celery groupresult,celery.result ¶. Task results/state and results for groups of tasks. class celery.result.AsyncResult(id, backend=None, task_name=None, app=None, .

Is there a way to obtain a GroupResult object (i.e. my result) starting from the taskset id? Something like what is done in this question, but working with celery groups. .

class celery.result.GroupResult(id=None, results=None, **kwargs) [source] ¶ Like ResultSet, but with an associated id. This type is returned by group, and the .celery groupresult class celery.result.GroupResult(id=None, results=None, **kwargs) [source] ¶ Like ResultSet, but with an associated id. This type is returned by group, and the .This document describes the current stable version of Celery (5.4). For development docs, go here . Source code for celery.result.This extension enables you to store Celery task and group results using the Django ORM. It defines 2 models ( django_celery_results.models.TaskResult and .If you call the group, the tasks will be applied one after another in the current process, and a GroupResult instance is returned that can be used to keep track of the results, or tell how many tasks are ready and so on: class GroupResult (ResultSet): """Like :class:`ResultSet`, but with an associated id. This type is returned by :class:`~celery.group`, and the deprecated .

Looking in the GroupResult children also looks fine, I can see that it has two children - group(add.si(1, 1) and add.si(2, 2) and its parent is AsyncResult instance .class celery.result.GroupResult (id=None, results=None, parent=None, **kwargs) [源代码] ¶ Like ResultSet, but with an associated id. This type is returned by group. It .

I'm still hitting this issue with master branch of django-celery-results when using CELERY_RESULT_BACKEND = "django-db". It looks like .

class celery.result.GroupResult (id = None, results = None, parent = None, ** kwargs) [source] ¶ Like ResultSet, but with an associated id. This type is returned by group. It enables inspection of the tasks state and return values as a single entity. Parameters. id – The id of the group. results (Sequence[AsyncResult]) – List of result .This type is returned by :class:`~celery.group`. It enables inspection of the tasks state and return values as a single entity. Arguments: id (str): The id of the group. results (Sequence[AsyncResult]): List of result instances. parent (ResultBase): Parent result of .

本文整理汇总了Python中celery.result.GroupResult类的典型用法代码示例。如果您正苦于以下问题：Python GroupResult类的具体用法？Python GroupResult怎么用？Python GroupResult使用的例子？那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。

Group result ordering¶ Versions of Celery up to and including 4.4.6 used an unsorted list to store result objects for groups in the Redis backend. This can cause those results to be be returned in a different order to their associated tasks in the original group instantiation. Celery 4.4.7 introduced an opt-in behaviour which fixes this issue .

Added in version 4.0. root_id: The unique id of the first task in the workflow this task is part of (if any). parent_id: The unique id of the task that called this task (if any). chain: Reversed list of tasks that form a chain (if any). The last item in this list will be the next task to succeed the current task.

In order for Celery to record that a task is running, you must set task_track_started to True. Here is a simple task that tests this: print self.AsyncResult(self.request.id).state. When the option task_track_started is False, which is the default, the state show is PENDING even though the task has started.This document describes Celery’s uniform “Calling API” used by task instances and the canvas. The API defines a standard set of execution options, as well as three methods: apply_async (args [,kwargs [,.]]) Sends a task message. Shortcut to send a task message, but doesn’t support execution options.

from celery import subtask subtask (task_name_or_cls, args, kwargs, options) For convenience every task also has a shortcut to create subtasks: task. subtask (args, kwargs, options) subtask is actually a dict subclass, which means it can be serialized with JSON or other encodings that doesn’t support complex Python objects. 使用celery canvas中的group任务类型实现分组任务. 1. 需求背景：. 某个业务需求实现过程需要对发布到celery的异步任务进行拆分，得到两个并行执行的子任务，同时在主任务的进度反馈中需要更新子任务的进度；. 2. 实现方案：. 1. 任务发布端通过 "send_task ()" 方式 .

34. I want to create a group from a list returned by a Celery task, so that for each item in the task result set, one task will be added to the group. Here's a simple code example to explain the use case. The ??? should be the result from the previous task. @celery.task. def get_list(amount): Celery’s group enables you to execute multiple tasks concurrently and gather their results in a single response. This is a fantastic way to boost efficiency and speed up your task processing. to use "Getting started with celery" in the docs as a staring point: tasks.py: return x + y. your code: add.s(1, 1), add.s(2, 2) elsewhere: you example shows you running restore in the same context as the apply_async - I'm assuming that's a simplificaiton and that you know you don't need to use restore unless you are in a different process or .If you want to run django-celery-results with MySQL, you might run into some issues. One such issue is when you try to run python manage.py migrate django_celery_results, you might get the following error: django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 767 bytes') To get around this issue, you can set:celery.result — Celery 3.1.11 documentationNew lowercase settings ¶. Version 4.0 introduced new lower case settings and setting organization. The major difference between previous versions, apart from the lower case names, are the renaming of some prefixes, like celery_beat_ to beat_, celeryd_ to worker_, and most of the top level celery_ settings have been moved into a new task_ prefix.

Parameters:. timeout – How long to wait, in seconds, before the operation times out.This is the setting for the publisher (celery client) and is different from timeout parameter of @app.task, which is the setting for the worker.The task .

In order to get the result of a group a different object is needed - the celery.result.GroupResult.Both AsyncResult that you tried to use, and GroupResult are ResultBase subtypes (although GroupResult is a subclass of ResultSet, which is a subclass of ResultBase, just like AsyncResult) so they behave quite similar.class celery.result.GroupResult(id=None, results=None, **kwargs) [源代码] ¶. Like ResultSet, but with an associated id. This type is returned by group, and the deprecated TaskSet, meth:~celery.task.TaskSet.apply_async method. It enables inspection of the tasks state and return values as a single entity.
