How to create a join table using sequelize and sqlite? - join

Question

I am trying to establish a many-to-many relationship between tables in sqlite using sequelize.
I want to add records to a join table (assign tasks to a user) and retrieve data from that table. For some reason, this does not work. Here is my code:
var orm = new Sequelize('db_name', '', '', {
dialect: 'sqlite',
storage: path.join(__dirname, 'db_name')
});
var User = orm.define('User', {
username: {type: Sequelize.STRING, unique: true}
});
var Task = orm.define('Task', {
id: {type: Sequelize.STRING, unique: true},
taskName: Sequelize.STRING
});
Task.hasMany(User);
User.hasMany(Task);
Task.sync();
User.sync();
Having read documentation (http://sequelize.readthedocs.org/en/latest/api/associations/#hasmanytarget-options), I expect that a join table TasksUsers should be created. I also expect .addTask method do be available. Then in another file I have:
db.User.findOrCreate({where:{username: "fakeUser"}}); //this seems to work
//some code to populate "Tasks" table;
db.User.find({where: {username: "fakeUser"}}).
complete(function(err,user){
console.log("user", user); //the user is found
db.Task.find({where: {id: "some_value"}}).
complete(function(err, task) {
console.log("task", task); //the task is found, so it works up to this point
user.addTask(task). //this line does not work
complete(function(err, results){
console.log("posting error", err);
});
})
});
I get an error "Possibly unhandled SequelizeDatabaseError: Error: SQLITE_ERROR: no such table: TasksUsers". The user.getTasks() method (without any arguments in the parentheses) does not work for the same reason.
Another observation: for testing purposes, I added these lines of code after establishing hasMany relationships:
orm.query("SELECT name FROM sqlite_master WHERE type = 'table'").success(function (res) {
console.log("tables", res);
})
The result that I get is tables [ 'Tasks', 'Users' ]
The versions: sequelize 2.0.0-rc2, sqlite3 3.0.4. I would be very grateful for any help.
