The code seems to work perfectly in the browser either way. The order of the declarations only affects the result of the tests. It took me a while to find this problem by going back over Hartl's code and making sure mine exactly reflected his. I found this order difference after a while and made the change, and suddenly my tests all passed. I've switched the order back and forth several times to make sure it is the order and only the order that is changing and that is making the difference. I'd like to understand so I'm not caught on a similiar problem when I am writing my own code rather than copying someone else's code.

A:

It looks like in this controller, signed_in_user is acting as a guard to make sure that there is a valid current_user before proceeding (and if there isn't one, redirecting to the signin page, where one will be created).
Your fourth test gives this away - admin? is undefined because admin_user was called before signed_in_user. When signed_in_user is called first, admin_user won't be called unless there is actually a valid current_user to call admin? on. So there actually is a dependency on the order of filters here - signed_in_user must be called first, because it ensures that there is a valid current_user, and the other filters assume that this has happened already.

Couchbase & nodejs: View query with range, order and limited results

                 only: [: exponent, : edit, : update, : destroy, : following, : followers ]
