I use very often in my code (and I don't know if I'm right to use it):

{{#each model.posts as |post|}}

  <div>post.title</div>

{{else}}

  <div>I'm loading the posts...</div>

{{/each}}

and until today everything OK.

But now I don't know if the model.posts is empty or not.

How to show an error instead of loading forever an empty array?
