在IPython中运行Django shell

Question

我试图在IPython中运行Django shell:

ipython manage.py shell

它报告以下错误:

键入"manage.py help"以获取有关特定子命令的帮助.

我搜索并找到了一个流行的解决方案,可以指导您安装django.extensions并启用它settings.

我正在创建一个最小的项目,而解决方案很重.同时,我必须在每个项目上安装并启用它.

有轻量级的方式吗？

我开始一个新项目, python manage.py shell -i ipython无法工作

$ python manage.py shell -i ipython
CommandError: Couldn't import ipython interface.
$ ipython --version
6.4.0

Answer 1

只需安装ipython到您的virtualenv.manage.py shell应该默认使用它.

您还可以使用manage.py shell与-i选项明确选择一个shell(这些选项ipython,bpython或python用于常规的Python壳):

python manage.py shell -i ipython

无论哪种方式,您都需要安装ipython到您的环境中,但您无需对项目设置进行任何更改.

如果ipython已经安装在您的系统中virtualenv，那么下面的任何命令都将工作相同（在带有示例片段的命令之后已经在下面介绍了）。

• python manage.py shell
\n
• python manage.py -i ipython
