Django postgres migration issues when adding fields to existing models
I currently have a project in development. When trying to add new fields to existing models I am having issues with migrations which is causing me to worry about data loss. The errors I'm getting is that it says the fields don't exist when I can clearly see in the latest migrations file it has been added. I have never had this issue before when adding new fields and then pushing to the remote repository and then pulling it into production where I would then do the migrations. -
I need to prevent showing previous pages from my django app
Even after I logged out I'm still able to see my previous pages how to prevent the browser from showing this? I tried this piece of JavaScript code . Note: I used template inheriting and templates statically imported. function preventBack() { history.pushState(null, null, location.href); window.onpopstate = function () { history.go(1); console.log("worked") }; } window.onload = function() { preventBack(); console.log("worked call ") }; when I tried this "console showed worked call" but the 'worked' is not yet printed in console means wins=down.onpopState not worked what's the cause of this problem. I'm quiet new in Django feels like I tarped here!! -

How can I deploy an app on Heroku that is not located in the root directory?
I've got a project that has a directory structure as such: ├── backend │ ├── backend-files.py │ └── procfile ├── docker-compose.yml └── frontend I want to be able to deploy the Python backend (Django) on Heroku. As you can see it is located in it's own directory. However, Heroku does not allow me to specify a subdirectory when pointing to a github repo. This means that I would need my backend code to be at the root level in order to use their CD pipeline features. Does anyone know of a way to modify my configuration in Heroku so that I can keep the directory structure as is? -

I’m developing a django project and my veiws are function based and using django-allauth for authentication.

Custom OrderingFilter Django REST + Vue
I'm working on backend part of project (Django REST). I have a task - to do sorting for the front (Vue). The frontend sends a key for sorting and a parameter for sorting. Example: GET /api/v1/stocks/?sort_key=FBS&sort_type=ascending GET /api/v1/stocks/?sort_key=FBS&sort_type=descending I guess it can be done with OrderingFilter and DjangoFilterBackend. Any suggestions will be helpful. my models.py class Stock(models.Model): class Meta: verbose_name_plural = "Stocks" verbose_name = "Stock" ordering = ("-present_fbs",) store = models.ForeignKey(Store, on_delete=models.CASCADE, null=True, verbose_name="Store") fbs = models.PositiveIntegerField(default=0, verbose_name="FBS") my views.py class StocksApi(ListModelMixin, GenericViewSet): serializer_class = StocksSerializer permission_classes = (IsAuthenticated,) pagination_class = StocksDefaultPagination def get_queryset(self): return Stock.objects.filter(store__user_id=self.request.user.pk).order_by("-fbs") -

decode PDF from Django BinaryField using Angular / Typescript

Write uploaded file by chunks in an async context
I have a Python async function receiving a django.core.files.uploadedfile.TemporaryUploadedFile from an Django API endpoint, as well as from a Django form. Once this function is launched, it needs to write the file, and since the files are larges Django suggests to use UploadedFile.chunks() method to do so. So I have a classical sync method to write the file by chunks to a destination path, looking like this: from pathlib import Path from django.core.files.uploadedfile import TemporaryUploadedFile def write_file(file: TemporaryUploadedFile, destination: Path) -> None: with open(destination, "wb+") as out: for chunk in file.chunks(): out.write(chunk) As said, it is called from an async context, using asgiref.sync.sync_to_async. The main function logic looks like this: from asgiref.sync import sync_to_async from pathlib import Path from django.core.files.uploadedfile import TemporaryUploadedFile async def process_submission(file: TemporaryUploadedFile) -> None: ... do stuff ... await sync_to_async(write_file)(file=file, destination=Path("/my_path.mp4")) ... do other stuff ... ...but I get the error ValueError: read of closed file. I believe it might be related to the fact that the file is a stream, but I'm not really sure on what's happening. Any idea on why and how to solve that? -

Django using prefetch_related to reduce queries
I am trying to understand how I can improve the following query: class PDFUploadRequestViewSet(viewsets.ModelViewSet): def get_queryset(self): project_id = self.request.META.get('HTTP_PROJECT_ID', None) if project_id: return PDFUploadRequest.objects.filter(project_id=project_id) else: return PDFUploadRequest.objects.all() def get_serializer_class(self): if self.action == 'list': return PDFUploadRequestListSerializer else: return self.serializer_class The issue is that the more PDFPageImage objects are in the DB then it creates separate query for each of them thus slowing down the request. If there is only one value if PDFPageImage related to given PDFUploadRequest then its pretty fast, but for each additional value it is producing extra query and after doing some research I found out that prefetch_related might somehow help with this, but I have not been able to figure out how to use it with my models. This is how the model for PDFUploadRequest looks like: class PDFUploadRequest(models.Model, BaseStatusClass): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) file = models.FileField(upload_to='uploaded_pdf') file_name = models.CharField(max_length=255) status = models.CharField( max_length=50, choices=BaseStatusClass.PDF_STATUS_CHOICES, default=BaseStatusClass.UPLOADED, ) completed = models.DateTimeField(null=True) processing_started = models.DateTimeField(null=True) text = models.TextField(default=None, null=True, blank=True) owner = models.ForeignKey(User, related_name='pdf_requests', on_delete=models.PROTECT, null=True, default=None) project = models.ForeignKey(Project, related_name='pdf_requests', on_delete=models.PROTECT, null=True, default=None) class Meta: ordering = ['-created'] def no_of_pages(self): return self.pdf_page_images.count() def time_taken(self): if self.completed and self.processing_started: return self.completed - self.processing_started And this is the related … -
