data association HasMany with no fields

[RenaudM]

Hello ,
i have a XML like this :

<items>
  <item>
<type>Concert</type>
 <artistes>
  <artiste>Bruce Springsteen</artiste>
  <artiste>Madonna</artiste>
  <artiste>Pink Floyd</artiste>
  </artistes>
<link>http://wwww.aaaaaaaaa.com</link>
  </item>
</items>

but I can't read the "artiste" field with a model without fields :

Ext.define('MyApp.model.artiste', {
    extend: 'Ext.data.Model',
    config: {
    }
}); 

Ext.define('MyApp.model.news', {
    extend: 'Ext.data.Model',
    uses: ['MyApp.model.artiste'],
    config: {
        idProperty: 'news',
        fields: [
                {name: 'type',type: 'string'},
                {name: 'link'}
        ],
        hasMany: {
                model: 'MyApp.model.artiste',
                autoLoad: true,
                name: 'artistes'}
        }
}); 

and I have this error :

[WARN][Ext.data.Operation#process] Unable to match the record that came back from the server.

How can I do that ? i tried with a memory proxy but without any success ...

Will you help me ?

I suppose you will need to add the "associationKey" property in the "hasMany" config.

http://docs.sencha.com/touch/2-0/#!/...associationKey

hasMany: {
    model: 'MyApp.model.artiste',
    autoLoad: true,
    name: 'artistes', /* This is going to be a store name. ex) record.artistesStore */
    associationKey: 'artistes', /* The name of the property in the data to read the association from */
}

Why do you have this?

idProperty: 'news',

Show us store definitions as well.

[RenaudM]

idProperty: 'news', 

it was a try ... I removed it .

here my store :

Ext.define('MyApp.store.NewsXmlStore', {
    extend: 'Ext.data.Store',
    requires: [
        'MyApp.model.news'
    ],
    config: {
        autoLoad: true,
        autoSync: true,
        model: 'MyApp.model.news',
        storeId: 'NewsXmlStore',
        proxy: {
            type: 'ajax',
            url: 'http://www.welovemusic.fr/testflux',
            reader: {
                type: 'xml',
                idProperty: 'NewsXmlReader',
                rootProperty: 'items',
                record: 'item'
            }
        }
    }
}); 

[bluehipy]

Don't play with idProperty if you don't really know what it is doing

reader: {
type: 'xml',
idProperty: 'NewsXmlReader',
rootProperty: 'items',
record: 'item'
}

Why did you set idProperty: 'NewsXmlReader' ?

[RenaudM]

ok , I understood the lesson : i removed all "idProperty" !
but it still not work

the full code :

Ext.define('MyApp.store.NewsXmlStore', {
    extend: 'Ext.data.Store',
    requires: [
        'MyApp.model.news'
    ],
    config: {
        autoLoad: true,
        autoSync: true,
        model: 'MyApp.model.news',
        storeId: 'NewsXmlStore',
        proxy: {
            type: 'ajax',
            url: 'http://www.welovemusic.fr/testflux',
            reader: {
                type: 'xml',
                rootProperty: 'items', 
               record: 'item'
            }
        }
    }
}); 

Ext.define('MyApp.model.news', {
    extend: 'Ext.data.Model',
    uses: [
        'MyApp.model.artiste'
    ],    config: {
        fields: [
            {
                name: 'type',
                type: 'string'
            },
            //here : a lot of fields ...
             {
                name: 'link'
            },
        ],
        hasMany: {
            associationKey: 'artistes',
            model: 'MyApp.model.artiste',
            autoLoad: true,
            name: 'artistes'
        }
    }
}); 

Ext.define('MyApp.model.artiste', {
    extend: 'Ext.data.Model',
    config: {
     }
}); 

and finally :

Ext.define('MyApp.view.MyList', {
    extend: 'Ext.dataview.List',
        config: {
            store: 'NewsXmlStore',
            itemTpl: [
                        '<div>{type}</div>',    // it's ok for that 
                        '<br />', 
                        '<tpl for="artistes">',    // nothing appears ...
                        '    <p>{artiste}</p>',
                        '</tpl>'
                ]
    }
});

Try to read here about models and association:

http://www.sencha.com/forum/showthread.php?220417-Using-Model-associations-with-two-proxied-Stores




Your association is not fully defined. Artistes record is artiste but there is no mention of that in your models

thank you for the advice and the link : the example is a little bit complex for me , but I'm trying to figure how to apply it on my problem .
