So it's pretty clear you can require a field like title below:
fields do
timestamps
title :string, :required
event :string
end
but what if I wanted to require an attachment using paperclip-with-
hobo?
I already have an photo attachment setup as below:
has_attached_file :photo, :default_url => "/images/blah.jpg"
but I have no idea how to REQUIRE that a user uploads an image. Any
ideas? possible solutions?
