Okay, I've moved one step closer to a viable solution. I've managed to
remove these lines:
mapping.IgnoreProperty(x => x.EntityId);
mapping.IgnoreProperty(x => x.RequestedRevision);
mapping.IgnoreProperty(x => x.IsCurrent);
from the utility and made the equivalent logic in an
IAutomappingConfiguration object's "ShouldMap" method. The only thing
left in the utility and mapping overrides now is:
mapping.References(x => x.Current, "CurrentId");
mapping.HasMany(x => x.Revisions).KeyColumn("CurrentId");
mapping.ApplyFilter<LogicalDeleteFilter>();
Is there any way to do .References(), .HasMany() and .ApplyFilter() in
IAutomappingConfiguration or in a convention? I'm now 3 lines of code
away from being able to delete 30 mapping files! Please help me! :)
