Question

I tried two ways to do code completion, one is OK, the other fails.

OK one does like below:

$> cd myDjangoProject/
myDjangoProject $> export PYTHONPATH="."
myDjangoProject $> DJANGO_SETTINGS_MODULE=settings vim urls.py

Then ^x ^o can work well. But this method leads me repeatly do above when edit a file in project.

So an idea comes to me, why not create a script to do above automatically?

Refer to Blog for django code completion in vim, this is exactly what I think, but I encounter a problem during my configuration.

Fail one below:

1. create a script in /usr/bin named vim_wrapper

   #!/bin/bash

   export PYTHONPATH="${PYTHONPATH}:/path/to/myDjangoProject/"

   DJANGO_SETTINGS_MODULE="/path/to/myDjangoProject/settings" vim $@

2. Add alias in ~/.bashrc

   alias vi="vim_wrapper"

Restart terminal sesstion, command vi /path/to/myDjangoProject/urls.py, make a test :python from django import db, an Error happen says:

ImportError: Could not import settings
‘myDjangoProject/settings’ (Is it on
sys.path?): Import by filename i s not
supported.

I don’t know how to solve this. Thanks for help.

Answer 1

Create the vim_django executable script in /usr/bin

Content in vim_django script:

#!/bin/bash

PROJECT=`python -c "import os; print os.getcwd().partition('Solutions')[2].split(os.sep)[1]"`
export PYTHONPATH="${PYTHONPATH}:/path/to/django-projects-parent/"
DJANGO_SETTINGS_MODULE=$PROJECT.settings vim $@

Type vim_django urls.py(or other files) to edit in django project, Ctrl-x & Ctrl-o for code completion.

NOTE: In PROJECT settings, you may notice Solutions that is parent directory of all my django projects
