Devise is one of the most famous Ruby gems, which is a flexible authentication solution for Rails based on Warden. It comes with a lot of useful features, but it also has its limitations.

I recently had to upload an image to an API endpoint in Rails, and did not found that much material online, so I decided to write this article describing how I managed to do this.

I was building an API that had to interact with an authentication micro service, where the request parameter was a Multipart image of a user file that should then be encoded in base 64 and get uploaded to AWS. Continue reading
