I find we can specify the "default-cascade" attribute of the element. But how can I do it in Fluent NHibernate? And I don't want to use AutoMapping.
The detailed description could be found here: https://github.com/jagregory/fluent-nhibernate/wiki/Conventions. An extract:
There are some situations that are so obvious that they just cried out for a simple shortcut that can be applied globally to your project:
Table.Is(x => x.EntityType.Name + "Table")
...
DefaultCascade.All()
...
And this way we can use it:
Fluently.Configure()
.Database(/* database config */)
.Mappings(m =>
{
m.FluentMappings
.AddFromAssemblyOf<Entity>()
.Conventions.Add(DefaultCascade.All());
})
