custom paperclip validation error message

Question

I have this validation for content type:

validates_attachment_content_type :photo, :content_type => /^image\/(jpg|jpeg|pjpeg|png|x-png|gif)$/, :message => 'file type is not allowed (only jpeg/png/gif images)'

I want only the message above to be displayed but instead it says

 Photos photo content type file type is not allowed (only jpeg/png/gif images)

because its a photos model and attached file photo.

thanks

please note that you need to add a condition to validation: validate :check_content_type, if: ->(){ image.present? } – Nickolay Kondratenko Dec 13 '13 at 09:58

I'm late to this party.

validates_attachment_size :image, :in => 0.megabytes..2.megabytes,  message: " is too large, try less than 2mb  or for help"

Gets you:

Should get you closer to home, with an output of:

"Image file size is too large, try less than 2mb"
