I have these entities:
public class BlogPost {
public virtual int Id { get; set; }
public virtual IList<Keyword> Keywords { get; set; }
public virtual IList<BlogComment> Comments { get; set; }
}
public class BlogComment {
public virtual int Id { get; set; }
public virtual BlogPost Post { get; set; }
}
public class Keyword {
public virtual int Id { get; set; }
public virtual IList<BlogPost> BlogPosts { get; set; }
}
I want to load a paged-list of BlogPost
s by their Keyword
s and comments-count. So I try this:
var entities = session.Query<BlogPost>()
.Where(t => t.Published)
.FetchMany(t => t.Keywords)
.OrderByDescending(t => t.UpdatedAt)
.Skip((pageNumber - 1) * pageSize).Take(pageSize)
.Select(t => new {
CommentsCount = t.Comments.Count(),
Post = t
})
.ToList();
But the folowing error occurs:
Specified method is not supported.
And when I remove .Skip((pageNumber - 1) * pageSize).Take(pageSize)
it works! e.g.
var entities = session.Query<BlogPost>()
.Where(t => t.Published)
.FetchMany(t => t.Keywords)
.OrderByDescending(t => t.UpdatedAt)
// remove the below line
//.Skip((pageNumber - 1) * pageSize).Take(pageSize)
.Select(t => new {
CommentsCount = t.Comments.Count(),
Post = t
})
.ToList();
Have you any idea please to take a number of rows by including Keyword
s? Thanks for any suggestion.
