Updates to admin.py not reflected in the django admin page
I'm building a django app and the django admin page doesn't seem to be reflecting the changes I make to admin.py. For example if I want to exclude some fields, or customizing the admin change list, nothing changes in the actual page. The only thing that seems to be reflected properly is the fact that I can register the models, and they will show up. Here's my admin.py from django.contrib import admin from .models import Form, Biuletyn, Ogloszenie, Album class FormAdmin(admin.ModelAdmin): exclude = ('img',) class BiuletynAdmin(admin.ModelAdmin): list_display = ('name', 'date') class OgloszenieAdmin(admin.ModelAdmin): fields = ('name', 'date', 'upload') admin.site.register(Form) admin.site.register(Biuletyn) admin.site.register(Ogloszenie) admin.site.register(Album) P.S. Please ignore the weird model names. The site is actually in a different language :D -
passing data from django view context dictionary to react components
I am trying to create a Django and React full stack web app and using django rest framework to create apis and it is really easy to work with these two when it comes to send data but for login and logout system it is becoming really messy to work with as we cannot get the request.user from a normal fetch request from react. and also passing data from a view context dictionary to react also getting too much difficult for me. I have a view to render index.html whose control is taken over by react and I want to send that if user is authenticated or not to my react component how can I do that? Here is how my view is looking. ```def index(request): authenticated = False if request.user.is_authenticated: authenticated = True context = { 'authenticated':authenticated } return render(request,'index.html',context)``` I want to pass authenticated to react component how can I do it? I have passed it to normal js on index.html but don't know how to pass it to react component. Here is how my index.html looks like. ```<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <link rel="icon" href="%PUBLIC_URL%/favicon.ico" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <meta name="theme-color" content="#000000" … -

Django - How can add multiple forms according to input enter number
I have an input field where the will customer add a number for buy membership then will get forms according to numbers 1,2, or 5 then will show 1,2, or 5 forms with input fields in which will add data. For example: customer will come to the site and click on buy membership the first page will How many Memberships do you want to buy? ==> input Field in which will add 1,2, or 5 based on how many members enter a show a page to collect information of members I have reached the multiple forms adding by the user with the button.

Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'NoneType'>` Error 504
I am trying to set up my e-commerce store, which works perfectly fine on the local machine, but when I tried to deploy it to VPS and try to send email or perform any other POST action I get ERROR 504 (Gateway Time-out).

In th esettings below I am trying to run Vue.js Frontend, Django Backend and API on the same ip and port, which works fine (I can even register a user). But when I try top POST in returns Error 504.

Call UpdateView without going to the UpdateView page in Django
I am looking for the best way to make an updateable list from model objects in Django. Let's say that I have a models.py: class Machine(models.Model): machine = models.CharField(max_length=10, blank=True) currently_running = models.CharField(max_length=30, blank=True) and I have a views.py that shows the objects from that model: class MachineView(ListView): model = Machine fields = ['machine', 'currently_running'] template_name = 'viewer/machine_view.html' class MachineUpdateView(UpdateView): model = Machine fields = ['currently_running'] template_name = 'viewer/machine_update_view.html' Then I have a template, machine_view.html: ... <table> <tr> <th>Machine</th> <th>Part Running</th> <th></th> </tr> {% for machine in object_list %} <tr> <td>{{machine.machine}}</td> <td>{{machine.currently_running}}</td> <td> <a href="{% url 'machine_update_view' pk=machine.pk %}">Change</a> </td> </tr> {% endfor %} </table> ... and machine_update_view.html: ... <form method="post">{% csrf_token %} {{ form.as_p }} <input type="submit" value="Update"> </form> ... This currently takes the user to the update page where they input a single parameter, and press update again. Would it be possible to do this with just passed parameters automatically? So instead of going to an update page, they just make the change they would like to, and then send the update request directly. Then refresh the page so they can see their update they made. Can this be done? Edit: For clarity of what I would want … -
Not able to inspect django migrations from test but working from django command
I want to be able to inspect Django migrations within a test (so I can check basic sanity before running more expansive tests). For doing that I was able to do the following in a django command: from django.core.management.base import BaseCommand from django.db.migrations.loader import MigrationLoader class Command(BaseCommand): help = "Check migrations" def handle(self, *args, **options): self.migration_loader = MigrationLoader(None) self.migration_loader.build_graph() for root_node in self.migration_loader.graph.root_nodes(): print(app_name, root_node[0]) But when I translate that into a test (using pytest): from django.db.migrations.loader import MigrationLoader def test_multiple_leaf_nodes_in_migration_graph(): migration_loader = MigrationLoader(None) migration_loader.build_graph() for root_node in migration_loader.graph.root_nodes(): print(app_name, root_node[0]) Then the graph (root nodes) returns an empty list. Is there anything I need to do so I can "see" migrations within the test ? -
Django - Queryset results not displaying in template
I am learning Django and building an inventory app for a laboratory. I already have data in all my models, and now I want to search the database based on some criteria and display the results in a table. First I ask the user to input the search terms (that part works), then I query the db (that also works) but when it's time to display results all I get is an empty template. No error messages.

How to get Django queryset in Ajax conform data structure?
I have a view that transforms a queryset into a list which is then returned as JSON for further use of Ajax on client-side. However, since I need multiple fields (namely poller_text and poller_id) of each object Ajax requires the following structure: [ { "value": "poller_text", "label": "poller_text", "url": "poller_id" }, { "value": "poller_text", "label": "poller_text", "url": "poller_id" }, ] Right now this is what I get using the view below: ["poller_text", "poller_id", "poller_text", "poller_id"] # View def autocomplete(request): if 'term' in request.GET: qs = Poller.objects.filter(poller_text__icontains=request.GET.get('term')) pollers = list() for poller in qs: pollers.append(poller.poller_text) pollers.append(poller.poller_id) return JsonResponse(pollers, safe=False) else: pass I think the append loop is badly designed, but how to get the required structure? -
How to avoid users creating new Websockets/Rooms using Django Channels?
I'm basically following this tutorial: https://channels.readthedocs.io/en/stable/tutorial/part_3.html In this simple example, everyone can create and join different rooms. I want to make an webapp where there are existing rooms defined, so I don't want users going around creating random websockets. What would be the best way to achieve this safely? Does simply doing the logic in yours views work? That is, only return a render if it matches a room (url pattern) that's allowed. Is this good enough, or can people bypass this? Could someone for example tamper with the javascript code and create websockets anyway? If I look at the code in front end: # const chatSocket = new WebSocket( 'ws://' + window.location.host + '/ws/chat/' + roomName + '/' ); And backend: # def connect(self): self.room_name = self.scope['url_route']['kwargs']['room_name'] self.room_group_name = 'chat_%s' % self.room_name async_to_sync(self.channel_layer.group_add)( self.room_group_name, self.channel_name ) self.accept() It looks to me like people can just temper with the code and make groups on the server unintended? -

Handling day objects and date in string format
Please bear with me as I try my best to explain the problem. As the title states I am struggling to find a solution for this problem I have whereby days (Mon, Tue, Wed, etc) are objects, and I have dates (DD/MM/YY) in string format. What I would like to do is for a specific date to be able to identify the corresponding day object. For example, say if I have a chosen date 25/09/21 - which is a Saturday, and I have an array of day objects Mon (id 001) Tue (id 002) Wed (id 003) Thu (id 004) Fri (id 005) Sat (id 006) Sun (id 007) How can I get it so that the date is able to identify the correct day? To add to the problem, say again I have a chosen date 25/09/21 - Saturday, and I have an array of Saturday-only day objects Sat (id 010) Sat (id 017) Sat (id 003) What would I need to do in order for the date to be able to identify the 'correct' Sat object? Thanks in advance. -
how can i download the exact uploaded file in django..?

Djando Form's input fields are only shown after submitting invalid form
I am working on an educational Auctions app which should allow Users to place a bid and add comments to an existing auction listing. I want to implement comments as a CommentForm and include this form's snippet comment_add.html into the view_listing.html template, which in turn extends base layout.html. But the view_listing.html initially doesn't show input field from comment_add.html. The "textarea" input field shows only after pressing "submit button" as it is a required field. Expected result: screenshot of the "Comment" area of the page Actual result: screenshot of the "Comment" area of the page Result after pressing "Commit": screenshot of the "Comment" area of the page Of course implementing comment input field as an <input> in comment_add.html works. I was guessing the problem has something to do with the same context being passed to view_listing.html from other views (context variable name is the same for all views - "listing"). But so far I wasn't able to figure out the decision. views.py def comment_add(request, listing_id): listing = Listing.objects.get(pk=listing_id) if request.method == "POST": form = CommentForm(request.POST) if form.is_valid(): text = form.cleaned_data["text"] author = User.objects.get(pk=request.user.id) comment = Comment(text=text, author=author) comment.save() context = {"form": form, "listing": listing} return HttpResponseRedirect(reverse("auctions:listing", args=(listing.id,))) else: context = {"form": … -
