Wrong answer for model challenge

The challenge asks "We've set up a router with a couple resources for you, as well as a puppies variable with some model data. Create a puppy route that loads the correct puppy based on the ID in the URL."

Here is the answer I gave, but it says it is wrong. The alert says I need to pass the post_id into the second argument. Shouldn't it be puppies_id like I had put?

AnimalShelter = Ember.Application.create();

AnimalShelter.Router.map(function() {
  this.resource('puppies', {path: '/'});
  this.resource('puppy', {path: 'puppies/:puppy_id'});
});

var puppies = [
  {id: '1', name: 'Miss Puggy'},
  {id: '2', name: 'Pugsley Addams'},
  {id: '3', name: 'Chicken Pug Pie'}
]

AnimalShelter.PuppyRoute = Ember.Route.extend({
  model: function(params) {
    return puppies.findBy('id', params.puppy_id);
  }
});

Hi Steven! Thanks for the heads up. Your solution is, indeed, correct. It looks like the challenge isn't set up properly. I've asked Treehouse to help out with getting that fixed. Thanks for finding the problem and pointing it out!

I hope you're enjoying the course so far.

Here's the answer to the kittens question below:

Question: In app.js, we've set up a variable named kittens with some data in it. Set up KittensRoute to use this data for the model.

Answer:

AnimalShelter = Ember.Application.create();

AnimalShelter.Router.map(function() { this.resource('kittens', {path: '/'}); });

var kittens = [ {id: '1', name: 'Meowzer'}, {id: '2', name: 'Squeaky'}, {id: '3', name: 'Fluffy'} ]

AnimalShelter.KittensRoute = Ember.Route.extend({ model: function() { return kittens; } });

Hey Steven Byington!

You're right—we had a bug in the code challenge. Your solution (the correct solution) is now properly accepted. Try again and all will be right in the world.

I also awarded you the Exterminator badge for being awesome and squashing bugs.

Kyle Meyer It does not appear to be working yet. As my code below appears to be the same and is failing.

AnimalShelter.PuppyRoute = Ember.Route.extend({
  model: function(params) {
    return puppies.findby('id', params.puppy_id);
  }
});

I had the same result using the code examples from the video. The trick is to use findBy instead of findby.

Since this was from 3 months ago, I assume you figured it out by now. However, for anyone else that might be your problem.
