django - ExtJs 4 Add records to the grid from JSON -

i'm new extjs user, , have next problem. i'm trying load info extjs grid, serialized json on server (i utilize django serialize() method), i'm getting empty grid. problem seems in callback function, loads info grid, can't solve it.

here code:

controller-function

renderstudentlist:function(){ var ul = this.getstore('users'); ul.load({ scope :this, callback : function(records, operation, success){ for(i in records){ /* here, think, should code assigns values json grid records */ console.log(records[i].get('fields').name, records[i].get('fields').email); } } }); }

json-data, server

{success:true, "students":[{"pk": 1, "model": "poll.student", "fields": {"name": "bob", "email": "bob@mail.ua"}}, {"pk": 2, "model": "poll.student", "fields": {"name": "sam", "email": "sam@gmail.com"}}]}

my model

ext.define('am.model.user', { extend: 'ext.data.model', idproperty: 'pk', fields: [{ name:'pk', type:'integer' },{ name: 'fields', type: 'object' }] });

my store

ext.define('am.store.users', { extend: 'ext.data.store', model: 'am.model.user', // autoload: true, proxy: { type: 'ajax', api: { read: '/ex/' }, reader: { idproperty: 'pk', type: 'json', root: 'students', successproperty: 'success' } } });

thanks all!

i think json should if not wrong:

{success:true, "students":[{"pk": 1, "fields": {"name": "bob", "email": "bob@mail.ua"}}, {"pk": 2, "fields": {"name": "sam", "email": "sam@gmail.com"}}]}

this done in python this: after recieve json string: in json string;

actual_data = [d['students']['pk'], d['fields'] d in json] output = "{" output += "success: true" output += json.dumps(actual_data) output += "}" homecoming httpresponse(output)
