Let’s say I have table ‘groups’ and table ‘members’.

When SHOWing a particular group I included the form for members (Add  
new).

What approach should I use for making sure that members add to the group  
being shown?

I could create a hidden tag (group\_id), but I want to know how others do  
it in Rails.
