I think this is a great idea! I don't think it should be limited to only the authenticaton or `_user` fields though. We can generalize this pattern for other galaxy objects to reduce repeated code in the view (in particular, getting the `game` object comes to mind. More often than not, we need more information about a `game` from its `slug`)

My bad for hijacking this pull request; I should have opened a new issue for this. Should we open a new issue and continue this discussion?
