Directly based on Kristian Ackar's package Sails-hook-blueprint-count.
Adds blueprint api method to sum values of attribute(s) on records in database. This is useful for example get a total amount of transactions. Adds also max method.
The sum function comes from here.
In Sails.js v0.11+ installed hooks are run automatically. Therefore, simply install the hook via npm:
npm install sails-hook-blueprint-sum
GET /:model/sum?where={:CRITERIA}&sum=:attribute1&sum=:attribute2
GET /:model/max?where={:CRITERIA}&max=:attribute1&max=:attribute2
"where" parameter is optional. If it's used it's used in the same way like you use it in default blueprint api find method Sails.js blueprint api find method documentation.
"sum" attribute is mandatory and errors will be raised if attributes are not compliant to the sum function. Handling of these errors is not implented yet, thus it's a 0.0.1 version.
