mongoose-sluggable-behavior

This module aims to provide a concurrency safe, lightweight, and simple-to-use sluggable behavior to your Mongoose schemas in Node. Simply:

1) create your schema (without the slug field), and
2) get your model model with:

var db = mongoose.createConnection('localhost', 'models');
db.once('open', function() {
  var Model = sluggableBehavior('ModelName', schema, { fields: ['sluggable1', 'sluggable2', etc.  ]}).model(db);
});

This module provides a drop-in replacement for save that will catch a unique field error on save if the field is the document's slug. If the slug is a duplicate, the behavior will append a counting variable to the end. Subsequent duplicates will be saved as:

slug
slug-1
slug-2
slug-3
etc.

Install

npm install mongoose-sluggable-behavior

Example

var mongoose = require('mongoose'),
sluggableBehavior = require('mongoose-sluggable-behavior');

var routeSchema = new mongoose.Schema({
  name: String,
  location: String,
  partner: String
});
var sluggableSchema = sluggableBehavior('ClimbingRoute', routeSchema, {
  fields: [
    'name',
    'location'
  ]
});

var db = mongoose.createConnection('localhost', 'sluggabledemoseven');
db.once('open', function() {
  var ClimbingRoute = sluggableSchema.model(db);

  ClimbingRoute.once('index', function() {

    var routeOne = new ClimbingRoute({
      name: "High Exposure",
      location: "Gunks",
      partner: "Bob"
    });
    var routeTwo = new ClimbingRoute({
      location: "Gunks",
      name: "High Exposure",
      partner: "Dylan"
    });

    routeOne.save(function(err) {
      console.log("Route One: " + routeOne.slug + " with " + routeOne.partner);

      // Save route 2 after we know route 1 has been saved
      routeTwo.save(function(err) {
        console.log("Route Two: " + routeTwo.slug + " with " + routeTwo.partner);
      });
    });

    var routeThree = new ClimbingRoute({
      name: "High Exposure",
      location: "Gunks",
      partner: "Patrick"
    });
    var routeFour = new ClimbingRoute({
      location: "Gunks",
      name: "High Exposure",
      partner: "Stewart"
    });

    routeThree.save(function(err) {
      console.log("Route Three: " + routeThree.slug + " with " + routeThree.partner);
    });
    routeFour.save(function(err) {
      console.log("Route Four: " + routeFour.slug + " with " + routeFour.partner);
    });
  });

  // The only gaurantee is that once will be saved before two.

});
