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

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?

Integrating polymorphic models into controllers views? how?
I''m having trouble trying to get this to work.
How the heck do you get a polymorphic controller to work? Especially
integrating it with a view?
Let''s say that we have shows, and episodes, then comments.
A show has many episodes, an episode has many comments.
the route is /shows/1/episodes/1/
Now to add a comment to that episode, how would I do it? Let''s say

The parameters are "id", "firstname" and "lastname". Now, I want to

arrives at this page I display both a registration form and a login
form. However, if they are logged in then those forms should not show
up on that page. Also should

I fired up my rails app after a few weeks, only to find it was broken,
in that the variable seems to be losing it''s value somewhere between the

test, and here is what I get:

pass hash as parameter
Hello,
How can I pass a hash as parameter from a template with url_for?
e.g. : if I have
test = { :a => "a", :b => "b" }
How can I pass that with my request? Is it possible to pass nested
hash''es to?
Right now,
url_for :action => :test, test
doesn''t seem to work.
Thank you,
