Extract the textContent of an element using hyperscript
I have 2 elements in the DOM <script id="info-length-lower" type="application/json">6</script> <script id="info-length-upper" type="application/json">6</script> And I need to get these in some hyperscript on one of the form fields, but nothing seems to give me a value.

How can I get this information out using hyperscript? -

Django ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS settings not fully understood
My Django server is running on 127.0.0.1:8001. I use nginx to reverse proxy my django server to port 80. The nginx config looks like this: server { listen 80; location / { proxy_pass http://127.0.0.1:8001; } location /static { root STATIC_ROOT; } } I got confused when I try to understand ALLOWED_HOSTS and CSRF_TRUSTED_ORIGINS settings. These 2 settings all don't work: ALLOWED_HOSTS = ["example.com"] CSRF_TRUSTED_ORIGINS = ["https://example.com"] Or ALLOWED_HOSTS = ["127.0.0.1"] CSRF_TRUSTED_ORIGINS = ["http://127.0.0.1"] Only this works ALLOWED_HOSTS = ["127.0.0.1"] CSRF_TRUSTED_ORIGINS = ["https://example.com"] Can anybody explains why I need to set them differently? If possible, how does nginx reverse proxy work generally? -

is it safe to create django-allauth confirmation email table manually?
I am building a web app using Django, and I am using Django-Allauth for the authentication. Somehow when I was inspecting the database in mysql workbench I though a saw a duplicate table named account_EmailConfirmation and before I think about it I dropped the table and both of them dropped. Idk exactly know why they appeared as 2 tables and when I dropped one the other was deleted but anyway, i decided then to create the table again manually. operations = [ migrations.CreateModel( name='EmailConfirmation', fields=[ ('id', models.AutoField(primary_key=True, auto_created=True, serialize=False, verbose_name='ID')), ('created', models.DateTimeField(auto_now_add=True)), ('sent', models.DateTimeField(null=True, blank=True)), ('key', models.CharField(max_length=64, unique=True)), ('email_address_id', models.ForeignKey(to='account.EmailAddress', on_delete=models.CASCADE)), ], options={ 'db_table': 'account_emailconfirmation', }, ), ] My question is this: Is this safe and okay to do, or is it going to cause issues later on? -

Django and nginx connected via a bridge network.How to parse domain and pass it to the proxy_pass?
I am working on a multi tenant app. I have nginx as a rev-proxy When a tenant registers I create a docker image and name it based on his subdomain Lets call tenant1 t1 and tenant2 t2. So t1.localhost.web to should be routed to t1.web:8000 where t1 is extracted from url in nginx by regex and concatenated to ".web:8000" and it becomes t1.web:8000 and set to proxy_pass in nginx.conf These dockers containers also have a bridged network and they can be reached by their names. So if you bash into one of these containers you can ping or curl each other by their names it worksm so they are reachable by name curl http://t1.web:8000 actually works given if you are "bash"ed into nginx container this is my config file events { worker_connections 4096; ## Default: 1024 } http { # Redirect HTTP to HTTPS server { server_name ~^(?<subdomain>.+)\.app\.dev; listen 80; location / { set $domainweb "http://$subdomain.web:8000"; proxy_pass $domainweb; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } } } to debug I tried to exclude the subdomain variable and tried location / { set $domainweb "http://t1.web:8000"; proxy_pass $domainweb; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } that also did not work but when … -

"Waiting list" or delay when sending emails with Django and the win32 library
I have just discovered something in the provided code, and I would like to explain it to you. During my tests with the email sending using this code, everything seemed to work correctly, but a specific issue arose. Let's say I have three emails to send: email 1, email 2, and email 3. When I send email 1, the console returns a 200 OK status, but the email doesn't reach my inbox. Then, when I proceed to send email 2, the console again returns a 200 OK status, and although a new email appears in my inbox, it turns out to be email 1. After waiting several minutes without receiving any updates or new emails, I proceed to send email 3. At this point, the console once again shows a 200 OK status, and, surprisingly, I receive a new email in my inbox, but now it is email 2. ` class ApiSendMailCreateNewReporter(APIView): def get(self, request, id_headerRequest): try: # Obtener el objeto HeaderRequest o devolver un error 404 si no existe header_request = get_object_or_404(HeaderRequest, id=id_headerRequest) # Serializar el objeto HeaderRequest serializer_header_request = HeaderRequestSerializer(header_request) usuario_id = serializer_header_request.data['id_user_id'] require_date = serializer_header_request.data['require_date'] customer = serializer_header_request.data['customer'] # Obtener la instancia de Engineers con role='admin' o … -

I am programming a website in Django I want to put the Arabic language in my link, but when I make the link in Arabic and when I choose it, it takes me to the page page not found Note: This only happens on the hosting server, meaning it does not happen on localhost urls.py from django.urls import path, re_path from . import views urlpatterns = [ # pages path('',views.index,name='index'), path('الصفحة/',views.listArticle,name='listArticle'), path('TravelTips/',views.TravelTips,name='TravelTips'), # view article path('الصفحة/<str:slug_url>/', views.view_article, name='Page_Article'), path('TravelTips/<str:slug_url>/',views.view_article,name='Page_Article'), ,] I expected that the problem was in the slug, but it turned out that Django in general did not accept Arabic letters -
CDN imports for PDF.js viewer.html in Django templates
I am trying to add the PDF.js viewer as it appears in the official demo in an HTML iframe of my Django template. I do not want include any of the assets of PDF.js in my repository and I want all my script and stylesheet HTML tags to refer to a CDN resource. Since the documentation contains a note that users of the library should not just copy/paste the web/viewer.html, I have created my own modified version named custom_viewer.html, which includes a subset of the features of the official demo. The prebuilt version of the library includes the following four tags in the demo web/viewer.html: <link rel="resource" type="application/l10n" href="locale/locale.json"> <script src="../build/pdf.mjs" type="module"></script> <link rel="stylesheet" href="viewer.css"> <script src="viewer.mjs" type="module"></script> My question is what are the corresponding CDN links to get this working without downloading the PDF.js library on the server? I have managed to replace the pdf.mjs file reference with a CDN link. More specifically, I have verified that when I copy the prebuilt PDF.js (version 4.0.379) in my static folder and I modify the paths as follows: {% load static %} <link rel="resource" type="application/l10n" href="{% static 'my-django-app/pdfjs-4.0.379-dist/web/locale/locale.json' %}"> <script src="https://cdn.jsdelivr.net/npm/pdfjs-dist@4.0.379/build/pdf.mjs" type="module"></script> <link rel="stylesheet" href="{% static 'my-django-app/pdfjs-4.0.379/web/viewer.css' %}"> <script src="{% static … -
Django, Subquery, more than one row returned by a subquery used as an expression
Here is my model structure class ContentFlag(models.Model): user = models.ForeignKey( User, verbose_name="user", related_name="object_flags", on_delete=models.CASCADE, ) flag = models.CharField(max_length=30, db_index=True) content_type = models.ForeignKey( ContentType, on_delete=models.CASCADE ) object_id = models.PositiveIntegerField() content_object = GenericForeignKey("content_type", "object_id") class Article(models.Model): owner = models.ForeignKey( settings.AUTH_USER_MODEL, verbose_name=_("owner"), null=True, blank=True, editable=True, on_delete=models.SET_NULL, related_name="owned_pages", ) flags = GenericRelation(ContentFlag, related_query_name="%(class)s_flags") title = models.CharField(max_length=255) class User(index.Indexed, AbstractUser): email = EmailField(verbose_name="email", unique=True, null=True, blank=True) name = models.CharField( blank=True, max_length=100, ) flags = GenericRelation(to="core.ContentFlag") I need to calculate User rating based on Flags number. Here is what I do for that subquery_plus = ContentFlag.objects.filter( Q(article_flags__owner_id=OuterRef("id")), flag=LIKEDIT_FLAG, ).values("id") top_users = ( User.objects.annotate( rating_plus=Count(Subquery(subquery_plus)), ).order_by("-rating_plus") ) But I got an error django.db.utils.ProgrammingError: more than one row returned by a subquery used as an expression How can I fix that?
