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 AND (details.product_id = 38). The :detail params seem to refer to the correct record id. Anyone have an idea how to fix this? Here''s the

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, Joe

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 > Booting WEBrick... ./script/../config/../lib/ActiveRecordExtensions.rb:67: undefined method

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 acts_as_audited plugin: Full extract from plugin (used within here): ================================================== # Copyright (c) 2006 Brandon Keepers # # Permission is hereby

Hi all I''m creating a shop page. I have a cart model that looks like the following: class Cart attr_reader :line_items def get_line_item id @line_items.each do |l| return l if l.id == id end end def initialize @line_items = [] end def empty! initialize end def empty? return true if @line_items.empty? false end end And I have some

I''m trying to use respond_to to redirect visitors who have JS turned off to a different page. The problem I''m having is that respond_to is sending *everybody* there. It''s not recognizing that JS is turned on in the browser. The wanted_html.rhtml file below is rendered whether I''ve got JS turned on or off. I''ve looked at the Accept headers being sent

I''m attempting to set up a rails app so that I can add rhtml files without having to create controllers for each one. I want a simple solution to serving static-like rhtml files as well as those with a little logic. The solution I found is this one: I added the following controller static_controller.rb ##################### class StaticController < ApplicationController end I

Is it possible to emulate a unionfs with zfs and zones somehow? My zones are sparse zones and I want to make part of /usr writable within a zone. (/usr/perl5/mumble to be exact) I can''t just mount a writable directory on top of /usr/perl5 because then it hides all the stuff in the global zone. I could repopulate it in the local zone but ugh that is unattractive. I''m hoping

Hi, I''m new to Rails, sorry if I''m repeating the question, but I couldn''t find a solution for my problem so far :( I''m using Apache2 as the web server of my Rails application. I keep my images in public/images and tried inserting images to the page like this; <%= image_tag "rails.png" %> But the image is not displayed on the browser. Can

I installed it once but it always come up with a change a path error. Let me know where to install them as well (whether to install all inside wamp or just inside c) I think it doesn''t need to have wamp as it has it''s own server. Pls let me know as it''ll be really helpful for most of them with troubles installing rubyonrails -- You received this message because you

I''m trying to figure out an elegant way to do this: I have the following three tables: people, employer, employees And consequently the following three models: class Person < ActiveRecord::Base end class Employer < ActiveRecord::Base has_many :employees end class Employee < ActiveRecord::Base belongs_to :person belongs_to :employer end I want to be able to say:

Hi -- Registration for RubyConf 2006 is still scheduled to open on August 2, in the early evening Pacific (US West Coast) time.

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 that the

I''m using Rails-1.1.4 with Ruby-1.8.4 So let''s say I have 2 model classes: class Item has_and_belongs_to_many :things end class Thing has_and_belongs_to_many :items end i = Item.new i.things << Thing.new( :value => "Something").save i.things << Thing.new( :value => "Something Else" ).save i.save Fine, now I have two records in the
