search for: base_classes

I have a couple models that inherit from a base class that then inherits from AR. When they are used in a polymorphic relationship the "type" is always the base class. Just curious if anyone has a reason why it doesn''t use the *actual* class rather then the base_class. I have patched AR to use the actual class if !base_class.table_exists? but it adds another query each time

Hi All, Rails newbie here trying to set up acts_as_versioned according to Chapter 14 in the Rails Recipies book. I''ve taken the following steps (nearly verbatim) as mentioned by the book: - created the target model "Post" - added the "acts_as_versioned" label to the model file - generated a migration file - added the table creation code and the command

Running into an interesting problem that at first glance appears to be a bug in the AR association code. However, it''s explicitly coded this way so I''m not so sure. I have some code like this: class Address < ActiveRecord::Base belongs_to :addressable, :polymorphic => true end class Person < ActiveRecord::Base has_many :addresses, :as => :addressable,

Hi all I have the following plugin code: module IncenseCrud def self.included(base_class) base_class.extend(ClassMethods) end module ClassMethods def performs_incense_crud def index list return render(:action => ''list'') end end end end In init.rb I have the following: require File.dirname(__FILE__) +

It looks like cached-model is broken again under rails 1.1. Can anyone confirm? Note that the exception below indicates it''s trying to treat CachedModel as the class name of the model, rather than using the proper class name (which is Entry in this case, and the table called entries). This is a model using Single Table Inheritance and acts_as_tree, and worked just fine under 1.0 and

Hi, I have an application that uses single table inheritance. Very simple stuff: class Place < ActiveRecord::Base class City < Place lets say I have a City on the @place whenever I try using the render @place I will get an error, saying the templace cities/city doesn''t exist but I do have a places/place template. Is the any nice way to add this fallback for the base_class

Hey .. The QueryParser RDoc page explains to me on how to search for a specific value in a specific field. This is not working the way i thought it should be, what am i doing wrong? Here''s an example .. I''m storing model data in the index like this: doc << Field.new( "object_id", object.id, Field::Store::YES) doc << Field.new( "type",

I''m trying to implement acts_as_rateable to my Beast installation to give users the option to rate posts (like reddit). I chose acts_as_rateable as it supposedly easily allows reddit-type voting but I''m having some problems setting it up and the documentation seems outdated. (http://www.juixe.com/techknow/index.php/2006/07/05/acts-as-rateable-plugin/) So far, I''ve

Hello, I have set up that uses single table inheritance. I have a number of model subclasses following the example in AWDWR that uses Manager < Employee < Person. First question. Do I need to create controller classes for each? I don''t think I do because a single controller should be able to shunt the data between the models and the views. Second question. Say I have a view

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

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.

I love the query interface (ActiveMethod::QueryMethods), but one thing has bugged me: why doesn''t it generate calls for polymorphic associations? For example: class MyModel < ActiveRecord::Base belongs_to :parent, :polymorphic => true end I would expect: MyModel.where(:parent => a) to be equivalent to: MyModel.where("my_models.parent_id = ? AND

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde
