Update attributes for multiple objects

Hi everyone,

I've been thinking and googling about this for the whole afternoon and I dont find the solution, but I know there must be an easy way (after all this is rails):

I have an page where user objects are listed (e.g. customers) and they have several attributes (like name, e-mail etc.) and a special attribute called contacted (which can be true or false depending on if this customer has been contacted by the sales people or not)

No big deal I thought, just write two controller methods 'set_contacted' and 'unset_contacted' and we are done by passing over the IDs of the corresponding objects. But then there came in two more attributes and I suddenly end up with 6 controller methods which feels horrible wrong to me (Not even to mention the DRY principle violation).

What I would like to do is the following using checkboxes and a form for the whole table and a submit button in order to save the changes made to the user objects

User | contacted user1 | user2 | user3 |

[ Save changes ]

You sometimes see a similar behaviour in Webmail clients where you can check serveral e-mails at once and then hit a delete button.

Any sort of help is appreciated! Have a nice week-end

Matt
