Another "fk_name ' ' not a foreignkey to" problem [Python/Django]

Form wont validate, says that all fields are empty Django

Custom Auth Backend
I am looking to create a custom auth backend for my Django project using one field for private key. How to achieve that with removing the "django.contrib.auth.backends.ModelBackend" and replace it with the new auth? Simply, if private key match public key in the database, login that user, else raise error. Note, at the moment all users have public key (RSA) stored in the database, and the private key in stored in the sessions. -

request.get: Temporary failure in name resolution. Cannot use Session()
Inside of a Django web app, I synchronously call an external API using requests. request(url=api_url, method="GET") This gets called roughly 1 or 2 times per minute, and can scale up to 10 times per minute. It mostly works fine, though sometimes I get this error: HTTPSConnectionPool(host='example.com', port=443): Max retries exceeded with url: /api_url/endpoint.json (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f637a4e63a0>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')) Now, I understand the correct solution would be to use Session() so that the underlying TCP connection is reused and requests doesn't have to perform a name resolution every time (which, as we've seen, could sometime fail for no avoidable reason). However, Session() would not persist once my Django app has responded to the user. The app works synchronously: I would need an external service that persists the TCP connection to external APIs, only for this purpose... that'd be madness. More simply, I'd like to cache the name resolution somewhere, potentially for days. Is this possible? I have the IP address the api_url resolves to. But I obviously can't query that directly. What's the solution here? -
Best way to declare additional data in Django project
I'm looking for the best practice in order to declare the additional data in a Django project. Imagine I need to store a huge list of choices to use in app1/models.py (I have seen a lot of best practices keep declaring those choices in the body of the models). In another scenario, Imagine I need to keep tens of config data in order to use them in my views.py. Is it common to declare them in the function/class? In my opinion, there would be two common methods in order to do that. (Not sure even recommended at all) Method #1 I can actually keep them all in my settings.py file and access them with importing (like from django.conf import settings). settings.py: ... NBA_TEAMS = ( ("red", "Bulls"), ("yellow", "Lakers"), ... ) Method #2 Keep them all in a file named data.py right next to the settings.py, and try importing it at the end of the settings file like this. settings.py ... try: from .data import NBA_TEAMS, .. except: pass Is there any best practice about this issue? Thank you. -

Force tests to fail if migrations aren't run
I'm blatantly oblivious sometimes, and it led me down a 30 minute blackhole trying to figure out why my constraints weren't being applied in my tests. Turns out I forgot to run makemigrations. Is there a way to configure pytest or django to fail without makemigrations? I know if very clearly warns me Your models have changes that are not yet reflected in a migration, and so won't be applied. Just looking for something a little more obvious/in your face? -

Why does Django add a dollar sign in my URL pattern? (

I am having problems with crispy_forms and formsets
I am using django_crispy_forms and have 2 formsets within the main form. The formsets are generating & saving data correctly, except for the first row, the data is never saved. In the source of the page, the first row does not have an instance number and the second row has an instance number of 0. for example, the id of vegetationType for the first row is id_vegetation-prefix-VegetationType, for the second row it is id_vegetation-0-VegetationType. If I remove the formhelper from the html page ({% crispy formset_vegetation%} instead of {% crispy formset_vegetation formset_vegetation.form.helper%}, the formset renders correctly without the extra row at the top, but the rows are not formatted as an inline formset.

How to route to specific viewset methods Django
I've been studying the viewset and router docs for Django and I can't figure out how to set up a route to access the method on a viewset. For example, here is my urls.py: from rest_framework.routers import DefaultRouter from users.views import (UserViewSet, testing) router = DefaultRouter() router.register(r"users", UserViewSet, basename="users") urlpatterns = [ path('testing', testing) ] And then this is my views file in my user directory @csrf_exempt class UserViewSet: def create(self): return JsonResponse({ 'the create endpoint' }) @csrf_exempt def testing(request): return JsonResponse({ "title": "My json res" }) Using postman, I can hit the endpoint example.com/testing and have the json response logged out. However, I try to hit example.com/users/create and I get a 404. I thought the basename propery when registering the viewset with the router would group all of the methods inside that class under that route path and then the methods would all be their own endpoint. Am I thinking about this incorrectly? Any help would be lovely as I am new to Django. I've mostly done Express and Laravel. Thanks! -

Upload a file in Django Admin, but not as a model's FileField
I'm working with Django 3 and I need to upload a (zip) file via the Django Admin. All the information that I've found online refers to uploading files as a models' FielField. But in my case, I don't want to associate the uploaded file to any model. I just want to upload it and run a certain management command based on its content, and delete it afterwards. If needed, I can use JQuery in the Django Admin pages to help accomplish this goal. Any pointers on how to do this? -

Django + gUnicorn timing out with POST requests with large sizes
Sending a 'large' POST request to gUnicorn will cause it to freeze and eventually timeout. This is both on my production server and development server (both running Ubuntu 20.04). It just freezes before returning [CRITICAL] WORKER TIMEOUT (pid:10000) Django's default dev server works without issues. My WSGI file: import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'djangoProject.settings') application = get_wsgi_application()
