问题描述
我正试图让我的django应用程序将任务提交给芹菜工人，并且当该工人附加运行时成功了。添加--detach后，任务将无法注册。
[2020-10-26 04:09:33,159: ERROR/MainProcess] Received unregistered task of type 'devapp.tasks.create_random_files'.
The message has been ignored and discarded.
Did you remember to import the module containing this task?
Or maybe you're using relative imports?
Please see
http://docs.celeryq.org/en/latest/internals/protocol.html
for more information.
The full contents of the message body was:
'[[20,"blah",5120],{},{"callbacks": null,"errbacks": null,"chain": null,"chord": null}]' (93b)
Traceback (most recent call last):
File "/pysite/project/venv/lib/python3.6/site-packages/celery/worker/consumer/consumer.py",line 562,in on_task_received
strategy = strategies[type_]
KeyError: 'devapp.tasks.create_random_files'
在我的task.py中，我有
import os
import string
import subprocess
from celery import shared_task,task
@shared_task(name='devapp.tasks.create_random_files')
def create_random_files(total,filename,size):
for i in range(int(total)):
filenum = str(i).zfill(5)
rnd_filename = '/brdis/{}-{}'.format(filenum,filename)
with open(rnd_filename,'wb') as f:
f.write(os.urandom(size))
f.close
return '{} random files created'.format(total)
在我的views.py中，我有
from django.shortcuts import render
from django.http import HttpResponse
from django.contrib import messages
from django.views.generic import TemplateView
from django.views.generic.list import ListView
from django.views.generic.edit import FormView
from django.shortcuts import redirect
from .forms import CreaterandomFilesForm,GetFileListForm,ClamScanFileForm
from .tasks import create_random_files,clamscanfile
class ClamScanFileView(FormView):
template_name = 'devapp/clamscan_file.html'
form_class = ClamScanFileForm
def form_valid(self,form):
filename = form.cleaned_data.get('filename')
clamscanfile.delay(filename)
messages.success(self.request,'We are scanning your file!s Wait a moment and refresh this page.')
return redirect('files_list')
我知道这可能是相对进口的（我需要弄清楚一些其他事情），但是我不明白为什么在芹菜工人命令中添加--detach会产生此错误：
celery -A project worker -E --loglevel=INFO --logfile=/var/log/celery/celeryd.log --pidfile=/var/run/celery/celeryd.pid
工作正常，但是...
celery -A project worker -E --loglevel=INFO --logfile=/var/log/celery/celeryd.log --pidfile=/var/run/celery/celeryd.pid --detach
启动工作程序但不注册任务？
任何帮助表示赞赏。
FWIW
celery report

解决方法
这是4.4.7的错误。降级到4.4.6或升级到5应该可以解决。
