object stereotypes and DataPortal

[Chicagoan2016]

Question Hi All, Is there any limitation on what Datportal methods can be called from a certain object stereotype? RoleEditManager.cs in ProjectTracker has called DataPortal.CreateChild(), DataPortal.FetchChild() and DataPortal.Execute()

Kind regards Version and Platform CSLA version: 4.7.100 OS: Windows Platform: WinForms, WPF, ASP.NET Core, MVC, Xamarin, etc.

No, as long as you understand the ramifications of each type of call.

• Create/Fetch/Update/Delete will all route to the logical server
• *Child will all run locally in the context of your current code

And you should create CriteriaObjects (parameters object to root DataPortal methods) derived from CriteriaBase<>

Also be aware that DataPortal.Execute() is special case of DataPortal.Update() over the wire.

Thank you @rockfordlhotka and @jonnybee

@jonnybee , I never thought about DataPortal.Update()--- client side. Since Save() takes care of Inserts and updates.

Also be aware that DataPortal.Execute() is special case of DataPortal.Update() over the wire.

I've been trying to understand why this statement invokes the update:

var obj3 = DataPortal.ExecuteAsync(obj2).Result;

BO [Csla.Server.ObjectFactory(typeof(SupplierFactory), "Create", "GetAsync", "UpdateAsync", "DeleteAsync", "ValidateAsync")] public async Task<SupplierInfoPersist> ValidateAsync(SupplierInfoPersist info) { var item = await DataPortal.ExecuteAsync(info); return item; }

FACTORY

 public object ValidateAsync(SupplierInfoPersist obj)
        {
            CheckRules(obj);
            return obj;
        }

I don't understand why the checkrules never gets executed, but the update fires. Any ideas?

I think part of the issue is getting the message out to the developers. I heard about CSLA through Brian Lagunas. Had he not mentioned it in passing, I would not have adopted it. But just as importantly, we need to get into StackOverFlow for questions and answers to problems. That is where a lot of developers go when asking questions. Additionally, it's my belief we need representation at developer conferences, classes online, and support or mentoring on CodeMentor would not hurt.
