After the post on my dojo.io.bind experience, here's what I learned in using S3. I'm using the S3 library for Ruby
published by Amazon.
When you save an entry with a file attached in MyOwnDB
, the Rails action handling the form checks the size of the file. If it is within the limits allowed for the account, it saves the information needed locally in the database (let's say in the table "files"), and then saves the file on S3.
