NAME
Jifty::Manual::TutorialRest - Web Services

This builds on Jifty::Manual::Tutorial, so make sure you have a running jifty that roughly resembles the step-by-step from there.
SETUP
You must add this to your site_config.yml
framework:
Plugins:
- REST: {}
See Jifty::Plugin::REST.
The commands assume that you have LWP installed with the GET alias. If not, you'll need to use the longhand lwp-request -m GET, or curl,
or your browser.
help
Make sure it is working:
$ GET http://localhost:8888/=/help
Accessing resources:
...
You should see some text describing the services, not html (that's longhand for 404.) Check the config and restart the server.
GET
Just list the models.
$ GET http://localhost:8888/=/model.yml
---
- MyWeblog.Model.Post
List the Post schema.
$ GET http://localhost:8888/=/model/Post.yml

Dump the data:
$ GET http://localhost:8888/=/model/Post/id/1.yml

body: 'This is my post, the content of which is this, which is mine.'
id: 1
title: my first post
$ GET http://localhost:8888/=/model/Post/id/2.yml
---
body: "Content of another post. Got to go, the cat's on fire."
id: 2
title: post deux
POST
TODO not working
Actually, it looks like it is not supposed to work this way. Why not?
$ echo '---
body: "A post via web services"
id: 3
title: "posting from the command-line"
' | lwp-request -m POST http://localhost:8888/=/model/Post.yml
