Woops, clicked enter by mistake.
The error comes because it's looking for a file `follow.html.erb` in your
app/views/<controller>/ directory. In your `follow` method, you do not
direct it anywhere, or tell it to render any other view, so that's what
it's looking for. Did you want it to go somewhere else?

The only redirect in that method happens if there is no logged in user. The
rest of it sets the flash, then falls through to the standard render.
By convention, a controller action will render a template with the same
name as the action plus the format extension (html in this case) and
handlers.
