DirectStore and GridPanel -> I have to pay for the new version

[jujubilation]

Hello,

I spent a night try to fill a grid !
In 5 minutes, I 'm able to have this to the client side (thanks to the ext-direct-pack) :

{"type":"rpc","result":{"classified": {"status":null,"name":"a","updated_at":"2009-04-29T11:21:48Z","display_address":null,"abstract":"a","estate_id":"1","end_announcement":null,"contact":null,"id":1,"owner_id":"1","start_announcement":null,"created_at":"2009-04-29T11:21:48Z"}},"status":true,"errors":[],"message":"Classifieds#index","tid":2}

But impossible to fill the grid :

        var store = new Ext.data.DirectStore({
          directFn: Classifieds.direct, // this function work !
          paramsAsHash: false,
          root: '',
          idProperty: 'id',
          fields: ['id', 'name']
        });

        var userColumns =  [
          {header: 'name', width: 160, sortable: true, dataIndex: 'name'},
          {id: 'id', header: 'id', width: 160, sortable: true, dataIndex: 'id'}
        ];

        var userGrid = new Ext.grid.GridPanel({
          renderTo: 'user-grid',
          title: 'Users',
          autoScroll: true,
          height: 300,
          store: store,
          columns : userColumns
        });

        store.load();

I try all the examples, lots of threads and Google but impossible to find what's wrong.
Someone can help me with this ? Thanks a lot for your help.

1) Your root is empty.
2) The idProperty doesn't match anything your data has returned.
3) The id field you've specified don't match anything your data has returned.

Thanks a lot for your help. However I already test the grid with :

root: 'classified'

And in my data, there is and id field (not in first position).

The root isn't 'classified'. It's 'result.classified', which is a lot better to see if you format the JSON data:

{
    "type": "rpc",
    "result": {
        "classified": {
            "status": null,
            "name": "a",
            "updated_at": "2009-04-29T11:21:48Z",
            "display_address": null,
            "abstract": "a",
            "estate_id": "1",
            "end_announcement": null,
            "contact": null,
            "id": 1,
            "owner_id": "1",
            "start_announcement": null,
            "created_at": "2009-04-29T11:21:48Z"
        }
    },
    "status": true,
    "errors": [],
    "message": "Classifieds#index",
    "tid": 2
}

Thanks Condor. sorry for this huge mistake. I changed the root but the result is the same : the grid is empty.
My code :

 var store = new Ext.data.DirectStore({
          directFn: Classifieds.direct,
          paramsAsHash: false,
          root: 'result.classified',
          fields: ['name']
        });

        var userColumns =  [
          {header: 'name', width: 160, sortable: true, dataIndex: 'name'},
        ];

        var userGrid = new Ext.grid.GridPanel({
          renderTo: 'user-grid',
          title: 'Users',
          autoScroll: true,
          height: 300,
          store: store,
          columns : userColumns
        });

        store.load();

Which Ext version are you using? For older Ext versions the root needs to be an array, e.g.

{
    "type": "rpc",
    "result": {
        "classified": [{
            "status": null,
            "name": "a",
            "updated_at": "2009-04-29T11:21:48Z",
            "display_address": null,
            "abstract": "a",
            "estate_id": "1",
            "end_announcement": null,
            "contact": null,
            "id": 1,
            "owner_id": "1",
            "start_announcement": null,
            "created_at": "2009-04-29T11:21:48Z"
        }]
    },
    "status": true,
    "errors": [],
    "message": "Classifieds#index",
    "tid": 2
}

I'm using the latest version (3.0).

[Condor]

3.0 isn't a version. The latest version is 3.0.1 and I assume you are using 3.0.0?

[jujubilation]

Yes, 3.0.0

[Condor]

In that case you'll need to convert your JSON data into an array (or upgrade to 3.0.1).
