Sortable acts_as_tree with heirarchy

I’ve been stumbling on the tut at oriontransfer
(http://wiki.oriontransfer.co.nz/main/show/SortableTree)

I’ve got it working in a one dimensional list and I’ve got the drag and
drop working on children, but as can’t get it to save the tree.

Here’s my view:

Menu Prototype 2

<%= flash[:notice] %>
    <% @navigation.each do |link| %>
  • <%= link.name %>
      <% link.children.each do |child| %>
    • <%= child.name %>
    • <% end -%>
  • <% end -%>

<%= sortable_element ‘menu’,
:url => { :action => “sort”, :id => @navigation },
:complete => visual_effect(:highlight, ‘menu’), :tree => true
%>

Here’s the action:

def change_hierarchy
change_links params[:menu]
end

def change_links (links_hash)
  parent_id = links_hash[:id] || Link.root.id

  links_hash.each do |key, value|
    next if key == "id"

    link = Link.find (value[:id])

    link.display_order = key
    link.parent_id = parent_id

    link.save

    change_links value
  end
end

Does anyone have a clue what’s my mess?

Hola,

He echo una adaptacion de tu codigo, a mí me funciona:

Mi condicion de categoria principal: (category.parent_id == nil)

Mi partial(_categories.html.erb):

    <% @categories.all(:order => "show_order asc").each do |category| %> <% content_tag_for :li, category do %> <%= image_tag "drag.png" %> <%= link_to category.name, blog_category_path(@blog.permalink, category.permalink)%> (<%= category.posts.size%>)
      " style="list-style:none;"> <% category.children.all(:order => "show_order asc").each do |sub_category| %> <% content_tag_for :li, sub_category do %> <%= image_tag "drag.png"%> <%= link_to sub_category.name, blog_category_path(@blog.permalink, sub_category.permalink)%> (<%= sub_category.posts.size%>) <% end %> <% end %>
    <% end %> <% end %>
<%= sortable_element 'categories', :url => sort_blog_categories_path(@blog.permalink),:complete => visual_effect(:highlight, 'categories'), :handle => "handle", :tree => :true, :update => "nav_zone" %>

Mi controlador:

def sort

i_sort params[:categories]
@categories = @blog.categories.root
render :partial => "categories/categories.html.erb"

end

def i_sort(categories_hash )
parent_id = categories_hash[:id] || nil
puts categories_hash.to_a.to_s rescue puts categories_hash.to_s
categories_hash.each do |key, value|
if key != “id”
category = Category.find(value[:id].to_i)
category.show_order = key
category.parent_id = parent_id
category.save
i_sort(value)
end
end
end

Suerte.
