NY, well, you should look in your railsapp/log/production.log file.
It should say something like ActionController::RoutingError (No route matches "/get_nodes.json" with {:method=>:post}):
Well, the best solution would be to try TreeLoader({dataUrl : 'get_nodes.json', requestMethod : 'GET'}).
Note that the requestMethod will be GET.
I think that should help,

2008-06-24T08:36:00.000-04:00

In console of my local webrick
"POST /get_nodes.json HTTP/1.1" 404 622

http://localhost:3000/main.html -> /get_nodes.json

And when I upload my project to a free host (in firebug console,it's nginx) and get 405

I put all html,javascriprt and json files in the rails public folder,is it wrong?

Can you give me a example by use treeLoader with Rails?

NY, look in your console where you opened the webrick from, it should tail your development log and which should tell you a more specific error message than just error 405...
I hope that helps,

Good article!
Now I start a project by Rails2.1 & Extjs2.1
But I have a problem.
I want to load a static JSON file
such as "tree.json"

TreeLoader({dataUrl : 'get_nodes.json'})

It can work with PHP and by set MIME it also can work with ASP
But by use webrick, have a http 405 error.
How can I do it with Rails?

Thanks

Hey kain,
you're right, my last comment was a little confusing and Rails 2.1 really turns the new "root feature" on by default IF you create a new rails app. I didn't create a new rails app with "rails appname". I only updated an existing rails app. That's why I didn't have the new_rails_defaults.rb file which sets the root feature to true and is only created when you run the "rails appname"

mm.. I think I got it, set new options to false AND customize render :json options :)

hi Steffen,
it's strange, I found out that creating a new 2.1 rails app uses the new defaults to true (check initializers/new_rails_defaults.rb) and must be turned off to false.

at this point I had to manually modify the way json data is returned by default (with settings to false) and create a new mimetype (just ext scaffold plugin does) to work with ext grids.

I'm still a

Kain, I was disappointed by this change as you were.
As I said in the blog post, turning ActiveRecord::Base.include_root_in_json on is not helpful. It's good that it is turned off by default, though.
I converted a Rails 2.0.2 project just last week (to use the named_scope feature) by only changing the gem version in the environment.rb file, and so far everything including my ext js still

I just started with Rails 2.1 and Ext.. I'm disappointed :(

however I get different results about the data "root", with false no root, with true every element have the root, but no "super plural root".

ActiveRecord::Base.include_root_in_json = false
[{"updated_at": "2008-06-17T23:05:15Z", "language": null, "body": "test", "id": 1, "created_at": "2008-06-17T23
