CakePHP datatables server side processing problem

DudtheDood

Hi all,

I'm trying to make my datatables load faster by following the instruction here https://datatables.net/development/server-side/php_cake since I'm using CakePHP.

I have a property table and I copied function ajaxData() to my property controller and change the modelClass so it points to property.

Then I copied the getData() function to property model and edited $aColumns by putting my property columns and set the database connection.

But I'm getting error when I try to load the property index page with the table as shown in the following images.

Can anyone please help me with this?

Thanks a lot!
