Every once in a while, I pipe up and whine that "belongs_to" should really be ''refers_to" [http://dev.rubyonrails.org/ticket/2130]. It''s time again. I''ve got a bunch of stuff going onto eBay, so, like any good engineer, I don''t just post it manually: I design a Rails-based inventory database that creates a semantically-correct XHTML/CSS auction posting...

I am very confused about where to put the belongs_to and the has_one (and other relationship identifiers).

I have two classes, Listing and Warranty. A Listing (think of it as a product) may or may not have a Warranty from a lookup table. When I want the Warranty.company for a given Listing I want to say the following: @listing = Listing.find(4) @company = @listing.warranty.company In order to do that I did the following: class Listing < ActiveRecord::Base belongs_to :warranty end and

Some of my earlier questions may have hinted ever so slightly in the direction that I''m trying to implement "enumerations". By an enumeration here I mean a class that has a fixed number of immutable instances, which in turn have essentially only a name and a position. Requirements I''ve tried to meet are - Enumeration instances should only be loaded once from the
