Hi:

I would appreciate some hint. I can’t modify Class A1 but I can subclass  
it so I wonder how can I get access to its belongs\_to and has\_many i.e.

Class A1 \< ActiveRecord::Base  
belongs\_to : B1  
belongs\_to : C1  
has\_many :D1

end

Class myClass \< ActiveRecord::A1  
end

The above doesn’t work… Well it doesn’t do the insert …

MyClass and A1 table are exactly the same. Any suggestions?

Regards.

Try to write the second class as

Class myClass \< A1  
end

Class A1 It is not in module ActiveRecord, is it?
