*sigh* I wish there was an option on the helper. Oh well. I ended up leaving things as-is on the view and just handling it on the model. It's not ideal, but it works. Basically, as I read through the array of attribute hash sets, I only process them if it's a full set... i.e., in the above case, if there is no key :name (which is required), then I skip processing the hash.
Eventually, I might consider a better solution... perhaps overriding the checkbox helper to provide an option to suppress the hidden tag or something like that. -Danimal On Oct 10, 6:00 pm, Frederick Cheung <[EMAIL PROTECTED]> wrote: > On Oct 10, 9:26 pm, "Pardee, Roy" <[EMAIL PROTECTED]> wrote:> I don't suppose > it's as simple as not calling the check_box helper from the form object > you're getting out of fields_for is it?
