Curious what would be the proper way to add a derived attribute to a model (ActiveRecord).
The order number for my order class is a combination of two fields that both exist in the database, being id and customername.
So e.g.
id = 100
customername = ‘ACME’
Order number then would be ‘ACME-100’
Since id and customer name are in the database I can use things as $order->id etc.
How can I create a getter/setter for the derived attribute ordernumber so I don’t need to concatenate the two fields time and time again? Instead I’d like to use $order->ordernumber which would do that for me.
I know that this is an old thread, but it pertains to a problem I’ve seen. When I create derived attributes in a CGridview as shown above, I cannot seem to filter based on this new derived attribute. I observe:
Typing a filter criteria into the filter textfield does nothing
If my derived attribute adds any characters (such as a hyphen), then this hyphen appears in the filter box.
So I am assuming that the inner workings of the filter mechanism are calling the getter behind the scenes, and somehow need to be adjusted to fix this. Has anyone done it before?
