Validating the Content-Type of Active Storage Attachments

Full validation support for Active Storage attachments won’t be arriving until Rails 6. Until then you’ll need to write your own custom validators to add this missing functionality. Last time I showed you how to write an attachment presence validator. Next I’ll share a validator which can restrict the content-type of your attachments. Drop this bit of code and its accompanying RSpec matcher into your project to tide you over until the next Rails release. http://www.carlosramireziii.com/validating-the-content-type-of-active-storage-attachments.html

Adding an Attachment Presence Validator to Active Storage

If you’re using Active Storage, you should know that it does not (yet) provide a way to validate the presence of an attachment. Unlike Paperclip or the other popular file upload gems, there’s no validates_attachment_presence method you can use. Luckily it’s pretty easy to roll this out ourselves. I’ll share the custom validator code that I use to add in the missing validator in this post: http://www.carlosramireziii.com/adding-an-attachment-validator-to-active-storage.html
