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. To view this dis...

Hi all, I have multiple textboxes containing numbers. I want to add up all the numbers and show the sum. Can I select the textboxes by class and sum the content?

...of indices corresponding to the first letter is obtained all right with gregexpr but the next step is not so clear. I am not able to figure out how I can use this information to pick out the letters from the original string. My problem is that I don?t know how I can treat the string as a vector and pluck out the letters. ? There may be many ways to do it, but I have not succeeded in coming up with even one way! I will appreciate any tips that I can get. Thanking you, Ravi

...ted to fetch the ID parameter of the newly created object, so that I can make some assertions on it. But I can''t seem to find an elegant way of doing that. Of course, might create action redirects. That means that @response.redirect_url is something like "/show/8". So I could pluck the number off that, but that seems too brittle, since if I change my routing, that would no longer work. I was wondering if there was a way to call routing on the redirect_url, so that I could then fetch the ID from the parameters hash. That wouldn''t be brittle at all. But I can'&...

...nt handlers on a per-node basis. Now, I have an init() function fire which assigns all event handling and behavioural code; when you inspect the source, all you see are intelligently named attributes. http://dev.rubyonrails.org/ticket/5266 The second half of this is #5266, a modification to the .pluck method in Prototype. Taken on its own, it might seem ho-hum, but when paired with document.getElementsByAttribute, you have the tools you need to create really potent domain specific solutions that don''t require any further inline event handling. My favourite example is for an applica...

...ere are no errors and the colours come out fine. But when I use the axis command, in the more complex code above, I get an error. The real question I want to know is how can I enable R (or my OS) to plot a greater number of colours? I can plot 820 colours on R under windows, probably more, I just plucked 820 out of the air. I'm guessing this is because my windows graphics card can produce that many colours, whereas on linux I am limited by what x-windows can produce, but there must be some way of increasing the number of colours I can plot using R under linux...? Many thanks Mick The infor...

Thanks! I can try to modify that for my needs. Any idea where can I find a list of patches? I'll look for centos specific ones that I might want to apply. The spec file you shared has a few upstream patches as well as Fedora specific ones. I wonder does one knows which patches should be applied to each release, do they publish it somewhere?
