Django Rest Framework Excel File Upload
Note: Please read the whole question before marking it as duplicate. Django has changed ALOT Since a couple of years. I have already tried all the solutions and read Django Rest Framework Documentation on: FileUploadPasrer https://www.django-rest-framework.org/api-guide/parsers/#fileuploadparser MultiPartParser https://www.django-rest-framework.org/api-guide/parsers/#multipartparser. None of the ways work. I also tried uploading using simple Django but that didnt seem to work Either. The Error I am getting is that request.FILES['file'] is always an empty {}. Write now my code looks like this parser_classes = [MultiPartParser] def put(self, request, format=None): file_obj1 = request.data['file'] data = json.loads(request.POST['form']) print(file_obj1) return Response(status=status.HTTP_201_CREATED) Like i said I always tried Using FileUploadParser. Same code just replaced MultiPartParser with FileUploadParser. I am using Postman to send an excel file and then reading it. Anyone who has recently upload an excel file in Django Rest Framework can guide me but make sure your code works becuase I have already spent a day and still can't find the solution so far. Edit: Curl Request from Postman would be: curl --location 'http://localhost:8000/amm-api/upload/upload_workbook/' \ --form '=@"/Users/razan/Projects/HTS/ags-carmax/Robbie_Lisa-Branch.xlsx"' This is how it looks in Postman -

Multi-database in django: Tables not dumped
I'm trying to demonstrate the use of multi-database in Django using db routers but facing issues dumping data into respective databases.

Javascript not loading in my Django + React Project with Vite.js
So I had created a project with React as frontend and Django as it backend. For the backend and frontend two separate folders were created : backend and frontends (ignore the spelling mistake it was intentional). I created a react project using vite.js and also created a build production by using the npm run build command. I then linked the dist folder which was generated to django through settings.py along with all other configurations needed for linking static files and stuff, editing views.py as well as urls.py. Below is the syntax for my STATICFILES_DIRS STATIC_URL = '/assets/' STATICFILES_DIRS = (os.path.join(REAL_BASE_DIR,'frontends', 'dist', 'assets'),) Also the directory tree of my project : screenshot So when I start the django server the static files successfully load (like the javascript and the .css) and its show 200 Success CODE and no 404 but in the console of my browser the following error shows up particularly for the Javascript file (not the css). error image The CSS file loads successfully with no errors but the Javascript file shows the above error and I can't find any possible solution on how to fix it. Expecting the JavaScript file to load since there were no 404 Not … -

What is the expected way to set `filterset_fields` in Django-Filter and Django REST Framework?
When I set the fiterset_fields like below, class SubCategoryViewSet(viewsets.ReadOnlyModelViewSet): filter_backends = [DjangoFilterBackend] filterset_fields = ["category_id"] # single underscore I get this response when a category with the specified ID doesn't exist { "category_id": [ "Select a valid choice. That choice is not one of the available choices." ] } But when I set it like class SubCategoryViewSet(viewsets.ReadOnlyModelViewSet): filter_backends = [DjangoFilterBackend] filterset_fields = ["category__id"] # notice the double underscore I get a [] when a category with the specified ID doesn't exist. Why does this happen? What is the right way to do this? -
Heroku Django app with AWS OpenSearch (anonymous user is not authorized issue)
I used to have an ElasticSearch Service instance (t2.micro.search) set up to enable a search functionality for an app hosted on Heroku. That old setup was working fine. I now tried to set up a new instance (t3.small.search) using the same settings as the previous one. However, when I tried to build the index from Heroku, I got this error: TransportError(403, '{"Message":"User: anonymous is not authorized to perform: es:ESHttpPost with an explicit deny in a resource-based policy"}' I realized my access policy has "Deny" instead of "Allow" I had before: { "Version": "2012-10-17", "Statement": [ { "Effect": "Deny", "Principal": { "AWS": "*" }, "Action": "es:*", "Resource": "arn:aws:es:us-east-1:000000000000:domain/my-domain/*" } ] } I tried to change it to "Allow" but the console would not allow me to save the settings ("Apply a restrictive access policy to your domain"). Does somebody know how to set up the access policy so I can continue to use AWS OpenSearch for a Heroku app? -
wagtail on-publish custom sucess message
I have a question regarding the success message wagtail is displaying when an editor is publishing a page in the admin interface. It's usually "Page {Page.title} has been published". I’am trying to figure out how to add one’s own success or error message on-publishing resp. an error occuring. For a Page in my project I have implemented the below receiver that gets activated if the editor uploads in a certain field a file and publishes the site. This file is then processed by a script, though the file itself is not saved. For the editors, I would like to have a custom success message displayed below the default on-publish success message if they uploaded the file successfully, tough only if the pages is published after uplaoding a file. I found the question linked below, I could figure out how to show a custom message but it is not a very satisfying solution. The wagtail version, I'am using is 4.22 customize-post-publish-flash-message-in-wagtail-cms @receiver(page_published, sender=Model) def process_uploaded_file(sender, instance, **kwargs): if instance.uploaded_file: process_data(instance.uploaded_file.path) instance.uploaded_file.delete(save=False) instance.uploaded_file = None instance.date = (date.today()) instance.save() I took the hook from the answer in the question linked above and changed it a bit.

My View is as follows: def download_rollback(request): serial = request.POST.get('serial') response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = 'attachment; filename="{}.csv"'.format(serial) writer = csv.writer(response) writer.writerow(['timestamp','serial','log']) queryset = ConfigLog.objects.filter(ser_no=serial).filter(log__contains='ROLLBACK') for obj in queryset: writer.writerow([obj.timestamp, obj.ser_no, obj.log]) return response and I have the following urls.py: urlpatterns = [ ... path('beaconing/download_rollback/', views.download_rollback,name='download_rollback'), ... ] I have followed various tutorials to try this - they all pointed to something like the above, but none works. -
Data in form is not showing in database. Only new line is appearing
I am doing project in django. It is voting system. I already designed webpage. But the problem is when I connected voting page to database it is not working properly. When i am voting and submitting the form. It is not displaying in database. Only entry is happening. Means there will be new line add in table but the data we entered in voting page is not showing. How can I solve this? I want to display voter name and the candidate name voter voted for in database. -
No data is sent when submitting the django form
I'm trying to create an Order object via ModelForm, but nothing comes out. Forms.py class OrderCreateForm(forms.ModelForm): user = forms.ModelChoiceField(queryset=get_user_model().objects.all(), widget=forms.HiddenInput()) is_payed = forms.BooleanField(required=False, widget=forms.HiddenInput()) status = forms.IntegerField(widget=forms.HiddenInput()) payed_at = forms.DateTimeField(widget=forms.HiddenInput(), required=False) price = forms.IntegerField(widget=forms.HiddenInput(), required=False) class Meta: model = m.OrderStorage fields = '__all__' Views class StartOrder(generic.CreateView): template_name = 'clientpart/order_create.html' success_url = reverse_lazy('order_list_tire') form_class = f.OrderCreateForm queryset = m.OrderStorage.objects.all() def get_form(self, form_class=None): if form_class is None: form_class = self.get_form_class() form = form_class(**self.get_form_kwargs()) if form.is_valid(): size = int(str(form.cleaned_data['size'])) period = int(str(form.cleaned_data['period'])) price = size*period form.fields['price'].queryset = int(price) return form def get_form_kwargs(self,): ret = super().get_form_kwargs() print(ret) ret['initial'] = { 'user': self.request.user.pk, 'status': OrderStatus.CREATE, } return ret According to my idea, the value is taken from the field and the price is created, then it is written to the dictionary, but for some reason it is not written to the dictionary. enter image description here How do I record an object price
