    Default Answered: generate random data for a store (MVC)

    Hey all,
    I'm trying to generate a random data set for a store but I'm having trouble. My generator function is undefined, I'm probably declaring it in the wrong place/way or calling it in the wrong way. Here is my code (for my store file).

    Code:
    Ext.define('TR.store.Trends', {
            extend: 'Ext.data.Store',
            model: 'TR.model.Trends',
            generateData : function(){
                    var data = [];
                    //logic to populate  data array missing, for now I am just
                    //pushing a single entry
                    data.push({
                            name: '2012-12-10',
                            number: 10,
                            percent: 8.7,
                    });
                    return data;
            },
            data:this.generateData(),
    });
    Any help on this is much appreciated

  2. At defining time of TR.store.Trends, 'this' is often window or some other object, not the store instance which will be existed only when you create an instance of the store. So this.generateData will often be undefined.
    Try to fix your code as below:
    Code:
    Ext.define('TR.store.Trends', {
        extend: 'Ext.data.Store',
        model: 'TR.model.Trends',
        generateData : function(){
            var data = [];
            //logic to populate  data array missing, for now I am just
            //pushing a single entry
            data.push({
                name: '2012-12-10',
                number: 10,
                percent: 8.7,
            });
            return data;
        },
        // data:this.generateData(),
        constructor: function(){
            this.data = this.generateData();
            this.callParent(arguments);
        }
    });
