The problem: @shared_task decorator doesn't work, when I import data from custom files. I mean, when I start celery, all tasks under @shared_task doesn't appear in list of tasks.
For example, in this case @shared_task decorator doesn't work:
from __future__ import absolute_import, unicode_literals
from celery import shared_task
from .models import foo
@shared_task
def my_foo_backup(id):
my_foo = foo(....)
...
...
This is example, when @shared_task works:
from __future__ import absolute_import, unicode_literals
from celery import shared_task
@shared_task
def my_foo_backup(id):
my_foo = foo(....)
...
...
Why?!?
The solution to that problem was to move import commands inside the function. In that way it works fine and according to the rules of PEP8.
from __future__ import absolute_import, unicode_literals
from celery import shared_task
@shared_task
def my_foo_backup(id):
from .models import foo
my_foo = foo(....)
...
...
