I have following many to many relationship:  
class Service \< ActiveRecord::Base  
has\_many :service\_dependencies  
has\_many :dependents, :through =\> :service\_dependencies  
end

class ServiceDependency \< ActiveRecord::Base  
belongs\_to :service  
belongs\_to :dependent, :class\_name =\> ‘Service’, :foreign\_key =\>  
‘dependent\_service\_id’  
end

However, in my schema the MTM table service\_dependencies has few  
relationship attributes as well, e.g. impact, severity, etc. along  
with the foreign keys.

Right now, I’m displaying the dependent services’ fields in following  
manner:

\<% for dependents in @service.dependents %\>  
**Service Name:**  
 \<%=h dependents.send(“service\_name”)  
%\>  
  
\<% end %\>

I want to display the relationship attributes, impact, severity as well,  
could someone please help me by letting me know how to access them in my  
view page?
