Sure this one is solved somewhere, but couldn’t find it.

I have a table which has a related table (has many through). I wish  
to choose 1 or more items in the related table with a check box. For  
example, if I had a table with group one, group two and group three  
and a list of clients. I would like to have a form so that given a  
client, (in the edit client form), I can assign a client to one or  
more groups.

How would I construct a form to achieve this using a reasonable  
succinct controller?

Many thanks,

Mike

Have a look at fields\_for which you can use for linked models

There is also Nested Object Forms in Rails 2.3
