Django:在runserver之后立即运行脚本 [英] Django: Run a script right after runserver

问题描述

上下文:

我在数据库上有一个表，该表使用来自外部数据库的值.该外部数据库会定期更新其值.

I have a table on the database that uses values from an external database. This external database updates its values periodically.

问题:

为了在每次启动服务器时更新数据库，我想在runserver之后立即运行脚本.

In order to update my database everytime i start the server, I want to run a script right after the runserver.

潜在的解决方案:

我已经看到可以从某个应用程序运行脚本，这是我感兴趣的事情.这可以通过使用 django-extensions 来实现:

I have seen that it is possible to run a script from a certain app, which is something I'm interested in. This is achievable by using the django-extensions:

https://django-extensions.readthedocs.io/en/latest/runscript.html

但是，此脚本仅使用以下命令运行:

However, this script only runs with the following command:

python manage.py runscript your_script

还有其他方法可以从应用程序运行脚本并在runserver命令之后立即执行该脚本吗?我愿意接受建议！

Is there any other way to run a script from an app and execute it right after the runserver command? I am open to suggestions!

预先感谢

更新

感谢@Raydel Miranda的发言，我觉得我留下了一些信息.

Thanks to @Raydel Miranda for the remarks, I feel i left some information behind.

我的目标是，一旦启动服务器，我打算打开一个套接字来维护数据库的更新.

My goal is, once I start the server I'm planning to open a socket to maintain my database updated.

推荐答案

您可以在顶级 urls.py 中执行代码.该模块将被导入并执行一次.

You can execute the code in the top-level urls.py. That module is imported and executed once.

urls.py

from django.confs.urls.defaults import *
from your_script import one_time_startup_function

urlpatterns = ...

one_time_startup_function()
