Have you tried using Celery?
No
I think I can be handed with out queue

Give it a try...with a celery+redis setup. We run a script like that too ...and it works fine...at times, the data is large enough and it takes 30 minutes to 45 minutes to process
Ashish
But it doesn't time out

And even works on a basic 4GB ram shared droplet on Digital Ocean

Hello
My friends, I send some data from the front (react) to the back end (django) and there I put the data in the data frame and some calculations are done and the answer is sent to the front.
When the volume of input information is small, the system works without problems, but when I increase the volume of information and more, sometimes it works, but most of the time it is an error.
500 internal server error
Gives. Is it the only way to use a more powerful server? I now have a tri-core server. Because if the number of users increases, this problem may also occur
thank you
But don’t you think it won’t be scalable this way? What if you make it into a distributable system, then each node should be that strong to handle this processing?
Rohan
Doing that task async in a queue will be much better.

I keep getting, cannot assign AnonymousUser object: Post.author must be a User instance.
It clearly states that the user object you are trying to create/map or update is an unknown user.

In user, cause user has books (I guess). Indeed, you put it in the model. In database, this will be two 1:n tables.

Got stuck on it. Urgent help needed
Is it urgent?
You shouldn't be here, wasting time and poking strangers and waiting for them to do your job for you.
Search on Google/DuckDuckGo, do the research, and solve your problem yourself, nobody here will drop what they're doing to do your job, just because "it's urgent!".
Have a nice day! 😉

> serializers.py
> tests.py

Yes, once you receive the data in the front-end, you can do whatever you want with it

It's like you have a lot of books and you want to organize them in different shelves ..your shelves your rules

What's the way any idea
Dev
?
Ashish
Depends on the frontend you are using
Dev
It's react js
Ashish
There are libraries like Axios to fetch API DATA IN REACT
Ashish
Now it's offtopic and more of a react question than Django

I agree

When looping objects in a model. How can I specify that the loop should display only the first object of the model and not all
Charly
When looping objects in a model. How can I specify that the loop should display only the first object of the model and not all
then why loop instead of just getting the firs object?
Seun
then why loop instead of just getting the firs object?
The thing is I have a grid structure in my template.
The grid structure contains 6 boxes. 5 are same in sizes and only one is different in size.
So I want to loop but I want 5 out of my objects to go to the five similar boxes and only the objects precisely the first one to be in the one different box
