Setting permissions between edit and view only in wagtail
In my Wagtail project, I have a class that inherits from EditView(modelAdmin). Within this class, I override the get_edit_handler method to dynamically set fields as read-only based on user permissions. However, I'm encountering an issue with RichTextField fields: the permission settings only take effect after restarting the application. For example, if I set an InlinePanel to read-only, all InlinePanel instances that include RichTextField fields across the model also become read-only, regardless of their individual permission settings. class JournalEditView(EditView): def form_valid(self, form): self.object = form.save_all(self.request.user) return HttpResponseRedirect(self.get_success_url()) def get_edit_handler(self): """ Overrides the get_edit_handler method from EditView. It checks whether the user has permission to edit each field. If not, the fields for which the user lacks the journal.can_edit_{field_name} permission in their user_permissions will be set as read-only. This applies to FieldPanel, AutocompletePanel, and InlinePanel. """ edit_handler = super().get_edit_handler() user_permissions = self.request.user.get_all_permissions() if not self.request.user.is_superuser: for object_list in edit_handler.children: for field in object_list.children: if isinstance(field, FieldPanel) and f"journal.can_edit_{field.field_name}" not in user_permissions: field.read_only = True elif isinstance(field, InlinePanel) and f"journal.can_edit_{field.relation_name}" not in user_permissions: field.classname += ' read-only-inline-panel' for inline_field in field.panel_definitions: inline_field.read_only = True return edit_handler class JournalAdmin(ModelAdmin): model = models.Journal inspect_view_enabled = True menu_label = _("Journals") create_view_class = JournalCreateView edit_view_class = JournalEditView -
Django CKEditor5 images not displaying on server
I am using Django 5.0 and django-ckeditor-5 to handle rich text stuff in my admin panel, including image uploading by staff. On my local machine (Win11), everything works fine. I can upload the image and it shows correctly in the admin view and in the site view. However, when putting it on my test server (Windows Server 2022, using IIS), when I upload an image, it flashes and then displays the default broken image. Attempting to navigate to the image directly gives a 404, but when I look at the URL of the image and physically find it on the server, its there and I can open it in paint. So the images are uploading into the correct place, the URL of the image in CK editor is showing the correct image, but the image does not want to load. Here is my path settings for the urls.py at the root and the media folder in settings.py urls.py ... urlpatterns += [ path("ckeditor5/", include('django_ckeditor_5.urls')), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) settings.py ... STATIC_URL = '/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') The setup is identical for both local and on the server in terms of folder structure, the media folder is … -

Django: Saving automated JSON POST from software (no user form!) in several tables (models)
Needed to save POST data in several tables\models in 2 apps (one - only 4 POST receiving) , depending on POST content. One model - ActionFeed will be JSON field and save all input, others - conditionally, looking on various JSON POST values Input data is looking like { "timestamp":"2025-04-29T07:15:12Z", "event":"MissionAccepted", ... } #schematically json_data = json.loads(post_input) Save2ActionFeed (post_inpt) if event=="MissionAccepted" #get neeses fields from json data save2Missionsions (field1, ... , field N) if event=="FSDJump" #get neeses fields from json data save2Location(field1, ... , field M) etc. Needed a sample of save2... methods, please, remember, than no forms, UI, etc - only clean POST -
Django [Postgreq] restore single field/column
I have a model with field creation_date = models.DateTimeField(auto_now_add=True). Doing some complex manipulations with migration file (converting model to multi-table inheritance and creating new objects) I've accidentally overwriten the field above. I have backups but need to overwrite only the single field creation_date as there are some fields in table are not align with current state. I guess there is a way to dump (id, creation_date) in JSON file and update the corresponding objects with for loop. Is there a way to pull data from gzip backup and save it to .json ? Or some more easier way to go? -
How to to debug DB errors in flaky frontend tests with django, htmx and playwright
I'm running a larger Django app that has a test suite that runs both on Debian Bookworm and Trixie. The tests use the test_server fixture and sqlite. We're currently experimenting with HTMX based views, which we test using playwright. A few weeks ago the test covering our new HTMX view started occasionally failing, but only ever on Trixie. The only relevant packages provided by the Debian Trixie host are sqlite 3.46 and python 3.13. Everything else comes in via pip and pyproject.toml in the same versions as on Bookworm. The test does not fail reliably and when it does fail, it doesn't always fail with the same error. The only commonality is that it always fails while trying to get the current session, in order to authenticate the request user (the tested view has an auth decorator). The error messages include django.contrib.auth.models.User.MultipleObjectsReturned: get() returned more than one User -- it returned 2! django/db/models/sql/compiler.py stepping out with List index out of range when trying to load the session cache django.db.utils.InterfaceError: bad parameter or other API misuse when trying to get the session cache.

Django + DigitalOcean Managed PostgreS: “remaining connection slots are reserved for roles with the SUPERUSER attribute” when using connection pooling
I’m trying to configure Django to use a connection pool against a DigitalOcean Managed PostgreSQL instance, but keep running into this error: OperationalError: connection failed: connection to server at "xxxxxxxxxxxx", port yyyy failed: FATAL: remaining connection slots are reserved for roles with the SUPERUSER attribute My DATABASES setting looks like this (Django 5.2+): DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': database_name, 'USER': database_user, 'PASSWORD': database_password, 'HOST': database_host, 'PORT': database_port, "OPTIONS": { 'sslmode': sslmode, 'pool': { 'min_size': 5, 'max_size': 150, 'timeout': 20, }, } } } Is this the correct way to enable pooling via Django’s built-in OPTIONS['pool'] settings? -
Why am I getting "ERR_CONNECTION_REFUSED" when querying by sidecar-hosted backend in Azure App Service?
I'm trying to deploy a fairly basic web app in Azure App Service. I have a backend image (running django+graphql) and and a frontend image (running vue+apollo), and when I run them locally either separately or via docker-compose it works with no issues.

How can I properly test swagger_auto_schema for methods, request_body, and responses in drf-yasg with pytest?
I’m working on testing a Django REST Framework (DRF) CartViewSet using pytest, and I need to verify the swagger_auto_schema properties like the HTTP method, request body, and responses for different actions (e.g., add, remove, clear). I have the following code in my CartViewSet: class CartViewSet(GenericViewSet, RetrieveModelMixin, ListModelMixin): # Other viewset code... @swagger_auto_schema( method="post", request_body=AddToCartSerializer, responses={ 201: openapi.Response(description="Item added successfully."), 400: openapi.Response(description="Invalid input data"), }, ) @action(detail=False, methods=["post"], url_path="add") def add(self, request): # Logic for adding an item to the cart pass Now, I want to write a pytest unit test to check the following for the add method: HTTP Method: Ensure the swagger_auto_schema method is POST. Request Body: Ensure the correct serializer (AddToCartSerializer) is set for the request body. Responses: Verify that the response status codes (201 and 400) and their descriptions are properly set. Could someone guide me on how to properly test the swagger_auto_schema properties for method, request body, and responses in pytest? Any help or insights would be greatly appreciated! -

How to check if a django queryset has a matching manytomany + foreignkey?
I try to check - in Djnago - if a user made queryset has two fields out of three which match 100%. class Foo(models.Model): # ... free_field = models.ForeignKey(FreeModel, ...) must_match_m2m_field = models.ManyToManyField(ManyModel, ...) must_match_fk_field = models.ForeignKey(BarModel, ...) # ... So, user generates a queryset of the "Foo" model (with several objects in it), which may contain many objects with a) different FreeModels, and b) precisely matching ManyModels & BarModels. In backend I need to check that all ManyModels and BarModels match in the query. for the ForeignKey objects I made following (I think its fair enough): def check_same_objects(object_list): return len(set(object_list)) == 1 check_bars = check_same_objects(qs_foo.values_list('must_match_fk_field', flat=True)) I made this for comparing the lists of objects in the manytomany fields of each object: def check_same_lists(object_lists): for lst in object_lists: if set(lst) != set(object_lists[0]): return False return True should_match_foos = [] for e in qs_foo: should_match_foos.append(e.must_match_m2m_field.all().values_list('id', flat=True)) check_manies = check_same_lists(should_match_foos) # finally checking both 'must-match-fields': check_both = all([check_bars, check_manies]) What is the more elegant pythonic/djnago variant of checking if theese two fields match 100% in the whole qs? -
Django Channels WebSocket connects but immediately closes (Live chat app)

Using Asych in Django views to connect to LiveKit Backend throws missing arguments

Dynamic initial values for a Django Model
How would i go about prepopulating a field in the Wagtail Admin UI with HTTP GET parameters? I have seen some solutions using the deprecated contrib.ModelAdmin, but have not really found something using the new ModelViewSet. My simplified use case would be a simple calender in the Admin UI (using some javascript calender like fullcalandar.js) where i would create a new Event by dragging a timeframe and having the browser visit an url like /admin/event/new?start=startdate&end=enddate showing the Event Form with the start and end fields being prepoulated by the timeframe. I have the following model class Event(models.Model): title = models.CharField(max_length=255) [...] class EventOccurrence(Orderable): event = ParentalKey(Event, on_delete=models.CASCADE, related_name='event_occurrence') start = DateTimeField() end = DateTimeField() So far i have tried to use an Custom Form Class inherting from WagtailAdminModelForm, which works nicely for the prepopulating, but i have no way to access the request object to fetch the GET paramters. Helpful AIs would like me to use the deprecated ModelAdmin or inject some javascript to prepopulate the fields on the frontend.

Translate external lib text Django
I currently use Base64ImageField from drf_extra_fields in a serializer. This class uses INVALID_FILE_MESSAGE = _("Please upload a valid image.") and _ comes from from django.utils.translation import gettext_lazy as _ I implemented translations (from english to french) with pyhton manage.py makemessages and pyhton manage.py compilemessages to us them. But to translate the error message from Base64ImageField, i did not found any relevant solutions: Write the translation myself in django.po file, but as soon as i make ```python manage.py makemessages`` it's going to be commented out. Avoid my custom translation being commented out by having a file.py with _("Please upload a valid image.") Write a custom makemessages command to avoid translation being commented out Is there any other solution or only "dirtry tricks" work for this issue ?
