I ready the forum thread that has resulted in the DomainUpgradeMode.Legacy mode. Can I use TableMapping to map to one of the views generated by DO3 for read only access to the DO3 class data?. I have a number of persistent classes in a large DO3 database that I needed to use in a new module I am developing using DO4. This thread was imported from our support forum. The original discussion may contain more detailed answer. |
DO4 still doesn't support mapping for views, even in Legacy mode. Although it's a good idea to implement this ;) We'll think about adding this quickly. Concerning DO3 databases: as far as I can judge, now it must be possible to map new entities to them in Legacy mode: custom type discriminators are there, so this must work. On the other hand, I'd implement IModule providing values for these type discriminators automatically based on [doSysTypes] table content (or simply adding this info to definitions model). Summary:
