Rails - Paperclip validating attachment size when it shouldn't be?

Question

I\'ve got a rails model using Paperclip that looks like this:

  has_attached_file :image, :styles => { :normal => [\'857x392#\', :png] },
                          


        

Answer 1

validates_attachment_size :image, :in => 0.megabytes..2.megabytes

works now

Answer 2

Paperclip's validation only checks the range, and doesn't care about the :allow_nil => true

What you can do is try to set :min => nil or :min => -1, maybe that will work.

Update: This will not work in the latest version of Paperclip since they have changed how validations work. What you could try instead is:

validates_attachment_size :image, :less_than => 2.megabytes, 
   :unless => Proc.new {|model| model.image }

Answer 3

validates_attachment_size :image, :less_than => 25.megabytes, 
                          :unless => Proc.new {|m| m[:image].nil?}

works perfectly for me
