Updating a field in a record dyanamically in extjs
- by Daemon
Scenario
I want to update the column data of particular record in grid having store with static data.
Here is my store:
:
:
extend : 'Ext.data.Store',
model : 'MyModel',
autoLoad:true,
proxy: {
type: 'ajax',
url:'app/data/data.json',
reader: {
type: 'json',
root: 'users'
}
},
My data.json
{
'users': [
{
QMgrStatus:"active",
QMgrName: 'R01QN00_LQYV',
ChannelStatus:'active',
ChannelName : 'LQYV.L.CLNT',
MxConn: 50
}
]
}
What I am doing to update the record :
var grid = Ext.getCmp('MyGrid');
var store = Ext.getStore('Mystore');
store.each(function(record,idx){
val = record.get('ChannelName');
if(val == "LQYV.L.CLNT"){
record.set('ChannelStatus','inactive');
record.commit();
}
});
console.log(store);
grid.getView().refresh();
MY PROBLEM
I am getting the record updated over here.It is not getting reflected in my grid panel.The grid is using the same old store(static).Is the problem of static data? Or am I missing something or going somewhere wrong? Please help me out with this issue.Thanks a lot.
MY EDIT
I am tryng to color code the column based on the status.But here I am always getting the status="active" even though I am updating the store.
What I am trying to do in my grid
{
xtype : 'grid',
itemId : 'InterfaceQueueGrid',
id :'MyGrid',
store : 'Mytore',
height : 216,
width : 600,
columns : [
{
text: 'QueueMgr Status',
dataIndex: 'QMgrStatus' ,
width:80
},
{ text: 'Queue Manager \n Name', dataIndex: 'QMgrName' , width: 138},
{
text: 'Channel Status',dataIndex: 'ChannelStatus' ,
width: 78,align:'center',
renderer: function(value, meta, record) {
var val = record.get('ChannelStatus');
console.log(val); // Here I am always getting status="active".
if (val == 'inactive') {
return '<img src="redIcon.png"/>';
}else if (val == 'active') {
return '<img src="greenIcon.png"/>';
}
}
},
{ text: 'Channel Name', align:'center', dataIndex: 'ChannelName', width: 80}
{ text: 'Max Connections', align:'center', dataIndex: 'MxConn', width: 80}
]
}
