ok, finally made it.
who ever ends up here as desperate as I was: If you use a current version of phoenix… forget about all that strange alias settings you can find at stack-overflow and you also don’t need to do that strange black magic they did at the elixirforum.
No. It’s actually much easier. It is all about that new functions which come along with that HEEx and ~H stuff. Just use the link/1 function. . I did it like this:
<.link patch={~p"/guess"}>new game</.link>
and that’s it. Good luck!
