Is there a way to enforce integer values on a number

[bingomanatee]

I want whole number (integer) values in a field - is there any way to
enforce integer properties on a number field in the schema?

I think there are a few ways, depending on whether you want to enforce it (via validation) or quietly round non-integer values (with a setter). Personally, I use the setter approach, e.g.

var mongoose = require('mongoose');

var util = require('util') ;

mongoose.connect('mongodb://localhost/ex_simple') ;

var intHolderSchema = new mongoose.Schema({

  'integer': { type: Number, set: function (v) { return Math.round(v) ;}}

}) ;

mongoose.model('intHolder', intHolderSchema) ;

var intHolder = mongoose.model('intHolder') ;

var int1 = new intHolder({ integer: 3.1415 }) ;

util.debug(JSON.stringify(int1)) ;

int1.integer = 10.543 ;

util.debug(JSON.stringify(int1)) ;

mongoose.disconnect() ;
