How to refactor Ext.Ajax.request to Ext.Model.save

Hi,

I have the following code:

Code:

---

assignModel: function(model, date, callback) {
  var credentials = Ext.getStore('credentialsStore').first();

  Ext.Ajax.request({
            url: MyApp.Save,
            params: {
                username: credentials.get('username'),
                password: "",
                token: credentials.get('token'),
                ApiKey: MyApp.apiKey,
                date: Ext.Date.format(date, 'Y-m-d'),
                modelId: model.get('id')
            },
            success: function () {
                Ext.callback(callback.success);
            },
            failure: function () {
                Ext.callback(callback.failure, null, ["Failed to assign model"]);
            }
        });
}

---

And I want to refactor this by using model.save, here's the model:

Code:

---

Ext.define('MyApp.Model', {    extend: 'Ext.data.Model',
    config: {
        idProperty: 'id',
        fields: [
            {
                name: 'id',
                mapping: 'Id',
                type: 'string'
            },
            {
                name: 'name',
                mapping: 'Name',
                type: 'string'
            }
        ],
        proxy: {
            type: 'rest',
            url : MyApp.Save,
            actionMethods: {
                create : 'POST',
                update : 'POST',
            }
        }
    }
});

---

When I do the first method, I get a clean POST-request with all the params.

When I do the model.save() method, I get an OPTION and a POST-request with the JSON-object somewhere in it.

How can I alter the save method from the model, so it sends the (username, password, token,...) parameters too? Why are there 2 requests being sent?

If you get an OPTIONS request first, that is the browser checking the server to see if it supports CORS.

I see. But the request is still being sent wrong, I sent a JSON-object now with model.save() but I need to send a request like the one in the picture.

Most importantly: I don't get the username, token, apiKey parameters which are necessary for the back-end-request.

This is what the server expects:

So what do I have to do for the model.save() to work like this?

when you do a model.save() are you passing in the params or have them as extraParams on the proxy?

I now have them as extraParams, however they get sent in the queryString. Here's how the model.save() request looks:

So they're not in the "Request Payload", and there's no "Form Data"-entry with the Model-parameters. It's just the JSON-object, and the server isn't expecting that.
