Mongoose permalink
==================
Create automatically slug permalink in your mongoose models
Motivation
There is several plugins with very similar functionality. But I have these conditions:
* create permalink(slug) from existing keys of a document (one key or list of keys)
* check existance of permalink in one simple query (few plugins are selected all documents started with value of permalink or in worse case checked existence in multiple cycles)
* we can not override save method and catch duplicate error
* when permalink exists we add unique suffix (unique depending on time, machine and process for use in a distributed environment, relatively short compared to a mongoose's ObjectId (14 characters))
* permalink is always required, unique and indexed
Install
``
sh
npm install mongoose-permalink
`
Options
Plugin has several optional parameters:
* path - Name of key in a schema (default 'permalink')
* sources - List of keys of a document from which is the permalink computed (default 'name')
* operation
- GRAB_FIRST - will use first non blank value (default 'GRAB_FIRST')
- CONCAT - will concat all non blank values
* slug - additional options from plugin speakingurl
- separator - char that replace the whitespaces (default '-')
- truncate - trim to max length while not breaking any words (default 50)
- ...
Usage
`
js
var mongoose = require('mongoose');
var permalink = require('mongoose-permalink');
var userSchema = new Schema({
name : { type: String },
username : { type: String }
});
userSchema.plugin(permalink, {
sources: ['name', 'username']
});
var User = mongoose.model('User', userSchema);
var user = new User({
name: 'Zlatko'
});
user.save(function(err, user) {
console.log(user.permalink); // => zlatko
});
//if permalink already exists unique ID will be added
var user2 = new User({
name: 'Zlatko'
});
user2.save(function(err, user) {
console.log(user.permalink); // => zlatko-3bqk9my9buecut
});
