How do I avoid django URL KeyError but keep my site's URL struture?
I started a Django web app with only one "food" app/section that leads to the food app URLs so my base url.py looks similar to this. urlpatterns = [ path('admin/', admin.site.urls), path('', home_view, name='home'), path('', include('food.urls')), ] Now I want to add/include a new "water" section for the water app urls.py similar to this urlpatterns = [ path('admin/', admin.site.urls), path('', home_view, name='home'), path('', include('food.urls')), path('', include('water.urls')), ] However, when I click on the water URLs I get a KeyError as the water URLs are being applied to the food.urls. My web app is already in production and I don't want to change the URL structure as this is bad for SEO. Therefore, what is the best solution to keep the current URL structure for both the food.urls and water.urls? For example, mysite.com/a-food-url and mysite.com/a-water-url. -
How can I use django-filter's DateTimeFromToRangeFilter with Graphene?
I'm attempting to use an instance of django-filter's DateTimeFromToRangeFilter in conjunction with a custom FilterSet. However, this does not work when I attempt to do the following: class CustomFilterSet(FilterSet): modified = django_filters.IsoDateTimeFromToRangeFilter() class Meta: fields = "__all__" model = Custom This does not result in additional fields or annotations being created, like I'd expect based on the docs. Something like: f = F({'modified_after': '...', 'modified_before': '...'}) If I inspect the single field (modified) which has been added to my DjangoFilterConnectionField, I see the following: {'creation_counter': 395, 'name': None, '_type': <String meta=<ScalarOptions name='String'>>, 'default_value': Undefined, 'description': None, 'deprecation_reason': None} So, how do I configure this filter such that I can write a query like the following? query { allTheSmallThings( modified_before: "2023-09-26 17:21:22.921692+00:00" ) { edges { node { id } } } } -

Connecting a Docker-ized Django app to local Postgresql database
For deployment purposes, I have set up my Django app in a Docker container. The setup works, and I am able to serve it using Gunicorn and Apache. However, I can't seem to access my Postgresql database anymore. This database is running locally, and I have no problem accessing it when launching my Django app from outside the container. But when I launch my app from inside the Docker container, all I get is this error: django.db.utils.OperationalError: connection to server at "127.0.0.1", port 5433 failed: Connection refused Is the server running on that host and accepting TCP/IP connections? Clearly I am not the first one having trouble with this. I have made sure that Postgresql is listening to external adresses, as stated here, so this shouldn't be a problem. I have also tried playing around with my Docker compose configuration file. Using network_mode=host is not compatible with port bindings. Back in network_mode=bridge, I have also tried as accepted here : extra_hosts: - "host.docker.internal:host-gateway" But it does not change anything, nor does replacing 127.0.0.1 with 172.17.0.0 in my Django .env file. I am a bit at a loss here, so any insight would be appreciated. I have to say that I … -

Django LoginRequiredMiddleware continuingly requests reload on the login page

Django and Javascript: Multiple events fired with same button not working as expected
I have this ongoing issue with an eventlistener. I can't seem to delegate the proper way and I'm at my wits end with this issue. The user clicks on a delete button which will check the hidden delete checkbox that the inlineformeset provides. This click of the delete button also adjusts the value of the TOTALFORMS in the management form. The box checks properly and the management form adjusts properly. However, when the user submits the form the delete checkbox that is checked submits false (unchecked) and the should-be deleted form is still there when I return back to the page. I have asked this question before and listened to the one suggestion. I also have tried countless things by adding options and rearranging code and making looping through the buttons. . . but nothing. Probably everything but the correct thing by now. {% load crispy_forms_tags %} {% load static %} {% block content %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" type="text/css" href="{% static 'css/availability_update_new.css' %}"> </head> <body> <input type="button" class="sun-not-available" value="Not Available Sunday" onclick="sunCheckOne(); sunHideShow()" id="sun-not-available"> <form id="all-add-form" method="POST" action="" enctype="multipart/form-data"> <div class="sun-hide" id="sun-hide-id"> <div class="sunday-all" id="sunday-all-id"> {% csrf_token %} <legend class="bottom mb-4">Profiles Info</legend> <div … -

Scheduled Notification in Django
I have a model in which there is a date and time field and the user detail. i want to send a notification to that user on the specified date and time.

Moreover if there are no notifications for next 10 days, the cron job will keep on running in the background. -
