- make
authorisedUsers
a membervariable ofBlogQuery
and use a marker/flag to know ifByUser
andRemoveHidden
should do the Join - use
JoinAlias
example
AuthorisedUser authorisedUser;
bool authorisedUsersJoined;
public BlogQuery RemoveHidden()
{
if (!authorisedUsersJoined)
this.Left.JoinAlias(r => r.AuthorisedUsers, () => authorisedUser);
this.Where(() => !authorisedUser.IsHidden);
return this;
}
FetchUserDetails is mutual exclusive with the other two because filtering on an association prevents NH from initializing the association. You'll need to subquery with the filter and query the resulting Ids and initialize then.
/// Loads up details of all users who have permission
/// to view the private blog
public BlogQuery FetchUserDetails()
{
this.Query = QueryOver.Of<Blog>()
.WhereRestrictionOn(b => b.Id).IsIn(this.Query.Select(b => b.Id))
.Fetch(r => r.AuthorisedUsers).Eager
.ThenFetch(au => au.User).Eager;
return this;
}
