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?

DRY validates_format_of?
In a model I have following validates_format_of. Is there an easy way to DRY this up?

how to get column_for_attribute?
Hi all, In the code below I don''t understand: 1. Why I have to prepend overriden method content_columns with "self." to get it working? 2.
