Hi folks, I''m trying to migrate a less-than-ideal schema for a Rails app that helps role-playing gamers (the pencil-and-paper type) connect with each other, at http://findplay.anvilwerks.com (the source is available there too, for the curious). The schema currently uses columns for played_games, wanted_games, and favorite_games in the players table; each of these holds a foreign key 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 <<

Here''s the setup (working off Rails 1.1.4): Class Project belongs_to :employee Class Employee < Person has_many :projects When I try to paginate(:employees, :include => :projects) I get the error "Association named ''projects'' was not found; perhaps you misspelled it?" I can :include other models that the Person class has_many or habtm of, and if I

I''m considering serializing attributes of extended classes to one column instead of using STI. Each of the extended classes will have associated views to render the UI based on the serialized params. The references to the associated views will be stored in the model. I don''t need to query the params. I''d like to hear about any pitfalls and experiences of others who may

I''ve written an extension to AR to allow hiding of attributes(aka columns) in AR objects. If there''s interest in it I''ll roll it up into a plugin. Here''s an example: (straight from Agile Web Dev) # The table create table people ( id int not null auto_increment, type varchar(20) not null, /* common attributes */ name varchar(100) not null, email

Hi, It seems that setting a with_scope on the parent class doesn''t do anything MyClass.with_scope(:find=>{:conditions=> ["somecol = ?", ''val'']}) do @ext_pages, @ext_rows = paginate :my_extended_class, { :per_page => 13 } end # this doesn''t generate WHERE somecol=''val'' In order for scope to work you have to call

I''m trying to understand how to do the following, but am finding myself stuck. I have three main tables; here are the first two: CREATE TABLE reference_items ( "id" integer primary key, "type" varchar(20), "title" varchar(255), "year" year(4) ); CREATE TABLE "agents" ( "id" integer primary key, "type"

Hi all, I need to model simple typed polymorphic relations: ''John'' [''works_for''] ''Bill'' ''John'' [''speaks_for''] ''Microsoft'' ''Microsoft'' [''hold_shares_of''] ''Apple'' I''m having a hard time combining : - S.T.I.

OK. Here''s another one on STI (thanks for the help of all of you with my previous STI question, and I promise to update the wiki with the info). I''m having a prob with validation with the sub-classes. It''s a bit long-winded to explain, but I''ll post all the logs and code if there''s no obvious answers. Basically, however, I have validation on the

Hi, This does not seem to be covered anywhere. Since base class extends ActiveRecord with a table that has fields for all heirs, would that mean that any heir class can access any of those attributes, including ones that belong to other heirs? Or I am missing something? -- Posted via http://www.ruby-forum.com/.

http://kylemaxwell.com/articles/2006/02/06/fun-with-single-table-inheritance I wrote an article about how to use rails and single table inheritance to implement multi-page web forms with incremental validation. I''m looking for any feedback, and I hope that the development technique is useful. I just ran through the tutorial myself, and everything is working for me on my

Hello ~ I have run into an issue with some of my objects not behaving as I expect. Basically I am using STI on my Users table and have several types of users. BaseUser --UserType1 < BaseUser --UserType2 < BaseUser etc.... Recently when I create a UserType object and save it to the database it ignores the validation rules for the parent class BaseUser. Furthermore the after_validation

Folks, I''m fairly new to Rails, and I''ve Googled around for an answer to this question with no luck... Consider a little blog application that has uses single-table inheritance for the handful of different content types via a Content base class and subclasses like FooContent and BarContent. That part all works well for me. Now consider the view that presents actions to the

I suspect this is a bug. Or a limitation. Problem: ---------------- When you include a STI class in a ''find'' : @results = Result.find :all, :include => :event , you are forced to specify the fk and the class name : belongs_to :event , :class_name => "Event", :foreign_key => "event_id" . Full code: ----------- class Event <

Is there any way to get AR to instantiate a different class when using STI? Where it would normally instantiate Digit, I would like it to instantiate SkelDigit. Here''s why... My rails app has the following STI hierarchy: Digit < Glyph < ActiveRecord::Base My migrate script can''t use those classes directly however (backward compatibility issues), so I created some

If I define an association (in my case a polymorphic one) in an STI parent class, and try to eagerly load it in a subclass, I get the following error: ActiveRecord::ConfigurationError: Association name ''myassoc'' was not found; perhaps you misspelled it? If I redefine the same association again in the STI subclass, it works. Is this a bug or what? -- You received this message

Check it out y''all: http://rafb.net/p/NJg5U147.html (pastie was down) I''m trying to make a tree which belongs_to another model, where you can have sections or items as children, and sections can have sections or items as well. Moreover, any siblings should be sortable. For instance: Root - Section 1 - - Item A - - Item B - Item C - Section 2 - - Item D - - Section 3 - - - Item
