AdminSet安装部署报错解决方法(亲测有效)

阅读更多关于 AdminSet安装部署报错解决方法(亲测有效)

github上有提供安装方法，但是实际安装部署过程中，各种报错。。。 https://github.com/guohongze/adminset 后经过不断调试，总算安装成功。特此记录一下报错解决步骤错误1： ERROR: pyasn1-modules 0.2.8 has requirement pyasn1<0.5.0,>=0.4.6, but you'll have pyasn1 0.4.1 which is incompatible. 解决方法：安装新版pyasn1。方法如下：下载符合版本要求的pyasn1源码压缩包，解压，进入文件夹 python setup.py build python setup.py install 修改 requirements.txt 中pyasn1的版本 admin/abc123xyz 错误2： ERROR: Cannot uninstall 'requests'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall. 解决方法——》request模块会报错，修改 requirements.txt

Call Django celery task by name

阅读更多关于 Call Django celery task by name

问题 I need to call a celery task (in tasks.py) from models.py, the only problem is, tasks.py imports models.py, so I can't import tasks.py from models.py. Is there some way to call a celery task simply using its name, without having to import it? A similar thing is implemented for ForeignKey fields for the same reason (preventing circular imports). 回答1: Yes, there is. You can use: from celery.execute import send_task send_task('my_task', [], kwargs) Be sure that you task function has a name: from

Celery logger configuration

问题 I'm using Django 1.10, python 3.5 and celery 4.1.0 I'm trying to log celery tasks info into a file. So I tried as suggested in celery documentation - from celery.utils.log import get_task_logger logger = get_task_logger(__name__) and tried to log a message inside the task - logger.info(message) I expected it to log to my default logger. But it didn't. So I added to settings a dedicated logger named 'celery.task' (as I understand from documentation): LOGGING = { 'version': 1, 'disable_existing

flask application with watchdog observer

阅读更多关于 flask application with watchdog observer

问题 I am seeking for an example for flask-based web application with watchdog observer. More specifically, I want to use the watchdog observer to detect any changes in pre-defined directories and update a web application based on the changes. I can find many examples for each of them, i.e. flask-based web applications and watchdog observer examples. But, I don't know how to integrate two examples and run them smoothly. Can anyone provide a simple example? Also, I wonder if I can run the watchdog

问题 I'm following this tutorial, and adjusting the Celery-background related code to my project. In my case I am operating in a Docker environment, and I have a secured site (i.e. https://localhost). which requires secured ssl communication. I adjusted the code for secure connection. I had initial connection problems, which created log error messages, but I was able to solve - see here. Now the log file is quite, but I think that I still have connection problems. As a result, at runtime, when
