great code, thx its running perfect.
But I first had to get the right rails version with: gem install -v=1.1.4 rails –include-dependencies,
because gem didn’t get through the XP firewall i had to install a new firewall ( ashampoo free version ) and disable the windows firewall ( reboot necessary)
then rake db:migrate threw an access denied error, so i blanked out the password in the database.yaml file for the test&developement environment … finally got it running

When I tried to run this, I get an exception (below)]
when connecting in after a fresh install (have db setup
etc).

I’m running Ruby v1.8.4 with Rails 1.1.6

You have a nil object when you didn’t expect it!
The error occured while evaluating nil.has_parent?

Well, i just provided the tree with the minimum features, just to show the awesome approach of rails towards the web development to the users who are still stuck to php stuffs and thereby i am giving a sample application for more ease of feeling amazed out of rails and specifically towards implementing ajax.

Definitely i will love to help for the things which i feel to be helped to a fresher to rails.

Of-course the thigs what you are asking like .. ADD, EDIT DELETE etc… and switching off the DRAG-DROP are just a kids play if you are fluent enough with rails development. But as you said that you are new to rails so you can take it as a good assignment to furnish your rails, coz even a fresh rails developers can do it within 1-2 days.

I must suggest you to do all these things yourself make your tree better.

I’m very new to rails; but I like what I see. I got your demo running in a few minutes. The following may be obvious to more experienced users.

I noticed if an item from the root is dragged under another item, there is no way to put the item back in the root. Perhaps a root icon is needed?

Is there an easy way to combine this with the scaffold generator so there is CRUD forms integrated into the tree? I’d like to be able to click ADD, EDIT, VIEW, and DELETE and have the appropriate form be displayed to the right of the tree based on the item selected on the tree.

Finally, can I toggle the drag and drop feature off?

I think i will try to add in place editor function, a create function, and a file-browser-like view.

Notice i’ve said “try to” lol ;=)

Thanks.
