I'm looking for the simplest way to *automatically* downcase the attribute names of Models mapped to legacy tables that use upper case. eg: class Workorder < ActiveRecord::Base set_table_name "WORKORDER" end which has "NAME" as an attribute can use "name" as an attribute. currently: workorder = Workorder.find(1) workorder.NAME # => "workorder 1 name" I want: workorder.name # => "workorder 1 name" Thanks, Jamie

You can add a getter/setter for each attribute like: class Workorder < ActiveRecord::Base set_table_name "WORKORDER" def name self.NAME end def name=(theName) self.NAME = theName end end I've never used this myself so I may have the syntax wrong. However I believe the concept is sound. Although it is not "automatic" as you would like.

I ended up overriding method_missing in an abstract Model class. Since ActiveRecord::Base's method_missing is private, I ended up copying the whole thing and putting the modified version in my subclass. Basically, since I know the column names are upper case, I just look to see if method_name.upcase is in the model's attributes hash and if so, upcase! the method_name and pass it along. I've documented this here: http://blog.dangdev.com/articles/2005/11/30/active... table-column-names Looking forward to comments or a better way to do this. (What I would really like is to convert the attributes to lower case as they are set.) Jamie

Yeah, but I didn't want to hand code all those accessors--was looking for an automatic way to deal with the problem. Thanks, Jamie
