1) backup production database:
	heroku pgbackups:capture --expire --remote production

2) obtain url string to backup from step 1:
	heroku pgbackups:url --app production_app_name --remote production_app_branch_name

3) transfer backup from production to staging app:
	heroku pgbackups:restore DATABASE 'production_app_backup_url_string_from_step_2' --app production_app_name --app staging_app_branch_name

Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.
