How to use dojox/data/JsonRestStore with dojox/grid/LazyTreeGrid? - dojo

Question

I have now this code:
define([
"dojo/_base/declare",
"dojox/data/JsonRestStore",
"dojox/grid/LazyTreeGrid",
"dojox/grid/LazyTreeGridStoreModel"
], function(
declare,
JsonRestStore,
LazyTreeGrid,
LazyTreeGridStoreModel
) {
var layout = { ... },
store = new JsonRestStore({
target: "/api/items" // for example
limitParam: "limit",
offsetParam: "offset"
}),
model = new LazyTreeGridStoreModel({
serverStore: true,
store: store,
childrenAttrs: [ "children" ]
});
return declare("CustomTreeGrid", [ LazyTreeGrid ], {
treeModel: model,
structure: layout
});
});
My widget send thousand requests to target URL after startup and freeze my browser. How to fix wrong behavior and save compatibility with RESTful API?
Solution with QueryReadStore work, but not in my situation - Django REST Framework return page with API declaration on GET requests.
Server return data in JSON format:
{
"items": [ ] //Array of items
"identifier": "id",
"numRows": 12 // Total count of items
}
Also I change the server response for returning array. Response headers also contain key "Content-Range: 0-2/3" (for example) and it's not work for me.
Server response headers:
HTTP 200 OK
Allow: GET, POST, HEAD, OPTIONS
Content-Range: items 0-1/2
Content-Type: application/json
Vary: accept
Server response body:
[
{
"id": 1,
"children": false,
"name": "name1"
},
{
"id": 2,
"children": false,
"name": "name2"
}
]

It is pretty hard to make a jsfiddle out of it because you need the server part as well.
I found this implementation: https://github.com/jeremyg484/dojo-json-rest-store
It uses a combination of : dojo.store.Cache, dojo.store.JsonRest, dojo.store.Memory and dojo.data.ObjectStore
Maybe you can do something with it...
See how it is used :
myStore = dojo.store.Cache(dojo.store.JsonRest({target:"usstates/"}), dojo.store.Memory());
grid = new dojox.grid.DataGrid({store: dataStore = dojo.data.ObjectStore({objectStore: myStore})
