Strange regression in 3.0.14

I updated an application from 3.0.10 to 3.0.14, and now I'm getting an error of

NoMethodError (undefined method `collect' for #<Mysql::Result:0x9b89bc0>):   app/models/attachment.rb:20:in `set_uid'   app/controllers/attachments_controller.rb:24:in `create'

It's being triggered by the call to Attachment.find_by_uid in this method, which is called in a before_create callback in attachment.rb:

  def set_uid     code = Array.new(7) { (('A'..'Z').to_a + (0..9).to_a)[rand(36)] }.join.to_s     if Attachment.find_by_uid(code)       return self.set_uid()     else       self.uid = code     end   end

This works perfectly in 3.0.10, and fails in 3.0.14. One other wrinkle, this is using the mysql (not mysql2) adapter, as I can't get mysql2 to build on my Joyent SmartOS server.

I met strictly the same problem. Have you a solution?

No, nothing yet. I am trying a new server as soon as I have time to migrate, but for now I am living dangerously!

Found the cause:

https://github.com/rails/rails/commit/a5a0338b9b3f2f24efde0ae6a56e99b938eff7cf

And its resolution: Rails 3.0.15 was discreetly released some days ago.

Yayayayayayaa!

Thanks for the find!
