I'd suggest you use named scopes instead, allowing you to stick with
Rails conventions and benefits.
class Dic < ActiceRecord::Base
set_table_name 'dic'
named_scope :categories, :conditions => { :type_id => 1 }
named_scope :classifications, :conditions => { :type_id => 2 }
end
# Example usage
Dic.categories.all # => returns all categories
Dic.classifications.all # => returns all classifications
