Lost upgrading from 2.3.8 to 3.1.1

I have been converting from Rails 2.3.8 to Rails 3.1.1 and have made
some progress. The 2.3.8 code works fine.

I am now getting the following error and am fairly clueless where to
look.

I think I've got an error in my requires but I'm not sure.

All suggestions are welcome.

This is a huge guess. But didn't ActiveSupport change some of the
methods for finding records; so you could be getting an Arrayk where
you usecd to expect a single String?

Greg,

Tuesday, December 20, 2011, 10:52:43 AM, you wrote:

Maybe something in environment.rb then?

Hi Ralph,

I agree with Greg, there is something in your environment.rb, the stack trace points to line#6.

Can you post your environment.rb here?

This could be something to do with plugins also, i.e. if you are still using any plugins which aren’t Rails 3 compatible.
