How "unpythonic" is it for an exception to be the expected outcome?
In Django I am validating a request which submits something that a user is only supposed to submit once, and in the "correct behavour sequence" an Exception is raised: try: my_row = models.MyModel.objects.get(id=instance_id, user=request.logged_in_user) return HttpResponseBadRequest("Already submitted") except models.MyModel.DoesNotExist: pass // continue Scale of 1-10, how much of a crime is this? -
Unclear error in Django rest framework swagger - guid instead of uuid
I have a Django rest framework project that is documented using drf-spectacular. In one of the endpoints I use rest_framework.serializer.UUIDField inside a serializer which inherit from rest_framework.serializer.serializer. But once I assign a wrong value in the swagger page the error is "Value must be a Guid". Why Guid and not UUID? Can I change it somehow? I don't understand from where it is coming from, did someone can assist with it? Search the "drf-spectacular" repo and didn't find it. -
Django Testing: Use main database as only one database available?
I am a university student, and I decided to use Django for my final year project. This means I am limited to using the University's MySQL database server. On the server, I am only allowed to have one database under my name and do not have permission to create any more of my own. I cannot use Django's test database functionality, as I only have one available and cannot create another. So, when I run ./manage.py test, I get the error... Found 3 test(s). Creating test database for alias 'default'... Got an error creating the test database: (1044, "Access denied for user 'comp24394'@'%' to database 'test_comp24394'") How can I get around this? Is it possible for "test" tables to be created in the main database? Or, can I have the test database on another server from the main - if so, what would be the steps to implement this? Thank you for any help! -
Which method is best for designing custom error pages in Django?
For example, I've seen methods which design custom views with changes to URLconf, I've seen other methods that use handler404 = "mysite.views.my_custom_page_not_found_view" in URLconf with no changes to views. I've seen both of these methods explained in the docs. The easiest method I've seen is to simply create a templates/404.html without any other changes to the app. So which method is best for a production app? -
Select TruncYear start with specific year
I have Transactions stored in a Table, to select the last 3 years I wrote a simple Query in Django. I did this mid last year and it seemed to be fine. Now it would be nice if it would return me the year 2025 with 0, how could I achive that? Current Query: Transactions.objects .annotate(year=TruncYear('timestamp')) .values('year') .order_by('-year') .annotate(total=Sum('amount')) .values('year', 'total')[:3] This returns me the data for the years 2024,2023,2022 which is okay, but it would look more nice if it would return the data for 2025,2024,2023 Something like a change to get the current year and browse the table from there on. regardless of the table transactions having data for this year or not. -
How to Remove or Skip Object Serialization in Django Rest Framework Based on Conditions?

Adding custom actions button to wagtail snippets
I have been trying to look through the documentation on how to add custom action buttons for wagtail snippets. No luck so far.

I need to add a custom action button just for this snippet to run some custom logic. Appreciate if anyone can point me to right direction. -
When referencing imported Django model, I get 'local variable referenced before assignment' error
I am trying to import a model into my Django view and then query all objects, sort them, and iterate over them. I am not getting any error when importing the model, however, when trying to query the model with songs = song.objects.all()#.order_by('-release_date'), I am getting an error: UnboundLocalError at /hotline/dbm local variable 'song' referenced before assignment /home/path/to/site/views.py, line 82, in dbm songs = song.objects.all()#.order_by('-release_date') I do not understand what the problem is, as the variable song is clearly imported from my models.py file, and I am not getting any errors importing it - so why is Python not recognizing song as what I imported from my models.py file?

How to create GeneratedField with lookup from settings file?
While using Django 5.1, I'm trying to create a GeneratedField which should return True or False depending on which file has been uploaded. The model will accept both image- and video files.

Django's select_for_update(skip_locked=True) not compatible with spanning
I was attempting to lock the oldest item in a queryset and bashed my head over why it was not working. Every time I used this first code snippet the entire query set would be locked. with transaction.atomic(): locked_entry = Entry.objects.select_for_update(skip_locked=True).filter( event__date=distribution_date(), status='pending', entry_type__name='Premium' ).order_by('-created_at').first() print(locked_entry) sleep(4) However, upon passing the exact FK instances the lock began to correctly only lock the oldest instance. I'm sure it has something to do with how the SQL is called but was hoping for an explanation if there are any Django experts out there :) with transaction.atomic(): locked_entry = Entry.objects.select_for_update(skip_locked=True).filter( event=Event.objects.get(date=distribution_date()), status='pending', entry_type=EntryType.objects.get(name='Premium') ).order_by('-created_at').first() print(locked_entry) sleep(4) -

Django model foreign key to whichever model calls it
I am getting back into Django after a few years, and am running into the following problem. I am making a system where there are 2 models; a survey, and an update. I want to make a notification model that would automatically have an object added when I add a survey object or update object, and the notification object would have a foreign key to the model object which caused it to be added. However I am running into a brick wall figuring out how I would do this, to have a model with a foreign key which can be to one of two models, which would be automatically set to the model object which creates it. Any help with this would be appreciated. I am trying to make a model that looks something like this (psuedocode): class notification(models.model): source = models.ForeignKey(to model that created it) #this is what I need help with start_date = models.DateTimeField(inherited from model that created it) end_date = models.DateTimeField(inherited from model that created it) Also, just to add some context to the question and in case I am looking at this from the wrong angle, I am wanting to do this because both surveys and … -

Django ManyToMany through model/table indexing
For ManyToMany relationships Django will automatically create a trough model/table. For example for: class Magazine(models.Model): pass class Article(models.Model): magazines = models.ManyToManyField('Magazine', related_name='articles') there will be a Article.through manager and model. The associated table will have two separate indices for each of the columns. Two questions: How do I create a new index on both columns? I could run a raw SQL query to do it, but I wonder if there is a way to do something similar to how index_together, which is easy to maintain and track. Is there a reason why Django doesn't automatically add an index to both columns? In my test, I manually created the index and saw Postgres hit it a lot and gain performance. -

When I look at the developer tools, I don’t see my Javascript and HTML files being passed to the browser.

When I enter in the URL for the static files such as domain/static/styles.css or domain/static/index.js, I get sent to the file and no issue occurs. It’s just for some reason when I enter the page that the static files should be included on, browser doesn’t make a request for the static files. -

Best Practice for Creating a Model's Record in `post_save` Signal While Maintaining Data Integrity in Django
I am working on a Django application where I need to automatically create a Setting record with default values whenever a new User is created. My current implementation uses the post_save signal of the User model to handle this logic. from django.db.models.signals import post_save from django.db import transaction from django.contrib.auth.models import User from myapp.models import Setting @receiver(post_save, sender=User) def create_default_setting(sender, instance, created, **kwargs): if created: transaction.on_commit(lambda: Setting.objects.create(user=instance)) I used transaction.on_commit to make sure that the creation of the Setting record happens only after the User creation transaction is committed, to avoid issues where the User instance might not yet exist in the database. However, this separates the Setting creation from the User creation transaction. If for any reason the Setting creation fails (e.g., validation errors, database issues), I end up with a User record without a corresponding Setting, which violates data integrity. On the other hand, if I don't use transaction.on_commit and create the Setting directly in the post_save signal, there is a risk of attempting to create a Setting record before the User instance is fully saved in the database, or creating a Setting even when the User creation fails due to an uncommitted or rolled-back transaction. This leaves … -
Proper approach to login user in Django channels websockets?
Developing a dashboard using Django channels, two different consumers are implemented, UserConsumer and RequestConsumer. In UserConsumer methods like login, logout and get_user are implemented. The user Authentication is being done using OTP code sent to user mobile so that a user_send_code method is in charge of sending SMS while the user_login method verifies the code sent by user. UserConsumer is implemented as follow: class UserConsumer(AsyncJsonWebsocketConsumer): async def connect(self): await self.accept() async def receive_json(self, content=None, **kwargs): action = content.get("action", "user.get_user") if action == "user.login": await self.user_login(content) elif action == "user.send_code": await self.user_send_code(content) elif action == "user.logout": await self.user_logout() else: await self.user_get_user() async def user_send_code(self, content): await self.send("we will send sms to: {}".format(content['mobile'])) if check_mobile_pattern(content["mobile"]): code = random.randint(1111, 9999) self.scope[VERIFY_CODE] = code self.scope[MOBILE] = content["mobile"] result = await send_sms(content["mobile"], code) if result: await self.send_json(send_code(200)) else: await self.send_json(send_code(400)) else: await self.send_json(send_code(SystemErrorCodes.InvalidMobilePattern)) async def user_get_user(self): if self.scope['user'].is_authenticated: await self.send_json({"id": self.scope['user'].id}) else: await self.send_json(send_code(SystemMessageCodes.AnonymousUserMessage)) async def user_login(self, content): verify_code = self.scope.get("verify_code") code = content.get("code") mobile = self.scope.get(MOBILE) if mobile is not None and verify_code is not None and code == verify_code: user = await load_user_by_mobile(mobile) del self.scope[VERIFY_CODE] # login the user to this session. await login(self.scope, user) # save the session (if the session backend … -
Django app failing to get deployed on Azure web service

I then added some Azure OAI code using semantic-kernel and since then haven't been able to complete the deploy step of github actions workflow to deploy the app. To use semantic-kernel, I had to update to python 3.11 from python 3.8 on Azure. The deployment runs for about 40 mins and then errors out. From docker logs, I see the following issue:ModuleNotFoundError: No module named 'django' 2024-12-30T01:12:32.6106267Z Using packages from virtual environment antenv located at /home/site/wwwroot/antenv. 2024-12-30T01:12:32.6117557Z Updated PYTHONPATH to '/opt/startup/app_logs:/home/site/wwwroot/antenv/lib/python3.11/site-packages' 2024-12-30T01:12:35.1840122Z [2024-12-30 01:12:35 +0000] [84] [INFO] Starting gunicorn 23.0.0 2024-12-30T01:12:35.3134084Z [2024-12-30 01:12:35 +0000] [84] [INFO] Listening at: http://0.0.0.0:8000 (84) 2024-12-30T01:12:35.3205313Z [2024-12-30 01:12:35 +0000] [84] [INFO] Using worker: sync 2024-12-30T01:12:35.3321195Z [2024-12-30 01:12:35 +0000] [89] [INFO] Booting worker with pid: 89 2024-12-30T01:12:35.4238708Z [2024-12-30 01:12:35 +0000] [89] [ERROR] Exception in worker process 2024-12-30T01:12:35.4473148Z Traceback (most recent call last): 2024-12-30T01:12:35.4475461Z File "/opt/python/3.11.10/lib/python3.11/site-packages/gunicorn/arbiter.py", line 608, in spawn_worker 2024-12-30T01:12:35.4476786Z worker.init_process() 2024-12-30T01:12:35.4477986Z File "/opt/python/3.11.10/lib/python3.11/site-packages/gunicorn/workers/base.py", line 135, in init_process 2024-12-30T01:12:35.4479379Z self.load_wsgi() 2024-12-30T01:12:35.4480603Z File "/opt/python/3.11.10/lib/python3.11/site-packages/gunicorn/workers/base.py", line 147, in load_wsgi 2024-12-30T01:12:35.4481752Z self.wsgi = self.app.wsgi() 2024-12-30T01:12:35.4484237Z ^^^^^^^^^^^^^^^ 2024-12-30T01:12:35.4485531Z File "/opt/python/3.11.10/lib/python3.11/site-packages/gunicorn/app/base.py", line 66, in wsgi 2024-12-30T01:12:35.4486749Z self.callable = self.load() 2024-12-30T01:12:35.4487911Z ^^^^^^^^^^^ 2024-12-30T01:12:35.4489069Z File "/opt/python/3.11.10/lib/python3.11/site-packages/gunicorn/app/wsgiapp.py", line … -
How to Customize Indigo Theme and CSS Variables for Micro-Frontends in Open edX?
I’m working with Open edX, specifically using the Indigo theme and Micro-Frontends (MFEs). I want to customize the theme by setting CSS variables or tokens to maintain consistent branding across the platform. However, I’ve run into some challenges and am not sure how to proceed. My Setup: Open edX platform is hosted with the Indigo theme. I’m working with Tutor for managing the Open edX instance. The Micro-Frontends (React-based) are running on apps.local.edly.io. What I’ve Tried: I’ve looked into modifying the Indigo theme’s Sass variables (e.g., $primary-color) but couldn’t figure out the process to make these changes take effect. I don’t have React components inside the indigo-theme folder to directly manage styles or tokens for MFEs. I’ve come across mentions of the edx/brand package, but I’m unclear on how to use it to integrate the custom styles with MFEs. Questions: How can I customize the Indigo theme to define CSS variables or tokens? Is it possible to ensure these customizations are applied across both the core platform and the MFEs? If yes, what’s the best way to do this? Do I need to modify or replace the edx/brand package for this, and how do I integrate it properly with Tutor-managed …
