Go + Revel: How to import custom package?

I am following tutorial of chat room covered here

I changed it to import a local package instead of using the sample from ravel's github. I changed it into something like this in one of the controllers (refresh.go in the tuts):

import (
	"./../chatroom"
	"github.com/revel/revel"
)

And chatroom was in the right directory:

- app
  - chatroom
    - chatroom.go
  - controllers
    - refresh.go
    - app.go

package chatroom was also initialized already in chatroom.go.

But when running the code, I received this error:

The Go code app/tmp/main.go does not compile: local import "./../chatroom" in non-local package

What am I doing wrong here?

It would be best, following this answer to not use a relative path, but a path from the $GOPATH/src

In your case, is $GOPAHT/src includes app chatroom, you would use

import app/chatroom

The OP comments:

> working, but I have to include my app name, something like myapp/app/chatroom,

That makes sense, if $GOPATH/src contains the folder myapp.
