similar to: [RFC] Nested Restful Resources + Polymorphic Associations

I have just updated rails and added polymorphic associations but they are not working properly. I''m following the recipe 17 of "Rails Recipes" and I''m getting an "Unknown key(s): as" error. These associations work properly on the console. The problem occurs when I''m listing the items... perhaps the problem is pagination. Is this a bug or what

If anybody on edge familiar with this could help, that would be "great" :) I have different types of things I want to be "reviewable". So, instead of having a slew of HABTM... this new Polymorphic Associations schtick seemed like the best solution. I have everything setup as I thought it should be (so I think)... but it doesn''t appear to be working correctly. Here

Hi people, I''m looking into polymorphic associations as a way to cleanup some messy parts of my code. I think they will allow me to do exectly what I need, but since there''s little to none written on this subject, I''d be delighted if someone could shed some light on this. Especially what the different options and needed table structures need to be. Thanks, -

Hey guys, I''ve been thinking lately about polymorphic associations, and I wonder: is there a noticeable or tangible performance "hit" from doing polymorphic associations when you''ve got your database under really high query load? So for example, maybe I have a "message" model, a "user" model and an "administrator" model, without any

Hi everyone. I''ve made a default change to has_many :through associations that I felt was important to make before they''re released. This is after some tickets and confusion I''ve seen regarding has_many :through. class Connection < ActiveRecord::Base belongs_to :user belongs_to :channel end class Channel < ActiveRecord::Base has_many :connections

Hey, I am starting my store application again for the 3rd time, I am just trying to get eveything right so that I don''t come up with any more complex problems later. Hopefully someone can steer me in the right direction. I have a store that sells lots of types of product. e.g. CDs, T-Shirts, DVD Each product type has different associations. Cds - multiple artists, multiple genres,

Recently, I converted a single table inheritance design over to polymorphic associations as that made a lot more sense from a database perspective. One of the features of the ui, a drag and dropable list of items, needs to be completely reworked though. Instead of having one table with a "sort" column, I have 1 polymorphic table "items" acting as a pointer to 3 or 4 other

With ref to my previous post: http://www.ruby-forum.com/topic/180356 I am now able to access items from topics controller. However, now I need to add sub-item e.g.: An item itself could have many sub-items. So my items model is like: class Item < ActiveRecord::Base validates_uniqueness_of :title, :scope => [:topic_id] validates_presence_of :topic_id, :title, :owner, :position

Hi. I have a couple of best practices questions regarding polymorphic associations, naming join tables and user permissions. Currently I have implemented the user authentication model from the rails recipes book. Basically it goes something like this: MODEL CLASSES: class User < ActiveRecord::Base has_and_belongs_to_many :roles end class Role < ActiveRecord::Base

Is there any sort of dynamic finder for polymorphic associations? For example if I had: class InviteNode < ActiveRecord::Base belongs_to :inviteable, :polymorphic => true end I would like to be able to search by: InviteNode.find_by_inviteable(some_object) instead of having to do: InviteNode.find_by_inviteable_id_and_inviteable_type(some_object.id, some_object.class.name) obviously I

Hi, I''m just playing with ActiveResource and I did''nt find anything about the support of (polymorphic) associations. Is there a support at all?

hi folks: I follow this article:http://clarkware.com/cgi/blosxom/2007/02/24 all goes well except the public_filename ，it return something like "photos/0000/0001/test.jpg" ,not the expected RESTFUL URL LIKE ''photos/1/test.jpg'',any suggestion? My Env is Rails 1.2.3 on Ruby 1.8.6 with attachment_fu from http ://svn.techno-weenie.net/projects/plugins/attachment_fu/ by now

Polymorphic associations work great until I try to do some eager loading through :include. In my example, the interface name is ":imagehaver". Here''s my little eagerly loading find line: Image.find(params[:id], :include => :imagehaver) All it gives me is an ActiveRecord::EagerLoadPolymorphicError with no further explanation. I haven''t been able to dig up anything

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

There is a dedicated section about eager loading in the docs. A coworker discovered eager loading does not work in polymorphic associations the hard way :-) so I''ve written a patch that documents it: http://dev.rubyonrails.org/ticket/10610 There are at least a couple of tickets that implement something that would change that though: http://dev.rubyonrails.org/ticket/9640

I have a MasterEvent model. It has attributes that is required by another model Event. The user selects the MasterEvent model and I create the Event model by merging the attributes of the selected MasterEvent with the attributes that were presented for the Event model in the form. I have association declarations in the MasterEvent and Event models. If I use STI does the subclasses inherit the

Hello, I''m trying to solve a problem without success. Look at: I have 3 models (Recipe, Comments and User) an Recipe has many Comments an User has many Comments an User has many Recipes I tried to implement this using polymorphic associations with the Comment model. But the expected behavior needs to be: When a new comment is created i need to refer it in Recipe and Comments. To

Hi friends, i''m usgin the edge version because i need eager loading on polymorphic associations support, but i see this: Message.find(:first, :include => :owner) #This generate this query: SQL (0.000072) SET SQL_AUTO_IS_NULL=0 Message Load (0.000389) SELECT * FROM `messages` User Load (0.001070) SELECT * FROM `users` WHERE (users.id IN (1,2)) And this Message.find(:first,

Hi, I''m searching for a method of eager loading polymorphic associations under activerecord 2.0.2. After some initial google-fu I came up with a link to an enhancement that''s been added to edge: http://dev.rubyonrails.org/ticket/8119 Anyone have any idea how long that might take to work its way into a general release? I''m early in development now so I can afford to
