[FIXED-583] nested xml / complex xml, cant get associations to work

Hi all,

There are users who can have books. so I came up with the following simple XML.

PHP Code:

---

<?xml version="1.0" encoding="ISO8859-1" ?>
<users>
  <user>
    <userid>1</userid>
    <username>Mickey Mouse</username>    
    <books>
      <book>
        <bookname>book a</bookname>
        <pages>723</pages>
        <score>55</score>
      </book>
      <book>
        <bookname>book b</bookname>
        <pages>434</pages>
        <score>86</score>
      </book>
      <book>
        <bookname>book c</bookname>
        <pages>123</pages>
        <score>37</score>
      </book>
    </books>    
  </user>
</users>

---

And the following method for loading the users and books in to the store and list:

PHP Code:

---


Ext.regModel('Book',{
      fields:[
      {name:'bookname',type:'string'},
      {name:'pages',type:'int'},
      {name:'score',type:'int'}
    ]
})

Ext.regModel('User',{
      fields:[
      {name:'userid',type: 'int'},
      {name:'username',type:'string'}      
    ],
    associations:[
      {type:'hasMany',model:'Book',name:'books'}
    ]
});

 

var HitrateStore = new Ext.data.Store({
    model: 'User',
    proxy: {
        type: 'ajax',
        url: './src/combi.xml',
        reader: {
            type: 'xml',
            record:'user'
        }
    },
    listeners: {      
        load: function(store, records, success){
          if(success)
          {
              if(debugMode)console.log('successfull loaded xml from server',records);
              console.log(HitrateStore)
          }
        }
    }
});
 

var testtpl = '<div class="graph">{username}</div>';

var list = new Ext.List({
    cls:'lijst',
    itemTpl:'<tpl for=".">'+ testtpl +'</tpl>',
    itemSelector: 'div.graph',
    singleSelect: false,
    grouped     : false,
    indexBar    : false,
    layout: 'card',    
    store: HitrateStore,
    floating     : true,
    width        : 350,
    height       : 370,
    centered     : true,
    modal        : true,
    hideOnMaskTap: false,
    listeners: {
                beforeactivate: function(c)
                {   
                  HitrateStore.load();
                }
              }
});

I dont get an error message. The users get loaded but their books dont get loaded....
Dont know where the problem is....

I also have updated to Sencha Touch 0.99....

Someone had the same problem or got an awnser?

Kind regards,

I'll see if I can get this replicated and fixed for the next release. Sorry for the inconvenience on this one - as demand is so low for XML-powered apps on mobile it has taken a back seat to JSON development

any news with this issue on 1.0RC..

Have you solved the association problem???

Moved this to the bugs forum and opened a ticket. This was lost in the conference mayhem last week - just as a heads-up that's less likely to happen if you report bugs in the bugs forum.

We're looking at putting out a 1.0.1 shortly so I'll try to get this in for then.

I've just added a patch to enable this to work. Currently, each Model is going to need an XML Reader to be able to parse the data properly. In your case you'll need something like this:

Code:

---

Ext.regModel('Book',{
    fields:[
        {name:'bookname',type:'string'},
        {name:'pages',type:'int'},
        {name:'score',type:'int'}
    ],
   
    proxy: {
        type: 'memory',
        reader: {
            type: 'xml',
            root: 'books',
            record: 'book'
        }
    }
});

Ext.regModel('User',{
    fields:[
        {name:'userid',type: 'int'},
        {name:'username',type:'string'}     
    ],
   
    hasMany: {model: 'Book', name: 'books'},
   
    proxy: {
        type: 'ajax',
        url : 'path/to/your.xml',
        reader: {
            type: 'xml',
            root: 'users',
            record: 'user'
        }
    }
});

If you're currently putting your initial Proxy on the Store instead (looks like you are), you can keep it there if you prefer. Note that you have to set a Proxy on the Book model to set up the Reader that will parse that nested XML. You need to make this a MemoryProxy for now as it will be passed associated data by the nested loading of the User model.

I'm not totally sold on this as an API but I have it tested and confirmed working. I'll revisit it later to see if we can make this a bit easier. These changes will be present in the next release.

Do you mean it already works or it will work as soon as the next release will be released?

Sir, I have made it as simple and as small as possible, i have read your data package blogs a lot of time, tried the above solution given by you, but this isn't working. Any kind of help would be great, my previous post was naive, but this I have written after reading your blogs. Please help me with this.
