todo-route.js

import Ember from 'ember';

export default Ember.Route.extend({
    model: function() {
        return this.store.find('todo');
    },
    actions: {
        // Additional lines truncated for brevity...
        acceptChanges: function(todo) {
            if (Ember.isEmpty(todo.get('title'))) {
                this.send('deleteTodo', todo);
            } else {
                todo.save();
            }
        },
        deleteTodo: function(todo) {
            todo.deleteRecord();
        }
    }
});

Would it be better to handle the delete in the todo-item component? For example:

acceptChanges: function(todo) { // todo is todo.title
    this.set('isEditing', false);
    if (todo === "") { 
        this.sendAction('deleteTodo', this.todo);
    }
},

...and remove acceptChanges entirely from the route.

Also it looks like the input helper is saving any changes so todo.save(); might not be required?

Hi, in Edit and Delete Todos section todoRoute is not generated with cli. It is later, in Child Routes.
