[Catalyst] Optional path prefix

I'd probably myself want some plack middleware that would convert



/account/<id>/widget/<id>    with accept type application/mycompany.v1+json

But you could probably support changing the URL path pretty easily with either setting the controller namespace to have v1 in it, or adding a root tot he change that specifies the new extra path part.

I understand the development word seems to prefer making version part of the path.  depending on your logic and the type of changes introduced it may or may not be easier to take one approach or the other.

Over in this thread was a discussion on API versioning and implementing via Accept: headers vs. adding a version in the URL.   Looks like using a version in the URL is winning.

We have existing chained actions that might look like this:


If want to migrate to a new version scheme in the URL like this:


This would be the same action chain as the first path -- and both would work at the same time.

Is there any way to support both actions via Chained dispatching?   Or will I need a role that looks for that pattern and strips it of the request during prepare_action?

I've done something similar in the past where I added a language tag at the start of every path:


I strip that off and then update $c->req->path for dispatching.

Again, I'm in the Accept: header camp for versioning, but I'm finding more and more discussion on using URLs.    There's an e-book that seems to be cited often. I'd be interested in other's view on that book -- it seems written from a practical Rails programmer point of view instead of a REST purist view.   There's a lot in that e-book I don't really agree with (plural nouns?), but the practical usage seems to be winning out.  Hope it's not a mistake in the long run.
