I'm frustrated with validates_presence_of. I have a form, and I'm
validating four fields using validates_presence_of..
It works fine, except that when the form comes back with the error
messages, it is blank. If a user enters three of the four required
fields and submits the form, they get back a blank form with an error
message and have to re-enter everything.
It seems to me like there must be an easy way to fix this, otherwise
v_p_o is a total joke.
I've googled my head off to no good effect. Can anyone offer advice?
