Avoid Undefined Index in CakePHP

There might be various problems regarding to undefined index in CakePHP and there are many solutions to it and some links i went through to fix the problem are:

Newby: "Undefined index" error
Something on CakePHP Notice (8): Undefined Index
CakePHP: Rendering an undefined index

However these couldn't help solve my problem, being newbie in Cake and after going through these posts, it clicked me that i might be doing something silly mistake.

Actually i was displaying news in my default page where I declared the variable news in apps_controller as below:

function beforeRender(){
$this->loadModel('News');
$todayNews = $this->News->find('first', array( 'order' => array( 'News.updated' => 'DESC' ) ) );

$this-> set('news', $todayNews);

}

And in my news controller I was using below code to render my index page:

function admin_index()
{
$allNews = $this->News->find('all',
array(
'order' => array
( 'News.updated' => 'DESC' ) )
);

$this -> set('news',$allNews);
}

You can see both had "news" being set. So when i called my index page i was always getting

Notice (8): Undefined index: News [APP\views\news\admin_index.ctp, line 18]

This made me go round and round for an hour... finally found out ti was the same variable causing problem.

then I changed the variable in my app_controller to be


function beforeRender(){
$this->loadModel('News');
$todayNews = $this->News->find('first', array( 'order' => array( 'News.updated' => 'DESC' ) ) );

$this-> set('displaynews', $todayNews);

}
and called the same in my default layout page and all worked like a charm... hope this will help save you some time that might use creatively..... Enjoy coding.

Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on (Multi-Threaded Applicaiton)

I was stuck on this for hours where the event raised from the class wouldn' t write to my textbox in the presentation layer.

I googled but could not find any concrete solution to this but at last after going through various websites i figured out the easier way to solve this.

This article will help users to call the function in the class and raise an event within the class and catch the event in form and display whatever message raised to the text boxes in multi threaded application (VB.net)
Lets go step by step now:


1. I have a form with command button cmdTest and text box txtAction where I display my messages raised from the class.



Private Sub cmdTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdTest.Click
Dim robot As New RobotProcess_Ama(Nothing)
AddHandler robot.TaskProcessed, AddressOf ActionLog
WorkerThread = New Threading.Thread(AddressOf robot.CheckQueue)
WorkerThread.Start()
End Sub

Private Sub ActionLog(ByVal FunctName As String, ByVal aMessage As String)
System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = False
txtAction.Text = TimeString & "From: " & FunctName & ":" & aMessage
System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = True
End Sub

Here i disabled checkforIllegalcrossThreadcalls and re-enabled them after finishing.

2. Now my class RobotProcess_Ama contains function called checkqueue and raises the message.
Public Sub CheckQueue()
Try
RaiseEvent TaskProcessed("From Class", TimeString & ": Creating log file")
' Threading.Thread.Sleep(200)

Catch ex As Exception
Throw ex
End Try
End Sub
