alias in elixir

This post will not explain about alias , rather I would like to share a piece of code that caught me off guard.

alias Rumbl.Accounts # context
alias Accounts.User # schema

def first_name(%User{name: name}), do: name

If I compile it, it would give me compilation error Rumbl.Accounts.User__struct__/0 is undefined.

It's pretty obvious why, looking at the code now. Since the Rumbl.Accounts is already aliased, the Accounts.User assumed Accounts to be Rumbl.Accounts.

Just updating their position would fix it
