You can add a function in the Articles.Post (or something like that) module which would return the ordered results.

The index action in the controller then becomes

def index(conn, _params) do
  bydesc = Articles.Post.fetch_ordered(desc: :inserted_at) # or is it just Articles.fetch_ordered/1?
  render(conn, "index.html", bydesc: bydesc)
end

The function in Articles.Post can be something like

def fetch_ordered(constraint) do
  Post |> order_by(constraint) |> Repo.all()
end

The point of phoenix 1.3 is moving this kind of logic out of the web layer and into the domain layer, I guess. There are quite a few threads around here discussing it.
