Hi. I was wondering if it''s possible to combine effects for individual elements with RJS templates. I notice that scriptaculous has support for a concept called effect queues (http://www.railsdevelopment.com/2006/01/15/effectqueue/). Is there anyway to use these queues from rjs?

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 am working on an Rails application that uses a pretty complex category structure through out the site. I have defined a table to house all the info and a FK to reference parents within the table CREATE TABLE categories ( id int(11) NOT NULL auto_increment, name varchar(50) NOT NULL, parent_id int(11) default NULL, constraint fk_category_id foreign key (category_id) references

Hello, I''m using the Awesome Nested Set plugin: https://github.com/collectiveidea/awesome_nested_set And in my model I do the following: acts_as_nested_set after_save :ensure_max_nestedset_level private def ensure_max_nestedset_level if self.level > 2 self.move_to_child_of(parent.parent) end end I do this to keep the levels from getting

Hi, I''m working with acts_as_tree to print an unordered list of items: Root -- Child ---- Child I''ve got this working, however I''d like to know if there is a more elegant fashion that I''m unaware of: #Takes a parent category and recursivley returns all children def find_all_subcategories(category) if category.children.size > 0

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

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 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,

Hi, I''m trying to get act_as_nested_set working, and I''m puzzled.

Alright, I got this table with lots of entries for menus. There''s several menus (with their own model since each menu got some special information). Now, I want to be able to specify the order of the menu entries inside the menu. acts_as_list seems to not quite do the trick since it does ordering "globally" on the whole model and acts_as_nested_set seems like overkill since

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 got the following error when trying to create the elibrary instance (rdb:21) @elibrary = Elibrary.new(params[:elibrary]) RuntimeError Exception: Declare either attr_protected or attr_accessible for Elibrary, but not both. params : "elibrary"=>{"title"=>"bingo three", "short_description"=>"something new",

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

Hey guys, This is the final list of the new maintainers of each plugin. We need two more things to do: First please the owners of the repos add the rest of the maintainers. Second I will add a note on each rails/plugin mentioning this repos updates. So from now on, if someone else is interested in helping/contributing please send a message to the appropriate repo owner. verification

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/.

I''m creating a hierarchical tag structure for my portfolio. I have a few top level tags. those could then have children, those children could then have children. Pretty standard so far. Often a child tag will be under more than one parent (i.e. a child might belong toone or more parents) and it wouldn''t necessarily have the same children under one parent as it would in another.

Dear List, Given that I am developing a rails 2.3.5 site, When it comes to storing threaded comments in a blog or forum, Then which plugin/gem should be considered "State of the Art"?

wondering if anyone tried this patch. (i havent, seeing as its 1228 lines long, 10 months old, and cant take serious a patch many orders larger than competing web frameworks) in many cases i want to keep about 10 things around, eg recent searches, new items (spanning multiple classes), referers, page views, without logging them for perpetuity. so i guess this isnt a normal queue, more like a

Hello, How would I go about updating 7000 or so rows of my database with unique values? (In other words, I''m not setting them all to NULL or incrementing or something... each row gets a new, special value.) But I can''t seem to get my rails app to do this in less than 7000 connections to the database! I''ve looked very hard (3 horus!), and can''t find anything
