Uploaded media doesn't server in production mode without restarting django
I need to serve media in Django in production mode and it is very little need to serve telegram user photos in Django admin. so I know everything about Django it's not for serving files or media so there is no need to repeat repetitive things. I just need to serve media in production mode for my purpose so I use WhiteNoise to do this and append this lines: MIDDLEWARE = [ ... 'whitenoise.middleware.WhiteNoiseMiddleware', ... ] STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'medias') in urls.py: from django.conf import settings from django.conf.urls.static import static from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('botAPI.urls')), ] if settings.DEBUG: urlpatterns += static(settings.STATIC_URL, document_root=settings.STATICFILES_DIRS[0]) urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) else: urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) in wsgi.py I put this: ... application = get_wsgi_application() application = WhiteNoise(application, root=MEDIA_ROOT, prefix='/media/') .... It works correctly and serves media files in production mode. but for new media for example uploading an image in Django admin I have to restart Django to access that media. is there any way to solve this problem or another way in Django to serve … -

How can I pass headers in Swagger UI?
I am trying to hit the API using Django Swagger UI, but I am not getting header in API. I have tried all the answered solutions but I don't know how none of them worked for me. What am I doing wrong?

Here is my API view: from rest_framework.permissions import IsAuthenticated from drf_spectacular.utils import extend_schema from rest_framework.views import APIView from rest_framework.response import Response authorization_params_in_header = OpenApiParameter( "Authorization", OpenApiTypes.STR, OpenApiParameter.HEADER, required=True ) class ProtectedView(APIView): permission_classes = (IsAuthenticated,) @extend_schema( tags=["Protected"], parameters=[authorization_params_in_header], responses={200: "Success"}, ) def get(self, request): data = {"message": "This is a protected resource"} return Response(data) When I hit the API, even if I put header in the field, Swagger does not pass it in curl also, which you see in picture below. -
Change title (verbose name plural) in custom admin.TabularInline
In my Django admin UI I use a TabularInline like this: class MyCustomInline(admin.TabularInline): # ... def get_queryset(self, request): # ... The overridden functions adds a filter, so that only a subset of related objects is displayed. In the admin UI I get table using the plural of the model class as title, which is wrong in this case. I would like to give it a custom name. I cannot do this for the model itself, because I want to change the title only for this filtered set. Not for the model class in general. I tried to figure it out from the source code. In the template I found out that the verbose_name is passed in via opts, but could not follow its path to find a way to override it. Could somebody give me a hint how to change the title aka verbose name just for this specific TabularInline? -

Django create() not applying annotations applied on manager
Imagine the following model, manager and queryset: from django.db import models class BlaQuerySet(models.QuerySet): def annotate_field(self): return self.annotate(bla_field=Value('Bla') class BlaManager(models.Manager): def get_queryset(self): return BlaQuerySet(self.model, using=self._db).annotate_field() class Bla(models.Model): hello = models.CharField(max_length=10) Now that we have the model. Let's create something: bla_instance = Bla.objects.create(hello='something') bla_instance.bla_field returns `AttributeError: 'Bla' object has no attribute 'bla_field' On the other hand, when you filter that item: bla_instance = Bla.objects.get(hello='something') bla_instance.bla_field returns the expected Bla How can I force the create() to use my manager instead of the default one? -
dj-rest-auth with JWT (problem with login functionality)
I have problem with login functionality, when the first time I log in it returns csrf_token, access_token and refresh_token . and it works fine till the expiration time. I know when the access token is expired I should get new one through refresh token but it should also work when I directly use the login route and giving username and password but I get error: { "detail": "Given token not valid for any token type", "code": "token_not_valid", "messages": [ { "token_class": "AccessToken", "token_type": "access", "message": "Token is invalid or expired" } ] } and when I see the cookies part the previous values are still there shouldn't they be vanished? I think the problem origins from here. when i manually delete them it works fine. and even when the refresh token expires I get the same error, how does it work? -
Using Django Debug Toolbar With DRF, Simple JWT Auth
django-debug-toolbar needs its output to be html, but i am using apis with jwt authentication (djangorestframework-simplejwt). So i am unable to use debug toolbar. I have all the settings of IPs, Middlewares everything correct as per documentation. All my APIs have Authentication and Authorization. All my libraries, modules are in latest versions. I have tried these methods Using django spectacular and creating an Swagger Documentation for my APIs, but it is not generating correct documentation (my apis work on many models, so unable to generate correct schema), Many Schemas are missing and also i dont know why extend_schema is not working. Used django-debug-panel by changing the errors with views.py, urls.py, middleware.py in django-debug-panel and also installed the chrome extension but i dont understand how to use it. Used django-silk but i want to use debug toolbar. Is there anyway i can use django debug toolbar somehow? I want to try again with any new ideas or changing anything in those methods i mentioned -
At least one element of a list and not all element of a list must match for a many to many relationship query in django
Here i have a list of place and tags for a reservation : And i would like a query where at least one of the list of places and at least one of the tags need to match the query slot, and not all places and not all tags need to match for the slot reservation. here is my solution : tags = Tag.objects.filter(name__in=tags) print("tags", tags) places = PartnerPlace.objects.filter(zip_code__in=cps) print("places", places) #slots is a queryset slots = Slot.objects.filter() for place in places: for tag in tags: slots = slots | Slot.objects.filter( tag=tag, place=place, ) It works but i think it's not elegant nor optimal if anyone have a better solution.
