[Proto-Scripty] sortable tree in rails
Hi,
I'm a new member to this group, and would appreciate some help with
using Sortable in Rails.
How do I generate a sortable tree like this with RoR?
http://script.aculo.us/playground/test/functional/sortable_tree_test.html
Specifically, the ability to drag a section and its children to
another position.
I'm using this code currently:
<%= sortable_element("articles", :url => "sort", :constraint
=> :vertical, :tree => true) %>
And with a tree rendered like this:
- Section 1
- article 1
- article 2
- article 3
- Section 2
- article 4
- Section 3
- article 5
- article 6
If I drag on Section 3, only Section 3 moves, article 5 & 6 don't go
along with it. Is there any trick?
Thanks,
Robert

I figured out what I was doing wrong. I had the tag around
Section name. If I put the tag around Section and its
children, the children move along with the parent.

[Proto-Scripty] TypeError: Value undefined (result of expression Element.insert) is not object.
Hi, Intermittently, I get a browser popup error that says: RJS error: TypeError: Value undefined (result of expression Element.insert) is not object. My suspicion is that since included javascripts are loaded asynchronously, sometimes prototype.js doesn't finish loading before the page.insert_html is called. Does it sound right? If so, I suppose the solution involves testing whether Element.insert is defined, and if not, wait a little while and test again. What's the best way to do this as there's no sleep() in javascript? Any assistance is appreciated. Thanks, Robert --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.

Hi david, I don't have an example to show you, and it happens so randomly. FWIW, I'm loading prototype on-demand with element.appendChild(), which probably complicates things a little. I just found reference to setInterval() in Javascript, will look into that to see if it fits my needs. Thanks.
