How to keep belongsTo and hasMany linked?

1

So basically I have a project model which has many todos 0…n:

App.Project = DS.Model.extend({
  title: DS.attr('string'),
  date: DS.attr('date', {defaultValue: null}),
  tag: DS.attr('string', {defaultValue: null}),
  todos: DS.hasMany('todo', {async: true})
});

and a todo model which belongs to a project 0…1:

App.Todo = DS.Model.extend({
  title: DS.attr('string'),
  date: DS.attr('date', {defaultValue: null}),
  project: DS.belongsTo('project', {async: true})
});

So I can simply get which project todo belongs to :

{{#each todo in model}}
     {{todo.title}}
     {{todo.project.title}}
{{/each}}

and set which project todo belongs to :

var todo = this.store.createRecord('todo');
this.store.find('project', 1).then(function(project){
  todo.set('project', project);
  todo.save();
});

But how do we keep the other side ( the project model ) to have the todo in it hasMany attr?

Do we need to set in the project model, or is there any method in keeping them async?

Hi, did you ever solve this? I’m having the very same issue atm and am stuck clueless.
