I am using RoR ActiveRecord polymorphic inheritance and was wondering if it''s possible to access the base class'' association methods in the invocation of either to_xml or to_json without having to depict the base class data in the serialized string. Here are my classes: # base class class Asset < ActiveRecord::Base belongs_to :resource, :polymorphic => true

I just discovered James Golick''s resource_controller plugin http://jamesgolick.com/resource_controller after spending another stretch of boredom making the changes to nest yet another rails resource controller. I''d actually slowed down this time to think about what I was doing in hopes of automating the task. I''ve tended to use script/generate rspec_scaffold to get

I am working on a small model mixin called attachment_kung to make attachment_fu polymorphic, so you no longer need a different table and Model class for every associated attachment (Productimage, Ad_doc, etc). All you really need is one model and table to handel all your attachments - in some cases, anyway. I have the code working, but have run into one small hitch that I can''t seem to

I am unable to call a polymorphic scope using the searchlogic plugin as it keeps on returning ''undefined method''. I am certain it is only a problem within my project as I created a test project and I was able to call a polymorphic scope using the searchlogic plugin. I am hoping someone can provide a suggestion on how to debug this issue. My project consists of several gems, and

Hello all, with great difficulty , I guess I have finally been able to find the appropriate git commit of paperclip which would suit my project''s config which is Ruby 1.8.7 and rails 2.0.2. I am trying to implement a POC before I integrate paperclip in my project. The POC is basically implementing each post with an appropriate image beside it. It seems to pretty much work, its just

Following is the model: --------------------------------- class Modul < ActiveRecord::Base belongs_to :modulable, :polymorphic => true end class Chapter < ActiveRecord::Base

Josh Susser tells in his blog that the opposite direction of polymorphic will get into trouble together with has_many through. This is the url: http://blog.hasmanythrough.com/articles/2006/04/03/polymorphic-through I do that according to Josh Susser''s procedure: class Tagging < ActiveRecord::Base belongs_to :tag belongs_to :taggable, :polymorphic => true belongs_to

I would like to associate a ‘product’ model with 3 models inherited from ‘image’: part, action and accessory. I have it working with Has_many :through relating products to images through attachments, I then have to determine the ‘type’ of the STI extension. This means i have to go product.images. While this is ok, i can see it getting tricky when i want to go products.images <<

My app has an association that''s got me scratching my head. I have Users, and Images. A User has many Images. (Yes, another picture sharing app, but it''s for a small niche, and it doesn''t end in -r!) I would like to express a "Favorite" relationship between both Users to Users, and Users to Images. This seems like the opposite of the standard

i''m trying to get :through associations working per the wiki: http://wiki.rubyonrails.com/rails/pages/ThroughAssociations i follow the instruction to the t, with the exception that i''m trying to use it with a polymorphic association. here are the associations in my models: Collection has_many :collectings Collection has_many :collectables, :through => collectings Collecting

I am creating a database for movies (films) and television shows (shows) that will have has_and_belongs_to_many relationships with the pictures table. CREATE TABLE screenshots ( id serial NOT NULL, filename character varying NOT NULL, content_type character varying NOT NULL, primary key (id) ); CREATE TABLE films ( id serial NOT NULL, name character varying NOT NULL,

Hello all, I''m having a strange issue with a model that belongs_to two other models. The one association is polymorphic and the other is normal. ================================ class Role < ActiveRecord::Base belongs_to :user belongs_to :permission, :polymorphic => true end class User < ActiveRecord::Base has_many :roles has_many :programs, :through => :roles end

Hello All, I have a little challenge and I am not sure if this is even possible I am working on a dating/event site and few functionalities are similar that I want to centralize them. We have users which can have - favorite users - interest list - blocked users All these relations are like; User <-> Relation <-> User I was thinking I could have a class called Relation (with a

Hi, seem to keep running into a wall here. I can''t find any resources on site navigation that can deal with any model being in the nav, allow nesting, and can dynamically update. So I thought about it for a while, and decided on a MenuItems class, which contained the position of the child in relation to it''s siblings, where the parent and the child were polymorphic. Then a given

Hi everyone. Ive part of a project that I need to refactor, and im having some difficultly deciding which path to take. Perhaps someone can help, I think its primarily a design question. A Spec consists of many Nests and many Parts. Nests contain Parts. Here''s what I have, which works well currently: --------------------------------------------------- class Spec <<

As great as Rails 2.1 is, I for the life of me cannot figure out why polymorphic associations do not support reconfiguring the type column used. For example, I have no way to do a polymorphic association using a lookup hash which maps an integer to a class name. Storing a TINYINT unsigned is waaaaay more efficient than storing a string like "SomeActiveRecordModel" over and over again.

Hi Guys, I am writing a plugin that has a "has_many" relationships via a join_table. It is polymorphic so I need to filter the class name. How can I get the extending class''s name in the plugin in? e.g. has_many :contents_states, :conditions => {"content_type =#{self.class.name} } Thanks!

Hi, I''m currently having the situation where I have to implement a polymorphic has_and_belongs_to_many by introducing an in between model that handles all the "has_many :as" and "belongs_to :polymorphic" association implementations... and is not doing anything else. Thing I don''t like it here is, I am unnecessarily loading AR instances only to execute SQL

Hi all. I''m having a problem naming a polymorphic relationship. Here''s my thinking... First, an analogy. You''re walking through the mall. Through a window you see a game you''re interested. I''m attempting to model the relationship between your interest and the game you''re interested in. I have an InterestList. It''s job is to maintain
