Trying to create dockerized microservices which will decomposed and interact between each other. Can we facilitate this communication through celery, instead of http?

Given all services are on same network as celery

Hello everyone! Need advice: how best to check if an object exists in the database using QuerySets? Im using try, except with QuerySets.objects.get(id=N) but not shure if this best choise.
Thank you
Use get_object_or_404(ModelClassName, fields...)
If the data does not exist It will throw a 404 error
Rohan
They can reach celery using it’s service name defined in compose

If they run on different Ec2 instances ?

Then make sure your celery is reachable to outside world or your services but obviously scaling won’t work on that and this is not gonna be good on a production environment
Rohan
In fact compose is not for production environment

Okay, in that case to achieve scalability and smooth communication between the microservices what can be used? Our aim is to first run the docker images in 2-3 servers in a distributed manner, as it scales we keep adding more servers. All in production
Rohan
REST APIs?
Rohan
Or your focus is on speed?
Rohan
It’s like a trade off between speed and development speed
Rohan
You can use gRPC with django but then you’ll also have to maintain a client that exposes those rpc methods
Rohan
And I’ve never seen someone use celery to make services contact between themselves
Rohan
It’s so fragile and complicated that I’d rather use a redis cache to serve requests than do that.

Understood, thanks for the suggestions... Can you suggest any resources which describes architecture of such highly scalable system in Django, including dockerized microservices and efficient communication

There are tons of article on the internet and each gives you a lot of insight
Rohan
For dockerization, that’s a simple process to isolate a service
Rohan
Migrate to ECS instead of running bare EC2s if you already use dockers
Rohan
And if you have money to put in your production environment, try Fargate serverless.

Noted, will do some digging and find out the tradeoff. Thanks a lot for the recommendations
.

Because its just broker
Vishal
Show your code
All the details are mentioned in the issue. Please tell me you need something in specific.
.
Celery is message broker
Rohan
I dont use this shit
Then don’t provide insights on it to someone who’s already struggling with it.

Sure, i would recommend another task queue

His original problem has nothing to do with task queues
Rohan
It’s more about interaction of microservices.

Rohan
And how does queues plug in into that equation?

Hi, On a new Django website, I can enter the site with http: // DomainName, I cannot enter when entering www.domainname, how can I solve this problem?

This has more to do with your web server configuration, configuring your name servers than it has to do with django.

how to run this django project in my pc
AV
Hi, i need a help) I have the code:
get_tasks_coro = sync_to_async(TaskManagerTasks.objects.all, thread_sensitive=False)
tasks = await get_tasks_coro()
but I will get the “SynchronousOnlyOperation” exception, i don’t understand what is wrong … My python version 3.6.9, thanks in advance!
AV
Might be python version
I think so. And there is one interesting moment, the loop.run_in_executor method creates a separated daemon thread for any synchronous code executing, but there will be the same exception as SynchronousOnlyOperations. I have to use threading.Thread in the loop.run_in_executor explicitly.

Could any body suggest me what topics required in python for django

What are you trying to do
I have a necessity to work with a database asynchronously. My dbms is postgresql with the psycopg adapter. I wrote an asynchronous server with the asyncio and multiprocessing, it works in the dedicated process on the dedicated core of the CPU.

hey guys, according to black formatter codestyle we should use double quotes (“”), while django auto-generated code uses ordinary quotes(‘’). what is a true way to use to resolve this problem in codestyle ambiguity?

Your question is not related to Django.
If it's a Python related question go to @Python group, otherwise please move to @PythonOfftopic group and ask there.

if you're using black, then follow what black tells you, or configure it to follow what you want to have ¯\_(ツ)_/¯

You can set black to use single quote if you like it more
.
.
u can set black -S
.
or use another formatter, like autopep8, yapf
.
or both
