View Full Version : Difference between Ext.data.HttpProxy and Ext.data.DirectProxy in post data

20 Apr 2010, 12:23 PM
I have a grid bound to a store very similar to the restful grid sample http://www.extjs.com/deploy/dev/examples/restful/restful.html

My DataStore is a Ext.data.DirectStore instead of a Ext.data.Store

When adding a new item to the grid, the post data sent to the server has a different format depending on the type of store used.

With Ext.data.Store -->

With Ext.data.DirectStore -->

Is this by design or a bug? If it's not a bug, can someone explain the reason for the different formatting

The funny part is that the 2nd data attribute comes from the reader root attribute and the first one seams to be a default root value....

I guess the difference comes form the type of proxy used, but I just can't nail this one.

Here is my code

var writer = new Ext.data.JsonWriter({
encode: false

var store = new Ext.data.DirectStore({
api: {
read: configuration_appconfig.getAppConfig,
create: configuration_appconfig.addConfig,
update: configuration_appconfig.updateConfig,
destroy: configuration_appconfig.removeConfig
autoLoad: true,
paramAsHash: true,
restful: true,
autoSave: true,
totalProperty: 'total',
successProperty: 'success',
idProperty: 'id',
fields: [
{ name: 'id' },
{ name: 'key', type: 'string', allowBlank: false },
{ name: 'value', type: 'string', allowBlank: true }
writer: writer

Any advice?
Thanks you for your help
