celery/celery#4201 (master - b9a84ca : shalev67): The build was broken.

I'm having a little trouble wrapping my head around a specific flow

I am trying to build a workflow that is fairly synchronous: A -> B -> C -> group(d) -> E (aggregate) then back to A

Am I thinking right that the best way to achieve that is to use the same queue?

The big problem is with group(d)

In the same queue the order is fine for A -> B -> C but I would like to find a way to fan out from C do a group of tasks which then aggregate on E, it works fine with a chord it's just that it's celery is working through A to C for all messages until that is exhausted

then moving to d and e

Is there a way to update a running chain for example?

The group I want to fan out to are faily long running tasks, around 20 - 30 seconds. As individual tasks it's not bad and it allows for easier retrying, however there can be hundreds generated and suddenly having one worker to the job isn't so practical

Hi, [django] is app.on_after_configure signal trigered after detected tasks files are imported? (I would like to register scheduler in tasks files, would it be an ugly pattern?)

Hi All, I am reading this guide on setting up async tasks https://realpython.com/blog/python/asynchronous... - and the periodic task I have written is just not being picked up, i looked at the celery docs for the version i have installed and it looks like the decorators have been removed

have they truly been removed and I need to do it the way documented?

SteamWells: are you using celery 4.0+?

if yes, this tutorial is out of date

yes I am

you have to make a celery app instance in your project (like a wsgi instance), and use from project import app \n @app.task

but then i pip installed v 3.1.x from the tutorial and ran it again

no such luck

i have a celery app instance

Hell, conda has no Celery in their repo...

(ho, sorry, I thought it was even more out of date as I didn't read ^^)

no worries

im still investigating it, I think i can see what the issue is

but just checking

did you read this document? http://docs.celeryproject.org/en/latest/django/...

aye yes, there are some differences

i might just scrap my version and use the latest one and follow the docs

yea, even settings names

i just wanted to get this working as I have to demo this soon

but still, better do it properly

what do you mean by "soon"

a week

eos

but in devops time, that will soon come :D

well on version 4.0.2 it still seems to work with the decorator

just had to remove the settings.INSTALLED_APPS arg in auto discover tasks

simple as

I am a newbie here and I just started using celery, I have been struggling with this error and I feel it is easy to fix, so basically whenever I want to start a worker I an error saying AppRegistryNotReady: Apps aren't loaded yet.

Am I missing somethin in configuration ?

maxmayer, http://stackoverflow.com/questions/25493872/dja...

maxmayer, is the answer there helping?

Dejan: trying it right now

Dejan: into another issue. it is not recognizing the apps module anymore, "ImportError: No module named apps"

it a django project by the way

I guessed so

I can't help with django

Never used it in my life

Dejan: Thanks though for your help :)

that one is easy - Python can't find the module to import

you are probably in the wrong path
