Smarter paperclip validations

Question

I\'m using paperclip in a rails app and have the following three validations in my model

validates_attachment_presence :photo                    
validates_a         


        

Answer 1

validates_attachment_size :photo, :less_than => 1.megabyte, 
  :unless => Proc.new { |imports| imports.photo_file_name.blank? }

Answer 2

I think you can do it other way. Don't mess with validations. You probably have something like this in your form:

<%= f.error_messages %>

You can remove it and write your own helper to display error messages. Errors are stored in hash:

@photo.errors

Or if you want to get to them through form builder:

f.object.errors
