similar to: as_json and self-referential associations

Hi, Does anyone know how to include nested associations when overriding a model''s #as_json method? Below is my attempt to include direct and nested associations. NOTE: "office" is a direct association, "company" is nested association via "office". I''d like both included in the generated json output. def as_json(options={}) super(:include

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

Hello; I''m at this point essentially a Rails hobbiest: entranced, enthralled, immersed but not writing Rails apps commercially. I am sure my question has been asked and answered but I searched and couldn''t find it, so.... Is there somewhere a list of methods that become available via associations? I was doing a project with acts_as_tree and was struggling with a breadcrumb

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

Hi all - I am having some trouble figuring out how to model self-referential entities in Rails. I have a "group" model, which can have 0 or more "group" objects or 0 or more "user" objects. I tried creating a subgroup table that has a parent_group_id and a child_group_id as foreign keys but can''t figure out how to create the mapping in my ruby model

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

Hi I''m using Mongoid and Rails 3, and I want to serialize one of my mongoid documents to json for publishing via a controller, e.g. class ReportController < ApplicationController respond_to :json def show report = Report.where(:report_id => params[:id]).first respond_with report end end This works ok, but pushes out every attribute on the document

Hi, I''m looking to add tagging to an application, and I would like to allow self-referential tags, so that I can tag my tags. With the goal of generating a flexible tag hierarchy. After some googling it looks like acts_as_taggable is not the best piece of code, and I''m hoping to use the has_many_polymorphs plugin from http://github.com/fauna/has_many_polymorphs/tree/master.

Hi, I''m having a little trouble figuring out how to make a self- referential HABTM bi-directional. I have a Employee class. Each employee can have a couple of bosses, who are also employees. The employee class has the following HABTM: has_and_belongs_to_many :bosses, :class_name => "Employee", :join_table => "bosses_courses", :association_foreign_key =>

Hi listers, I''m trying to build an xml doc using Builder, but I''m having trouble getting it to draw a tree structure from a self-referential table. Here''s what I''m after: ========================== ---- object structure ---- node (name => root) - node (name => child 1) - node (name => child 2) - node (name => child 2.1) - node

ok, guys i have followed the self referential recipe from the book it works perfect but now i have some doubts, at the end the model are modified to force the user beign added as a friend that add too who are adding him so how i can make that the full relationship doesn?t be complete until the friend beign added approves it(talking in the implementation of the code of course)? by the way,

Relative newbie so would welcome comments re structure of a self-referential relationship I''ve got. It''s started off similar to the Person HABTM friends in the Rails recipes books (working fine), but I needed to turn the join table into a full-blown model as I wanted to add attributes to it. Few tricky bits dealing with the new :through structure and understanding how :scope

Guys, Anyone ever had this kind of problem with ActiveScaffold? Cheers, Sazima ------------------------------------------------------------------------------------------------ What steps will reproduce the problem? 1. Create self-referential HABTM application (like the common "user has friends" example) 2. Try to add more than 1 friend to a given user using ActiveScaffold. What is

All: I have been working on making a self-referential habtm relationship that uses a join model because I want to store info about the relationship. I have been using two sections from Chad Fowler''s "Rails Recipes" as a guide, "Self-referential Many-to-Many Relationships" and "Many to Many Relationships Where the Relationship Itself has Data". So far I have

Hey guys, I could use some advice on a special case of a function pointer as a formal argument. I would like the function pointer type to contain the actual signature of the function, i.e. not a pointer to var args function. This becomes an issue when I have a function which can take a pointer to itself as an argument... our terminology for this is "a recursive procedure". That is, of

Trying to model a bunch of users that have friends that are other users. clearly a job for has_and_belongs_to_many, but the trick is, they have ratings for their friends. I have gone through the Rails Recipes book, and it seems like I''m trying to combine the self-referential many-to-many recipe (12) and the many to many relationships where the relationship itself has data recipe (16).
