Using of Assistance class?

[former_member194142]

Hello

I have created a WDA, wherein I created a assistance class.

In my MAIN view, I have a my_action_method, here am pulling the data from database, hence I wrote a FETCH_ORDERS method in the assistance class and I am calling this method from my_action_method, I specified assistance class's FETCH_ORDERS as INSTANCE method, pls. let me know is it OK of INSTANCE method or I should go with STATIC method in assistance class?

Thank you

Hi, what the visibility of the assistance class methods you created. For E.g : - Instance method with visibility as public, wd_assit->FETCH_ORDERS to get orders in your method. Thanks, Chaitanya.

Thank you

Hi,

Its fine to call an instance method of your assistance class from your action method and no need of static methods as you have wd_assist object created by the WDA framework.

You can access all methods ( instance public methods ) of your assistance class like 

WD_ASSIST->FETCH_ORDERS( ).

In your case, the static method call is not required.

To understand more about static methods & instance methods, please refer the below link

Hope this helps you.

Rama
