如何将导入预加载到Django的manage.py shell命令中？ [英] How do I preload imports into Django's manage.py shell command?

问题描述

当我在Django项目上运行manage.py shell进行查看时，通常会在shell的开头运行一些常见的导入操作（例如，我始终希望导入模型文件。）我每次运行shell命令时都会自动运行这些代码吗？

When I run manage.py shell on my Django project to take a peek at something there are common imports that I always want to run at the start of the shell (e.g. I always want to import my model files.) How can I have these run automatically everytime I run the shell command?

第二个相关问题，当我按下向上箭头时，我得到的是 ^ A字符，而不是以前运行的字符在manage.py外壳程序（以及我的常规python外壳程序）中的命令，如何解决此问题，使其像在Linux / Unix命令行上一样加载上一个命令？

2nd related question, when I hit the up arrow I get the "^A" character instead of the previously run command in the manage.py shell (and in my regular python shell), how can I fix this so it loads the previous command like on the Linux/Unix command line?

推荐答案

对于第一个问题，请看 django-extensions 项目。它将在启动外壳时加载所有模型文件。该项目还有很多其他有用的技巧，因此绝对值得一试。

For the first question, look at the manage.py shell_plus command provided by the django-extensions project. It will load all your model files on shell startup. The project has got a whole load of other useful tricks too, so it's definitely worth checking out.

对于第二个问题，我只能猜测您需要安装 readline 。

For the second question, I can only guess that you need to install readline.
