Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_symbol, *arguments) ⇒ Object

# Raise NoMethodError if the named attribute does not exist in order to preserve behavior expected by #clone.

def attribute(name)
  key = name.to_s
  if self.class.fields.has_key?(key) #TODO check not symbols
    get_attribute(key)
  elsif self.class.associations_keys.index(key)
    get_association(key)
  else
    raise NoMethodError
  end
end
