Just to chime in, this is related-but-not-quite,
I've been working off and on on a little library for Rails-style
RESTful controllers. It's called "Sleeping Bag":
http://code.google.com/p/sleepingbag
It's not quite ready yet, so don't expect it to work well, but I
thought maybe someone would find it interesting. It basically just
maps HTTP actions and the stuff in the path to methods on your
controllers. You could have a controller like this:
class Planes < R '/planes', '/planes/([^\/]+)', '/planes/([^\/]+)/([^\/]+)'
include SleepingBag
def index
@planes = Plane.find(:all)
render :planes_index
end
def show(id)
@plane = Plane.find(id)
render :show_plane
end
end
"GET /planes" and "GET /planes/747" are mapped to the index and show
methods, respectively, based on the methods' arity and the fact that
index and show are defined by default to be "standard actions", those
represented by just an HTTP method, not an aspect. (I'm doing aspects
without semicolons, like Rails now is.)
Aspects and other standard methods are defined by defining methods,
mapped to GET by default. So, to continue with the Planes
controller...
def wingspan(id)
@plane = Plane.find(id)
render :plane_wingspan
end
This would map to "GET /planes/747/wingspan". To fly a plane:
methods[:fly] = [:post]
def fly(id)
@plane = Plane.find(id)
@plane.fly!
"Bon voyage!"
end
This means that only "POST /planes/747/fly" will call the fly action.
I want to make declaration of controllers simpler, like this:
class Planes < ZZZ
def index
# ...
end
# ...
end
Coming soon, possibly...
