.IntegerField() class Order(models.Model): item = models.ForeignKey(Item, related_name="orders") quantity = models.IntegerField() I now want to get a list of Product annotated with the field total_supply. "Total supply" is defined for each product as: (sum of all of a product's items' quantity) - (sum of quantity on all of the Order objects associated with one of the product's items.) Here is what I have tried: Product.objects.annotate(actual_supply=Sum("items__quantity") - Sum("items__orders__quantity")) I am getting unexpected results. How am I supposed to write such a query? Thank you -
How to define individual service name for each type of Opentelemetry auto instrumentation in a python application?
We are currently using Datadog for monitoring and observability in our application, and we have integrated OpenTelemetry for distributed tracing. We have encountered one main issue Span Separation: Currently, all the spans from our application are being exported to Datadog under a single service. However, we would like to separate them into different services based on the type of instrumentation used (e.g., Django, Elasticsearch, requests, etc.). Manage.py configure_opentelemetry() #Auto Instrumentation of Django, Psycopg2, Pymemcache, Elasticsearch, URLLib3, Requests DjangoInstrumentor().instrument(request_hook=fix_django_req) PymemcacheInstrumentor().instrument() RequestsInstrumentor().instrument() ElasticsearchInstrumentor().instrument() Psycopg2Instrumentor().instrument(enable_commenter=True, commenter_options={}) URLLib3Instrumentor().instrument() configure_opentelemetry method def configure_opentelemetry(): otlp_exporter = OTLPSpanExporter(endpoint=os.getenv("OTEL_COLLECTOR_URL"), insecure=True) # Set the global TracerProvider with the OTLP exporter trace.set_tracer_provider(TracerProvider(resource=Resource.create({SERVICE_NAME: os.getenv("OTEL_SERVICE_NAME"), "env": os.getenv('OTEL_ENV')}))) # Create a BatchSpanProcessor and add the exporter to it span_processor = BatchSpanProcessor(otlp_exporter) trace.get_tracer_provider().add_span_processor(span_processor) tracer = trace.get_tracer(__name__) Collector Config: receivers: otlp: protocols: grpc: http: processors: batch: # batch metrics before sending to reduce API usage send_batch_max_size: 100 send_batch_size: 10 timeout: 10s memory_limiter: # drop metrics if memory usage gets too high check_interval: 1s limit_percentage: 65 spike_limit_percentage: 20 resourcedetection: detectors: [env, gcp] timeout: 2s override: false transform: error_mode: ignore trace_statements: - context: span statements: - set(attributes["resource.name"], name) exporters: datadog: api: site: ${DD_SITE} key: ${DD_API_KEY} extensions: health_check: service: extensions: [health_check] pipelines: traces: receivers: [otlp] processors: [memory_limiter, resourcedetection, … -
Django simple ModelForm not showing on page (I'm using class based-views), what could be the problem?

OAUTH2 Django problems with client_secret
I was updating an old non documented project, database, users, etc.. Suddenly it came a problem, the client_secret_id is not hashed, if I edited in /o/applications then it become hashed. Is there a simple way to hash every client_secret_id other than manually do it one by one, application per application? I found the library, but I don't have any idea where is the salt, or how to include it -
How to get static files to work in Django | Favicon not getting loaded but appears when entering that directory
I'm having trouble trying to get my static files to work, I've already tried different answers for a long time and I'm getting confused what's the problem. I was trying to load my css with debug turned off, but I think its normal for the css not to appear since django doesn't load static files with debug turned off. My problem was when trying to put a favicon into my test website. I also think in the future I'll have complications with JS, etc.. main.html {% load static %} <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>Hello, Django</title> <!-- load staticfiles--> <link rel="stylesheet" href="{% static 'main.css' %}"> <link rel="shortcut icon" href="{% static "favicon.ico" %}}" type="image/png"> </head> <body> </body> </html> urls.py from django.urls import path from f1trackerapp import views from django.contrib.staticfiles.storage import staticfiles_storage from django.views.generic.base import RedirectView urlpatterns = [ path("", views.f1trackerapp, name="f1trackerapp"), path('favicon.ico', RedirectView.as_view(url=staticfiles_storage.url('favicon.ico'))) ] settings.py (stackoverflow doesn't let me post full settings.py code) ... from pathlib import Path import os # Build paths inside the project like this: BASE_DIR / 'subdir'.

HTML does not recognize CSS file - Django
I recently started working on my first python + django project and I'm working on some visual things, but I noticed that the HTML isn't recognizing my CSS file. I follow the documentation about How to manage static files but nothing worked. So, this is my settings.py #app definition INSTALLED_APPS = [ #personalizacao #'grappelli', #Configuraçoes principais 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles' ] #statics configs STATIC_URL = "/static/" STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), ] STATIC_ROOT = os.path.join(BASE_DIR, 'static/') STATICFILES_FINDERS = ( 'django.contrib.staticfiles.finders.FileSystemFinder', # 'django.contrib.staticfiles.finders.AppDirectoriesFinder', #causes verbose duplicate notifications in django 1.9 ) In my HTML I have {% load static %} <link rel="stylesheet" href="{% static 'css/styles.css' %}" /> And I can call the stuff that I have on the static/img folder with no problem So does anyone know what can it be? I don't know where to look anymore -
AWS EC2 Django Requests working from Public ipv4 address, but not Public ipv4 DNS address
Running a django project on an ubuntu 22.04 instance on a new account including a default VPC. Using a custom security group with 3 inbound rules: ipv6(http) on port 80, ipv4(http) on port 80, and ipv4(ssh) on port 22. Outbound rule is the same as default, ipv4(all) on all ports. No key pair was set. Running with gunicorn, nginx, and supervisor. sudo nginx -t shows no issues, supervisor err logs are empty. /var/log/nginx/access.log shows that the api is receiving requests from both sites with no difference in the logs besides codes 200 29 for the successful request from the public ipv4, and codes 404 197 for the failed request from the public ipv4 DNS. It's also worth noting that the public ipv4 DNS serves the default nginx page on the base url while the public ipv4 shows resource not found. There are no relevant errors in /var/log/nginx/error.log. -
Why is Heroku not updating my Django app's code?
I have a Django blog deployed by Heroku, statics served with S3 Bucket. A few days ago I realised that my changes are not shown in the actual code when I inspect it with Chrome's Inspector tool. I pushed them to the git repo and to heroku master. This project is for my thesis, so it would be really important to resolve this problem. Thank you very much to spend your time helping me in advance. This is one of my latest changes: Added a paragraph to a django signup form that the user can view my Privacy Policy before signing up to my blog. I attached the code from PyCharm: {% extends 'default.html' %} {% block content %} <h1>Signup</h1> <form class="site-form" action="/accounts/signup/" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Signup"> </form> <!-- Privacy Policy Link --> <p>By signing up, you agree to our <a href="https://www.termsfeed.com/live/d0e2bb42-feca-4abe-8051-afccfe402f6a">Privacy Policy</a>.</p> {% endblock %} The code from the actual website with Google's Inspector tool: <form class="site-form" action="/accounts/signup/" method="post"> <input type="hidden" name="csrfmiddlewaretoken" value="1P17fSXi3R2ihBMd17GqUPmx2pIsL4c855BnGwrhTbenlx4sKQea1nJTuCK0Apei"> <label for="id_username">Username:</label><input type="text" name="username" maxlength="150" autofocus="" required="" id="id_username" data-siid="si_input_0"><br><span class="helptext">Required. 150 characters or fewer.

AWS EC2 instance public ipv4 DNS address pointing to private ipv4 address instead of public ipv4 address
Running a django project on an ubuntu 22.04 instance on a new account including a default VPC. Using a custom security group with 3 inbound rules: ipv6(http) on port 80, ipv4(http) on port 80, and ipv4(ssh) on port 22. Outbound rule is the same as default, ipv4(all) on all ports. No key pair was set. Running with gunicorn, nginx, and supervisor. sudo nginx -t shows no issues, supervisor err logs are empty, and accessing the api through the public ipv4 address http://xx.xxx.xx.xxx works properly, serving content when requested, with the base url showing Not Found. Accessing through the private ipv4 address does not respond. The problem is that when accessing through the public ipv4 DNS address, http://ec2-xx-xxx-xx-xxx.us-east-2.compute.amazonaws.com, where the x values match the public ipv4 address, the site only serves the default nginx page. Running nslookup on the DNS address returns the private ipv4 address. Why doesn't the DNS address point to the public ipv4 address? And why does it serve content at all if it points to the private ipv4 address which doesn't respond? Here are the configurations I used for nginx: Changed nginx.conf user to root, and created/linked django.conf in /etc/nginx/sites-available and /etc/nginx/sites-enabled: `server{ listen 80; Server_name [public … -

Django cripsy form with a custom template for button
I have a need for a <button> element for my form submit instead of the layout helper Submit() input with Django and django-crispy-form. If I use {{ my_form|crispy }} I'm able to do this. However, with this method all of the other layout elements in the form are ignored. If I switch back to {% crispy my_form %} I get the layout back, but then my custom HTML button is ignored. Is there any way to have a custom HTML submit button while using the Layout helper? Note: If I add the HTML button below the crispy tag the button renders outside of the form, and I cannot iterate through the form fields in the template because my Layout in the Django form is very complex. -
React chat app messages don't have different className
I am making a chat app with django channels and react. I save the messages in state. When a new message is made I want it to have the className of the current user. The problem is that all messages have the className of the user reading them even if they were written from other. For example I am sending messages from 2 different browsers. The one is logged as first and the other as second. If first sends a message it will appear with a className of first. But for second this message will appear with a className of second chatSocket.onmessage = function(e) { if (ran == true) { const data = JSON.parse(e.data); setMessages(old => [...old, <p ref={oneRef} id={currentUser[0]?.username} className={currentUser[0]?.username}>{data.message}</p>]) } } What can I do to solve this. -
