Form - Tick boxes in related table

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 http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#M001573

There is also Nested Object Forms in Rails 2.3 http://guides.rubyonrails.org/2_3_release_notes.html#nested-object-forms
