Ajax proxy fiddle doesn't load relative path simpsons.json file -- why not?

[Cobo-Pablo]

Fiddle example: https://fiddle.sencha.com/#view/editor&fiddle/2700

Creating the most simple of examples that I could conjure, I'm not seeing the reason why this fiddle won't load the relatively referenced Simpsons.json file.

• Code taken directly from the first fiddle of this doc page:
https://docs.sencha.com/extjs/6.5.1/...rid.Panel.html

• And then referring to the fiddle doc:
https://docs.sencha.com/extjs/6.5.1/...roxy.Ajax.html

Ext.create('Ext.data.Store', {
    storeId: 'simpsonsStore',
    fields: ['name', 'email', 'phone'],
    proxy: {
        type: 'ajax',
        url: 'Data/Simpsons.json',
        reader: 'json'
    }
    // • Moved following data into: Data/Simpsons.json
    // • converted data to valid json w/ double quotes
    // data: [{
    //     name: 'Lisa',
    //     email: '[email protected]',
    //     phone: '555-111-1224'
    // }, {
    //     name: 'Bart',
    //     email: '[email protected]',
    //     phone: '555-222-1234'
    // }, {
    //     name: 'Homer',
    //     email: '[email protected]',
    //     phone: '555-222-1244'
    // }, {
    //     name: 'Marge',
    //     email: '[email protected]',
    //     phone: '555-222-1254'
    // }]
});


Ext.create('Ext.grid.Panel', {
    title: 'Simpsons',
    store: Ext.data.StoreManager.lookup('simpsonsStore'),
    columns: [{
        text: 'Name',
        dataIndex: 'name'
    }, {
        text: 'Email',
        dataIndex: 'email',
        flex: 1
    }, {
        text: 'Phone',
        dataIndex: 'phone'
    }],
    height: 200,
    width: 400,
    renderTo: Ext.getBody()
});

Two reasons:

1) The path shouldn't have 'Data/' in it, that is just a tree node describing it's children just like Assets and Packages
2) You aren't telling your store to load. You can add autoLoad: true to your store to make it load when it's instantiated

BAM! That was quick.

I still don't understand how it knows to look in the Data directory for the json file. Is that something setup in the fiddle context?

[mitchellsimoens]

Yes, that is a fiddle thing. When fiddle 1 was around, it didn't make live network calls for anything so having them split made sense for the ajax requests and since there were over 50,000 fiddles and fiddle 2 can work in a fiddle 1 way (so it doesn't break old fiddles) it has to be kept separate. In a new fiddle, you can assume the Assets and Data are merged into one file system.

Thanks Mitchell!
