Django static loaded but not used
Nginx web server serves static. Browser downloads static files but they don’t work. Why would that be?

Problems with Django URL routing
I'm building a website, to be used in dental practices, however I'm having trouble with the URL routing. I'm wanting af URL pattern like: Denthelp/kartotek/#nameofclinic#/opretpatient. My suggestion looks like this: urls.py: path('kartotek/<str:kl_id>/', views.kartotek, name="kartotek"), path('kartotek/<str:kl_id>/opretpatient/', views.opretpatient, name="opret_patient"), Views. py: def kartotek(request, kl_id): kliniknavn = Klinik.objects.get(navn=kl_id) E_patient = kliniknavn.patient_set.all() context = { 'kliniknavn':kliniknavn, 'E_patient':E_patient} return render(request,'DentHelp/kartotek.html', context ) def opretpatient(request, kl_id): kliniknavn = Klinik.objects.get(navn=kl_id) form = PatientForm() if request.method == 'POST': form = PatientForm(request.POST) if form.is_valid(): form.save() return redirect('kartotek/<str:kl_id>/') context = {'form':form, 'kliniknavn':kliniknavn} return render(request,'DentHelp/kartotek/<str:kl_id>/opretpatient.html', context) When running code I get an OSError for the last line of code shown here.

Django query annotate after filter doesn't work correctly
I have two models that are related using a m2m relationship through an intermediate model. The relation field is called participants. When I do this: chats = Chat.objects.annotate(Count("participants")).filter(participants=user) chats.get(pk=11).participants__count It will return 2; which is correct. But when I do this: chats = Chat.objects.filter(participants=user).annotate(Count("participants")) chats.get(pk=11).participants__count It will return 1. And not only for this object for all of the objects in the queryset. What's wrong? what am I doing wrong? I need to annotate a filtered queryset. -
How does "alternates" in the Django site framework work?
I am struggling to get the "alternates" attribute to work in the Django sitemap framework. class StaticViewSitemap(sitemaps.Sitemap): priority = 0.5 changefreq = 'daily' i18n = True alternates = True def items(self): return ['index', 'about'] def location(self, item): return reverse(item) The documentation appears to suggest the above i.e. setting i18n and alternates to True. But when I do that, my sitemap is literally a plain test string like this: http://127.0.0.1:8000/en/daily0.5http://127.0.0.1:8000/en/about/daily0.5http://127.0.0.1:8000/es/daily0.5http://127.0.0.1:8000/es/about/daily0.5 Whereas it should look like so: <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xhtml="http://www.w3.org/1999/xhtml"> <url> <loc>http://127.0.0.1:8000/</loc> <changefreq>daily</changefreq> <priority>0.5</priority> </url> <url> <loc>http://127.0.0.1:8000/about/</loc> <changefreq>daily</changefreq> <priority>0.5</priority> </url> </urlset> There are two issues: It doesn't have the correct formatting. What am I doing wrong here? I don't want the 'en' language prefix for the default language. How do I remove this? -
Submit form post from another view with input field
I am relatively new to Django and I'm making a small "social" project. It basically consists of user profiles, and on those profiles you can post "comments". I have a view that displays the comments each user has, and a separate view that allows you to post comments. This works as expected. The problem I am facing right now is the following. - I have an < input type=text > field in the view to view comments, and I want to be able to post a comment from there and have it saved in the database. I have tried grabbing the post kwargs in the form, but I couldn't get it to work correctly nonetheless have it save automatically. How can I get this done? Here is the code that I have so far. Comments view: class CommentsView(auth_mixins.LoginRequiredMixin, views.ListView): model = ProfileComments template_name = 'comments/comments_view.html' paginate_by = 5 def get_queryset(self): receiver = PROFILE_MODEL.objects.get(pk=self.kwargs['pk']) if receiver: return self.model.objects.filter(receiver=receiver) return None def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) receiver = PROFILE_MODEL.objects.get(pk=self.kwargs['pk']) if receiver: context.update({ 'receiver': receiver }) return context View to post comments: class CreateCommentView(auth_mixins.LoginRequiredMixin, views.CreateView): form_class = CommentsForm template_name = 'comments/post_comment.html' @staticmethod def get_profile_model_by_pk(pk): return PROFILE_MODEL.objects.get(pk=pk) def get_form_kwargs(self): kwargs = super().get_form_kwargs() kwargs['author'] … -

Django template language how to fix
Hi I'm trying to build a simple django app but I can't get index.html file to recognise the variables created in views.py. Nothing I do seems to work. Does it have to be configured somehow in settings.py perhaps? index.html: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <p>Hello world {{ name }}</p> </body> </html> views.py: from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): context = {'name' : 'Peter'} return render(request, 'index.html', context) urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index') ] Whatever I try, the browser just doesn't recognise anything in the {{}}. It just leaves it blank. I seem to have tried everything. Please help, I'm tearing my hair out. Thanks -

Can I write posts for a personal Django blog website in static html files?
I'm pretty new to Django and have been experimenting making my own personal blog. General question I get that I can specify my blog post structure in models.py and use the admin site to write my blogs. However, what if I want to write my blogs in raw HTML files stored in, e.g. my-website/blog/posts/<list-of-html-blogs> and then have those files uploaded into the data base and shown on the website. Is there are a standard way of doing this? My initial approach is to create a Python function that reads in the HTML files as strings and uploads those files into the database manually, i.e. using something like blog.models.Post(title=my_title, content=html_as_string). Whenever I'd write a new blog, I'd then call this function to upload a specific html file. However, I have found very little online about whether this is the correct approach. Django blog overview If helpful, I'm showing below what my blog's models.py and views.py currently looks like. models.py from django.db import models STATUS = ( (0, "draft"), (1, "published") ) class Post(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True, null=True) date = models.DateTimeField() content = models.TextField(blank=True) status = models.IntegerField(choices=STATUS, default=0) class Meta(object): ordering = ["-date"] def __str__(self): return self.title … -
About cleaning memory used in GPU with Tensorflow operation
Here is my installed environment, Cuda 10.0 Nvcc Ubuntu 20.04 Python 3.7 Tensorflow 2.0 GPU When I simply run a style transfer code like the code provided here https://www.tensorflow.org/tutorials/generative/style_transfer It runs well if the process is done, but when I try to use Django-q to run it. The GPU memory will be kept even after my style transfer task is done. I have tried the following methods to test if the GPU memory can be released but keep my Django-q working. I manually used the command 'kill -9 ' and restart the Django-q with the command, it worked I ran the commands in Method 1 programmatically, it released the GPU memory but the future style transfer job could no longer reach the GPU. I restarted the server, and used a script to init my Django-q again, it worked but it took time. I used the session cleared method of Tensorflow, but it did not allow my later style transfer job to utilize the GPU. I have the following questions, which will be greatly appreciated if they can also be answered, Why I ran the command programmatically, it cannot utilize GPU for my later style transfer jobs How I can release … -

How can I use an OR-clause with haystack along with a distance filter?
I've been using a distance filter using regular django query filters within an OR-clause: self.filter(Q(location__distance_lt=(geometry, LOCATION_WITHIN_D)) | ~Q(type=Event.IN_PERSON)) I want to do a similar filtering as part of a haystack query, using SQ (queryset = queryset.filter(SQ(location__distance_lt=(geometry, LOCATION_WITHIN_D)) | ~SQ(type=Event.IN_PERSON))) but instead I get back the error: not all arguments converted during string formatting - and that only happens with the distance_lt query part, not the ~SQ(type..) I'm able to do this distance filtering with my search query by using queryset = queryset.dwithin('location', geometry, LOCATION_WITHIN_D) but I want to be able to have that 'or' condition in this sub-clause. Is this even possible without resorting to raw querying? -

How to put a constraint using foreign key fields in Django?
Consider following models: class Model1: x = an integer y = an integer class Model2: f1 = models.ForeignKey(Model1) f2 = models.ForeignKey(Model1) Now, I want to put a constraint on model 2 such that no duplicate pairs of f1.x and f2.x get inserted in model 2. How should I achieve it? I will be populating model 2 using bulk_create so maybe customising clean() or save() won't work. I'm new to Django and not able to figure it out. Any help will be appreciated.
