Celery/django - chunk tasks
I have a lot of tasks that are being generated that I would like to group in to chunks, but I think in the opposite way as Celery does. From my understanding, I can use the chunks feature to split up a list of items when I create the task. I would like to do the opposite. The data I have is being produced one at a time from different endpoints. But I would like to process them in chunks so that I can insert them in to a database in single transactions. So essentially I'd like to add items to a queue 1 at a time, and dequeue them 100 at a time (either at some specified time interval or once the queue reaches a certain level) and use a transaction to insert all of them in to a database. This would save me from Is this possible with celery? Would it be easier to drop down to redis and create a custom queue there? -

How to pass Serizalizer Fields to front-end Framework from RESTful API - DRF (Django)?
I want to use Svelte in the front-end and DRF (Django) in the back-end. This is what I have right now: #models.py class Student(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) # serializers.py class StudentSerializer(serializers.ModelSerializer): class Meta: model = Student fields = "__all__" But when I know want to create a form in the front-end (Svelte) I have to manually do that? Is there a way of requesting a json with all the required fields and the to build a form around it. Like first I request api.com/students/form wich returns a json: { "fields":[ "first_name", "last_name" ] } And then I could just iterate over the fields in "fields" and create <input> tags for the form acordingly. -

In this website a user registers, chooses some plan and then book an intructor to teach him/ her driving. A user after loging in has to accept an agreement and also has an udate plan page.

Telegram Oauth2 with Django
I am exploring ways to send telegram messages to the users using Telegram bot from my Django application. The bot should be able to initiate the conversation - these messages are more like alerts and updates but not conversations. From Telegram developer documentation I could not find a standard OAuth2 implementation with Telegram to get access tokens for sending messages to the users using REST APIs. Does anyone know Oauth flow implementation for Telegram if at all it exists Sending messages using API - I am not planning to run a bot server. The messages just need to be pushed to the user - more like push notifications. Appreciate your help.
