I am developing a CMS using act_as_tree for the pages and act_as _list to order them (as shown on Railscasts). Each page can load a custom ERB template, for instance I have one to display a standard article and one to display a group of articles (so acting as a category of underling articles). If I want to develop a forum, let''...

Hello I am using a data structure that resembles a tree with ordered items. I know I can use :order in act_as_tree to sort the items at each level, but since the items have no logical order I would have to use a table column just to store this order. My experience with position indices of this kind is that it can lead to inconsistencies in the database so I am reluctant to use such a solution. So my questi...

Two models: class Project << ActiveRecord::Base has_many :files end class File << ActiveRecord::Base has_one :project acts_as_tree end Inside of the project model, when creating a new product, I want to store the hierarchy of files within it.

...d bookstores. Within that table are columns such as bookstore name, city, state, and zip code. What I''d like to do is display the City and then every store name for that city underneath it. i.e. City - Store 1 - Store 15 Another City - Store 2 - Store 5 etc. I''ve seen act_as_tree but I don''t know if it''ll help me as I''m just using one table here. Is there a rails way to do what I want? Thanks! -- Posted via http://www.ruby-forum.com/.

Hi all, I have a large set of data to load, many of which are part of a big act_as_tree model. Right now, I am testing the creation with migration for the first layer of the tree but for the second layer, I have to know the ID of the parent_ID. So far, it is easy because I can guess it by looking at the insertion order, but I was wondering if there are any better way to do this.....

...- in fact I only picked up the books a couple of days ago and already I''m thinking of porting some of my apps across! At present I''m working on a relatively simple application that does online testing for schools and colleges. The school can create a hierarchy using the "act_as_tree" functionality in Rails. They can also create "Exams" and "Students". These can be "linked" to any part of the tree, the idea being that an Exam is visible to any students at the same level or below it in the tree and that Students can only see exams that are...

Hi all, I''m having two tables: contacts (belongs_to) company details. The problem is this. In the company table I have a field "pid" (parent id). Which relates a company (being a possible subsidiary) to it''s parent e.g. a bigger enterprise. Does the belongs_to work when related to the same model (table). The relation is upwards only for now. I don''t want

Hi, Just upgraded to Rails 0.12.0 and ActionWebService 0.7. I''m using the special struct class to create custom structs. In version 0.6.2 I was able to receive nil values for members of the struct. As of version 0.7 all nil values seem to be rewritten to some default value (empty string for string member, 0 for int etc.), which breaks my application. Is this a bug or a feature?

...he correct command (I already deployed several rails apps successfully before). I checked that the database is created with the correct tables. I ran script/generate scaffold and got all the files correctly created. Why is it not working? Could it be a problem of rails version? I am trying out act_as_tree in the model definition.

I''m using acts_as_tree to maintain a hierarchy of categories (each top-level category can contain multiple categories and each sub-category can contain multiple sub-categories, etc.). I want to be able to find all parents of a particular category. I realize that I can use @category.parent or even @category.parent.parent to move up in the hierarchy, but I need this to happen dynamically

I need to make a category browser that would allow nested categories. Is there any receipe on that? Currently, I use the :onchange event from one of the form element to update the first select (out of 4-5 selects), but I dont know how to elegantly reset all the child selects if I change the value from the first. All the categories are fetched from the DB and I would like a
