ExtJS — How to load store data manually after ajax call? - extjs

Question

I rewrite my working Fiddle from ajax proxy type to memory. I'm trying to load memory store data manually:
// app/model/Employees.js file
Ext.define('Fiddle.model.Employees', {
extend: 'Ext.data.Model',
entityName: 'Employees',
fields: [
{
name: 'profile_pic'
},
{
type: 'int',
name: 'age'
},
{
type: 'string',
name: 'last',
mapping: 'name.last'
},
{
type: 'string',
name: 'first',
mapping: 'name.first'
},
{
type: 'string',
name: 'email'
}
],
proxy: {
type: 'memory',
reader: {
type: 'json',
rootProperty: 'items',
totalProperty: 'total',
successProperty: ''
}
}
});
// app/store/Employees.js file
Ext.define('Fiddle.store.Employees', {
extend: 'Ext.data.Store',
pageSize: 30, // items per page
alias: 'store.employees',
model: 'Fiddle.model.Employees',
});
//app.js fule - launch() function
var store = Ext.create('Fiddle.store.Employees');
console.log(store);
Ext.Ajax.request({
url: 'mates.json',
success: function(resp) {
var result = resp.responseText;
console.log(result);
// store.loadRawData(result);
store.loadData(result);
console.log(store);
console.log(store.getAt(0));
},
});
As result I have 3386 records in store, every symbol in my json file. And what I see in console as first record:
What I'm doing wrong?
And where I need to put proxy lines - in model or in store?

Answer 1

responseText is a string, which contains the serialized JSON data. You have to deserialize it into an object before you can use loadRawData to load the object through the model converters into the store:
var result = Ext.decode(resp.responseText);
store.loadRawData(result);
loadData and loadRawData differ in that loadData does not call the converters on the model. loadRawData is equivalent to what the ajax proxy does, loadData is not.

Answer 2

Did it in this way:
//in Grid panel js file
listeners: {
afterrender: function(grid, evt) {
var myStore = grid.getStore();
Ext.Ajax.request({
url: 'mates.json',
success: function(resp) {
var result = Ext.decode(resp.responseText);
myStore.getProxy().data = result;
myStore.load();
},
});
}
}
In store autoLoad: true must be disabled. This way of loading instead of store.loadRawData(result); shows the correct number of records in the pagingtoolbar.
