I want to use Single-Table Inheritance, but I got the following
problem:
I got two classes, ForumPost and ForumTopic. ForumTopic extends
ForumPost.
ForumPost looks like this:
[ActiveRecord("forum_posts",
DiscriminatorColumn = "post_type",
DiscriminatorType = "String",
DiscriminatorValue = "post", Lazy = true)]
[Serializable]
public class ForumPost : ActiveRecordBase<ForumPost>
{
...methods and properties
}
ForumPost looks like this:
[ActiveRecord(DiscriminatorValue = "topic", Proxy =
typeof(ForumTopic), Lazy = false)]
public class ForumTopic : ForumPost
{
...methods and properties
}
The problem is, When I Call ForumTopic.FindAll(), I get a Array of
ForumPost (ForumPost[]), not ForumTopic[]..
When I try to cast the ForumPost[] to ForumTopic[], it returns null.
However, the documentation says:
"Each class can have its own FindAll, DeleteAll, only affecting its
subset of records on the same table."
Any idea how to get a Array of ForumTopic back?
