How extend model attributes?

How do I add arbitrary attributes to an AR model?

It would appear that simply adding instance vars with accessors to an AR model doesn't actually work the same way as a regular class. Quite confused by that.

The attributes derived by reflection is fine, but I have several other attributes that will not come from the data table. Most are state vars or behavior modification vars derived from config settings or application logic. These + the data table combine to make up the whole model.

Hmm, well after untold permutations, I finally struck upon the combination that works.

attr_accessor :name

Basically sets up a getter setter for the attribute so you can do self.name= and self.name.
