Handling JSON message in store with many sub-association

Hello,

Here's my problem. I receive from the server a message of such shape

Code:

[{
    id: 2,
    description: "nicenice",
    idCustomer: 1,
    products: [{
        id: 3,
        name: "foo",
        description: "ff"
    },{id: 5,
        name: "foo2",
        description: "aaa"
    } 
    ]
    
},{
    id: 8,
    description: "ugly",
    idCustomer: 4,
    products: [{
        id: 4,
        name: "paa",
        dextion: "ghh"
    },{id: 6,
        name: "htht",
        description: "jj"
    } 
    ]
    
}]

and i would like to handle it in a store. So. Here's my problem.

I defined a model called product.

Code:

Ext.define('Myapp.model.ProductModel', {
    extend: 'Ext.data.Model',

    requires: [
        'Ext.data.Field'
    ],

    fields: [
        {
            name: 'id'
        },
        {
            name: 'name'
        },
        {
            name: 'description'
        }
    ]
});

then i defined a root model

Code:

Ext.define('Myapp.model.PlantModel', {
    extend: 'Ext.data.Model',

    requires: [
        'Ext.data.Field',
        'Ext.data.association.HasMany',
        'Myapp.model.ProductModel'
    ],
    uses: [
        'Myapp.model.ProductModel'
    ],

    fields: [
        {
            name: 'id'
        },
        {
            name: 'description'
        },
        {
            name: 'idCustomer'
        }
    ],

    hasMany: {
        associationKey: 'products',
        model: 'Myapp.model.ProductModel',
        foreignKey: 'id',
        name: 'products'
    }
});

Above i used "has Many", because i think it's correct to use, but actually i have no idea. I also put requires 'Myapp.model.ProductModel' because they say it's something to do (but i don't know why).

Then i defined a store and i set Plant as its model.

but it doesn't work. If i fetch the elements from the store, i just receive the first "part" of the model. I receive the "id", "description" and "idCustomer".

How could i retrieve the other part?

what am i missing?
