Tips for transferring information from the client in backbone.js to the server using Express and Backbone.js

I'm currently working on passing data from the client to the server using Backbone.js's save() method.

task_manager.js

window.Task = Backbone.Model.extend({
        initialize:function(){
        },
        urlRoot:"http://localhost:3000/api/tasks",
        defaults:{
            task:"",
            completed:false,
            category:"",
            priority:""
        },
        toggleCompletion:function(){
            this.destroy();
        }

});

server.js(Node/Express)

app.post("/api/tasks",function(req,res){
        console.log(req.task); // I am expecting to receive the task item's title of a newly created item, but req.title is undefined.

});

app_view.js(Backbone.js) implementation is shown below...

... 


 // The create method is supposed to create a new task item and send it to the server. However, it is not working as expected.


create:function(e){

var input = $(this.el).find("#new-task");
 if (e.keyCode !== 13) return;
   var text = input.val();
   var task = new Task({task:text});
    // This should send a POST request to "/api/tasks"
   task.save({task:text,body:"hello world"});
   var taskView = new TaskView({model: task});
    $("#task-item").append(taskView.render().$el);
                        $(input).val("");
                        this.collection.add(task);
                    }
        });

This code snippet is failing to pass data from the client to the server. Do you have any suggestions or ideas? Thanks in advance.

Your model information is not directly accessible via the request object in Express (req.title).

If you have set up express to utilize the bodyParser() for parsing HTTP POST Bodies

app.use(express.bodyParser());

Then your Backbone model will be found in request.data:

app.post("/api/todos",function(req,res){
        console.log(req.body.title);

});
