How can I execute ModelAdmin.save_model asynchronously?
A Django-based website I'm building may occasionally need to run shell commands when initiated by an administrative user. Anticipating this, I decided it would be a good idea to write these processes to be asynchronous considering asyncio supports shells right out-of-the-box. I am executing these processes from the save_model() function of ModelAdmin, not an async view. My issue is when long-running processes are executed, the supposedly 'async' server gets completely hung-up on them and doesn't answer any other requests from clients until they are finished. I'm 100% certain this is because I'm running these processes in a sync function, albeit asynchronously (see below). I need to be able to tell the administrative user if the process they are running has succeeded or failed. I'm currently doing this through the messages API provided by Django. Here is the function executing the shell commands (Linux): import asyncio import sys async def run_subprocess(cmd: str) -> Tuple[int, bytes, bytes]: """Run a subprocess command asynchronously. Notes: This will execute the subprocess in a shell under the current user. Args: cmd (`str`): The command to run. Returns: exec_info (`tuple`): `(retcode, stdout, stderr)` from the subprocess for processing. """ # Create an execute the future try: proc … -

Django-Storages with SFTP: GET-requests fail
I a trying to use django-storages to access my "Hetzner" Storage Box (https://www.hetzner.com/storage/storage-box) using SFTP which should hold media data, i.e. image files which users of my website can upload dynamically. The corresponding part of my settings.py file looks like: DEFAULT_FILE_STORAGE = 'storages.backends.sftpstorage.SFTPStorage' SFTP_STORAGE_HOST = 'username.your-storagebox.de' SFTP_STORAGE_ROOT = '/media' SFTP_STORAGE_PARAMS = { 'username': 'username', 'password': 'password', 'allow_agent': False, 'look_for_keys': False, } The strange thing is that, when the user uploads an Image, it is placed on the storage space as I can confirm using SFTP. But getting the images from the storage box fails, no Image is displayed. An excerpt from the console: [03/Sep/2021 22:34:01] "GET /media/filename.jpg HTTP/1.1" 404 1962 I could figure out that Django is still looking inside my MEDIA_DIR for the files. Againg, the corresponding part of my settings: MEDIA_DIR = 'media' MEDIA_ROOT = os.path.join(BASE_DIR, MEDIA_DIR) MEDIA_URL = '/media/' So in a nutshell: Using SFTP seems to be working for putting files into storage, but getting them again somehow fails. I am hoping for some help. Thanks in advance! -
Django Celery broken after moving secret key to environment variable
I'm working on a Django project that uses Celery for periodic tasks. For improved security, I moved Django's SECRET_KEY into an environment variable. The app ran fine, so Django was certainly able to find the environment variable and set the SECRET_KEY. But an unexpected side effect was that all the regularly occurring Periodic Tasks stopped triggering. I was able to run the tasks manually from Django Admin, so the Celery workers were still alive and well, but the tasks wouldn't trigger themselves like they usually do. The app settings and Celery config are both located in a directory called server. Here's the file structure: -server -__init__.py -celery.py -settings.py Before moving the secret key, it was in settings.py like this: SECRET_KEY = "secret" After moving to an environment variable, the line in settings.py was like this: SECRET_KEY = os.environ.get("SECRET_KEY") And here's the contents of celery.py, in case that's relevant: os.environ.setdefault("DJANGO_SETTINGS_MODULE", "server.settings") app = Celery("server") app.config_from_object("django.conf:settings", namespace="CELERY") app.autodiscover_tasks() As soon as I moved the secret key out of the environment variable and back into settings.py, the tasks started firing again. I'm hoping to figure out why moving the secret key broke the periodic tasks so I can move the secret key back … -
Django Migrations stuck after executing in incorrect order
I made two changes to different models in my database. The first operations = [ migrations.DeleteModel( name='Settlement', ), ] And the second: operations = [ migrations.RemoveField( model_name='invoice', name='settlement_deducted', ), migrations.RemoveField( model_name='invoice', name='settlement_supporting', ), ] The issue is that they ran in this order, and the second one failed. The field being removed in the second migration uses the "Settlement" model, but since that model was deleted in the first migration it throws this error: ValueError: The field invoices.Invoice.settlement_deducted was declared with a lazy reference to 'accounting.settlement', but app 'accounting' doesn't provide model 'settlement'. The field invoices.Invoice.settlement_supporting was declared with a lazy reference to 'accounting.settlement', but app 'accounting' doesn't provide model 'settlement' Now when I try to do anything to fix it, it seems to just be stuck in that error state and continuously throws that same error. I have tried reverting the first migration to the previous migration on that model, adding that model back in and running makemigrations and then migrate so that the Settlement model exists again, and deleting the second migration (though it was never run anyway). All of these options are still throwing the same error. I am surprised that Django didn't catch this dependency issue … -
Reportlab in Django Application error - Forbidden (CSRF token missing or incorrect.)
I come from more of a data science background, but for fun I have been building a web application. I am new to django, javascript, and HTML, and it's a lot to wrap my head around - so if my coding appears unconventional I apologize. Feel free to offer any feedback. Within my application, I am trying to create a button on a webpage that does the following: Reads data input from an HTML table entered by the user in JavaScript (as an array). Using ajax, sends the data to a Python view. There, a function will be performed on the array, and the output will be returned to the user as a PDF generated by the reportlab library. Unfortunately, I continue to get the following error: Forbidden (CSRF token missing or incorrect.): /get_custom_bingo Here is the full error: Forbidden (CSRF token missing or incorrect.): /get_custom_bingo [03/Sep/2021 16:07:17] "POST /get_custom_bingo HTTP/1.1" 403 2513 [03/Sep/2021 16:07:17] "POST /pages/custom_bingo.html HTTP/1.1" 200 4320 [03/Sep/2021 16:07:17] "GET /static/JS/scripts.js HTTP/1.1" 304 0 I have tried to get it to go away, but nothing I can find online seems to be helping my current scenario.

Custom Django form validator doesnt render validation error on the frontend

Validating string for possible space returns error in Django form even though there's no space

So to have some validation in the view i created the following validator (idea is to search for spaces): Views.py [..] if ' ' in poller_choice_one or poller_choice_two: raise ValidationError(('Limit your choice to one word'), code='invalid') else: [..] To make it more robust I added the strip option to the FormFields to be validated: # Poller Choices poller_choice_one = forms.CharField(label='Choice one', max_length=20, strip=True) poller_choice_two = forms.CharField(label='Choice two', max_length=20, strip=True) I tried like a bunch of inputs from single digits to single chars etc., it always raises the validation error -
Custom Functions in Django Model
I am building a FedEx API in django and currently have a Shipment class which has methods such as create_shipment(), delete_shipment()... I have stored this shipment class in a separate file. I created a Shipment model inside my models.py and I noticed that it seems inefficient to have two different Shipment classes (one for the django model and the other defined in a separate file). I want to know if it would be considered bad practice to define the functions of the API inside the same model class. I want process_shipment() to be called by the model and then insert the instance into the database. Note that to do this I'd need to overwrite the init method of the parent model class which I hope will be ok. -
Django Rest Framework + Serializers + Vue.js, Reset Password Functionality
I am trying to create a reset password functionality, but I can't find a good tutorial that explains how to do that with DRF and Vue.js. I am using serializers to pass the data, so there are no html views involved. What is the most efficient way of creating that Reset Password Functionality? I am creating new users via /api/v1/users/. Any ideas are very appretiated. Thank you! -

How to pass in the user in the request for Auth0? (React Frontend and Django Backend)

https://docs.pytest.org/en/6.2.x/warnings.html#deprecationwarning-and-pendingdeprecationwarning teaches me to use this in my pytest.ini filterwarnings = ignore:.*U.*mode is deprecated:DeprecationWarning but i still get warnings that are like this: ../usr/local/lib/python3.8/dist-packages/django/apps/registry.py:91 /usr/local/lib/python3.8/dist-packages/django/apps/registry.py:91: RemovedInDjango41Warning: 'pattern_library' defines default_app_config = 'pattern_library.apps.PatternLibraryAppConfig'. Django now detects this configuration automatically. You can remove default_app_config. app_config = AppConfig.create(entry) I would like to suppress this as well, as this is also a third party library of which I have no control over even though i have laready submitted a PR to update it. What should i add to my pytest.ini? -
