[hamdan k abu taima]

Hello ,

ex:

var list = new frappe.ui.Listing({

hide_refresh: true,

appframe: wrapper.appframe,

method: 'erpnext.home.page.activity.activity.get_feed',

parent: $(wrapper).find(".layout-main"),

render_row: function(row, data) {

new erpnext.ActivityFeed(row, data);

}

});

list.run();

also where can I learn more about frappe in advanced , the developer guide is not helping a lot now

Unfortunately this code is not documented. We will get to it, but might take sometime. You can learn by seeing code samples!

frappe.ui.Listing is a generic list object that manages permissions and paging.

1. whitelist your python function using @whitelist()

2. use $.ajax /api/method/yourmodule.balance.yourmethod

Excuse me cz I am very fresh into this , 

here is my js simple ajax call

$.ajax({

type: "POST",

url: "/api/method/userbalance.balance.balance",

dataType: "json"

}).done(function( msg ) {

    alert( "Data :" + msg );

  });

here is my python 

from __future__ import unicode_literals

import frappe

from frappe.utils import cint

@frappe.whitelist()

def cdr():

"""get feed"""

return "hello"

It fails to return hello ,

Notes ( browser ):

http://0.0.0.0:8000/api/method/userbalance.balance.balance

ImportError

ImportError: No module named userbalance.balance

S userbalance is there but it cant see it ,

I wanted to be sure if its only my new module , so I tried this :

http://0.0.0.0:8000/api/method/Home.activity.get_feed

but is also failed ,note : get_feed back is adjusted to not accept parameters for testings , and hard-coded limits variables .

ImportError: No module named Home.activity

Make sure you put the correct module path. It is

http://localhost:8000/api/method/erpnext.home.page.activity.activity.get_feed

There is an issue about showing the correct error message - fixing that.
