Hi!  
In my application I have Route model. In migration I have to make some  
operations on all routes, however simple Route.find(:all).each does not  
work:

rake aborted!  
undefined method `find’ for  
#ActiveRecord::ConnectionAdapters::MysqlAdapter:0x8d9c2c4

Well I ran on this issue back in January and found that there is some  
name conflict since when I run this code in migration:

puts ActiveRecord::Base::Route.superclass  
puts ActiveRecord::Base::Owner.superclass

Result is:  
ActiveRecord::Migration  
ActiveRecord::Base

In January I have used dirty hack, stopping migration and running  
external script. But I have to make some changes again, which require me  
to update all routes. Is there some proper way to call Route.find(:all)?

Maybe I have to get used to external script or rename model from Route  
to something other?

In case someone interested in details here are they:
