I''ve got quite the ActiveRecord challenge, any help would be appreciated. In my current project Companies can have many reviews. class Company < ActiveRecord::Base has_many :reviews, :as => :reviewable end However, my company table, I have two different IDs to identify my company. id - This is the typical id we use for normal stuff other_company_id - This is the id we use

With the help of several heroes here yesterday I beat my way into a working solution to adding comments to one or more models in my application using acts_as_comentable. Great plugin, but my implementation is lame. I need enlightenment. I have users who log in. For several views I want to let them add comments. Enter act_as_commentable which does just this -- it''s polymorphic, so you

I''m trying to map Rails to an existing schema, and having a bit of a time of it. I''ve got a table Content, and I''ve got a table Review, which is a type of content. So content has an ''id'' field, and Review has a ''contentid'' field. Not all Content has a Review, but all Reviews have exactly one Content. How do I represent this?

I''ve read AWDR and especially the part concerning adding child line_items to an order. Unfortunately I want to do my process in reverse and in doing what I thought would work I get a null object error when trying to append the children to the parent. This is a _major_ stumbling block in my Rails use as almost every one of my projects has needed this so its a pretty vital problem I need

Hello, I am trying to use XML package to download Facebook reviews in the following way: require(XML) mydata.vectors <- character(0) Qword <- URLencode('#IBM') QUERY <- paste('SELECT review_id, message, rating from review where message LIKE %',Qword,'%',sep='') Facebook_url = paste('https://api.facebook.com/method/fql.query?query=

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

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

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

Consider the following: class Event belongs_to :event_object, :polymorphic => true end class Asset < ActiveRecord::Base end class EventedAsset < Asset has_one :event, :as => :event_object end EventedAsset.find(:first).event generates the following SQL: SELECT * FROM `events` WHERE (events.event_object_id = 1 AND events.event_object_type = ''Asset'') LIMIT 1

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, 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

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

Could someone please help me with this association scheme? I am familiar with habtm as well as the :through association but this one has me stumped. Here is an example DB.

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,
