I am trying to set a custom header in my backbone.js application in a save method. The header isn't being set, even though I can set the header successfully in a fetch method.

switch(method){
    case 'read' :
        model.fetch({
             headers:{
                 "Override-Authorization":'Basic ' + proxyAuth
             }
        });
        break;
    case 'create' || 'update' :
        sendAuthentication = function (xhr) {
            xhr.setRequestHeader('Override-Authorization','Basic ' + proxyAuth);
        };
        model.save({
            beforeSend:sendAuthentication,
            headers:{
                "Override-Authorization":'Basic ' + proxyAuth
            }
       });
       break;
    case 'delete' :
        model.delete({
            headers:{
                "Override-Authorization":'Basic ' + proxyAuth
            }
        });
        break;
    }

In the first case, with fetch call, the header gets set properly. In the second case, with the save method, the header isn't set, even though I've tried it both ways. Any thoughts?

• javascript
• backbone.js

• 1 case 'create' || 'update' : doesn't do what you think it does. – mu is too short Commented Apr 18, 2013 at 16:00

You may want to have a look at the Model#save's doc.

model.save([attributes], [options]) 

You're actually setting some attributes to your model instead of overriding the headers.

model.save({}, {
  beforeSend:sendAuthentication,
  headers:{
    "Override-Authorization":'Basic ' + proxyAuth
  }
});

will do the trick.
