...the following schema, dumped from sqlite3: CREATE TABLE children ("id" INTEGER PRIMARY KEY NOT NULL NOT NULL, "name" varchar(255), "parent_id" integer, "deleted_at" datetime); CREATE TABLE parents ("id" INTEGER PRIMARY KEY NOT NULL NOT NULL, "children_count" integer DEFAULT 0, "name" varchar(255)); CREATE TABLE schema_info (version integer); CREATE UNIQUE INDEX children_id_index ON children (id); CREATE UNIQUE INDEX parents_id_index ON parents (id); I would expect the children_count column in each Parent to be populated with the number...

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 :order => :position, :counter_cache => true acts_as_list :scope => :parent_id end A...

i am making a category tree and i iterate over the category using my counter_cache however it would show a different number than what was actually being represetned in the tree. Here is an example cat.children = [cat2, cat3] puts cat.children.size 2 puts cat.children_count 2 cat4.parent_id = cat.id cat4.save puts cat.children.size 2 puts cat.children_count 2 however cat.children.count produces the correct number (3) what gives? Thanks, Mark -- ----------------------------------------...

Before I file a ticket, I''ll query ya''ll about this: The API docs for acts_as_tree''s counter_cache is to create a database column called "children_count" to hold the counter_cache. I have enabled this option in my model. While writing tests I wrote a test for creating children from the a parent: message = @forum_message["parent"].find child = message.children.create( "member_id" => 1, "forum_id" => 1...

...f 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

...to the database and ready to go. But a problem occurs when I try to call methods on it with BasicObject#send. I take a list of fields from a yaml file (user supplied) then attempt to update the fields with BasicObject#send. yaml file example - content: some content parent_id: 1 children_count: 0 etc. So my code ends up like this: model.send(''content'', ''some content'') And it blows up with an error: ArgumentError: wrong number of arguments (1 for 0) /home/zatz/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/activerecord-4.0.1 /lib/active_rec...
