Jifty::Manual::TutorialRest(3) 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.


You must add this to your site_config.yml

      - 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.


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.


Just list the models.

  $ GET http://localhost:8888/=/model.yml
  - MyWeblog.Model.Post

List the Post schema.

  $ GET http://localhost:8888/=/model/Post.yml
    label: Content
    name: body
    readable: 1
    sort_order: 1
    type: text
    writable: 1
    mandatory: 1
    name: id
    readable: 1
    type: serial
    writable: 0
    default: Untitled post
    label: Title
    name: title
    readable: 1
    sort_order: 0
    type: text
    writable: 1

You did make some posts, right?

  $ GET http://localhost:8888/=/model/Post/id.yml
  - 1
  - 2

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


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
  POST http://localhost:8888/=/model/Post/id/3.yml --> 404 Not Found
