  @createFromFacebook: (session, accessToken, fbUserMetadata, promise) ->  # '@'を忘れないように。

    name = fbUserMetadata.name

    @.create
      name: name
      email: email
      userId: userId

    session.userId = userId
    session.save()
    promise.fulfill userId

" # '@'を忘れないように。"

Loose translation:
So that it doesn't forget '@'.
