similar to: counter_cache is not looking for children_count with acts_as_tree

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 =

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

As far as I can tell, the counter_cache option on a belongs_to model doesn''t actually save anything in the database. For example, I have the following models: class Parent < ActiveRecord::Base has_many :children, :conditions => "deleted_at IS NULL" end class Child < ActiveRecord::Base belongs_to :parent, :counter_cache => true end With the following

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

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: StatementInvalid in PagesController#create --------------------------------------------------------------------------------------

What are the limitations on using: errors.add_to_base to display errors in views? I have tried for days to add errors from my object.rb and they never get displayed. class Keyword < ActiveRecord::Base validates_presence_of(:name, :message => "Name is required.") validates_uniqueness_of(:name, :message => "This name is already in use. Please try

I am a bit confused about counter_cache here. The API docs http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html say that only the belongs_to association can take the :counter_cache option. When I try to use it on a has_many I get an "unknown key(s): counter_cache" error. Why would this be the case? belongs_to means that this model has a field with an id

I have a model that I''ve been indexing and searching with ferret with no problems. I just added a counter_cache for some voting functionality to the same model and now when I perform the voting fxn on an object from that model, I get the FileNotFound error as it looks for a file named "_1c_1.del" ...which breaks my voting function. I tried killing the server and my index

Hi, I have the following code: Message, belongs_to :topic, :counter_cache => true topic = Topic.find_from_permalink(params[:id]) topic.messages.create(params[:message]) When the message gets created, then AR issues a supplemental SELECT to retrieve the message''s topic and then updates its messages_count. Why is that happening? If I do it manually: if

I''m trying to use counter_cache, but I''m not doing something right. It is unreliable and I keep having to correct it manually. Is there a good tutorial or reference on how to use it on-line? I have the AWDR book, but I need something more complete. TIA, Jeffrey

Hello world... I have an interesting issue that the online docs aren''t helping me with. In my app I have 4 models Item < ActiveRecord Deal < Item Product < Item Category < ActiveRecord Item has_and_belongs_to_many :categories... On each category record I''d like to maintain a product_count and deal_count to increase performance. This doesn''t appear

Hi All, I''m using a counter_cache, which I believe I''m doing correctly because I can see this SQL query being executed in the development.log file: UPDATE gifts SET bookmarks_count = bookmarks_count + 1 WHERE (id = 276) However, in the gifts table, the bookmarks_count field isn''t incremented (it''s zero). If I literally copy and paste that query into the

Has anyone extended Rails''s acts_as_tree to use the Modified Preorder Traversal algorithm? This is a really clever trick for optimizing access to trees stored in databases, as described lucidly in this article: http://www.sitepoint.com/article/hierarchical-data-database/2 It adds two integer fields, a "left counter" and "right counter", to each row. By

I want to implement a unique category tree per user in my system, and I was hoping to use "acts_as_tree" on my category model. It seems as if acts_as_tree makes the assumption that the entire table the model is off of is one large tree. I actually want each user to have their own category trees all stored in the category table so I need it to scope off of the user_id.

Hi There! I''d like some feedback before I try to implement some funky rails routes based on an acts_as_tree model. I have a Page model that acts_as_tree. I''d like the URLs to look something like this: http://localhost/about-us/staff/jeff or, another example... http://localhost/what-we-do/products/our-great-cms/features/faqs/ So, as many sub-nodes the user creates,

So I have the following model class Topic < ActiveRecord::Base belongs_to :topic has_many :topics, :order => :position acts_as_tree :order => :position acts_as_list :scope => :topic_id end that I use for a site''s navigation. Everything (list, create, edit, even the drag&drop sort) works fine, except the destroy function, which the vanilla version def destroy

I am creating forum application which needs usage of acts_as_list or acts_as_tree or acts_as_nested_set. I am unable to decide among these. please could some one recommend from their experience? -- Posted via http://www.ruby-forum.com/.

Hi, I''m trying to implement a very simple acts_as_tree search in my index html. I am able to show the parents, with no issue, but the children will not show. I have something like this for the parent, which displays fine: <% for group in Group.roots %> <td> <tr> <a href="#" onclick="Effect.BlindDown(''show_<%=

Using acts_as_tree, is it possible to get information of the depth a tree leaf in relation to the root? Or is available to derive information to save in the way "position" can be derived and saved for acts_as_list. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I am struggling with how to do eager loading of an acts_as_tree model. If the model Stuff acts_as_tree I know I can do this to get children as well: Stuff.find(:all, :include => :children) But what if the model I am including is the one that acts_as_tree? For example, say Picture belongs_to Category. Category acts_as_tree and I want to get all pictures that are members of a category that
