similar to: each_with_index. Can you start at a desired index position?

Hi, using Rails 1.0 on windows (without svn yet) I just wrote "rake freeze_edge". Are the RJS-templates already included then ? When I write "rake update_javascripts" I receive this error: svn: ''.'' is not a working copy Any tipps for a newbie on how to get the update done (if neccessary) ? thx Jan

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 =>

Hi, Is it possible to populate the development database from the test fixtures? I''m trying to keep the development database schema in a plain-text sql file and modifying that when I need to modify the database structure. However, then I have to either manually repopulate the database or add in additional sql statements that populate the test database. It seems like it would be useful

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

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 have a section of javascript which i''m trying to use to dynamically generate the options for a mult-select box, when another box''s contents are changed. Basically i have a method that returns an array of arrays, where each array is of the form [name, number] I then iterate over the arrays, and substitute in the values out of the array -

My BackgrounDRb server intermittently bails out with the following exception in the middle of a long running task running on a Worker sub classed from BackgrounDRb::MetaWorker (the point at which it raises this exception is different each time it runs) /opt/local/lib/ruby/gems/1.8/gems/packet-0.1.5/lib/packet/packet_core.rb:145:in `schedule_write'': You have a nil object when you

Well, the worm has turned and I think I may actually get an Apple ;P. But I can''t decide which one. Pros and cons: 14" iBook: + modem (for when broadband kicks out, or on the road and there''s no WIFI) + screen is probably big enough (though I currently have a 15" Dell) + doesn''t get as hot as the MacBook + almost half the cost + less likely to get stolen -

Hello there, I working on my tests but I getting this strange errror: I can see on the database that the object was created but I still got an failure on my test. this is my test code: test "should create artist" do assert_difference(''Artist.count'', difference = 1) do post :create, :artist => { } end assert_redirected_to

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

Dear all, I have this line: <% $c_repo.split('','').each_with_index do |repo, i| %> in one of my template files and on the target node I''m getting this error: err: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed to parse template zmfs/zmfs_prob.erb: private method `split'' called for nil:NilClass Any idea what am I missing?

I have a form that I want to use to update multiple objects.
