Essentially, I want to hyperlink a total count of bugs queried from the database to a method that will return the bug numbers when clicked on. I have a method, bug_total, that returns the total number to display in the

I suggest that if you don''t pass any args to ActiveRecord#pluck, it would use the select values. This follows along well with the way other AR::Calculations work. As an extra benefit we would be able to pluck virtual columns. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.

I''m trying to get our app running on Lighty... I followed Ezra''s instructions: http://brainspl.at/pages/rails_stack... Currently the app runs fine with webrick, but with lighty I get 404 errors on everything. I found if I don''t edit the lighttpd.conf file to use absolute paths, it works fine. But this is not good for production because I need to run it with the -d

Hi All, I have a slight issue getting R to plot a series of tables automatically. Essentially I have a series of tables that I wish to plot. They are named on_2, on_3 etc. based on the file name when they were read in. I have filelist <- list.files() to give me list of the table names. I wish to plot each table, so I was thinking along some kind of for loop as below: for (i in 1:Number_Files)

So I want to have a form with a drop down that lists all our customers. And when a user selects a customer, I want it to automatically list the customer names emails below the drop down. Anyone have any thoughts as the best approach to do this? I could just write javascript, but it seems like there would be a rails tag for this. thanks, phil -- Posted via http://www.ruby-forum.com/.
