similar to: list of methods derived from associations?

I''m sure this is really obvious but I''m feeling my way here with rails (and Ruby) and have tried a couple of things without success. So, can anyone tell me the best way to reverse order the retuen list of ancestors. In the controller I have: @ancestors = @category.ancestors which returns an array starting at the parent and ending with the root. When I then loop through the

Hi, I''m using the new(?) as_json methods within a rest api I am working on. However I am not sure how you are supposed to, or whether it is designed to handle multiple variations of association inclusion. For example I have a model using acts_as_tree, so that each instance has children and a parent: class CatalogueCategory < ActiveRecord::Base acts_as_tree JSON_ATTRS =

Hi folks, For my app, I needed to modify acts_as_tree (ActiveRecord::Acts::Tree) such that deleting a node would orphan sub-nodes, rather than deleting them. This is accomplished simply by allowing a :dependent option to the acts_as_tree method so that it can be set to :nullify. For my app, I simply did this by adding a file tree.rb to my lib directory and requiring it in the model. A number

Hello people on rails, I am developing a web interface for a database that has hierarchical data. I want the user to be able to browse the tree (~1300 nodes) and activate/deactivate and showing/hiding groups of nodes (like selecting one node selects all the children and the leafs). So I have a tree of objects (ActiveRecord acts_as_tree). Because I need the tree to be persistent and I

hi, im using acts_as_tree and im not sure on how to group find-result. x = find.almost_all <p> <% for y in @x.ancestors.reverse %> <%= link_to h(y.title), page %> &gt; <% end %> </p> gives me a nice "breadcrum". but how is it possible to group the list lets say by the 1level or second level? thx -- You received this message because you are

For a project that I am working on I need to have a family tree. This means that instead of having one parent each item has at most two. As far as I know acts_as_tree only allows one parent_id. Any suggestions on how to make a "acts_as_family_tree" ? Thanks, Mark -- -------------------------------------------------------------------- I am Mark Daggett and I approve this message.

I''ve got an acts_as_tree structure which I want to be able to represent in the URL, with one field identified as the url component. In other words, if I''ve got this: def self.up create_table :nodes do |t| t.column :parent_id, :integer t.column :tag, :string end end and class Node < ActiveRecord::Base acts_as_tree end and what I want the urls to be is something

Hi, I''m using the latest gem version of rails under MacOS Tiger. I was trying to use acts_as_tree as described in the rails book. So I have something like: class Category < ActiveRecord::Base acts_as_tree :order => "title" end create table categories ( id int not null auto_increment, title

>From looking at the RSpec Rails documentation (https://www.relishapp.com/rspec/rspec-rails/docs/view-specs/view-spec) it seems like rendered is just a string and you can''t really do any assert_select type stuff out of the box. After Googling around, it seems that the RSpec authors decided that if you want that functionality, you should just use Capybara or some such... is that

hi guys, Using breadcrumbs on rails (http://github.com/weppos/ breadcrumbs_on_rails), I have added a method, "set_breadcrumb" in my application controller. That will set up my home breadcrumb.

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,

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

Hello, I''m trying to create categories that have their own subcategories, and each subcategory may have its own subcategories, .. and so on. After some reading, I found out that the best way for creating such a thing is to use acts_as_tree, but I didn''t find any tutorial or article that explain this in a clear way. After a lot of work I was finally able to create categories and
