Problem using writeAllFields?

[bryan10]

I have set Data writer writeAllFields config to false for an
Update request (so that only modified form fields are sent to
server - but all fields are being sent.


The model is configured as below.


I then load a record into a form from a grid using:
loadRecord(sel.getSelection()[0]);


I then modify a field in the form.


I then use the following to retrieve the form record and send
update request to server:
var rec = this.up('form').getRecord();
rec.save({
success: function() { ... }
})


The request is sent but all fields are sent not just the modified
field?


Thank you in advance,
bryan



var newWriter = Ext.create('Ext.data.writer.Json',{
writeAllFields: false
})




Ext.define('BILL.model.Band', {
extend: 'Ext.data.Model',


fields: [
{name: 'id', type: 'long'},
{name: 'band', type: 'long'},
... // more fields
],


proxy: {
type: 'ajax',
api: {
update: '/updateband'
},
reader: {
type: 'json',
root: 'data',
successProperty: 'success',
messageProperty: 'msg'
},
writer: newWriter
},
belongsTo: '...'
});


request payload
{"id":669,"band":"3",...extra fields...}


response I send
{ success: true, data: [{"id":669}]}

Have you checked out the modified object on the record? Does it have all the fields in there or just the ones you expected to be modified?
