Promise functions for working with model entities

Promise functions for working with entity models.

  • createIntroducer: produce a function that augments objects with an id
  • introduce: pre-built introducer with an internal id generator
  • createCleaner: produce a function that removes persistence cruft


var entityp     = require("entity-promises"),
    u           = require("underscore"),
    mongocoll   = ...,

introduce = entityp.createIntroducer(anIdGenerator);  // caller-suppplied id generator
clean = entityp.createCleaner("_id");                 // remove mongo identifiers

function entity(spec) {

/* create and persist entity instance from specification.  Return a promise of
 * the persisted instance data. 
exports.create = function (spec) {

    return entity(spec)
