How to structure models in Django?
I'm working on a project using Python(3.7) and Django(3) in which I have to create some models to store reports. There are 4 different models to represents each type of report with only 2 common fields(RequestId, InstCode) but the rest of the fields are different. In the end, I have to display the 10 recent reports (mixed from all models) on the home page. Here's how I have implemented my models at the moment: From models.py: class DistributionReport(models.Model): RequestId = models.CharField(max_length=256, blank=False, default=0) InstCode = models.CharField(max_length=3, blank=False) Currency = models.CharField(max_length=3, blank=False) Denomination = models.IntegerField(blank=False, default=0)decimal_places=2) date = models.DateField(default=datetime.date.today) class Meta: verbose_name = 'Distribution Report' def __str__(self): return self.RequestId class ExpenditureReport(models.Model): RequestId = models.CharField(max_length=256, blank=False, default=0) InstCode = models.CharField(max_length=3, blank=False) StaffExpenditure = models.DecimalField(max_digits=12, decimal_places=2) Month = models.IntegerField(blank=False, default=0) Quarter = models.IntegerField(blank=False, default=0) Year = models.IntegerField(blank=False, default=0) class Meta: verbose_name = 'Expenditure Report' def __str__(self): return self.RequestId class StorageReport(models.Model): RequestId = models.CharField(max_length=256, blank=False, default=0) InstCode = models.CharField(max_length=3, blank=False) Currency = models.CharField(max_length=5, blank=False) Denomination = models.IntegerField(blank=False, default=0) date = models.DateField(default=datetime.date.today) class Meta: verbose_name = 'Processing Report' def __str__(self): return self.RequestId class AssetsReport(models.Model): RequestId = models.CharField(max_length=256, blank=False, default=0) InstCode = models.CharField(max_length=3, blank=False) AssetClassificationId = models.IntegerField(blank=False, default=0) VaultCapacity = models.DecimalField(max_digits=10, decimal_places=2) Year = models.IntegerField(blank=False, default=0) … -

Django Error: ValueError at /new_bid/1 Cannot assign "1": "Bid.listingid" must be a "Listings" instance
I am getting the error: ValueError at /new_bid/1 Cannot assign "1": "Bid.listingid" must be a "Listings" instance." I am still learning about Foreign Keys so I may have used it wrong? I'm also using 'listingid' in both the models 'Listings' and 'Bid.' I'm wondering if this is part of the issue, but it makes sense to have both to me. I am just learning about how 'self' works also, so I think part of the problem is in the Listings model at the very bottom: In the Listings model if I do: return self.last_bid I get the error "'>' not supported between instances of 'int' and 'Bid'" and if I keep it as is now, I get the error in the title of this Stack Overflow post. Any help is appreciated, I'm having trouble understanding the error. views.py def new_bid(request, listingid): if request.method == "POST": listing = Listings.objects.get(pk=listingid) response = redirect("listingpage", listingid=listingid) try: bid = int(request.POST["bid"]) except ValueError: response.set_cookie( "message", "Please input something before submitting the bid", max_age=3 ) return response if bid > listing.current_price(): response.set_cookie("message", "Your bid was accepted", max_age=3) Bid.objects.create(bid=bid, listingid=listingid, user=request.user) else: response.set_cookie( "message", "Your bid should be higher than the current bid", max_age=3 ) return response … -
Serialize Django Model and return GET Response

Django API responding slow and not returning Images on Heroku
I'm trying to host my Django Rest API to heroku for free so that my flutter mobile app can communicate with it. But the server response is extremely slow. Besides, it doesn’t returns images for user profile. Moreover, I'm using Image recognition at API to check image objects and return the checked image to client end. But the API fails to return the result. What could be the possible solution. I've applied migrations to server's end. N.B: it’s my University final project which needs to be hosted, so that I can show it for getting jobs. -

How to write data to a Django temp file?
Hello Community! I have a small application that allows you to download certain multimedia content from an HTML template. To save resources, I want this file to be stored only on the PC of the users who visit the eventual website, which is why I will use a temporary file NamedTemporaryFile that the FrameWork Django provides. Part of the code consists of: HTML TEMPLATE: ... <input type = "button" value = "Download" onclick = "window.open('download')"> ... urls.py: from django.urls import path from ProjectApp import views urlpatterns = [ ... path('download', views.download), ... ] views.py: import os from django.http import StreamingHttpResponse from wsgiref.util import FileWrapper from django.http import HttpResponse from django.core.files.temp import NamedTemporaryFile def download(request): newfile = NamedTemporaryFile (suffix='.txt', mode='w+b') file_path = os.path.join(MEDIA_ROOT, 'test.txt') # MEDIA_ROOT = os.path.join(BASE_DIR, 'media') filename = os.path.basename('archive_test.txt') chunk_size = 8192 response = StreamingHttpResponse( FileWrapper(newfile, chunk_size), content_type="application/octet-stream") response['Content-Length'] = os.path.getsize(file_path) response['Content-Disposition'] = f'attachment; filename={filename}' return response It should be noted that as I show it, it works as I wish, since a download dialog appears in the browser with the archive_test.txt file in a "starting" state.

How do I import a model from another app in Django?
So in my project book_letter, I have an app named contents. Inside it, I have a model named Book. As below. class Book(models.Model): objects = models.Manager() title = models.CharField(max_length = 30) author = models.CharField(max_length = 20) def __str__(self): return self.title And I have another app named recommendation, with a model named Recommendation. As below. from book_letter.contents.models import Book class Recommendation(models.Model): objects = models.Manager() source = models.ForeignKey("Book", related_name='book', on_delete=models.CASCADE) However, when I run python manage.py runserver, I get an error saying ModuleNotFoundError: No module named 'book_letter.contents' I don't see what I've done wrong. Any ideas? Thanks :) -
Django: Group by foreign key then get max id from group
I'm looking to grab the latest message in a conversation. My conversation model has attributes id (primary key) and user1 and user2, which are both foreign keys to a User model. My message model consists of a conversation(foreign key) and message primary key. These both just return only the very latest message. Message.objects.values('conversation').latest('id') Message.objects.order_by('conversation').latest('id') Any recommendations for getting this query?
