When using validates_format_of I am not able to enter a nil value?
It’s a mute point that I think that validates_format_of should NOT do
the job of validates_presence_of, but how should i get around this?
I want to validate a field only if someone has entered something in,
otherwise i do not want it to validate nothing. I do not mind if he user
enters nothing, but if they intend for something to be there, it needs
the correct format.
