Newbie: using external project, but not touching it. Confused about how to layout my directories, autocomplete not working

Hi,

I am writing addons for Odoo (a large product - on github -written in python) as part of another project. My own project is oalso in git, odoo extensions are a small part of my own project.

I am confused on how to layout my project directories in PyCharm.
My own projects is structured like this:

project
project/c-programs
project/odoo-addons/addon-1

Now I need PyCharm to search Odoo sources (for autocompletion etc), so I've done the following:

pycharm-project-base\odoo\.git
pycharm-project-base\myproj\.git

It does seem to search everything but does not autocomplete odoo-stuff.

Does that fact that I have two git projects in one project have to do with anything?

Also of course I'd like to commit and push for my own project, but odoo I'll only need to pull.

Thanks,
Ron
