Hi. My question: How can I use Rails-Client to consume scaffold-generated web services on Heroku?
I created a very simple REST application on Heroku ( restnotes.herokugarden.com) script/generate scaffold note body:text priority:integer rake db:migrate The application is accessible through http://restnotes.herokugarden.com/notes I am able to create notes through http://restnotes.herokugarden.com/notes/new and the form-generated HTML looks like this: <form action="/notes" class="new_note" id="new_note" method="post"><div style="margin:0;padding:0"><input name="authenticity_token" type="hidden" value="92c28cfca4a291126c4d5622611e9132a0d3e0d5" /></div> <p> <label for="note_body">Body</label><br /> <textarea cols="40" id="note_body" name="note[body]" rows="20"></textarea> </p> <p> <label for="note_priority">Priority</label><br /> <input id="note_priority" name="note[priority]" size="30" type="text" /> </p> <p> <input id="note_submit" name="commit" type="submit" value="Create" /> </p> </form> Now I would like to use a rest-client 0.9 to interact with my notes application.

C:\Users\Jay>irb irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'ActiveResource' => true irb(main):003:0> class Note < ActiveResource::Base irb(main):004:1> self.site='http://restnotes.herokugarden.com' irb(main):005:1> end => "http://restnotes.herokugarden.com"; irb(main):006:0> irb(main):007:0* irb(main):008:0* I was able to use it to find existing notes: irb(main):009:0* Note.find :all => [#<Note:0x5a5d1b0 @attributes={"updated_at"=>Thu Feb 26 19:35:57 UTC 2009, "body"=>"test", "priority"=>3, "id"=> 3, "created_at"=>Thu Feb 26 19:35:57 UTC 2009}, @prefix_options={}>] I then used it to successfully create a new note with POST (through ActiveResource). irb(main):010:0> new_note=Note.new(:body=>"ActiveResource client test note", :priority =>"5") => #<Note:0x5a57d3c @attributes={"body"=>"ActiveResource client test note", "priority"=>"5"}, @prefix_options={}> irb(main):011:0> new_note.save => true A look at the web interface showed that the new note was created. Then I modified it: irb(main):012:0> new_note.body="There are monkeys on mars" => "There are monkeys on mars" irb(main):013:0> new_note.priority="99" => "99" irb(main):014:0> new_note.save => true irb(main):015:0> The PUT worked as well to change the values of the note. At this point, I'm at a loss because I have no idea how to use Rest-client to POST new notes or to change (PUT) the fields for this scaffold-generated resource. Can anybody help?
