PathPrefixed Subrouter with individual handlers

Given the following (complete example at Go playground):

// Collection
root := r.PathPrefix("/widgets/").Subrouter()
root.Methods("POST").Handler(h.Create)

// Individual
object := root.PathPrefix("/{uuid}").Subrouter()
// ~neither: object := root.PathPrefix("/{uuid}").Subrouter() 
object.Methods("GET").Handler(h.Show)
object.Methods("PUT").Handler(h.Replace)
object.Methods("DELETE").Handler(h.Delete)

// Relationships
object.Methods("GET").Path("/foos").Handler(eh.Foos)
object.Methods("GET").Path("/bars").Handler(eh.Bars)

I would have expected the following URLs to trigger the respective handlers, but I can't seem to make it work:

✔ POST /widgets          => h.Create
✔ GET  /widgets/123      => h.Show    (assumes PathPrefix('/{uuid}'))
✔ GET  /widgets/123/     => h.Show    (required if 'PathPrefix('/{uuid}/')')
✖ GET  /widgets/123/foos => h.Foos    (actually routes h.Show)
✖ GET  /widgets/123/bars => h.Bars    (actually routes h.Show)

Unfortunately neither of the last two are apparently routable, they both trigger h.Show, can anyone point out what I'm doing wrong? I might have expected that having an unbounded {uuid} (without the trailing slash) could have run-on, ignoring the / but that doesn't seem to be the case.

I don't even know if this has to do with the Subrouter strict-slash issue which is still open on Github (#31), but to the best of my understanding I did try the alternatives there. (i.e object.Methods("GET").Path("/").Handler(h.Show))

Could the Handler mounted on the object root via Methods() prevent any further routes matching?

The problem was that gorilla/mux fires the first matching handler. That's important the first matching handler.

That means that routes logically under /{id}/ are never found, since the routes that would match them are matched first by the parent handler.

Changing the code to the following makes it work as expected:

// Collection
root   := r.PathPrefix("/widgets/").Subrouter()
object := root.PathPrefix("/{uuid}").Subrouter()

// Relationships
object.Methods("GET").Path("/foos").Handler(eh.Foos)
object.Methods("GET").Path("/bars").Handler(eh.Bars)

// Individual
root.Methods("POST").Handler(h.Create)
object.Methods("GET").Handler(h.Show)
object.Methods("PUT").Handler(h.Replace)
object.Methods("DELETE").Handler(h.Delete)

Then things work perfectly.
