similar to: Re: help with link_to_if, I can''t make it work..

I just got a new Debian Sarge server and followed the brainspl.at "Debian Lighttpd Rails Stack" tutorial. The only place I deviated was the version of Lighty. The page uses 1.4.7 and I spotted that 1.4.10 was available. I installed that and couldn''t get anywhere. Lighty died on first access from the test rails app, and even from a ultra basic static config. No log,

I''m looking for a way to check an item in memory to see if an association loaded. I load the association in the controller and then in the view I need to check to see if the associated model loaded because I display an attribute of it.

Hello Puppet Users ! We encounter a problem with the dashboard on this URI : /reports/changed The /reports works fine with ~130000 reports (up to 3 months and auto-cleaning with rake reports:prune job) I make a reports:prune:orphaned, juste in case, but without any success.

People, I am using: before_filter :login_required in my Controllers and this works fine.

hi, simple issue i''m sure--i''m a ruby & rails nooby--but for some reason the sample app that i''ve been running/building from the Agile Web Dev w/ Rails book changed from a (nicely) formatted HTML page, with a link that would try to show my application status, to the text i list below--with the first line in larger typeface than the rest, but otherwise plain
