Question

这是发送邮件的Celery任务，有趣的是，一切都可以在DEBUG = True模式下正常运行，但在生产环境DEBUG = False中则无法正常工作。在发送操作期间并在激活的调试模式下运行celery worker -A invoice2 --loglevel = debug会显示以下内容：

 ERROR/ForkPoolWorker-5] Task enviar_documentos[xxx] raised unexpected: TypeError("enviar_documentos_async() got an unexpected keyword argument 'cliente'",)

首先使用延迟启动发送文件：

from django.conf import settings
from notifications.tasks import send_async_documents

def send_documents (company, client, documents, type, template = "invoice", context = None):
    send_documents = send_documents_async.delay
    send_documents (type = type,
                    company = company.pk,
                    client = client.pk,
                    template = template,
                    context = context)

第二，任务：

from celery_app import app
@app.task (name = "send_documents")

def enviar_documentos_async (company, client, documents, type = "FacturaVenta", template = "invoice", context = None):
     if not context:
       context = {}
       klass = KLASS.get (type)
       queryset = klass.objects.filter (pk__in = documents)
       em = Empresa.objects.get (pk = company)
       cl = Cliente.objects.get (pk = client)
       .
       .
       return send_email(
           mail_from = "\"{0.name}\"><{0.email}>".format(em),
           mail_to = cl.email,
           type = template,
           context = context,
           attachments = attachments)

第三，发送电子邮件：

from django.core.mail import EmailMessage
from django.template import Context, Template

def send_email(mail_from, mail_to, type, context = None, attachments = None):
   subject = Template(subject.type).render(mail_context) .replace ("\ n", "")
   message = Template(type.body).render(mail_context)
   ...
   msg = EmailMessage (
          subject,
          linebreaks (message),
          mail_from,
          mail_to)

Answer 1

您在哪里调用enviar_documentos_async函数？可能是您提供 client 参数（使用cliente而不是client）的错字。

Answer 2

在Django生产debug = False的情况下，Celery无法通过运行celery worker -A myapp --loglevel=info直接工作，因此还必须启动Celery脚本daemonization

bin/celery worker --help

嵌入式节拍选项： -B，--beat同时运行celery beat定期任务计划程序。请注意，只能有一个实例这项服务。 ..注意：： -B用于发展宗旨。对于生产环境，您需要单独开始芹菜拍打。

重要参数：-B celery worker -A myapp --loglevel=info -B

无法在Debug = False中使用Django启动工作进程Celery任务（生产）
