Hey all, with ActiveStorage coming out very soon I am very quickly finding
a need for some validations for attachments before storing. Some very quick
validation helpers would be great for example content type and size would
be huge wins in protecting an application that is expecting to only allow
images.
Just a quick example:
class User < ApplicationRecord
has_one_attached :avatar
validates :avatar, attachment: { content_types: 'image/*', size: 50 }
end
