STI versus Composition...or the headaches of one big table
Guys, I have a relationship between model classes that I believe is best represented by inheritance, but the likelihood that things will change often is driving us to composition instead. So, I have a class called Autos, and subclasses called Suvs, Minis, Mids, Sports, for example. We have been requested to avoid the STI approach to this, because of fear of a quickly growing table with

Re: STI and Joins Broken
I''ve made a inheritance rework some weeks ago that would possible fix it since it only loads the inheritance support in the class that''ll use it. In STI case, it would load only if the class that descends directly from AR has been inherited and the column specified in the inheritance_column is available. People here told me to wait until next release so we can dig into this, but

Change the value stored in inheritance_column
I have been struggling for quite sometime with this. Is there any way to configure the Model to store user defined value in the inheritance_column instead of the default value (which is class_name) The problem I have is like this: I have a User model and there are different models which inherit from this like Admin, Premium, Professional, etc. Each of these inherited models are identified by a

It seems it doesn''t index everything in my STI model, also if I do a search from my base STI class I get a result count but no results. If I run the same search from one of the children STI models I get the appropriate results (if the information

Model using STI new function only working partially
Hi, I have an application using STI on a model named Publisher. Publisher uses STI via a column named "service". When I call -- p = Publisher.new(..., :service => "TwitterPublisher") -- the service does not get assigned, yet all other columns do. However, if I later call -- p[:service] = "TwitterPublisher" -- all is well. Any ideas about what is going on? My

Disabling ActiveRecord "type" column subclassing
Hi! I have a legacy table that has a column named "type" and need to remove this automatic subclassing by ActiveRecord. The api pages are vague about this, and I tried self.inheritance_column = "xtype" which seemed to get me half-way. In the validate_on_create method, the value of self.type was my model Class name. How would you disable this feature? -- Posted via

acts_as_ferret with STI models
Can acts_as_ferret search only one of the inherit models in the hierarchy of STI models? Say you have Contents, with types articles and comments.

Serialization of ActiveRecord Instances: No Inheritance Column?
Hey, I have been looking at ActiveRecord''s serialization code, and noticed that ActiveRecord::XmlSerializer#serializable_attributes purposely excludes the STI inheritance column per ``options[:except] = Array(options[:except]) | Array(@record.class.inheritance_column).'''' Is there a particular reason for this? Would anyone be opposed to my writing a patch to have this
