This AuthenticatedRouteMixin makes /artists/163/similarities redirect to the login page when the user isn't authenticated. However, after login the user is taken to the homepage instead of back to the previous /artists/163/similarities page. I'm not sure how to fix that yet.

I'm trying to get the /artists/163/similarities page to work.

I want the form rows to work like so:

1. Similarities will be saved to the server as the user types (already works for existing models via PUT)
2. There should always be one blank row at the end representing a new similarity. If the user enters data it should be saved to the server and a new blank row should be added.

An example of how it should work: http://jsfiddle.net/treyh/kfffyqup/

Part 1 works already but part 2 doesn't work yet.

The tests haven't been updated/added, but this seems to work now. You can get to artist pages by clicking the pencil icon in the top right of an artist's search result listing. From that page there's a link to a page for adding/updating your artist similarity ratings (you need to be logged in for that).
