Question

我正在使用Celery进行分发任务的项目。为了将任务路由到特定的工作者（因为它需要由前一个任务创建的特定文件），我正在尝试使用celery.utils.worker_direct。

我所做的基本上是这样的：

@app.task(bind=True)
def task_A(self, arg):
    worker = str(self.request.hostname)
    # ...
    s = task_B.s(arg1, worker)
    s.delay()

@app.task
def task_B(arg1, worker):
    task_C.apply_async((arg1, arg2), queue=worker_direct(worker))

@app.task
def task_C(arg1, arg2):
    pass

执行task_C.apply_async((arg1, arg2), queue=worker_direct(worker))时，我收到此错误：

TypeError: object of type 'Queue' has no len()

我做错了什么？

找到解决方案：

        stringValue = cobContractNetworkGroup.SelectedValue

    If stringValue = "Something" Then

        cobAffiliation.Enabled = True

        AppReturnAffiliationBindingSource.Filter = "AffiliationType LIKE '%" & AppReturnGroupContractNetworkBindingSource.Current & "%' "

    Else
        cobAffiliation.Enabled = False
        AppReturnAffiliationBindingSource.Filter = ""

    End If
