How can I dynamiclly generate models?
I am trying to write a plugin, ''acts_as_commentable'', for my models -

...def define_klass(table_name)

end
end_eval
eval(class_def, TOPLEVEL_BINDING)
const_get(tname)
end
end
end
end

Anything wrong with the Dynamic module?
Sorry for the long post,

def self.define_enums(*enums)
enums.each do |spec|
