redefining the method belongs_to in ActiveRecord::Base
Hi. I''ve tried to redefine the method belongs_to in ActiveRecord::Base,
so every time a model is defined as belonging to :attachment, it should
have some additional methods. I tried to do an alias of belongs_to, but
this was not successful. The error message in Webrick was

update_attributes
I''m working on a form that updates a product record and several
associated detail records.
The detail records are showing and populating okay in the form. But
when it hits the controller, I get Couldn''t find Detail with ID=detail

correct record id. Anyone have an idea how to fix this?

Possible to use attr_reader/writer in model?
I have some properties that I want setable externally, but readable only
internally. I''ve played around with attr_writer (and attr_reader
separately) but can''t figure out how to get either to work. I can do
what I want using attr_accessor, or just straight out defining the prop
setter method. Anybody know how to use attr_writer or attr_reader with a
model?
You da man,

"include" versus "extend" - what's the difference
Hi,
Just wondering when one would use "include" over "extend"? Both seem to
bring in methods to the class no?
The context is I''m just trying to understand why both are used with the
