What exactly is view_context? Also what exactly is happening in config.autoload and why do we have to create a module in the application.rb ? is a decorator just a class that wraps around a model or something to extend its functionality in a well-encapsulated manner so that the scope of itis separate and gives us a way to separate the concerns of an application more?

Ummm am I supposed to create a user account? I'm confused. Or are we simply logging in. because my respond_with returns nul.

Wait I don't understand why you have to tell Shrine to be able to read the file, if the file system on the AWS S3 side has already been public. I don't quite understand that.

weird. I keep on getting this error.
