Django Admin Sidebar Bug
I've been having this weird issue with my Django site for a few weeks now that I can't quite figure out. Whenever I go to the admin page on my local machine (DEBUG=True) it's completely unusable because the sidebar is filling the entire screen as pictured below: This began happening when I upgraded to Django 3.1 if that matters (this project started on 2.1) This does not happen on my live/production site. When I switch DEBUG=False on my local machine it works as expected as well however I can't figure out for the life of me what's causing this. I've tried other browsers as well to no avail. -
Django: issue with template path for tenant
I have an app where depending on its category, a tenant is either directed to the app (and templates) at /dashboard/templates/dashboard or /dashboard2/templates/dashboard2. somehow, for dashboard2, the app is not found by django and it tries to find those templates under dashboard. here is a dashboard2/views.py @method_decorator(login_required, name='dispatch') class SupplierPage2(LoginRequiredMixin,APIView): def get(self, request, *args, **kwargs): query = request.GET.get('search_ress', None) print(query) context = {} #if query and request.method == 'GET': Supplier = supplier2.objects.filter(supplier = query) print(Supplier) labels = Item2.objects.filter(fournisseur = query).values_list('reference', flat=True)[:10] print(labels) default_items = Item2.objects.filter(fournisseur = query).values_list('number_of_sales', flat=True)[:10] print(default_items) label1s = Item2.objects.filter(fournisseur = query).values_list('reference', flat=True)[:10] print(label1s) default_item1s = Item2.objects.filter(fournisseur = query).values_list('number_of_orders_placed', flat=True)[:10] print(default_item1s) context.update({'Supplier' : Supplier, 'labels':labels, 'default_items':default_items,'label1s':label1s, 'default_item1s':default_item1s}) return render(request, 'Supplier2.html',context) and the error: TemplateDoesNotExist at /Supplier2.html Supplier2.html Request Method: GET Request URL: https://uname.website.net/Supplier2.html Django Version: 3.0.5 Exception Type: TemplateDoesNotExist Exception Value: Supplier2.html and the traceback: Template-loader postmortem Django tried loading these templates, in this order: Using engine django: django.template.loaders.filesystem.Loader: /home/ubuntu/website/dashboard/templates/dashboard/dashboard2/templates/dashboard2/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/website/customers/templates/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/django/contrib/auth/templates/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/website/dashboard/templates/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/website/tenantlogin/templates/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/website/uploadfiles/templates/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/django_tenants/templates/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/rest_framework/templates/Supplier2.html (Source does not exist) django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/django_tables2/templates/Supplier2.html … -

Using django objects.filter to filter on db with a datetime field but for date only and based on local time not UTC
I have a model that created a simple table, the checkin date and the checkout date are datetime fields that store items in UTC format from a django form. I want to send a report later on of everyone who checked in or checked out for the whole day (Send out the report like at 11:55pm local time) the problem is that a full day local time is two days in UTC (there is a roll over) not sure how to handle that nad get the data I need using django: What I am trying to do: def select_users(): currentTime = timezone.now() loggedIn = OnSiteLog.objects.filter(autoCheckin=False, checkIn = currentTime, checkOut = currentTime).count() #just a countfor now to test print(str(loggedIn)) The problem is two fold: I believe that timezon.now() is getting a time also of like midnight. So my equals will fail. I really want to filter on day only and ignore time stamp. (Without changing the model though) I want that data still just not for this report. I had something almost similar working in SQLite where I could cast the field to just a DATE not sure how to do that in django. Then the second issue is that 5am … -

How can I upload profile picture in user extended model in Django
I am not getting any error while uploading cover image to the Django's User extended model but I cannot see what is wrong I'm doing because it's not giving any error and not even updating my model.

The order of inherited classes matters in Python?
I came across this error in my django application after hitting submit on a create or edit form: No URL to redirect to. Either provide a url or define a get_absolute_url method on the Model.. This was confusing because I have a get_success_url passed down through inheritance. To be clear, I have found the issue, but have no earthly idea why my solution worked. Here was the code causing the error inside .../views.py: class FormViews(): model = Ticket form_class = TicketForm def get_success_url(self): return reverse('tickets:index') class TicketCreate(CreateView, FormViews): template_name = 'tickets/ticket_create_form.html' model = Ticket form_class = TicketForm class TicketUpdate(UpdateView, FormViews): model = Ticket form_class = TicketForm template_name_suffix = '_update_form' I created the FormViews class so there would not be any repeated code for the model, form_class, and get_success_url. I was able to resolve this error by switching the parameters in my function definitions: class TicketCreate(CreateView, FormViews) became class TicketCreate(FormViews, CreateView) class TicketUpdate(UpdateView, FormViews) became class TicketUpdate(FormViews, UpdateView) This fixed it. Now I redirect to the index page without any issues. Why is it that the get_success_url is recognized after switching the listed parent classes? I would have thought that the attributes and functions are inherited and recognized by Django regardless … -

Django TypeError Field 'id' expected a number but got <class 'account.models.User'>
Error: TypeError: Field 'id' expected a number but got <class 'account.models.User'>. I have been reading the authentication documentation and I keep getting that error. I have tried a few different permutations of this but I'm really not sure what is going wrong other than its obviously a type error. The end goal is to just return the 'id' and 'email' of the newly created user, along with the token, I haven't been able to test the token returning yet, because of this error, but I imagine it should be good. What is working though is it is successfully posting a new user to the database with a token in another table with a matching key and now I have about 50 users from just testing and messing around. Side note I have overridden the default User Django sets you up with, but I followed the documentation so that code should be solid, but if need I can obviously post it Views.py from rest_framework import status from .models import User from .serializers import UserSerializer, RegisterSerializer from rest_framework.response import Response from rest_framework.decorators import api_view from rest_framework.authtoken.models import Token @api_view(['POST',]) def RegisterAPI(request): if request.method == 'POST': serializer = RegisterSerializer(data = request.data) if serializer.is_valid(raise_exception=True): … -
