similar to: Finding the position on an item in a collection

I have a model object that acts as a list. The position of each object is determined by two factors: number of votes ascending and age of object descending. When a user adds or deletes a vote I need to quickly update the associated model object''s position. Right now this is done with the following method: def update_position position = nil Bug.find(:all, :order =>

Very new to this but would appreciate a hand as this is driving me mad, I''m trying to update both degree and assigned from a single form, the degree section updates fine but assigned just retains the same values, any help much appreciated! my edit.rhtml file looks like: <h1>Editing degree</h1> <%= error_messages_for :degree %> <%= start_form_tag :action =>

When using array.each_with_index how do you start at a desired index position? I can do it like this, but its not very clean and doesnt seem efficient : desired_index_start = 20 array.each_with_index do |value,index| next if index<desired_index_start end Thanks Chris -- Posted via http://www.ruby-forum.com/.

I always need to apply alternating item styles when outputting a collection, here''s what I''ve been using recently. In the app helper I define this method: def alternate(items,alt=false items.map{|i| i.class}.each { |k| k.class_eval {attr_accessor :alt}} items.each { |i| i.alt, alt = alt, !alt } end When I call the partial I wrap the collection with this method:

Disclaimer: Ruby newbie at work Thought I was going so well. Wanted to produce a select box from an array constant, with the indices returned as values , and the array values used as the descriptions. Checked out Ruby RDoc and saw there was an each_with_index method and came up with: <%= select (''type'', ''typecategory'', Typecategory.each_with_index

Given an array, I''d like to iterate over it with a counter to produce something like this from a template: foo.0 = ARRAYVALUE0 foo.1 = ARRAYVALUE1 foo.2 = ARRAYVALUE2 (where ARRAYVALUEn is replaced by the value, and the foo.n is incremented for each value) The puppet templates support iteration, but I don''t see how to also increment a counter to get the behaviour above? Is

Does ruby have anything where if I''m going through a do-while loop, or a "3.times" loop or "for product in products" where there''s a variable that will tell me which iteration of the loop I''m on? Instead of havign to declare my own counter = 0 and then increment it each time? Seems like something Rails would have... I can''t seem to find

Hi I have previously used railscron for server-side manipulation of the database but had a heap of trouble working with it. BackgrounDRB was suggested to me by a friend. I upload some files via acts_as_attachment and these go lie in a dir structure that i desire.

I''ve spent hours researching the subject and have tried many test sequences in IRB, and rails console but I''m just having trouble making headway into what is probably a very easy subject. I understand arrays with at least 4 other languages but with Ruby I haven''t found a mental connection with how I can assign variables to arrays.. Take for example: def

I''ve been messing around with Ferret (no punn intended). After spending some time testing it out (indexing to file), I decided to index about 10% of the data I want to eventually index. It took several hours to complete the index on my local machine, but it was created without any problems and after optimising it the searches returned results at the sort of speed I was expecting. I
