I am struggling with Webrat and Paperclip. If I specify:
validates_attachment_presence     :image, then AR complains because 
there is no image set.

Therefore I decide to remove this validation, and instead use:
validates_presence_of :image_file_name, to trick him. But it still 
doesn't work. When I create a new object, even if I put: 
Product.create!(..., :image_file_name => 'thumb1.png'), AR still 
complains and it says that Image file name is missing. There must be 
some Paperclip magic which I can't get around.

The only solution I have found is to remove the validation of the 
attachment for passing the tests, but I'd like to keep it.

Anyone ran into this previously?
