# Task expires after one minute from now.
add.apply_async(args=[10, 10], expires=60)
Я использую:
from tasks import add
result = add.apply_async(args=[10, 10], expires=6000)
printus(result)
def printus(result):
print (result) #task id
print (result.ready()) # returns True if the task has finished processing.
print (result.result) # task is not ready, so no return value yet.
print (result.get()) # Waits until the task is done and returns the retval.
print (result.result) # direct access to result, doesn't re-raise errors.
print (result.successful()) # returns True if the task didn't end in failure.)
