No way of persist new collections

[Vancete]

Hi there,

I'm getting in troubles persisting collections. The first time I initialize de db it works correctly, but if I try to add new collections on subsequents initializations, it never get saved to files.

Any idea on this? The collections are marked with autoupdate.

Thanks in advance

Hi, could you describe your setup a bit ore detailed? Maybe show some code snippets? I just checked the latest version against one of my applications using persistence. It worked. Which persistence system are you using? Disk persisting? It would really help to have more details and code ;)

Sure, first time:

`let loki = {}

let adapter = new lfsa() loki.db = new lokijs('socks.db', { adapter : adapter, autoload: true, autoloadCallback : loki.databaseInitialize, autosave: true, persistenceMethod: 'adapter', autosaveInterval: 4000 })

loki.databaseInitialize = function() {

let users = loki.db.getCollection('users')

if (users === null) {
  loki.db.addCollection('users', { indices: ['user'], unique: ['user'], autoupdate: true })
}

}`

Then I add a new collection, it won't be saved ever. `let loki = {}

let adapter = new lfsa() loki.db = new lokijs('socks.db', { adapter : adapter, autoload: true, autoloadCallback : loki.databaseInitialize, autosave: true, persistenceMethod: 'adapter', autosaveInterval: 4000 })

loki.databaseInitialize = function() {

let users = loki.db.getCollection('users')
let roles = loki.db.getCollection('roles')

if (users === null) {
  loki.db.addCollection('users', { indices: ['user'], unique: ['user'], autoupdate: true })
}

if (roles === null) {
  loki.db.addCollection('roles', { indices: ['name'], unique: ['name'], autoupdate: true })
  roles = loki.db.getCollection('roles')
  roles.insert({ name: 'admin', description: 'Highest permission on the system', removable: false })
}

}`

I don't really find it in the documentation but I believe if you are using persistenceMethod: 'adapter' and adapter: adapter then you are responsible to provide the logic of saving your file in that given adapter. https://github.com/techfort/LokiJS/wiki/LokiJS-persistence-and-adapters. What happens if you use it without those two lines?

Sorry, didn't provided that part of code, but was this:

const lfsa = require('lokijs/src/loki-fs-structured-adapter.js') let adapter = new lfsa()
