问题
I have an application that I am considering porting to Sails.JS.
One of the big issues I am having is supporting the per-request database selection that we have right now.
Our app creates/uses a different database for each customer that we have and we select the database based on the request.
How could I achieve that in Sails.JS?
Could I write a Express middleware that would do this on a per request basis?
