Extjs Tree Store auto sync with server

[charles.bourasseau]

Hi,

how to use store to sync with server when using a Tree ?

I tried to use TreeStore (http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.TreeStore) but it does not have any appendChild oder addChild.
NodeInterface (http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.NodeInterface) has a appendChild method but it does not sync with the server trough the store or proxy...

Any ideas ?

1. You add records into TreeStore through its nodes. The following example shows how to add a node into root node.


treestore.getRootNode().appendChild({text: 'node', leaf: true....});


2. To sync TreeStore to with server, you use treestore.sync() or set its autoSync to true to automatically sync.

It works actually very well.

I just have a problem because the autoSync does not work even though it's set to true...



var store = Ext.getStore('MyStore');
store.getNodeById(id).remove(); // No Ajax here
store.sync(); // Ajax..


I also tried destroy(), but it produces an error and I can't figure out which line produces it:


TypeError: Cannot call method 'indexOf' of undefined

Below is my fix in removing a node.


var store = Ext.getStore('MyStore');
// store.getNodeById(id).remove(); // No Ajax here
var node = store.getNodeById(id);
node.parentNode.removeChild(node);
store.sync(); // Ajax..

I works, but it's not autoSync :(

I would like to have autoSync

Which version do you use? TreeStore.autoSync has effect only from Ext 4.1.

Hi, I used 4.0.7. I just try 4.1 and it works well.

I'm using a Rest Proxy, but I think it's not 100% rest.

The GET Request looks like Ajax one, it has Query String parameter, I thought the node would be in the url and not as Query. And for POST I would expect something like:
http://<url>/<Parent Resource ID> but it's only http://<url>.

Here are the POST, GET, DELETE Request:
