Django FileField with custom storage still uploads to default storage (GoogleCloudStorage)
I want to upload files to custom storage, other than the one for static. But each time when i try to declare a custom google cloud storage bucket, it still refers to the bucket related to statics (probably to the default storage) I am trying to Declare a new class from wagtail's AbstractDocument class class VirtualVisitDocs(AbstractDocument): file = models.FileField(storage=CustomGoogleCloudStorage(), verbose_name=_('file')) Then using it as a foreign key for another wagtail page with document chooserpanel as follows: virtual_visit = models.ForeignKey( VirtualVisitDocs, on_delete=models.SET_NULL, verbose_name=_('Virtual Visit Zip File'), related_name='promotion_pages', null=True, blank=True, ) MultiFieldPanel( [ DocumentChooserPanel("virtual_visit"), ], heading=_("Virtual Visit"), classname="collapsible collapsed", ), The storage instance from above CustomGoogleCloudStorage is the one which I have declared as follows: @deconstructible class CustomGoogleCloudStorage(GoogleCloudStorage): def get_default_settings(self): default_settings = super().get_default_settings() default_settings['bucket_name'] = settings.GS_VIRTUAL_TOUR_BUCKET_NAME default_settings['project_id'] = settings.GS_VIRTUAL_PROJECT_ID return default_settings Each time I try to upload documents this way, I get HTTP 403 which is correct, cause the service account I am using is not allowed to make changes on the default bucket. Rather, I want files to be uploaded to the second bucket where my service account is allowed to create bucket instance objects, but I just can't point to that another bucket. Whenever I try to print custom CustomGoogleCloudStorage … -

How can I use 2 websocket in same page?

How do i modify my create function in Django model manager
So i have this model: class Token(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=False) code = models.IntegerField(default=code) date_created = models.DateTimeField(auto_now_add=True) expiration_date = models.DateTimeField(null=False, blank=True) as you can see I have an expiration_date field. The reason why I set it to (null=False, blank=True) is because I want it to fill itself based of the date_created field, and I'm trying to do that from the model manager create method I have little to no experience in model manager outside of custom user model manager. Here's my first failed attempt: class TokenManager(models.Manager): def create(self, user, code, date_created): exp = date_created + datetime.timedelta(minutes=10) token = self.model(user=user, code=code, date_created=date_created, expiration_date=exp) token.save() return token basically my goal here is to get the value of date_created field, add the value by 10 minutes and set it as the expiration_date. can anyone help me with this? -

WebSocket like grouping for Server Sent Events in Django
I have a Django website and I have a real-time "game" on it. Multiple people connect and play it. Every x seconds the users in the specific game will be getting updates. I have done this using WebSockets and it works, I would say, pretty good. The things I think that using WebSocket-s is an overkill, plus I'm not utilising the Bi-directional part of it, rather using it to get the updates from the server and using AJAX to send the data. I'm considering switching over to Server Sent Events. I've used it a bit and read about it online and have decided that it would be a good fit for my project (using it instead of WS). The "problem" that I have is that I'm not sure how to (I assume its possible) use something like a groups in ws. I've searched online and the best solution that I could find is doing the client side filtering, which although its totally fine, I do not prefer as I think it's a waste of resources. The way that I have it set up is that based on the url for the game, the users that are connecting would be placed … -

django admin search by foreign key in add form
In the form to add new objects in Django admin, sometimes there are linked foreign keys that are selectable in a dropdown. Is there a way to include a searchbox for the foreign keys within the form? For example, let's say I have a Book model with a foreign key to Author object. Instead of scrolling through all the author ids when I create a new Book object, can I search for Author "James" specifically? -

can I grab some specific third api data as an additional property to my django api view?
I have an api view which fetches data from its model. I want this api view to have an additional value from third party api.

Strange behaviour when deleting items using Django and React stack applications
I work on a full stack application that is composed of: Django (Django Rest Framework) React PostgreSQL database Redis Celery It is deployed through docker. Whole application works well and has no bugs that cannot be traced. However, when I try to delete Project item from database (this is domain specific), I get error 500 and no specific trace. I figured this bug out on deployed application. While inspecting Networking tab in Developer Tools I found the request and saw 500 return code. However, nothing was returned in returned in Response. However, I think something should have been returned. Code is as such: class ProjectCRUD(GenericAPIView): # [...] def delete(self, request, pk): try: # [...] code that deletes all referenced values and current project except ProtectedError as e: return JsonResponse({ "error": "Project still referenced", "details": str(e) }, status=400) except Exception as e: return JsonResponse({"error": "Wrong project id"}, status=status.HTTP_400_BAD_REQUEST) return JsonResponse({ 'message': f'Project with id {project_id} was deleted successfully!' }, status=status.HTTP_204_NO_CONTENT) # [...] This "Wrong project id" assumption is by all means bad and this will be refactored as soon as this bug is also found.
