But when I try to use lighttpd i can access http://localhost:3000/images/rails.png for example but not a dynamic page. In the latter case I dont get any page, the browser is just waiting infinitely.

OK, I''m diving into new things - a .net programmer and windows user trying to develop in Rails on my Mac. Initial setup was easy, and I had things working and was thrilled with myself. Then I shut down. Next time I booted up, mysql was acting all kinds of funny. I finally got that working again (I *think* it mostly had to do with me not having the right path, I unfortunately

Hello, Thank you for the fast responses, I really appreciate. I really enjoy being a part of such a great community. I still could not solve my problem.

Trying to get Rails and mysql running on OS X, and I''m a Nuby. Everything ran smoothly when I first installed, but after rebooting things were out of whack.

To all fellow Dreamhosters out there... Sometimes my app mysteriously loses its connection to the database, resulting in a big ugly "Application Error (Rails)" page. Usually refreshing the page makes it go away, but not today. :-( In production.log I see this: MysqlError (Lost connection to MySQL server during query): Any idea why this happens? It''s rather intermittent

I set my app on the Rails edge yesterday via rake freeze_edge and that broke my app. If I take the ..\vendor\rails folder out and restart the server (webrick), it works fine. I don''t get any errors. But if I re-add the ..\vendor\rails folder I get errors when accessing any views that have pagination. Is this a known issue or problem? This is the error: ActiveRecord::StatementInvalid in

Most likely due to something I misconfigured and/or broke when trying to get the new polymorphic acts_as_taggable to work...In short, after installing that gem and then trying to run gem install mysql on my windows server, I''ve been getting this weird error on every page I try to hit. If anyone give give me any insight into how I messed this up or how to fix, it would be much

Hi everybody, I''ve been reading lot of material about Ruby on Rails, and it looks like really rocks.

I ran the usual "sudo gem install rails --include-dependencies" to upgrade and now my development environment is all out of whack. I suspected MySQL, but I''ve already made sure I was using the

I''m sorry guys. I''m really still such a newbie at this. i''ve been having trouble getting my Rails apps to run on Dreamhost, and I think it might be a problem with the database connection.
