Parent listing children.
My database is set up as Categories > Things associated by category_id
and has_many and belongs_to.
How would I go about listing all the categories and under each Category
is it''s children? Is there an easy rails way to do this - preferably
without using acts as tree? Any help is appreciated - thanks!

acts_as_tree validation on parent.children.create
Validation does not appear to execute on a call to
"parent.children.create". Anyone know if this is intentional, or am I
doing something wacky?
Thanks.

How can I overwrite the parent.children.push(child) Method?
Hi all
I want to overwrite the push method (which is an alias of <<, the same
as concat) of collections, and there I want to test if :uniq is set to
true in the relationship. If so, the method should check if the passed
object is already related to the parent, or not (only then it will be
added).
But I just can''t find the original code of this method, so I could

ZFS children stepping on parent
I was doing some disaster recovery testing with ZFS, where I did a mass backup of a family of ZFS filesystems using snapshots, destroyed them, and then did a mass restore from the backups. The ZFS filesystems I was testing with had only one parent in the ZFS namespace; and the backup and restore went well until it came time to mount the restored ZFS filesystems.
Because I had destroyed

When saving parent fails, children will still be updated
Hi all,
When submitting a master/detail form I first want to handle the children
before saving the parent.
There are has_many and belongs_to relations between the parent and the
children, so I can edit the children using (psuedo-)code like:
child.destroy for deleting, child.update_attributes for updating and
@parent.children.push(child) for adding child-records.
I update the parent by using:

[PATCH] PVWin: Fix warnings
This patch cleans up some 80-odd warnings I was seeing when compiling
the xenpci driver, all completely trivial. It also replaces the use of
asm for calling cpuid with the __cpuid compiler intrinsic, and modifies
calling code accordingly.
I''m pretty sure my mailer going to mangle the inline patch (below) so
I''m attaching the pristine version. (will try to fix for next time)

How to check if a parent has children?
What is the new way to check if a parent has child items? In rails
1.2.6 I did this:
if @client.has_line_items?
Client being the parent and line_items the children.
Now that I have upgraded to rails 2.0.1 (on my way to current :-) ) I
am getting this message:
undefined method `has_line_items?'' for #<Client:0x7f3b093b01a0>
How should I format the query now?

I need your suggestions for the following. I am still learning RoR and

If I am displaying the list of students and wanted to get individual
