Skip storing "Target"."Old" and "Environment" in the underlying store.

[buczkow]

Is there any way to narrow dataset stored in underlying store ?
Let's assume I would like to skip persisting bolded json:
{
"EventType": "Order:Update",
"Environment": {
"UserName": "Federico",
"MachineName": "HP",
"DomainName": "HP",
"CallingMethodName": "Audit.UnitTest.AuditTests.TestUpdate()",
"Exception": null,
"Culture": "en-GB"
},
"StartDate": "2016-08-23T11:33:14.653191-05:00",
"EndDate": "2016-08-23T11:33:23.1820786-05:00",
"Duration": 8529,
"Target": {
"Type": "Order",
"Old": {
"OrderId": "39dc0d86-d5fc-4d2e-b918-fb1a97710c99",
"Status": 2,
"OrderItems": [{
"Sku": "1002",
"Quantity": 3.0
}]
},
"New": {
"OrderId": "39dc0d86-d5fc-4d2e-b918-fb1a97710c99",
"Status": -1,
"OrderItems": null
}
}
}

One option is to set up a Custom Action to remove the data you don't need, for example:

Audit.Core.Configuration.AddOnSavingAction(scope =>
{
    scope.Event.Environment = null;
    if (scope.Event.Target?.Old != null)
    {
        scope.Event.Target.Old = null;
    }
});

If you are not using Target.Old, maybe it's better to just use a Custom Field, for example to create a field named "Order":

using var scope = AuditScope.Create("Event Type", null, new { Order = order });

or

using var scope = AuditScope.Create("Event Type", null);
scope.SetCustomField("Order", order);
