LS4: DisplayNamingStrategy

Hi,

I created an implementation of the IDisplayNamingStrategy interface, created an instance of that implementation and assigend it to my LightSpeedContext instance.

I expected that the GetDisplayName(...) will be called during formating an validation error. But that didn't happened.
Did I get the concept wrong?

You got the concept right, so this sounds like a bug.  Can you provide us with a simple, minimal repro?  Thanks!

Hi Ivan,

here is the repro.

have a look at the Bootstrapper.TestDisplayNamingStrategy().

Your entity is not associated with your LightSpeedContext.  In order for LightSpeedContext settings, such as DisplayNamingStrategy, to take effect, you must load the entity into a unit of work.

Note also that unique validation requires a unit of work, since it must issue a database query.  The unique validation on Name will be skipped in your test code because there is no unit of work to provide a connection for the uniqueness query.

Thanks for the clarification.

This is not going to work for me properly.

The whole Context/UnitOfWork is abstracted behind my application services.

At the UI level I want to have basic entity valdiation (required properties, type and length checks), that fails fast without hitting the infrastructure layer. At the application and domain Layer I have the UOW and there is where I want to perform the more extended validations (for example the unique checks).

With the current solution I need to go through the whole stack to get the display names for simple required property checks.

Is it possible to get a global (static?) point (regardless of any Lightspeed Context) where I can set the strategy? May be you check first if there is a strategy associated at the current entity, if not check if there is a global strategy and use that?

Kind regards,
Sörnt
