Description

Simple and easy-to-use NodeJS Mongoose Schema plugin to find random documents.

Usage

var random = require('mongoose-simple-random');

var s = new Schema({
  message: String
});
s.plugin(random);

Test = mongoose.model('Test', s);

// Find a single random document
Test.findOneRandom(function(err, result) {
  if (!err) {
    console.log(result); // 1 element
  }
});

// Find "limit" random documents (defaults to array of 1)
Test.findRandom({}, {}, {limit: 5}, function(err, results) {
  if (!err) {
    console.log(results); // 5 elements
  }
});

// Parameters match parameters for "find"
var filter = { genre: { $in: ['adventure', 'point-and-click'] } };
var fields = { name: 1, description: 0 };
var options = { skip: 10, limit: 10, populate: 'mySubDoc' };
Test.findRandom(filter, fields, options, function(err, results) {
  if (!err) {
    console.log(results); // 10 elements, name only, in genres "adventure" and "point-and-click"
  }
});
