Validation with has_many
I have two problems. I have a comment that has_many uploads. Before
saving the comment, I want to be sure that the upload(s) has passed
validation, but I also need to validate in other ways. For example, I
do not want to save the comment if there is no comment or upload. Or, I
do not want to save the comment if the image has been uploaded
previously (comparing md5s with past upload md5s
