Hi List,
I''m new to and hot on RoR.
And I have a question regarding acts_as_tree and counter_cache.
What methods actually update the counter_cache column?
I''ve only really started the app so i''ve just got it set up so
that I
can select the parent node (from a list of nodes that exclude all
descendants of the current node) with a radio buttoned list named and
valued to slip right in with the default update code (ie: using
update_attributes)...
However, it doesn''t update the counter_cache column.
After some experimentation I found that (as in the documentation
example) root.children.create updates root''s cache correctly, as does
destroying a node.
pushing into the children, while updating the parent_id correctly,
doesn''t update the count (as with update_attributes)...
Is there another method for rearranging the tree structure that would
be more appropriate?
I could update the counter_cache columns myself but I thought "then
why have a configuration option?"
Also, speaking about the documentation at
http://rails.rubyonrails.com/classes/ActiveRecord/Acts/Tree/ClassMethods.html#M000277
it wasn''t too clear (for me at least) that the counter_cache column
shouldn''t be named children_count, but rather classname_count
(refering to "counter_cache - keeps a count in a children_count column
if set to true (default: false).")
Thanks for the ear!
Earnestly,
Caleb
