Using set_primary_key breaks acts_as_tree with non-integer column
I just switched from using the standard "id" column into using my own
primary key and generating my own unique id for each record. But, this
breaks acts_as_tree.
Because my new primary key is not an integer, it breaks the SQL query
as follows:

acts_as_tree & acts_as_list for a single model?
Hi,
If I have a db table
categories
- id
- name
- parent_id
- position
is it alright to have the Category model act_as_tree and for each
level act_as_list?
class Category < ActiveRecord::Base
acts_as_tree :order => :position
acts_as_list :scope => :parent_id
end
Thanks,
Peter

counter_cache is not looking for children_count with acts_as_tree
Hi there, the acts_as_tree API says that I can set a counter cache and
that it will automatically increment the "children_count" column. I
did that but when I create a new page it asks for a "pages_count"
column instead.
Here is the relevant part of page.rb model:
class Page < ActiveRecord::Base

acts_as_tree with acts_as_list
Hello all,
I''m having trouble using acts_as_list with acts_as_tree
to order the "children". I''ve found a few old posts on the web
that seem to indicate that this once worked.
class Whatever < ActiveRecord::Base

Although the ''position'' field is being populated,

Managing Hierarchical Data
Hello,
I am in the process of trying to date hierarchical data in a MySQL
database and convert it into a treeview view JS scripting. As a beginner
to ROR there are still many unknown things to me, and handling this sort
of data is one of them. My question is this: Is there any built in

acts_as_list with 2 fields in the scope
Hi Railers,
I''ve got a Categories table.
I want it to act as a list within the scope of the parent_id AND the
site_id.
Categories table :

So, in my Category class, I have :
acts_as_list :scope => ''site_id = #{site_id} AND parent_id = #
{parent_id}''
The problem is that when I try to move_up a Category with a parent_id

Drag and Drop Sortable Tree
I''ve gone through Chad Fowler''s recipe for creating a drag and drop sortable
list, and have been trying to extend this to a sortable tree. Has anyone
come up with or seen code which allows drag and drop sorting (altering the
position and parent_id variables of the relevant objects) but for data in a
nested tree rather than a list form?

Associated child records not created on creation of a parent.
I am trying to create a record with association. Within the create
method, I would also like to pre-populate dependent (has_many) records
from a template in the database.
The child records are <u>mysteriously rolled back </u> if I insert
them in a loop. If I try to insert a single child record, it works.I

Many-To-Many w/acts_as_tree?
Guys,
I''m having a problem getting acts_as_tree working. It seems from the
Agile book (p. 255) that acts_as_tree only supports one-to-one record
relations, whereas I need many-to-many support. In other words, looking
at the picture at the top of page 256 where where only 1 id is linked to
1 parent_id, I need multiple id''s linked to multiple parent_id''s - for

Many to Many Category structure with itself
Basically, I''m trying to have a table called "categories" have a many to
many relationship with itself. But I also want each catagory to be able
to be "copied" into another category so it is essentially a child
category to more than one parent. To me the obvious way of doing this is
by creating another table called category_maps (and a model called
CategoryMap).

acts_as_family_tree
For a project that I am working on I need to have a family tree. This
means that instead of having one parent each item has at most two. As
far as I know acts_as_tree only allows one parent_id. Any suggestions
on how to make a "acts_as_family_tree" ?
Thanks,

Active Record acts_as_tree and leaf depth
Using acts_as_tree, is it possible to get information of the depth a

information to save in the way "position" can be derived and saved for
