Hi

Why does a failed “validates\_acceptance\_of” create a hidden input in  
the view?

cheers, jason

They don’t!

You need to show your code so we can see what you did wrong!

actually, yes i think they do… check\_box has the habit of making a  
hidden input to represent the ‘unchecked’ value. not sure why, maybe  
it’s necessary to the rails internals, but the absence of the field  
from params should be enough IMO to know it’s not checked.
