为什么Django不会使用IPython？-Whywon'tDjangouseIPython?

Try installing it into virtualenv! :-)

I love iPython but don't like installing it in all my virtualenvs, and I've found a good solution to allow for that. Instead of using python manage.py shell, you can just use the system iPython directly.

我喜欢iPython，但不喜欢在我所有的virtualenvs中安装它，我找到了一个很好的解决方案来实现这一目标。您可以直接使用系统iPython，而不是使用python manage.py shell。

In order for this to work properly, you need to set the DJANGO_SETTINGS_MODULE so that it corresponds to your project.

为了使其正常工作，您需要设置DJANGO_SETTINGS_MODULE，使其与您的项目相对应。

export DJANGO_SETTINGS_MODULE=yourproject.settings

导出DJANGO_SETTINGS_MODULE = yourproject.settings

If this is your only Django project, the easiest solution is to add that line to your .bashrc.

如果这是您唯一的Django项目，最简单的解决方案是将该行添加到.bashrc中。

If you have several Django projects and want to avoid having to change the variable every time you switch between projects, you can add that export line above tailored to each project to the postactivate scripts of all your Django virtualenvs. For me, the postactivate script is at ~/.virtualenvs/myvenv/bin/postactivate.

如果你有几个Django项目，并希望避免每次在项目之间切换时都要更改变量，你可以将上面为每个项目定制的导出行添加到所有Django virtualenvs的postactivate脚本中。对我来说，postactivate脚本位于〜/ .virtualenvs / myvenv / bin / postactivate。

In my case, I really want to run IPython in multiple virtual environments (created using the default --no-site-packages) each used for a different Django project. I did not want to install IPython in each env.

在我的例子中，我真的想在多个虚拟环境中运行IPython（使用默认的--no-site-packages创建），每个环境都用于不同的Django项目。我不想在每个环境中安装IPython。

As @Arash mentioned, exporting the DJANGO_SETTINGS_MODULE works but it's difficult to manage it when you have multiple projects.

正如@Arash所提到的，导出DJANGO_SETTINGS_MODULE可以工作，但是当你有多个项目时很难管理它。

I finally solved this issue in two parts.

我终于分两部分解决了这个问题。

First I added the directories "/usr/lib/python2.7/dist-packages" and "/usr/lib/pymodules/python2.7"to sys.path in the /usr/bin/ipython script as mentioned here.

首先，我在/ usr / bin / ipython脚本中添加了目录“/usr/lib/python2.7/dist-packages”和“/usr/lib/pymodules/python2.7”到sys.path，如下所述。

Next, I use a manage_to_ipython.py script to create a django-project-specific script called runipython.py leveraging the manage.py file created by django-admin.py

接下来，我使用manage_to_ipython.py脚本创建一个名为runipython.py的django-project特定脚本，利用django-admin.py创建的manage.py文件

Once in each Django project, $cd then run python manage_to_ipython.py

在每个Django项目中，$ cd 然后运行python manage_to_ipython.py

Now, to run IPython simply type ./runipython.py

现在，要运行IPython，只需输入./runipython.py即可

The modified /usr/bin/ipython and the manage_to_ipython.py scripts can be found here.

可以在此处找到修改后的/ usr / bin / ipython和manage_to_ipython.py脚本。
