Validating a non-object attribute in a form via checkbox?

Hi there

A user can place an ad with various attributes via a form; however, I
want the user to check a box signifying that they’ve read the terms
and conditions for use of the site.

So the ‘terms’ is not an attribute of the Advertisement model. I
could check that the user has ticked the box in my controller but
would like to bundle this up with the validation process.

How to ensure that the checkbox is ticked before the ad object is
saved as part of the model validation?

Any clues appreciated

Should the terms perhaps be part of the user model – it could then be
part of the user validation (using validates_acceptance_of)?

Ah, validates_acceptance_of !!
That works fine and is exactly what I was after.

many thanks
