package_dir = os.path.abspath(os.path.dirname(__file__))
db_dir = os.path.join(package_dir, 'nd_slack.db')
# NEED 4 /'s to specify absolute for sqlalchemy!
# ex: sqlite:////asdfaijegoij/aerga.db
# NEED 3 /'s for relative paths
# path has a / at the beginning so we have 3 here
SQLITE_DB = ''.join(['sqlite:///', db_dir])
