Built-in task states.
States¶
See Государства.
Sets¶
READY_STATES¶
Set of states meaning the task result is ready (has been executed).
UNREADY_STATES¶
Set of states meaning the task result is not ready (hasn’t been executed).
EXCEPTION_STATES¶
Set of states meaning the task returned an exception.
PROPAGATE_STATES¶
Set of exception states that should propagate exceptions to the user.
ALL_STATES¶
Set of all possible states.
Misc¶
- celery.states.FAILURE = 'FAILURE'¶
Task failed
- celery.states.PENDING = 'PENDING'¶
Task state is unknown (assumed pending since you know the id).
- celery.states.RECEIVED = 'RECEIVED'¶
Task was received by a worker (only used in events).
- celery.states.RETRY = 'RETRY'¶
Task is waiting for retry.
- celery.states.REVOKED = 'REVOKED'¶
Task was revoked.
- celery.states.STARTED = 'STARTED'¶
Task was started by a worker (
task_track_started).
- celery.states.SUCCESS = 'SUCCESS'¶
Task succeeded
- celery.states.precedence(state: str) int[исходный код]¶
Get the precedence index for state.
Lower index means higher precedence.
- class celery.states.state[исходный код]¶
Task state.
State is a subclass of
str, implementing comparison methods adhering to state precedence rules:>>> from celery.states import state, PENDING, SUCCESS >>> state(PENDING) < state(SUCCESS) True
Any custom state is considered to be lower than
FAILUREandSUCCESS, but higher than any of the other built-in states:>>> state('PROGRESS') > state(STARTED) True >>> state('PROGRESS') > state('SUCCESS') False
