For the below sample schema # schema sameple class A(models.Model): n = models.ForeignKey(N, on_delete=models.CASCADE) d = models.ForeignKey(D, on_delete=models.PROTECT) class N(models.Model): id = models.AutoField(primary_key=True, editable=False) d = models.ForeignKey(D, on_delete=models.PROTECT) class D(models.Model): dsid = models.CharField(max_length=255, primary_key=True) class P(models.Model): id = models.AutoField(primary_key=True, editable=False) name = models.CharField(max_length=255) n = models.ForeignKey(N, on_delete=models.CASCADE) # raw query for the result I want # SELECT * # FROM P, N, A # WHERE (P.n_id = N.id # AND A.n_id = N.id # AND A.d_id = \'MY_DSID\' # AND P.name = \'MY_NAME\') What will be the queryset for this kinda raw query ? or is there a better way to do it ?

Django Python | Returning Render(request) and HTTP Reponse at the same time?
I'm trying to return a Render(request) and an HTTPReponse at the same time.. def home(request): db_userpull = user.objects.all().values_list('userkey', flat=True) http_resp = HttpResponse() http_resp.set_cookie('foo', 'bar') #return render(request, 'home.html', {"db":db_userpull}) #return http_resp return render(request, 'home.html', {"db":db_userpull, "sesstest":request.session['user_s_key']}) , http_resp Essentially the goal is, on load the page displays stuff from the database, and create a Cookie using an http response at the same time..

Django with CherryPy - ModuleNotFound errors
I found a gist that feasibly would allow me to integrate a CherryPy webserver into my program, and run a Django project via that CherryPy webserver. However I'm having some difficulties getting the thing to work properly.

designing an api to send same response code with different meaning
What is the proper way to design an API response that could have the same response status code but with a different meaning for the fronted to display? Here is my example: On our frontend, the user can submit an address and our backend validates the submitted address. It checks if the address is real. The response could be that the address does not exist, or that more information about the address is required to find it. In both scenarios the API returns 400. We want the frontend to be able to distinguish between the 2 because the type of alert we show the user changes color based on the bad request type. This is how we are currently achieving it: {"message": "Missing field in api", "type": 1}, 400 {"message": "123 Apple Wood Drive.", "type": 2}, 400 If the frontend gets the type 1, the color of the alert is red, while 2 it is orange. How can we improve this approach so that we arent instructing the client how to display? -
Updating the quantity of items in a shopping Cart not working properly
I am working on a Django E-commerce Project, and I have been following a tutorial and afterwards I decided to redo it on my own without the tutorial but I am stuck in a small issue which I don't understand the logic behind it. When a user adds an Item to Cart I want it to reflect on the no. of items that are showing on the navbar cart icon, but I am getting Invalid filter: 'cart_item_count' Here is my Item model.py class Item(models.Model): title = models.CharField(max_length=100) image = models.ImageField(blank=False, upload_to=upload_design_to) class OrderItem(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) ordered = models.BooleanField(default=False) item = models.ForeignKey(Item, on_delete=models.CASCADE) quantity = models.IntegerField(default=1) variation = models.ManyToManyField(Variation) The application name is store, so here is what I have been done in the tutorial Added a new folder in the app with the name of templatetags and inside the template tags folder created file called cart_template_tags and here is what is inside it: from django import template from store.models import Order register = template.Library() @register.filter def cart_item_count(user): if user.is_authenticated: qs = Order.objects.filter(user=user, ordered=False) if qs.exists(): return qs[0].items.count() return 0 My question is how do I fix this error and I want to understand behind the logic of having … -

How do I make my whitenoise static files show up?
Many solutions to this already on SO, but each one is different, and none work for me. I uploaded my Django/Whitenoise website to Heroku, and the static files stopped working, as usual. Collectstatic worked and saved them to /staticfiles, but the logo and few images I need won't show up on the website. Does anyone have a cure for this strain of the "Universal but poorly documented Django staticfiles error"? Filemap: sfl_website --website(app) ----website/static(contains my static files) --staticfiles(where collectstatic sends them) settings.py STATIC_URL = '/staticfiles/' STATIC_ROOT = '/Users/Lewis/Documents/sfl_website/staticfiles' STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' template code {% load static %} src="{% static "website/images/logo" %}" The logs say: "Not found: static/website/images/logo". Why is it looking there? Where does my code tell it to look? -

How to get user ID/name as variable in django-allauth
I'm trying to build a simple django API that uses django-allauth's Discord OAuth2 to log in. To generate API tokens, however, I would like to have the user's ID or username.

Django - ManyToMany - how to filter on parent's ManyToMany object
I have problems with writing a filter on my queryset models: class Order(models.Model): items = models.ManyToManyField(OrderLine) store = models.ForeignKey(Store, blank=True, null=True, on_delete=models.SET_NULL) class OrderLine(models.Model): orderItemId = models.IntegerField(blank=False, null=False, unique=True) quantity = models.IntegerField(blank=True, null=True) class Store(models.Model): storeName = models.CharField(max_length=200, blank=True, null=True) access_from_account = models.ManyToManyField(EDUser, blank=True) I have my queryset of EDUser "accounts" Now I want to select OrderLines that belongs to Order that are from Store that is visible by an account in access_from _account. So, for example: store_name_1 has access_from_account user_1, user_2 store_name_2 has access_from_account user_1 There at Orders that belongs to store_name_1. Those Orders have many OrderLines. I would like to select order_lines that should be accessible by user_1. Can I do it by: acounts is queryset of ['user_1'] lines = OrderLine.objects.filter(order__store__access_from_account__in=accounts)? I tried that, but I get some strange values... Any suggestion of how to do it properly? I would like to avoid making lists and iterate over them. Thanks in advance :) -
