Update these two models so that a person has many puppies, and a puppy belongs to a person. Bummer! There was an error with your code: SyntaxError: Parse error

what am i doing wrong?

js/app.js 
AnimalShelter = Ember.Application.create();

AnimalShelter.Person = DS.Model.extend({
  name: DS.attr(),
  puppies: DS.hasMany('puppy', {async: true}); 
})

AnimalShelter.Puppy = DS.Model.extend({
  name: DS.attr(),
  person: DS.belongsTo('person', {async: true});
});
index.html

Hi Andrew, it looks like the issue is you have semi-colans at the end of the lines containing puppies: and person: , if you remove them the code should work :) for example:

  puppies: DS.hasMany('puppy', {async: true}) //removed semi-colan

Hope that helps!!

I am also having the same issue. I've checked other forum posts and I'm still getting the same error in the challenge " Bummer! There was an error with your code: SyntaxError: Parse error". Is it possible that there is a bug?

Here is the code I used for the challenge:

AnimalShelter = Ember.Application.create();

AnimalShelter.Person = DS.Model.extend({
  name: DS.attr()
  puppies: DS.hasMany('puppy', {async: true})
});

AnimalShelter.Puppy = DS.Model.extend({
  name: DS.attr()
  person: DS.belongsTo('person', {async: true})
});

I figured it out. I was missing the comma after DS.attr( ) in both lines. It's always the little things.
