Hi, Can anyone please point me to some docs on Enumerable. I can''t seem to find anything on how to use it. Thanx -------------- next part -------------- An HTML attachment was scrubbed... URL: http://wrath.rubyonrails.org/pipermail/rails/attachments/20060327/0825d5e8/attachment-0001.html

Hello everyone. I am not sure if this is the right place to post, please redirect me if there is a mailinglist more specifically dealing with prototype.js. After playing around with the very inspiring prototype library I have found a rather annoying thing, that makes the usefulness of the Enumerable mixin for Hashes questionable, if I am not totally wrong (again :-). Here an example:

Hi and sorry if this has already been discussed. I''m new on theese lists, and I couldn''t find a way to search through them. I have been looking at the sources of script.aculo.us and I''m rather impressed by the Enumerable class. What I don''t get is why you choose to extend Array.prototype with this addon. It seems like a rather intrusive thing to do, if the code

This might seem like a really daft question, but I couldn''t find an answer anywhere. How do you add something to an enumerable object? Something like var first = $A(getElementsByTagName(''td'')); var second = $A(getElementsByTagName(''tr'')); first.PUSH(second); where the PUSH is something unknown. am i supposed to use inject here in some way? Andreas

Hey guys, I recently published an article documenting some of the more useful and interesting parts of Prototype''s Enumerable, Hash and Array objects. You can find it here: http://encytemedia.com/blog/articles/ 2005/12/07/prototype-meets-ruby-a-look-at-enumerable-array-and-hash If you have any feedback or suggestions, fire away.

Hello, I have some satellite tag time-at-depth (TAD) frequency data that I would like some help with. The data was transmitted via satellite as percent time spent in each of 7 depth bins (0m, 0-1m, 1-10m, 10-50m etc.), binned over 6-hour intervals. I categorized each row of data corresponding to a date and time into summer vs. winter, and day vs. night, and then summed and averaged the given

Ok let this be a lesson to the general public. If you want to look as idiotic as I do right now do the following: Stay up all night and attempt to debug code the next day without coffee Patch the wrong file RAILS_ROOT/scripts/backgroundrb/start instead of one in plugin dir. Create a patch in the right location containing nothing but an extra space Send it to the whole Ruby community AND file a

Does anyone know the difference in performance between an ActiveRecord::find and Enumerable::find (or detect since ActiveRecord redefines the find method) for a has_many association? Here is an example: I have a list that has 10 lines and I want to find the first blank line. Which approach would be better? list.lines.detect { |line| line.content == nil } or

I am using Prototype 1.6.0.2 on Firefox 3.0b4. The following does not work when I enter it in Firebug: $A([1,2,3,4]).each(function(n) {alert(n);}); The above is just an example. Any array, using $A and any enumerable method, returns the following: TypeError: iterator.bind is not a function Seems like some objects are not being extended correctly? Using Prototype 1.5.0 on Firefox 3.0b4, this

I need to simulate an enumerable class (well, it has one method: each). The code looks something like this OTTOMH: class Processor def initialize(input, output) @input = input; @output = output end def run @input.each do |row| @output << ProcessorEngine.new(row).process end end end This is the best I could come up with: @input

Folks, I''m going slightly crazy here - I implemented a Sweeper in an older app and used nearly the same exact code in my new app, yet I keep getting this ''value must be enumerable'' exception. Even after I cut most of the code away, I still get the error. If anyone can help, I would be much obliged. Notes: I''m using Engines... wonder if that could cause a

Hi folks, I''m in the process of converting a Test::Unit functional test to RSpec, but I''ve run into a slight problem. I tried looking through the documentation but I still don''t know what I missed. Thanks in advance, Blake describe VenuesController, "on update" do before(:each) do @venue = mock("venue")

I have a very strange problem here. I do not get this. So any help is greatly appreciated. Basically I have a model that calls a method in the background process in the "after_save" method. Let''s call the model products. So what happens is this: 1. I create a new product. 2. Everything works and the product is saved with id 13. 3. A method is called in my background

Hi List! I am using the latest version of prototype.js from the SVN, including the wonderful $$ operator to loop through a number of elements with a certain classname. In Firefox everything works fine, no JS error, but in IE I get an error in the .each function saying that an Object was expected. What I do is function initializePlugins() { $$(".plugin").each(function(plugin) {

I''ve tried tackling this many ways on my own and can''t find a good solution: Breaking it down to something simplier... Venue has one address Person has one address Address belongs to state Assuming I don''t want to do tables for venue_addresses and person_addresses. What is the best way to model this using rails... big thing here is i want to be able to reuse a

Hi. In this setup "account has_many :consultations". Can anyone explain the following behaviour to me? Rails 1.2.2. The "sum" method should return 0 for an empty array. >> a = Account.find(1) => #<Account:0x39c80a8 @attributes={...} >> a.consultations => [] >> a.consultations.sum(&:foo) ArgumentError: wrong number of arguments (1 for 2)

class Event < ActiveRecord::Base belongs_to :venue belongs_to :category end class Venue < ActiveRecord::Base belongs_to :city end class City < ActiveRecord::Base belongs_to :state end I want to retrieve all event records belonging to a state. Coming from hibernate background I tried something like this: def self.list_for_a_state(state_id) find_by_sql(["select e.*

I have in my view the following: <% 0.upto(@num_performances) do |idx| -%> <%= text_field ''performance'', ''city'', :index => idx, %> <%= text_field ''performance'', ''venue'', :index => idx, %> <% end -%> and in my controller I have: @performance = [Performance.new("city" =>

Hi, In my user_controller.rb, I have the following method, which is supposed to send the user to their profile, dependng on what "role" they are (the roles correspond to the other controllers: venue, band, fan): def login if request.post? if session[:user_id] = User.authenticate(params[:user][:login], params[:user][:password]) flash[:message] =

Before I waste more time trying to figure that out, I was wondering if it''s even possible? The Rails Way says that observe_field by default will trigger changes in text fields and text areas, and on clicks for radio buttons and check boxes. So perhaps I''m using the wrong tool here?
