[Rails] Re: Rails 3 - polymorphic associations problem with ActiveRecord::Relation

After digging a bit deeper we were able to solve this issue.

The details of the fix are explained here

http://stackoverflow.com/questions/4522288/rails-3-activerecordrelation-random-associations-behavior

The code examples there apply only to rails 3.0.3, but the idea should
be the same for any other rails 3 release.

Basically the belongs_to association files are using the old finder
methods. these old finder methods seem to return an
ActiveRecord::Relation object at random times.

Our solution was to override the find_target method and change the
finders used for the new Rails 3 format (where(...), etc) through a
couple of initializers.

Hopefully similar corrections will be applied to the next rails
release.

Regards
