setting up hasOne relationship GeddyJS

Question

I'm trying to expand on the GeddyJS Todo tutorial from their site. I've added another model, Project, to the Todo project, and would like to set up a relationship between Todo and Project in a Todo-hasOne-Project manner.

Here's the code from my create controller method where I attempt to set the relationship up after the Todo item is saved:

todo.save(function(err, data) {
        if(err) {
            params.errors = err;
            self.transfer('add');
        } else {
            geddy.model.Project.getProjectById(todo.parent, function(err, project) {
                if(err) {
                    params.errors = err;
                    self.transfer('add');
                }
                else {
                    todo.setProject(project);
                    self.redirect({ controller: self.name });
                }
            });

        }
    });

I'm using a class method (getProjectById) that takes the todo's parent property (Project's id) to fetch the project from the db.

In my Todo class file, I have the hasOne relationship defined as follows:

this.hasOne('Project');

I keep getting compiler errors that read:

c:\Program Files (x86)\nodejs\node_modules\geddy\node_modules\model\lib\index.js:254
            throw new Error('Item cannot have a hasOne/hasMany association ' +
                  ^
Error: Item cannot have a hasOne/hasMany association if it is not yet saved..

Finding by-example documentation has proven difficult, so I thought I'd ask the strongest community on the web.

Anyone know what I'm missing?

Are you still experiencing this issue? If so can you try running

$ npm update -g geddy

This will most likely fix your issue.
