Django Asyc function execution
I am trying to execute the functions in async mode using Django DRF APIView, so that the API returns the response instantly. I am using Django 4.1.12, adrf for async View. Below is the code : import asyncio from asgiref.sync import sync_to_async from adrf.views import APIView def sensitive_sync_function(): count = 0 while True: count = count + 1 print("Running in Async mode !") time.sleep(1) if count == 10: print("Processing done !") break return None class AsyncGroupManagementView(APIView): async def get(self, request, format=None): async_function = sync_to_async(sensitive_sync_function) return Response(response, status=status.HTTP_200_OK, headers=headers) The Api call executes successfully and returns response, but I am not sure if the sensitive_sync_function() executed or not as I am not able to see any logs on terminal. Do I have to explicitly execute this task later ? My end goal is to run the function in async mode, so the API response is returned and the function keeps on executing in background. Is this the correct approach or should I use celery here ? Any AWS cloud based solution for this scenario are also welcomed ! -

How to enable right click in a new tab but normal clicking (left-click) redirects to new page using the same tab?
I am using a form in my project having multiple pages to fill information, these below are some of the items in my left side menu to switch to different pages while filling the form. So currently I am using the functionality to redirect the page on the same tab when clicking on any of these items. But when I right click, open in new window or new tab window doesn't appear. I want to enable open in a new tab only when right clicking on these items. <li id="arrival_button" class="nav-item w-100 side_bar_buttons"> <a onclick="save_and_redirect('mainform','arrival_information')" class="nav-link align-middle px-0 black_color"> <span class="ms-1 d-sm-inline">Arrival Information</span> </a </li> <li id="food_drinks_button" class="nav-item w-100 side_bar_buttons"> <a onclick="save_and_redirect('mainform', 'food_and_drinks');" class="nav-link align-middle px-0 black_color"> <span class="ms-1 d-sm-inline">Food & Drinks</span> </a> </li> <li id="guest_button" class="nav-item w-100 side_bar_buttons"> <a onclick="save_and_redirect('mainform', 'guest_req');" class="nav-link align-middle px-0 black_color"> <span class="ms-1 d-sm-inline">Guest Requirements</span> </a> </li> I already know about using target="_blank" with tags in Django but obviously like I already explained I dont want to use this functionality to always open them in a new tab only when I want to right click on them. -
Exploring the Replication of Odoo.sh Features and Building a Web Application (Django)
I'm interested in replicating the features of odoo.sh. Could anyone provide any valuable resources or links to assist in this endeavor? I've discovered a script that partially automates odoo.sh features, but I intend to create a comprehensive web application (using Python/Django) for this purpose. Is this feasible, and where should I begin? Is there a way to explore the source code of odoo.sh or gain insights into its architecture? Additionally, what other technology stack components should I be familiar with besides Python/Django, Docker, and basic cloud and system administration (e.g., Docker, AWS, etc.)? -

makemigrations - No changes detected - Django 4.2 only
Well, I was folloging Django Girls Tutorial but using django version 4.2 All was right until I need makemigrations when I created the model.

Django exception process in production mode

Nginx not working with Docker, Django and Gunicorn

Implementing Custom Groups and Permissions for Organization Members in Django
I'm working on a Django project where I need to implement a feature that allows each organization to create groups and assign custom permissions to the members of those groups. I want to ensure that organization administrators can create specific groups only for their organization and assign limited permissions related to the app's features. My "Organization" model is defined as follows: class Organization(models.Model): name = models.CharField(max_length=64) owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name='owner_organizations') slug = models.SlugField(unique=True) pic = models.ImageField(upload_to="organizations/pics/", default='organizations/pics/default.png') I also have an "OrganizationMember" model that links users to organizations: class OrganizationMember(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='organization_memberships') organization = models.ForeignKey(Organization, on_delete=models.CASCADE, related_name='members') # Here, I want to figure out how to manage groups and custom permissions for members of each organization. I noticed that Django provides default models for groups (django.contrib.auth.models.Group) and permissions (django.contrib.auth.models.Permission), but I'm not sure how to efficiently implement this feature. How can I proceed to allow administrators of each organization to create groups and assign custom permissions to the members of those groups?

Is it possible to make Django urlpatterns from a string?
I have a list of strings that is used to define navigation pane in a Django layout template.
