Clearing ActiveRecord cache

Question

I\'m building a command line application using ActiveRecord 3.0 (without rails). How do I clear the query cache that ActiveRecord maintains?

Answer 1

We use:

ActiveRecord::Base.connection.query_cache.clear
(ActiveRecord::Base.connection.tables - %w[schema_migrations versions]).each do |table|
  table.classify.constantize.reset_column_information rescue nil
end

But I am not certain even this is enough.
