Hello,
I am following this document to do it.
http://docs.nopcommerce.com/pages/viewpage.action?pageId=1442499
But I got stuck when I come to the controller. I did not get what to do with this
"Normally I would write tests for the following code and verify that model mapping is working correctly, but I'll skip unit testing to keep it simple.
In the appropriate methods ("Create", "Edit", or "PrepareSomeModel") add the code to set this property. In most case it's not required because it's automatically handled by AutoMapper in the .ToModel() method.
In the public method to save entity (usually: "Create" or "Edit" methods with [HttpPost] attribute)
// Edit View Model -> Data Model
category.SomeNewProperty = model.SomeNewProperty;"
And When I run the project, It give error.
