我将尝试在我的Django应用程序中使用celery作为后台进程。 Django版本为1.4.8,最新适用的celery版本为3.1.25。
我使用Redis(3.1.0)作为代理和后端,json作为序列化程序。
当我启动工作程序
完整的回溯信息:
我使用Redis(3.1.0)作为代理和后端,json作为序列化程序。
当我启动工作程序
celery -A celery_app worker -l info
时,我会收到属性错误'unicode' object has no attribute 'iteritems'
我的settings.py文件:BROKER_URL = 'redis://localhost'
CELERY_RESULT_BACKEND = 'redis://localhost/'
CELERY_ACCEPT_CONTENT = ['json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'
CELERY_STORE_ERRORS_EVEN_IF_IGNORED = True
celery_app.py:
import sys
from django.conf import settings
from celery import Celery
project_root = os.path.dirname(__file__)
sys.path.insert(0, os.path.join(project_root, '../env'))
sys.path.insert(0, os.path.join(project_root, '../'))
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
app = Celery('project')
app.config_from_object('project.settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS, force=True)
tasks.py:
@celery_app.task
def sample_task(x):
return 'Test response'
这就是我运行此任务的方法:
sample_task.delay({'key': 'test'})
我收到了以下错误信息:
File "/Users/user/project/venv/lib/python2.7/site-packages/redis/_compat.py", line 94, in iteritems
return x.iteritems()

我尝试在互联网上找到问题,并尝试传递其他参数到任务中。我不知道如何调试Celery进程,也找不到自己的解决方案。请帮帮我。
