How to access current_user in side custom controller?

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
```
