Donald posted a lovely, concise recommendation (on rest-discuss)
about how to structure REST URLs which looks *remarkably* like what
Rails does (or will do, or maybe ought to do :-) by default. He
gave me permission to share it here, and I've added it to the wiki:
http://microformats.org/wiki/rest/urls
I like that. The only slight problem is how to automate the singular/
plural distinction. The current rules for a REST look are:
map.connect ':controller/:action', :action =>
'index', :requirements => { :action => /[^\d]+/ }
map.connect ':controller/:id', :action => 'show', :requirements
=> { :id => /[\d]+/ }
map.connect ':controller/:id/:action'
But that will either translate into widgets/ or widget/ -- not both.
It would probably take a Routing patch to figure out a way to
represent it all succinctly. Or, you could of course also just use
the power of Ruby:
for entity in %( posts comments authors )
map.send entity, "#{entity}/:action", :action =>
'index', :requirements => { :action => /[^\d]+/ }
map.send entity.singularize, "#{entity.singularize}/:id", :action
=> 'show', :requirements => { :id => /[\d]+/ }
map.send entity.singularize, "#{entity.singularize}/:id/:action"
end
And riddle me this, we could wrap it up in this extension:
Module RestRoutes
def connect_entity(entity)
entity = entity.to_s
collection = entity.pluralize
named_route(collection, "#{collection}/:action", :action =>
'index', :requirements => { :action => /[^\d]+/ })
named_route(entity , "#{entity}/:id", :controller =>
collection, :action => 'show', :requirements => { :id => /[\d]+/ })
named_route(entity , "#{entity}/:id/:action", :controller =>
collection)
end
end
ActionController::Routing::RouteSet.send :include, RestRoutes
...which would then allow you to do:
ActionController::Routing::Routes.draw do |map|
map.connect_entity :post
map.connect_entity :comments
end
I see the makings of a RESTifarian plugin shape up quickly ;)
