findOne based on route

1. /api/:owner/:repo
2. [{commit: '4asd56f4asd56f4asd65f', message: 'Commit message 1'}, {commit: 'df4saf54d6safd54asf6', message: 'Commit message 2'}]

1. /api/:owner/:repo/:commit
2. {commit_id: '4asd56f4asd56f4asd65f', message: 'Commit message 1', author: 'Frank'}

For this I have a Model:

1. findAll: 'GET /api/github/{owner}/{repo}'
   
2. findOne: 'GET /api/github/{owner}/{repo}/{commit}'

Now I want to show this data depending on the URL (e.g. /frk/repo1/ shows a list of commits, /frk/repo1/4asd56f4asd56f4asd65f shows details about one commit).

I have an app state object where I define a get function for 'commits' based on the owner and repo:

1.     commits: {
         get: () ->
           new Commit.List {
             owner: this.attr('owner')
             repo: this.attr('repo')
           }

The template for the repo prints a list of commits with links to the commits themselves. This works great so far, I get a list of commits, when I clock on a link I listen for the route event in a Commits component and change the template that is shown to:

1.     events: {
         "/:owner/:repo/:commit route": (data) ->
           $('#app').html(can.view('views/commit.mustache', {}))
       }
   

How do I load the details for a single commit? Is it best to add this to the app state similar to the commits definition? Do I call the findOne function manually, and how do I return the correct value?

1.     commitDetails: {
         get: () ->
           Commit.findOne {
             owner: this.attr('owner')
             repo: this.attr('repo')
             commit: this.attr('commit')
           }
       }

I'm sure there is a simple answer for this, but I haven't found any example and from the docs I can't see the best way to do this. Thanks in advance :).
