CSLA 7 DataPortals and Parent, child list clarification

[fundez]

I'm in the process of porting CSLA 5.5 code to CSLA 7.

I have a parent table with 2 child lists. Does this mean when fetching a record do I need tp pass 3 IDataPortals ParentPortal, Child1Portal and Child2Portal?

Thanks,

Mike

Mike, You should be able to use an include or fetch the data in your factory or DAL class. Something like PurchaseOrder Int Id List<PurchaseOrderLine> Lines; List<PurchaseOrderAddress> Addresses; Var query = _context.PurchaseOrders .Include(a=>a.PurchaseOrderLines) .Include(a=>a.PurchaseOrderAddresses) Where(a=>a.Id = requestedId); Var po = await query.ToListAsync(); In your CSLA class, you will map PurchaseOrder to cslaPurchaseOrder and then bind to that using your choice of UI controls Regards, Kevin From: ***@***.***> Sent: Tuesday, May 16, 2023 10:43 AM To: ***@***.***> Cc: ***@***.***> Subject: [MarimerLLC/csla] CSLA 7 DataPortals and Parent, child list clarification (Discussion #3339) I'm in the process of porting CSLA 5.5 code to CSLA 7.

Thanks for responding. Does the fetch, delete and update of the children need a dataportal passed to it?

Are they part of the parent or done separately. I do mine separately and don’t have a lot of parent child objects, so each needs a dataportal. If you’re using a traditional parent-child and Entity Framework, then you don’t need a dataportal for each operation as EF will take care of the work.
