similar to: Values broken converting from rails into javascript

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

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 =>

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''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

Dear List: We installed Dovecot v1.0.0 a couple days ago. After running the software for a couple days, the following happened: Jun 6 15:58:10 cello dovecot: POP3(sgtdohara): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Jun 6 15:58:10 cello dovecot: POP3(dorene): Disconnected: Logged out top=0/0, retr=1/4652, del=1/1, size=4635 Jun 6 15:58:10 cello dovecot: Lost login process

Thanks for the suggestion, Ben. This seems an excellent approach to the problem, except that I''d been under the impression that one could only call render once. If you call it multiple times as the each_with_index loop iterates, are the results just combined automatically? How does that work? Thanks!

I''m using a web service to retrieve an array of results to a search and a render :partial to display those results to the user, while at the same time putting the results into the session. Is there a way for my _book.rhtml file to have access to the index of the result currently being displayed, like each_with_index makes available to its block? This would allow me to have the

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
