similar to: acts_as_nested_set and acts_as_threaded

Hi, has anyone successfully used the acts_as_threaded plugin with postgresql? I''m using rails 1.0 and ruby 1.8.4 on linux. Following the screencast on http://www.railtie.net/articles/2006/02/05/rails-acts_as_threaded-plugin , I got to where we''re ready to create our first post, having made the changes to controllers/posts_controller.rb, views/posts/_form.rhtml,

I''m currently using acts_as_tree to display threaded Comments on my forums-like site. It''s waaay too slow to display a page with 1,000 comments, as it''s issuing a TON of selects. I''m pretty sure I want to convert to the nested set model, using acts_as_nested_set or acts_as_threaded. This should give me the performance I''m looking for. The problem,

This plugin is related to the acts_as_nested_set functionality but differs in that it allows multiple roots to exist within your database. The other benefit, is that when adding a child, it doesn''t perform a full table update to rebuild the tree, each child insertion only affects the tree that it is placed in. It even comes with my first screencast to show how you can build an old

Where can I see the API acts_as_nested_set constructs? I''ve read its page in api.rubyonrails.com but I don''t see how to manage the tree from there. -- fxn

Hi, When I try to run a controller that connects to my project''s sqlite database, I get the following exception: SQLite3::CantOpenException in PostController#index could not open database config/database.yml correctly points to my database, like so: development: adapter: sqlite3 database: db/dev.db I''ve had Rails projects working with sqlite3 before (recently), but

Hi, I have trouble accessing the acts_as_threaded plugin at http://railtie.net looks like the site is down.

Hi, In my blog i display a post. I want to display a link tot he previous post if there is 1 and a link tot he next post if there is one. So i have in my controller def post @post = Post.find(params[:id]) @post_pages, @posts = paginate :posts, :per_page => 1 render(:layout => false) end And the following code in post.rhtml <% if @post_pages.current.next %> <%=

Does anyone have the magic sql to get pagination working with acts_as_threaded? Return like: 1 - parent 1.1 - response 1.1.1 - response to response 1.2 - response 2 - parent 2.1 - response etc... up to the first 20 or so. It seems easy to get from a parent to all children, but to say get the first 20 parents and children is really hard for me to get my head around. I can imagine getting

How do I add multiple conditions to a paginated list? I have: @post_pages, @posts = paginate(:posts, :per_page => 10, :conditions => [ ''(title) OR (body) LIKE ?'', ''%'' + params[:query] + ''%''], :order =>

Is there any known problem in inheriting a Controller from another controller (that is to say having an Admin::PostController < PostController, with PostController < ApplicationController)? It is something I haven''t seen done in tutorials or books, however in my opinion (and as far as I can see from my tests) it should work.

I''m having trouble finding then displaying all items in my "posts" table that match a certain search string. I have a from field: <%= start_form_tag :action=> "search" %> <div title="Search" id="searchform" class="form"> <h3>Search</h3> <%= error_messages_for ''post''

I moved from acts_as_tree to acts_as_nested_set because I need the all_children method. I''ve seen an alternative way to add this method to acts_as_tree here: http://www.chuckvose.com/articles/2006/05/24/recursive-children But I''d prefer to use the more efficient way of acts_as_nested_set (and not to have to revert to my old code). Anyway, here''s my issue: if I

Hello, I am using acts_as_nested_set. My problem is that the columns "lft" and "rgt" get the value 0 if I create a new entity. If I delete an entity I get negative values (-1, -2, -3) - but for all entities. Is there anything missing? Is there any example for "acts_as_nested_set" in the web? -- Posted via http://www.ruby-forum.com/.

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/.

Hello, I have a tree structure that needs to be converted into a nested set. A great deal of work has already been done on the tree items, so maintaining the integrity of the id''s is mandatory. However I need the ability to access entire branches of the tree, which is what Nested set does. Does anyone have any suggestions on how to efficiently transfer the tree to the nested set and

I''m trying to enhance acts_as_nested_set. Well actually I already have, but I''ve done a hack up job of it. I would like to contribute these enhancements back, but I need a little help. I''m a complete newbie to this stuff. The only thing I new before coming into this project was vanilla HTML. So over the course of two weeks I''ve picked up Ruby, Rails, MySQL,

I''m trying to create a paginated list that will take note of the "end_date" field in my table. This is what I have: @post_pages, @posts = paginate(:posts, :per_page => 10, :order_by => ''end_date'') in the controller. And for the view: <h1>Posts ending soon</h1> <ul><% for post in @posts do %> <strong>Post Title:

I have a model using acts_as_tree which is working fine. Being new to Ruby I''m don''t know what enumerator is best to use for traversing a tree by depth. I can write one, but before I do I wanted to know if there is there an enumerator for traversing trees available that the community recommends?

I''m interested in working on a message board application that uses ruby on rails. I''d like to see something end up similar to vBullieten, but with more of a 37signals type of less-is-more philosophy... mostly meaning less need for preferences and settings and configurations. I''ve checked rubyforge, and it looks like there are various forum apps uploaded there, some

I''ve pared my rjs experiment down to what seems a bare minimum. When I click on my link_to_remote, the rjs executes, returns the correct javascript to the browser, but it doesn''t update the div I''ve specified. What appears to be coming back from the controller is: Element.update("my_form", "hello, rjs"); I''m tearing my hair out.
