When I have the subclasses in the parent class file itself I am able to  
get the names of the subclasses using \<Class\_name\>.type\_options using  
acts\_as\_sti\_factory plugin.

But if each of the subclass is a separate rb file then type\_options is  
not getting the sub class name.

Example: In my sort\_field.rb, I have

class SortField \< ActiveRecord::Base  
def self.inheritance\_column  
‘sort\_type’  
end  
end

class AscendingSortField \< SortField  
end

class DescendingSortField \< SortField  
end

Now SortField.type\_options would fetch me the names of the subclasses.

But if I have the subclasses in a separate file such as  
ascending\_sort\_field.rb and descending\_sort\_field.rb the same does not  
help.

Please help me…
