similar to: access to 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,

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

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

I''m trying to record a list of start and end times, and they''re simply an hour and a minute. Looking at the API, there''s a select_time helper, but that just creates the tag. There''s a datetime_select helper which takes an object and method name, so it does all the magic...but I only want to worry about the hour and the minute. I''ve tried writing my

Hi Railers, Is the nested set model restricted to only one root? I''m working on a screencast building a threaded forum and nested set comes close but is lacking a few items for this project. First, all the documentation I can find restricts a nested_set to one root node, and a threaded forum would have many roots. Also, without a ton of fancy sql or an ungodly amount of db calls, it

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

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? Thank you, Jose -- Posted via http://www.ruby-forum.com/.

During development, I''d like to see my Rails app from a computer other than localhost on a Linux system and also want to change the default port#. I thought this would do it: Linux server: $ script/server -b 10.4.1.84 -p 5432 => Booting WEBrick... => Rails application started on http://10.4.1.84:5432 => Ctrl-C to shutdown; call with --help for options ...

What is the best way to set up a relationship between two tables where table-1 has a one-to-one relationship with table-2 but table-2 has a one-to-many relationship with table-1? For example, suppose there is an events application (seminars, forums, conferences, etc). Each event has only one address but since many events can occur at the same location throughout the year, a given address can

I''m trying to use acts_as_nested_set, as modifed by Bob Silva to add threaded functionality. I''m getting the following error: undefined method `display_threads'' for #<PostController:0x3ae9828> ... #{RAILS_ROOT}/app/controllers/post_controller.rb:18:in `list'' Line 18 in post_controller.rb shows: [post_controller.rb] def list display_threads @posts

Hi, I''m trying to use counter caching in a tree structure (in this case Bob Silva''s threaded list). This is the definition: class Folder < ActiveRecord::Base acts_as_threaded has_many :files end I would like each parent to have the total count of all the childrens member. So when inserting a new file I update the file_count following the parent_id through all the

I have a forum-type application. The Board model has many comments, the Comments model acts as a tree. So I have a board with multiple comments, some comments are parent comments and there are comments that belong to a parent comment, making up a thread. Like most forums, I want it so that threads are sorted based on the date of their last comment. But I have no idea how to specify this in

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,

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

Hi, Is there any trick to initializing the params hash via submit_to_remote()? I have a form with two submit methods - the regular, non-AJAX method, and the AJAX method. The regular method works like a champ. The submit_to_remote invokes the correct controller, but the params hash is empty except for the values for :action and :controller. I''d show my code, but it''s on

Hello all, There''s a great patch in trac that fixes a lof of issues with the date helpers. I''m afraid it hasn''t had any attention yet. http://dev.rubyonrails.org/ticket/3811 This fixes all the little date_helper problems, except one: When you choose an invalid date ActiveRecord throws an ActiveRecord::MultiparameterAssignmentErrors. This used to work in 1.0,

The application I''m developing allows people to create events in their local area; as part of this feature I want to display a list of, say, the five most recent events within 30 miles of a person''s location. I have a User model and a Profiles model which contains the user''s location (city, state, zip code) among other non-related personal information. So what I would

I''m trying to add a link to download a zip file. I created a controller method that makes the call to send_file: def getzip send_file ''file.zip'' end When I navigate to this link I get a MissingFile exception. The file definitely exists (and U triple-checked paths and spelling) and the permissions are 644. I tried moving it to the /public folder and updating the
