Re: [Rubycocoa-talk] activerecord method/column name conflict

Hi Pim,

This is because #description is the #inspect method in Cocoa.
What you could do is override it with the correct arity on the proxy  
and make it return the correct value:

class ProjectProxy
   def description
     @record.description
   end
end
