I keep getting this error in rails 1.1, does anybody know what it means? My site will be working fine, i do some more development, get a parse error, and then all of a sudden the page 404's with the following error Session contains objects whose class definition isn't available Remember to require the classes for all objects kept in the session. (Original exception: uninitialized constant BigDecimal [NameError]) Any ideas here ? Clearing all the sessions and cookies brings everything back to normal.. not sure whats going on. This is on Rails 1.1, Linux, Ruby 1.8.4, Postgres thanks adam

You have changed your model since your sessions were created. This causes a mismatch and and the error. Each time you change your model or database your sessions will no longer be valid. That's why clearing them fixes the problem.

Thanks for the explanation. However my model and database (column definitions) were not changed here. Anything else that would cause this? All that happened was i had a parse error in an rhtml page, fixed it, i reloaded and then got this and wouldnt go away. adam

I'm not sure. I know that rails will die if you try to access an object in your session that rails knows nothing about. What are you storing in your session?
