One View connected to multiple models

Question

I have the following problem…

MyView which is connected to two views: TaskModel and UserModel

TaskModel = {id: 1,          


        

Answer 1

jQuery's Deferreds work well here. As a crude example:

var succesFunction = function () {
    console.log('success');
};
var errorFunction = function () {
    console.log('error');
};

$.when(taskModel.fetch(), userModel.fetch()).then(successFunction, errorFunction);

You could also pipe the request through using the crude data (remember that fetch, save, create are really just wrappers around jQuery's $.ajax object.

var taskModelDeferred = taskModel.fetch();
var userModelDeferred = taskModelDeferred.pipe(function( data ) {
    return userModel.fetch({ data: { user: data.userId }});
});

note: Backbone returns the collection and model in the success / error functions by default on collections and models so if you need this be sure have a reference handy.
