What Options Can Be Passed to the Active Storage #variant Method?

When Rails adds a large new feature like Active Storage, it takes some time before good Internet resources and documentation become available for it.

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
