node.js - Sequelize bulk synchronization does nothing -

i'm unable sequelize.sync() work. calling sync() on each model definition works flawlessly calling sequelize instance appears nothing, if model manager had no registered models in it.

consider following:

function syncall() {     console.log('retrieving exported models...')     let models = require('./models')     for(var modelname in models) {         let model = models[modelname]         // define() wraps regular sequelize.define() call         // model.define().sync() works!         model.define()     }      console.log('all exported models have been defined! syncing database...')     sequelize.sync({         logging: true     }).then(function() {         // operation completes no command executed in db         console.log('database synchronization complete!')     }).catch(function(error) {         console.log("database synchronization error:\n\t${error}")     }) } 

just trying understand i'm missing, why bulk synchronization isn't working me?

afaik need models defined before calling sequelize.sync(), right?!

found problem. refer end of accepted answer...

this code sequelize example works fine me:

var sequelize = new sequelize(config.database, config.username, config.password, config); var db: = {};  var task = sequelize.define("task", {   title: sequelize.string }, {   classmethods: {     associate: function(models) {       task.belongsto(models.user, {         ondelete: "cascade",         foreignkey: {           allownull: false         }       });     }   } });  var user = sequelize.define("user", {   username: sequelize.string }, {   classmethods: {     associate: function(models) {       user.hasmany(models.task);     }   } });  db.user = user; db.task = task;  object.keys(db).foreach(function(modelname) {   if ("associate" in db[modelname]) {     db[modelname].associate(db);   } });  sequelize.sync().then(() => {   // code here }); 

models have been defined via "sequelize.define(...)" , after "sequelize.sync()" has been called.

update 1

i'm using sqlite:

var config: = {     "dialect": "sqlite",     "storage": "./db.development.sqlite" }; 

update op

i've spotted diference between code , mine. due bug in logic sequelize.define() , sequelize.sync() being called different sequelize instances (i.e different connections) , each connection has own modelmanager there no models sync in second connection object.
