For example I have table Questions. With fields id, text, and test\_id.

test\_id is not being displayed in my view. I am hoping this means Rails  
has picked up that it is an id for another model. If so, then how do I  
utilize that?

If not, then do I need to avoid ‘id’ in any field names other than the  
main id field?

Thanks!

Yes they are foreign keys. Can anyone point me to some examples of how  
to link up those realtionships in Rails?

You really should check the documentation before asking this list.

It’ll be because fields named xxx\_id are supposed to be foreign  
fields. You have to customise stuff to make that show up how you  
want… scaffold won’t do it.
