Getting absolute paths for loading resources?

From:: Michael Fogleman
Date:: 2011-08-13 @ 01:42

I wrote myself a simple helper function:

def path_for(app, path):
    return os.path.join(app.root_path, path)

Example usage:

app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///%s' % path_for(app,
'database.db')

I use it for loading resources from disk, relative to the app
directory. My question is - have I reinvented the wheel? Is there a
conventional/better way of doing this in Flask?

Thanks,
Michael

Flask-SQLAlchemy is automatically relative to the app root by default.
Just leave the 4th slash out.  For opening files for reading there is
app.open_resource.

However with the introduction of instance folders I am considering
changing Flask-SQLAlchemy to be relative to the instance folder.
