Let's say that I have entity and mapping classes below, and to keep things
simple they are showing only one References/Has Many property, but imagine
they have large number of one-to-many, many-to-many relationships.
In example classes, does it mean that an implementation of a repository's
method that retrieve an Author object, for this purpose, let's call it
GetAuthorById(int
id) has to always retrieve all of author's books or can I dictate what I
retrieve from database. For example, sometimes I would like to omit
grabbing the list of Books if they are irrelevant. If I can do this, what
way would you suggest to go about it? Perhaps, turn off lazy loading and
create completely separate methods; or pass something like enum
AuthorDetails param and based on it dictate .Query<Author>() within
GetAuthorById(int
id), or something completely else?
Author.cs
public class Author{
public virtual int Id { get; set; }
public virtual string Name { get; set; }
public virtual IEnumerable<Book> Books { get; set; }}
Book.cs
public class Book{
public virtual int Id { get; set; }
public virtual string Name { get; set; }
public virtual Author Author { get; set; }}
AuthorMap.cs
public class AuthorMap : ClassMap<Author>{
public ClientMap()
{
Id(x => x.Id).Column("PKId");
Map(x => x.Name);
HasMany(x => x.Books).KeyColumn("AuthorId");
Table("Authors");
}}
BookMap.cs
public class BookMap : ClassMap<Book>{
public BookMap()
{
Id(x => x.Id).Column("PKId");
Map(x => x.Name);
References(x => x.Author).Column("AuthorId");
Table("Books");
}}
