How do rewrite the model part of this tutorial so i stop having this depreciation warning in the console?

"DEPRECATION: Using the context switching form of {{each}} is deprecated. Please use the keyword form ({{#each foo in bar}}) instead. See http://emberjs.com/guides/deprecations/#toc_more-consistent-handlebars-scope for more details."

My problem is how do i make the model avilable in the view with variable name other than model because i don't think it's good pratice to have {{#each post in model }} or {{#each comment in model }} i would like to use comments and postsinstead of model?

You can use either:

{{#each model as |post|}}
<!-- OR -->
{{#each post in model}}

From what I've read it doesn't look like it's possible to alias the model. This is an example of convention over configuration. (Please let me know if I'm wrong, since I also prefer the comment in post syntax)

Thanks Michael Dvorscak and exuper okouya for the hints. I got it working with model with Ember 1.9.0. I see that this probably is an example of convention over configuration but still wonder why the examples in the Ember Deprication List give examples like:

{{#each person in people}}
  <p>{{person.firstName}} {{person.lastName}}</p>
  <p>{{person.address}}</p>
{{/each}}

Can someone clarify why 

{{#each post in posts}}

won't work in our Dracula app?

I was able to get this working in 1.10 using:

{{#each post in model}}
   <li>{{post.title}}</li>
{{/each}}
