Websocket with Django Channels and IIS - No route found for path
I'm trying to deploy my Django application to my IIS server, but my websocket doesn't work when accessing via IIS, only locally. What did I miss?

Error in Django - [WinError 3] The system cannot find the path specified - Django
The problem is: Im trying to let users upload 5 images and on uploading I want them to change directory. So far my views.py class ProductCreateView(LoginRequiredMixin, CreateView): template_name = "product/add_product.html" success_url = reverse_lazy('home') form_class = ProductForm login_url = "/login/" # Save current user id as product_user_id in DB def form_valid(self, form, **kwargs): form.instance.product_user_id = self.request.user.id response = super().form_valid(form) id = form.instance.id picture_1 = form.instance.product_img_1 picture_2 = form.instance.product_img_2 picture_3 = form.instance.product_img_3 picture_4 = form.instance.product_img_4 picture_5 = form.instance.product_img_5 product_title = form.instance.product_title user = form.instance.product_user_id # Change directory new_directory = change_directory(id, product_title, user, picture_1, picture_2, picture_3, picture_4, picture_5) return new_directory utils.py def change_directory(id, product_title, user, picture_1, picture_2, picture_3, picture_4, picture_5): file_name = f"{id}-{product_title}-{product_title}-{user}" new_path = os.path.join(settings.MEDIA_ROOT, "product_images", file_name) if not os.path.exists(new_path): os.makedirs(new_path) picture_list = [picture_1, picture_2, picture_3, picture_4, picture_5] for i in picture_list: old_image_path = os.path.join(settings.MEDIA_ROOT, f"product_images/{i}") new_image_path = os.path.join(settings.MEDIA_ROOT, f"product_images/{file_name}/{i}") os.rename(old_image_path, new_image_path) return new_path The solution is not far away, but im out of ideas.

Multi Tenancy with Multiple Users Multi Multi Tenancy
Hello I am working on an a project where multi-tenancy is needed. In my case tenant is a company and with in that company you ll have multiple users. Lets say our company is called abc and our domain is domain.com. So abc.domain.com reaches the abc's resources. Now should each request check to see if subdomain is valid at application server level given that our dns is registered as *.domain.com (for simplicity lets forget about www as a domain) or should you explicitly register each subdomain (In this case is the registration of subdomains instant) IS this a common practice to actually write a script that adds the each subdomain explicitly. Starting a new tenant would take a lot longer I think. but if a wildchar is used you would need to make sure that that domain exists, so maybe a DB request is necessary or alternatively maybe you can attach the domain to your token or jwt or whatnot. How do one go about handling the domains ? -

Error when passing file content to Celery task: "Object of type InMemoryUploadedFile is not JSON serializable"
Description: I'm encountering an error when trying to pass file content directly to a Celery task in a Django application.

How to keep checkboxes selected and count after navigating to another page in using a select all function - ReactJS
I have a react app that contains a table that is populated with records from Django through rest-API.

Change a MultipleChoiceField to only be able to select one choice at a time
so I am currently working on a program in Django that uses MultipleChoiceFields, I only want to be able to select one choice at a time within the bounds of my code. How exactly would I be able to change my MultipleChoice field to accomplish this goal, and what attributes would I need to add? I have tried looking into documentation as well as some questions here as well for how one could modify the MultipleChoiceField function as seen here: https://www.geeksforgeeks.org/multiplechoicefield-django-forms/ https://groups.google.com/g/django-users/c/faCorI1i8VE?pli=1 Show multiple choices to admin in django But I have found no attributes to help me limit the size of the answers one could pick out to just one answer, or the answers are unrelated to the problem I am seeking to solve. Here is my code as well which also has the MultipleChoiceFields that I am trying to have select only one option: class ArdvarkForm(forms.ModelForm): class Meta: model = Course fields = ('is_done',) score_visual = forms.IntegerField(widget=forms.HiddenInput()) score_kinestetic = forms.IntegerField(widget=forms.HiddenInput()) score_auditory = forms.IntegerField(widget=forms.HiddenInput()) question1options = (('1', 'Read the instructions.'), ('2', 'Use the diagrams that explain the various stages, moves and strategies in the game.'), ('3', 'Watch others play the game before joining in.'), ('4', 'Listen to somebody explaining … -

How to resolve: Django, Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?

Choosing between Laravel and Django for a CRM project?
I need to build a CRM application for a medium-sized clothing factory that mainly produces t-shirts. The factory manages a large fabric storage with fabrics labeled by code (e.g., #001). Each fabric code corresponds to different models, and each model has various colors and materials. The goal is to store and display each fabric variety separately, along with showing the quantity of that model in the storage. Additionally, the factory frequently imports and exports fabrics, requiring tools for journaling these transactions. The application should log details such as the imported/exported model, quantity, color, and date. Currently, these activities are managed using Excel, and the aim is to create a user-friendly and comprehensive tool for these tasks. The application should include a search/filter tool to allow managers to easily find information. For instance, a manager might want to know which models and colors were imported/exported on a specific day or which fabric types were used for creating certain product models—an advanced search functionality is crucial. I've previously built something similar using Laravel but not at that scale (there was much less data). However, I'm uncertain if Laravel (with Postgres and NextJs) would be powerful enough for this specific application, considering the … -

Is there a way to get Django to reload after changes when using it with Docker?
I'm relatively new to Docker/deployment in general. I have a django app that utilizes rpy2 (not sure if relevant), that I have deployed using a docker container. However, I want to be able to continue developing the application and testing within the docker environment without having to spin the container up and down constantly. I read that using volumes could help to bring this functionality back, but I either have gotten the container working and don't see updates, or I get errors saying that manae.py can't be found.

Why is this local django DATABASES configuration not honored in django 5.0.1?
I'm using a local.py settings inclusion so the devs can use sqlite3 and deployed sites can use things like postgres. This is the local_py_example.py (using /tmp just for this repro): DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': '/tmp/db.sqlite3', } } The settings file imports this thus: import os import sys from django.utils.translation import gettext_lazy as _ from utilities.find_base_dir import find_base_dir # Build paths inside the project like this: BASE_DIR / 'subdir'. BASE_DIR = find_base_dir() sys.path.insert(0, f"{BASE_DIR.parent}") # will look for local.py in the parent directory try: # noinspection PyPackageRequirements,PyUnresolvedReferences from local import * except ImportError: from club_site.settings.local_py_example import * sys.path.pop(0) ...

I have a TextMessage model as you see: class TextMessaage(models.Model): id = models.UUIDField( _("Id"), primary_key=True, default=uuid.uuid4, editable=False, null=False, blank=False, ) created_at = models.DateTimeField(_("Created at"), auto_now_add=True) modified_at = models.DateTimeField(_("Modified at"), auto_now=True) sender = models.ForeignKey( User, on_delete=models.PROTECT, related_name="sent_messages", blank=False, null=False, verbose_name=_("Sender"), ) receiver = models.ForeignKey( User, on_delete=models.PROTECT, related_name="received_messages", blank=False, null=False, verbose_name=_("Receiver"), ) body = models.TextField( null=False, blank=False, validators=[MaxLengthValidator(4096)], verbose_name=_("Body"), ) What I am trying to do is to get last message of each conversation. I tried this: conversations = ( models.TextMessage.objects.filter(Q(sender=user) | Q(receiver=user)) .order_by( "sender__id", "receiver_id", "-modified_at", ) .distinct("sender__id", "receiver_id") ).all() The problem is that query that I have written will consider pair (sender=A, receiver=B) different from (sender=B, receiver=A) which is not I am looking for. I want these two pairs supposed the same since they share the same foreign keys regardless of their order. What should I do? To add more info, I am using Postgres by the way. -

How do I fix the module not found error in django
I created a django project which has 2 apps: Aceit and api, I am getting a module not found error when trying to make migrations or do anything that requires the manage.py file. I am using a virtual environment that uses python 3.10 it is worth noting that I had another project called AceIt(with a capital i as opposed to the one I have now), which I deleted. I am not sure if me deleting it is causing these problems but just thought to mention it. Below I have provided my file directory structure and stack trace of the error, if there is anything else I need to provide let me know. file directory structure: stack trace after calling python manage.py makemigrations: Traceback (most recent call last): File "C:\Users\mosta\Desktop\Desktop\Mostafa Azouz\Queen mary\Ace-It!\Code\Backend\api\manage.py", line 22, in <module> main() File "C:\Users\mosta\Desktop\Desktop\Mostafa Azouz\Queen mary\Ace-It!\Code\Backend\api\manage.py", line 18, in main execute_from_command_line(sys.argv) File "C:\Users\mosta\miniconda3\envs\Aceit\lib\site-packages\django\core\management\__init__.py", line 442, in execute_from_command_line utility.execute() File "C:\Users\mosta\miniconda3\envs\Aceit\lib\site-packages\django\core\management\__init__.py", line 416, in execute django.setup() File "C:\Users\mosta\miniconda3\envs\Aceit\lib\site-packages\django\__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Users\mosta\miniconda3\envs\Aceit\lib\site-packages\django\apps\registry.py", line 91, in populate app_config = AppConfig.create(entry) File "C:\Users\mosta\miniconda3\envs\Aceit\lib\site-packages\django\apps\config.py", line 193, in create import_module(entry) File "C:\Users\mosta\miniconda3\envs\Aceit\lib\importlib\__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File …
