Problems with using custom data models for the AuditTrail module

created 7 years ago

[DevExpress Support Team: CLONED FROM T569076: How I found out using Oids in clustered index in XAF is a very bad idea]

This is exactly what I did (see image attached) and when I am in Application Designer I can see my classes only, but for some reasons, somewhere original classes still end up in the app and clash with my own classes (unless I use different table names in which case both original and my tables are created).

As for default, you should probably introduce default attribute, something like DbTypeDefault("expression") so default expressions would be divided from db type because current system does not allow configuring primary keys with default value because all foreign key will be defined with the same value. Separate default attribute could solve this issue.

Hello Mario,

I have attached a working sample and my test database for you to test. This database was initially created and used when standard AuditDataItemPersistent and AuditedObjectWeakReference classes were in use. After that, I added fully custom classes and changed app settings. Please look for the "//Dennis: " strings in this project so as not to miss any important change. I hope this helps.
