Celery not running new task
I've readded an old Celery task to my Django app running on Heroku, but it's not being run by the worker. The task appears in the tasks when the worker starts, and I can see the scheduler sending it to the worker. However, it is never received by the worker. What can I do to troubleshoot this issue? Other tasks added are running fine and it runs fine on the staging server which is another instance on Heroku. I've tried restarting all the dynos and changing the name of the task and repushing it but that hasn't worked. -

Authenticating queries in Django Graphene custom nodes with filters and connections?
I'm working on a Django project using Graphene for GraphQL API implementation. I have a custom node called PoemNode which extends DjangoObjectType. I want to authenticate queries made to this node and also include filtering and pagination capabilities using filterset_class and connection_class respectively.

Increase Django CSRF tocken longevity
I get lots of Django CSRF errors due to timeout. In normal operations, the form submissions are OK. But, if I leave the page for a few hours and then submit it, it will fails with the Forbidden (403) CSRF verification failed. Request aborted screen. To overcome this issue, I added the following line to the settings.py : SESSION_COOKIE_AGE = 604800 # one week But a few hours leading to timeout means that this line has had no effect. I need CSRF tokens longevity be increased to a few days rather than minutes. How to achieve this? -

Django Celery running a function multiple times?

Arabic translations not displayed correctly in Django/Celery notification system
I'm currently working on a Django application that includes various functionalities, including notification delivery, in multiple languages. While most of the application works well with Arabic and other languages, I'm facing an issue with Arabic translations in certain parts of the application, including notifications. The Arabic translations are not being displayed correctly, while translations in other languages, such as English and French, work without any issues. Here are the details of my setup: The application uses Django and Celery for task management and background processing. I have added Arabic translations for different text elements in the respective translation files. The Arabic translations work fine in most parts of the application, including UI labels and content. However, when it comes to notifications, specifically in Arabic, the translations are not displayed correctly. Other functionalities, such as database operations, user management, and data processing, work as expected with the Arabic translations. I have ensured that the necessary translations are present, and the language preferences are correctly set for affected users. The issue seems to be specific to the notification tasks triggered by certain actions or events. It's puzzling because the Arabic translations work well in other areas of the application. I would greatly … -

I have one view with a chatbot on it, and it works fine. I added a second view and registered it in the urls.py file and simply passed the chatbot response to the new function to display and I got a 500 error. The code from my views.py, urls.py, main.html, and main_2.html pages is posted below. What am I missing? Thanks in advance.

Link from Django Model's "absolute url" to its admin page
According to the docs, you can specify a get_absolute_url in your Django Model for a "View on site" button to show up on Django Admin. However, how would you do the opposite? A link on the above defined "absolute url" that takes you to the admin page for that instance? I can think of ways to hardcode the admin url and fill in just the instance ID, but I was hoping for a pythonic way (e.g. instance.get_admin_url()) Thanks for the help!
