将 CELERY_ALWAYS_EAGER 设置为 True 会引发错误答案

【问题标题】：Setting CELERY_ALWAYS_EAGER to True throws Errors将 CELERY_ALWAYS_EAGER 设置为 True 会引发错误

【问题描述】：

我的代码中有一些异步调用。像这样：

send_message_to_install.delay(install, alert.message, badge, code,
                            campaign=alert.campaign, **kwargs)

我对返回任何结果不感兴趣，重要的是该函数在运行测试时同步执行 - 不会引发错误。

在测试时，我尝试将我的设置文件中的 CELERY_ALWAYS_EAGER 设置为 True：

if "test" in sys.argv:
    CELERY_ALWAYS_EAGER = True

我也尝试在测试中设置它：

from django.conf import settings
settings.CELERY_ALWAYS_EAGER = True

这两种尝试都使我的测试抛出错误（没有“.delay”它可以正常工作）：

ImportError: No module named tasks

【问题讨论】：

你的send_message_to_install在哪里？

标签： python django celery django-celery

【解决方案1】：

我太傻了。我的 CELERY_ROUTES 中有一个“messages.tasks”。但是没有文件 /messages/tasks.py 。

感谢您的回帖！

【解决方案2】：

您可以使用CeleryTestRunner 进行测试。它会自动在 ALWAYS_EAGER 模式下运行你的测试
