Question

I wanted to create a 3 level dijit.Tree, like that:

-root
|
--level1
 |
 --level2

I thought it would be really simple since there’s a code snippet in this tutorial (example 1). But somehow I manage to fail.
This is my dojo code (variable names are in Polish, I hope it’s not a problem):

modelRaportow = new dijit.tree.ForestStoreModel({
    store: new dojo.data.ItemFileReadStore({
        url: "logika/getJSON/getStatusRaportow.php"
    }),
    query: {typ: 'galaz'},
    rootId: 'statusRaportuRoot',
    rootLabel: 'Status raportu',
    childrenAttrs: 'raporty'
});

drzewoRaportow = new dijit.Tree({
    openOnClick: true,
    model: modelRaportow,
    showRoot: true,
    persist: false
}, "target-status-raportow");

drzewoRaportow.startup();

This is my JSON returned by logika/getJSON/getStatusRaportow.php (again, names are in Polish):

{
    "identifier":"id",
    "label":"status",
    "items": [
        {"id":0,"status":"zaakceptowane","typ":"galaz"
            "raporty":[{"_reference":1},{"_reference":2},{"_reference":3}]},
                {"id":1,"data":"24-10-2011","wykonujacy":"cblajszczak","idKlienta":3,"status":"Raport0","typ":"lisc"},
                {"id":2,"data":"24-10-2011","wykonujacy":"cblajszczak","idKlienta":1,"status":"Raport1","typ":"lisc"},
                {"id":3,"data":"24-10-2011","wykonujacy":"cblajszczak","idKlienta":3,"status":"Raport2","typ":"lisc"},
        {"id":4,"status":"odrzucone","typ":"galaz"
            "raporty":[{"_reference":5},{"_reference":6},{"_reference":7}]},
                {"id":5,"data":"24-10-2011","wykonujacy":"cblajszczak","idKlienta":1,"status":"Raport3","typ":"lisc"},
                {"id":6,"data":"24-10-2011","wykonujacy":"cblajszczak","idKlienta":3,"status":"Raport4","typ":"lisc"},
                {"id":7,"data":"24-10-2011","wykonujacy":"cblajszczak","idKlienta":3,"status":"Raport5","typ":"lisc"}
]}

And finally, this is what I’m getting: img – root node and lvl 1 nodes returned by query, no child nodes.

The question is – where is my mistake? Can anyone see it?

Answer 1

I have a partial answer: by stepping through the code in a similar situation, I’ve discovered that it expects childrenAttrs to be an array, so it should be:

childrenAttrs: ['raporty']

but I still cannot get the third level to appear in my case.
