Thanks, I'm much closer…But, what if your user and your group both belonged an overall Union model…say Union has many users and Union has many groups…Right now I'm getting all the checkboxes and groups for the whole app, instead of just one Union?

You need put this:

attr_accesible :group_ids

On user.rb to avoid WARNING: Can't mass-assign protected attributes: group_ids

Thanks for this great post; it really helped me in getting this set up. I'm not sure I would have ever figured out how it worked without your description (I would have done a lot of extra manual handling).

Quick note on the labels. If you want to get the labels to work, set :id => "group_check_#{group.id}" on your checkbox and label_tag "group_check_#{group.id}", group.name for your lables.

re: Meme's comment

Actually I think Archie is correct about putting it in "update" action.

I tried putting it in "edit" and all it does is empty out the checkboxes upon reaching the edit view, leading me to think that line is meant to be processed AFTER the edit data is submitted (which makes more sense when I read that line).

I moved it into "update" action and everything is behaving correctly now. I had no need to modify either "create" or "new" actions.

As for Archie,

You have to place that in "new" and "edit" controller
