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)

django json extjs proxy grid

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
