validates_presence_of
I am just going through the book and I come across a problem with the
code in the app/models:
validates_format_of :image_url,
:with => %r{^http:.+\.(gif|jpg|png)$}i,
:message => "must be a URL for a GIF, JPG, or PNG image"
It seems to moan when it''s empty even though I removed :image_url from
validates_presence_of. How should I make it optional?
