Extjs reading complex JSON data into store

Question

I have Json data something like this:

{

"Data":

    {
    "Columns":
    [
        {
            "Name":"Name",
            "Format":"string"
        },
        {
            "Name":"Age",
            "Format":"N2"
        }
    ],
    "Rows":
    [
        {"ExtensionData":{},"Cells":["Vikas", 23],"Emails":[{"ExtensionData": }, Email": [email protected]", "CellOrdinal":0}]},
        {"ExtensionData":{},"Cells":["Vikram", 27],"Emails":[{"ExtensionData":{},"Email":"[email protected]","CellOrdinal":0}]},     
    ]
    }
    "Grid Name":"Users"
    }
}
}

I need to bind this to my grid.

The "Columns" tag contains grid column names. "Rows" contain records of the grid. Also there are some data like Name of the grid which is fetched from the database. It's a slightly complicated structure.

How to get this data into a store? How should my model be?

I just want to mention that you also have a code button {} to format ;) — sra

Atlast after lot of trial and error got the model ready...

Ext.define('Data', {
    extend: 'Ext.data.Model',
    fields: [
            { type: 'string', name: 'Grid Name' }
        ],
    hasMany: [{ model: 'Column', name: 'Columns' },
              { model: 'Row', name: 'Rows' }]
});

Ext.define("Column", {
    extend: 'Ext.data.Model',
    fields: [
            { type: 'string', name: 'Name' },
            { type: 'string', name: 'Format' }
        ],
    belongsTo: 'Data'
});

Ext.define("Row", {
    extend: 'Ext.data.Model',
    fields: [
            { type: 'string', name: 'Cells' },
            { type: 'string', name: 'Emails' }
        ],
    belongsTo: 'Data'
});
