How do you specifiy a relationship between a many to many  
decomposition table?

I have been experiementing with has many through etc but i cant seem  
to get it working…

My tables are student and award and the ‘relationship’ table is  
‘certificate’.

Thanks for any responses

Have a look at the rails guide on ActiveRecord associations at  
[http://guides.rubyonrails.org/](http://guides.rubyonrails.org/). It has many examples.

One of your problems may be that the table names would conventionally  
be plural (students, awards and certificates). Stick to the rails  
conventions and life will be easier.
