How to access current_user in side custom controller?

[MontyTHall]

I can't do this:

module AdminController

using GenieAuthentication, Genie.Renderer, Genie.Exceptions, Genie.Renderer.Html

function index()
  authenticated!()

#  h1("Welcome Admin") |> html
   current_user().name
end

end

But in a routes.jl file I can do this

route("/auth") do
    current_user().name
end
