What a great addition to Rails. Thanks for documenting it Chris!

In case this helps anyone (I had a hell of time troubleshooting this):

I ran into a really frustrating issue when I pushed to Heroku. Rich text (trix) with image uploading was all working fine locally, but on Heroku dropped-in images weren't saving, and the issue had to do with my using Amazon S3.

Turns out it was a CORS issue, which Chris made a video about here:

In addition to that, I had to set my CORS configuration in my S3 bucket settings. This was the configuration that ended working for me:

<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
  <CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>POST</AllowedMethod>
    <AllowedMethod>PUT</AllowedMethod>
    <AllowedHeader>*</AllowedHeader>
  </CORSRule>
</CORSConfiguration>
