HTTP to HTTPS on NGINX Django server
I'm setting up a server on AWS from a Django project and my Nginx gives an error when trying to switch from HTTP to HTTPS. See my file: host = fantasy name server { listen 80; server_name host; return 301 https://host$request_uri; location = /favicon.ico { access_log off; log_not_found off; } location /staticfiles/ {alias /home/ubuntu/Filmes/staticfiles/;} location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } } Indeed when using the old domain over HTTP I am redirected to HTTPS but I get CONNECTION DENIED TO THIS DNS. -
Any idea why contexts are not showing in template?
So, I have this two function in my views.py class TheirDetailView(DetailView): model = List def listcomments(request): modell = Review.objects.all() return render(request, 'app/list_comment.html', {'model' : modell}) And have these two paths set in my apps urls path('list/<slug:slug>/', TheirDetailView.as_view(),name='list_detail'), path('comment/',views.listcomments, name='ListComments'), So I have two templates list_detail.html & list_comment.html Here in list_detail.html I have included list_comment.html (just the comment section is there in list_comment.html) In my list_detail.html .. ... .... <div class="commentss" id="comments-id"> <div class = "commentscarrier"> <div class="comment-contentsas comment-head"><p>Comments(3)</p></div> <hr> {% include "app/list_comment.html" %} ... ..

Reverse for 'password_change_done' not found. 'password_change_done' is not a valid view function or pattern name
I'm trying to use my custom template for password change. So I created its template (registration/password_change_done.html) and wrote the urls as below: from django.contrib.auth.views import PasswordChangeView, PasswordChangeDoneView app_name = "accounts" urlpatterns = [ path( "accounts/password_change/", PasswordChangeView.as_view( success_url=reverse_lazy("accounts:password_change_done") ), name="password_change" ), path( "accounts/password_change/done/", PasswordChangeDoneView.as_view( template_name="registration/password_change_done.html" ), name="password_change_done" ), ] Password change works fine but when its form is submitted, I get this error: NoReverseMatch at /accounts/password_change/ Reverse for 'password_change_done' not found. 'password_change_done' is not a valid view function or pattern name. I searched about it and it seems like it should work when I set PasswordChangeView's success_url. But it didn't make any difference. -
Apache/mod_wsgi/Django AJAX : 500 Internal Server Error: ModuleNotFoundError: No module named 'corsheaders'
Our issue is stemming from a Django project finding the corsheaders module running via Apache/WSGI. The code runs fine using the Django's local runserver but throws a 500 Internal Server Error when acccessed throught Apache (v.2.4.41). If we comment out the application and middleware in settings.py, the site and other code works fine (execpt the API functionality that needs corsheaders). We have exhausted the online resources we can find, so thank you in advance for the advice to uninstall and reinstall django-cors-headers in a variety of ways using pip. We do use several other modules that have been installed via this gateway with no issue. The best we can tell, the issue stems from the django wsgi not seeing the module. I included the relevant logs and settings below. I also noted the install locations for the corsheader module. Relevant Versions django-cors-headers==3.13.0 (installed at: /home/geekfest/.local/lib/python3.8/site-packages) django-cors-middleware==1.5.0 python==3.8.10 Django==4.1.2 Ubuntu==20.04.1 pythonpath: ['', '/usr/lib/python38.zip', '/usr/lib/python3.8', '/usr/lib/python3.8/lib-dynload', '/home/geekfest/.local/lib/python3.8/site-packages', '/usr/local/lib/python3.8/dist-packages', '/usr/lib/python3/dist-packages'] **settings.py** INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'corsheaders', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.humanize', 'stats', ] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django.middleware.common.CommonMiddleware', 'stats.middleware.EventData', ] ROOT_URLCONF = 'geekstats.urls' CORS_ORIGIN_ALLOW_ALL = True error.log [Fri Oct 07 11:01:49.957188 2022] [wsgi:error] [pid 11860] … -

Custom HTTP error pages in Django not working as intended
I want to make custom error pages for 404, 403, etc, but when I do anything mentioned in the documentation or any other forums/stackoverflow posts, it ignores the custom functions. I tried this already: How do I redirect errors like 404 or 500 or 403 to a custom error page in apache httpd? and many others. Am I doing something wrong? engine(custom app) \ views.py def permission_denied(request, exception): context = {'e':exception} return render(request, '403.html', context, status=403) core (main project) \ urls.py handler403 = 'engine.views.permission_denied' urlpatterns = [ path('admin/', admin.site.urls), [...] ...and it just shows the built-in error pages. Changing debug mode on or off doesn't change it. P.E.: when I pasted the views.py function, it threw an error saying it takes 2 arguments, one for request and one for the exception, so it knows that the function is there, but when I added it to the arguments, it still got ignored. Any advice appreciated! -
Django cached_property is NOT being cached
I have the following in my models: class Tag(models.Model): name = models.CharField(max_length=255) type = models.CharField(max_length=1) person = models.ForeignKey(People, on_delete=models.CASCADE) class People(models.Model): name = models.CharField(max_length=255) @cached_property def tags(self): return Tag.objects.filter(person=self, type="A") I would expect that when I do this: person = People.objects.get(pk=1) tags = person.tags That this would result in 1 db query - only getting the person from the database. However, it continuously results in 2 queries - the tags table is being consistently queried even though this is supposedly cached. What can cause this? Am I not using the cached_property right? The models are simplified to illustrate this case. -
Where do I install Apache2 in my existing Django Project
I have an existing Django project running on uWSGI, and I want to install apache2 to act as the web server. I found instructions online on how to do the installation - see link below. https://studygyaan.com/django/how-to-setup-django-applications-with-apache-and-mod-wsgi-on-ubuntu One thing the instructions does not mention is where do I run the installation. Do I run the installation in /root? Or somewhere else. Also, any feedback on the online instructions would be greatly appreciated. Thanks in advance -
Django Link to form with condition
On my base.html I have 2 links which lead to the same post_form.html and use the same forms.py. Link: <a class="list-group-item list-group-item-light" href="{% url 'post-create' %}">Submit</a> Problem is, I would like to hide/show part of the page depending on which link did user select. How can I do that? Below is script I use to hide a field, but I don't know which link did they use. (currently the links are the same, don't know what to add to make a change on the page 'post_form.html) <script type="text/javascript"> function on_load_1(){ document.getElementById('div_id_type').style.display = 'none';} on_load_1(); </script> -
Django, keep initial url path unchanged
I have a Django project with 5 apps. Basically, in the homepage there are 3 links. I'm still not in deployment so the base url is localhost:8000 (the homepage app is called homepage). After the user clicks in one of the 3 links I want the url to stay with that number, even after using different apps. Example of what I'm looking for: User clicks on link 1 and then -> localhost:8000/1. User clicks on link that directs to another app (called ros) -> localhost:8000/1/ros. And keep that one at the start of the url and only change if another of the 3 links in homepage is selected. Example of what I'm getting so far: User clicks on link 1 and then -> localhost:8000/ros/1 or localhost:8000/ros/2 or localhost:8000/ros/3 depending on the link clicked. The question is, how can I modify the homepage URL's and the app ROS url's so that the ROS url receive the link parameter (either a 1,2 or 3) + ROS.urls. HTML homepage code <li><a href="/" class="nav-link scrollto"><i class="bx bx-home"></i> <span>Inicio</span></a></li> <li><a href="1/ros/1" class="nav-link scrollto"><i class="bx bx-file-blank"></i> <span>ROS 1</span></a></li> <li><a href="2/ros/2" class="nav-link scrollto"><i class="bx bx-file-blank"></i> <span>ROS 2</span></a></li> <li><a href="3/ros/3" class="nav-link scrollto"><i class="bx bx-file-blank"></i> <span>ROS 3</span></a></li> Homepage URL … -

Question about Django rest framework Serializers and Views working principles
I'm trying to build REST api with Django Rest Framework and kind a having diffuculty to understand how things connected each other in terms of when we need to use the custom functions. I have views.py like this class myAPIView(viewsets.ModelViewSet): queryset = myTable.objects.all() serializer_class = mySerializer this is my serializer.py class myserializer(serializers.ModelSerializer): class Meta: model = myTable fields = "__all__" def create(self, validated_data): #doing some operation here and save validated data def update(self, instance, validated_data): #doing some operation here and save validated data I want to add some custom function to do let's say sending emails with processed data. so when I add my_email_sender function to nothing happens (nothing prints to terminal). class myAPIView(viewsets.ModelViewSet): queryset = myTable.objects.all() serializer_class = mySerializer def my_email_func(): print("Hey I'm email function") my_email_sender() OTH, when do do this inside of the serializer its printing to the screen. I actually really don't know this my_email_func should be inside of views.py some sort of CRUD operation function like def create(), def update() etc.. I also don't know why we cannot call it from views.py ? Thank for your answer in advance! -

Modeling a messaging mechanism in Django
Using the m2m relationship (the 'watchers' field) in the models below and the default User model I'm able to keep track of what specific user tracks what specific items. Need a little help please with modelling the event of item(s) price change upon a periodic hourly check.

How do I go about figuring out which of these items should be in the notification msg (nevermind if it's email or something else) to each user?
