Can anyone get the install process to actually work? I got to 'python manage.py installdb' and it failed because that command doesn't exist in manage.py. I tried a bunch of the other commands from manage.py help as well and still nothing.

I had to install MySQL-python, but now I'm stuck on a foreign key conflict when importing the initial data.json file.

    IntegrityError: (1452, 'Cannot add or update a child row: a foreign key constraint fails (`treeiodb`.`core_user`, CONSTRAINT `user_id_refs_id_4bf8d20` FOREIGN KEY (`user_id`) REFERENCES `auth_user` (`id`))')

Please have a look at the issue tracker, there is an easy fix.

Just run: mysql -u username -p -D database < sql/mysql-treeio-current.sql

That would've been easier :) I ended up manually checking the order in which the data in the json file was inserted and fixing that.

I've updated the README to include this.

It sounds as if maybe your pythonpath isn't set up correctly. Try

export PYTHONPATH=$PYTHONPATH:/path/to/treeio:/path/to/

(ie add the project path and its parent to PYTHONPATH), then try manage.py installdb again.

NB This is guesswork based on prior django experience, I haven't actually tried installing it.

It's a Django project, so the command might be "syncdb" instead. If that doesn't do the trick, they'll have installed a custom management command that doesn't seem to get picked up. Grep the source code for installdb then.
