Question

我想在celerybeat-mongo的帮助下使用python 2.7在celery中动态执行一些任务，因为我希望celery从mongo数据库动态地获取任务细节。这是我的示例代码：

from celery import Celery

app = Celery('tasks', broker='redis://localhost')

app.config_from_object('celeryconfig')

@app.task
def add(x, y):
    return int(x) + int(y)

并根据celerybeat-mongo celerybeat-mongo

的文件

我的mongodb文件是

{
    "_id" : ObjectId("59786aa52f3dd74f7a2943d4"),
    "_cls" : "PeriodicTask",
    "name" : "Addition",
    "task" : "task.add",
    "enabled" : true,
    "interval" : {
        "every" : 1,
        "period" : "minute"
    },
    "args" : [
        "2",
        "5"
    ],
    "kwargs" : {
        "max_targets" : "100"
    }
}

当我尝试执行以下命令时：

celery beat -S celerybeatmongo.schedulers.MongoScheduler

它显示错误为 -

我不明白它指向哪个关键字？

类型错误：关键字必须是字符串
