validation + should be > 0

Hi,

my default value for variable mainimage_id is 0. I am trying to apply really basic validation. If mainimage_id is 0 it should fail and if it is > 0 it should pass the validation.

validates_numericality_of :mainimage_id, :greater_than => 1, :message => "Choose image."

This will pass the validation even if the value is 0. Thanks for your help.

You could try making the default value nil. Makes more sense anyway - nil indicates lack of data, while 0 suggests there is a default image.
