Question

I’ve got a Backbone.js/Rails app and I’m trying to create a new object through Backbone model.save().

The server is returning a 302 moved, but checking the rails controller, the create object exists, and I can navigate to the index, so the routes are properly in place.

I’ve tried replacing the backbone.js with a regular jquery .ajax function, and both return the 302, as I originally thought the error was in backbone, but I think this is showing that the error is actually in rails.

The request payload/parameters is pretty simple

{"user_id":130,"message_text":"does this go 302","authenticity_token":"GxN8nPf5YwS2j2HhWZxWiKej3Y72Vb5IQZ98u5Nl2gs="}

The backbone save method is

          var user_message = new Myapp.Models.UserMessage({
                user_id: user.id,
                message_text: $('input[name="message"]',this.el).val()
          });

         user_message.save({
                success: function(response) {
                new Message({message: response.message});
            },
                error: function() {
                new Error({ message: "adding message" });
            }
       });

A “302” response has nothing to do with backbone, as you’ve noted. It looks like you have authorization / authentication code that is causing this.
