How can I reach Django admin model stackedinlines in html tags?
I'm using stackedinline for for creating subtopic for each cancer type, in admin everything works fine, i can add subtopic for each type of cancer directly from cancer type creat/edit page, but I cant figure out how to display subtopic related to "parent" type in html template. P.S. I'm new in programming my models.py from django.db import models from ckeditor.fields import RichTextField class CancerType(models.Model): name = models.CharField(max_length=200, blank=False) image = models.ImageField(upload_to="static/assets/images/types") description = RichTextField(default="", blank=True, null=True) def __str__(self): return self.name class Meta: verbose_name = "Տեսակ" verbose_name_plural = "Տեսակներ" class SubTopic(models.Model): type = models.ForeignKey(CancerType, on_delete=models.CASCADE) title = models.CharField(max_length=200, blank=False) topic = RichTextField(blank=False, null=True) def __str__(self): return self.title class Meta: verbose_name = "Ենթաբաժին" verbose_name_plural = "Ենթաբաժիններ" admin.py rom django.contrib import admin from .models import CancerType, SubTopic admin.site.register(SubTopic) class SubTopicInline(admin.StackedInline): model = SubTopic extra = 0 class CancerTypeAdmin(admin.ModelAdmin): inlines = [SubTopicInline] admin.site.register(CancerType, CancerTypeAdmin) type.html {% extends 'base.html' %} {% load static %} {% block content %} <img src="{% url 'home' %}{{ cancertype.image }}"> <h4>{{ cancertype.name }}</h4> <br> {{ cancertype.description|safe }} <br> {% for subtopic in object_list %}} {% if subtopic.type %}} {{ subtopic.title }} <hr> {{ subtopic.body }} {% endif %} {% endfor %} {% endblock %} -

Python cli.py execution stuck: Unable to figure out the source
I'm trying tto deploy the following Django-rest api on gcp ubuntu 22.0.4 using python 3.9. https://github.com/OkunaOrg/okuna-api The enter setup is supposed to be done and get setup using a single command : python3.9 okuna-cli.py up-full The execution seems stuck at "Waiting for server to come up..." and doesn't proceed ahead. The setup should complete by stating "Okuna is live at "domain". Another important aspect of the setup is the 5 docker containers are running and working fine when i run the py file.

django.urls.base.get_script_prefix() returns incorrect prefix when executed by apache
Python-3.8/Django-3.2/Mezzanine-6.0 application tries to access incorrect pages when executed by apache. In standalone mode (python manage.py runserver) it creates correct address /admin/page_types/basicpage/2677/change/ whereas in apache mode it creates address /admin/page_types/basi/admin/pages/page/2677/change/ in the same place. It seems to be the get_script_prefix() function in django/urls/base.py that returns incorrect prefix when accessing page 2677 in apache mode. Also it seems to be running the same main thread all the time in apache mode. Could it be the main reason ?

How to fix too much time taken by python requests during get and post?
There is one website written in CakePhp and I am moving to Django. Some pages are making get/post request to another website to collect some information. CakePhp $socket = new HttpSocket(); $api_ret = $socket->get($url,$data,$this->header); Django import requests api_ret = requests.get(url,data,headers=self.header) Time taken by requests is too long compare to CakePhp. Is there anything I am doing wrong or Is there any other library that I can use ? Please Help. -
profile page of username 'admin' giving 404 error
My website is acting very weird for some reason. I have a profile page that displays information about an user. it takes username in url and pass it to view. It's working perfectly fine for all users, except for the super user 'admin'. For example, let's say there's an user with an username 'user01'. .../account/user01 will display profile page of 'user01'. But for some reason, .../account/admin leads to 404 error, and it specifies that it tried all urlpatterns including account/<str:username> [name='profile']. What makes this weirder is, when I do the exact same thing in incognito mode, .../account/admin works. Below are relevant codes: account/views.py def profile(request, username): try: user = User.objects.get(username=username) except User.DoesNotExist: raise Http404("User Does Not Exist!") return render(request, 'account/profile.html', {'user': user}) account/urls.py app_name = 'account' urlpatterns = [ path('login/', auth_views.LoginView.as_view(template_name='account/login.html'), name='login'), path('signup/', views.signup, name='signup'), path('<str:username>', views.profile, name='profile'), ] -

Why do webpages load so slowly the longer I use them?
I configured the webfront with Django and downloaded the modules using cdnjs. The contents composed inside are about 20 3d graphs of 120*50 size made with vis.js and 2d graphs made with plotly. I don't see this as the cause of the slowdown. Because when I first loaded the web page it took about 8 seconds and the next day it suddenly took about 1 minute to load. I don't know why there is such a difference. If anyone knows the cause, please let me know. When I checked with Google Developer Tools, it took a long time to load in JavaScript. When I loaded the webpage the previous day, the script that took 5 seconds to load took more than 1 minute the next day. I don't know where the web page takes to load, so I hope I get some hints. I want to know why the JavaScript loading is wrong with the time of the previous day and the next day. -

how to troubleshoot django 'internal server error'
a similar question was asked 7 years ago, but the answer/comments were not that helpful and maybe not current. I'm developing a new website and relatively new to django.

How to get the first record of a 1-N relationship from the main table with Django ORM?
I have a Users table which is FK to a table called Post. How can I get only the last Post that the user registered? The intention is to return a list of users with the last registered post, but when obtaining the users, if the user has 3 posts, the user is repeated 3 times. I'm interested in only having the user once. Is there an alternative that is not unique? class User(models.Model): name = models.CharField(max_length=50) class Post(models.Model): title = models.CharField(max_length=50) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='posts', related_query_name='posts') created = models.DateTimeField(default=timezone.now) class Meta: get_latest_by = 'created' ordering = ['-created']` I already tried with selected_related and prefetch_related, I keep getting multiple user registrations when they have multiple Posts. user = User.objects.select_related('posts').all().values_list('id', 'name', 'posts__title', 'posts__created') This does give me the answer I want, but when I change the created field to sort by date, I don't get the newest record, I always get the oldest. user = User.objects.select_related('posts').all().values_list('id', 'name', 'posts__title', 'posts__created').distinct('id') -

I need to get the query like this: session 1 ->> all GPSData of that session 1 session 2 ->> all GPSData of that session 2 So in the template I can render like this: For GPSData in session 1 do something For GPSData in session 2 do something etc. I tried to return multiple queries to the view but it didn't worked.

How can I add a Logout POST function to my HTML template that is written in vue?
I made my basic logout function here in my user's views. class SignOutView(View): def get(self, request): logout(request) return HttpResponseRedirect(reverse("home")) I called it in my user’s URLs. path( 'signout/', view=views.SignOutView.as_view(), name='signout', ), If I had a normal HTML template, I would call it normally with {% URL:users:logout %} But, what I have is an HTML from vue: const menu = `<MenuItems> <MenuItem> <a href="auth/logout"> Sign Out </a> </MenuItem> </MenuItems> ` My current logout is a href that makes a GET, but I want to change it, I want to add a POST here. I am looking for doing something like: <script type="text/javascript"> // get the anchor with dom and make the post </script> I am currently logging in and getting the csrf token. -
How to work with users on the Ory Hydra network in the Django system?
In my project, I use Django (as a backend development tool for multiple applications on the same network) and Ory Hydra (as a ready-made network for user authorization with the ability to use all applications from this network). Hydra is a tool thanks to which it is possible to work effectively with users, but it is important to transfer data about users locally from the applications that it uses. Below are the connection settings for the Django with Hydra add-on # Add import os to the beginning of the file import os import environ env = environ.Env() ... # We need to change a couple of settings here TEMPLATES ... # This tells django to use `mysite/templates` dir # for searching templates 'DIRS': [os.path.join(BASE_DIR, 'templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', # Add this line to enable context processor # and have variables like `login_url` available # in templates 'django_ory_auth.context.processor', ], }, But as far as I understand, the server simultaneously creates all users from Hydra in the Django database in all networks at the same time, which significantly loads the database, although it may never use this particular application. How can I configure the system …
