Store, View, Controller - API Configuration

[adossaji]

Hi all,

I am having some trouble conceptualizing how to configure my REST api with my store, view, and controller.

How can I autoload a function from my controller to make an API call before my view is loaded, and then have the response be parsed and sent to my store? Is this best practice?

Thanks in advance!

Here is some of my code:

StatusController.js

/**
 * This class is the controller for the main view for the application. It is specified as
 * the "controller" of the Main view class.
 *
 * TODO - Replace this content of this view to suite the needs of your application.
 */
Ext.define('CPT.view.status.StatusController', {
    extend: 'Ext.app.ViewController',
    alias: 'controller.status',


    name: 'StatusController',

    // THIS FUNCTION NEEDS TO BE RAN BEFORE THE VIEW IS LOADED
    onLoad: function() {


        var sessionId = localStorage.getItem("SessionId");


        var sharedFn = CPT.app.getController('CPT.shared.Shared');


        sharedFn.rpc({
            url: 'user/session/',
            params: {
                email: '****',
                password: '****'
            },
            headers: {
                    'X-Application-Name' : 'CPT'
            }
        });


    }




});

TicketStatus.js

Ext.define('CPT.store.TicketStatus', {
    extend: 'Ext.data.Store',
    xtype: 'ticketstatus',


    alias: 'store.ticketstatus',


    fields: [
        'event_date', 'event_name', 'request', 'status', 'purpose_of_request', 'comp_requested', 'paid_requested', 'comp_approved', 'paid_approved', 'comp_approved', 'paid_approved', 'comp_fulfilled', 'paid_fulfilled', 'edit_cancel_resubmit'
    ],


    data: { items: [


    /*  DATA WILL NEED TO BE HERE*/


    ]},


    proxy: {
        type: 'memory',
        reader: {
            type: 'json',
            rootProperty: 'items'
        }
    }
});

Status.js

Ext.define('CPT.view.status.Status', {
    extend: 'Ext.panel.Panel',
    xtype: 'status',


    requires: [


        'CPT.view.status.TabPanel',
        'CPT.view.status.StatusController'
    ],


    height: 800,


    scrollable: true,


    layout: {
        type: 'fit'
    },


    dockedItems: [{
        dock: 'top',
        xtype: 'statustabpanel' //TicketList.js and other tabs are nested in this tab panel
    }]


});

TicketList.js

Ext.define('CPT.view.status.TicketList', {
    extend: 'Ext.grid.Panel',
    xtype: 'ticketlist',


    requires: [
        'CPT.store.TicketStatus'
    ],


    title: '',


    store: {
        type: 'ticketstatus'
    },


    columns: [
        { text: 'Event Date',  dataIndex: 'event_date' },
        { text: 'Event Name', dataIndex: 'event_name' },
        { text: 'Request # [Holder]', dataIndex: 'request' },
        { text: 'Status', dataIndex: 'status' },
        { text: 'Purpose Of Request', dataIndex: 'purpose_of_request' },
        { text: 'Comp Tix Requested', dataIndex: 'comp_requested' },
        { text: 'Paid Tix Requested', dataIndex: 'paid_requested' },
        { text: 'Comp Tix Approved', dataIndex: 'comp_approved' },
        { text: 'Paid Tix Approved', dataIndex: 'paid_approved' },
        { text: 'Comp Tix Fulfilled', dataIndex: 'comp_fulfilled' },
        { text: 'Paid Tix Fulfilled', dataIndex: 'paid_fulfilled' },
        { text: 'Edit/Cancel/Resubmit', dataIndex: 'edit_cancel_resubmit' }
    ],


    listeners: {
        select: 'onItemSelected'
    },






});

Hi--

You don't necessarily need to have the data ready *before* the view is created. For example, you could hook into an event like "render" on the view, and load the grid's store at this time. You could also add the autoLoad config in your store config of your grid, and this will load the store once the view is created.

Either way, though, the grid will render the data once the remote request completes.

Thanks!

I am more concerned with how to run the onLoad function in my controller that calls my API. Once I have the object with data in it, it will be queried and will populate the grid in my TicketList and ParkingList.

Going back to my first response, you could add a render event listener to your view, and have it call a handler method that lives in your view controller.

Thanks!
