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

If anyone give give me any insight into how I messed this up or how to fix, it would be much

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

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.

With previous versions of active record (prior to version 1.13.2), one could simply comment out the "require ''active_record/vendor/mysql411''" line in mysql_adapter.rb to fix this problem when you weren''t (and/or couldn''t) use the native mysql bindings. However, this line no longer exists, and I''m stuck on getting any sort of applicatino

Hi, I have an application that is running fine on two different machines, but when I ported the code to a third machine, it doesn''t seem to work.

Hi, I''m having a bit of a problem with a rails app and I wonder if anyone can help. It seems to run fine for a while, but if it''s left running too long (left running as a fastcgi or webrick process that is) it starts failing with an "ActiveRecord::StatementInvalid" error (i''ve included the full error from the log file below).
