实体框架 - 列表（MVC）
public class Author
{
[Key]
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public ICollection<Book> Books { get; set; } = new List<Book>();
};
public class Book
{
[Key]
public int Id { get; set; }
public string Name { get; set; }
public int AuthorId { get; set; }
public Author? author { get; set; }
};
我的代码与此类似，我可以在作者控制器列表中分配给作者。书籍还是仅用于关系的属性？
例如，
author.Books = await _context.Books.Where(b => b.AuthorId == Id).ToListAsync();
它是正确的代码还是创建未图表的属性？
public class Author
{
[Key]
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public ICollection<Book> Books { get; set; } = new List<Book>();
};
public class Book
{
[Key]
public int Id { get; set; }
public string Name { get; set; }
public int AuthorId { get; set; }
public Author? author { get; set; }
};
I have code similar to this, can I assign in author controller list of books to author.Books or it's property only for relation?
For example
author.Books = await _context.Books.Where(b => b.AuthorId == Id).ToListAsync();
It's correct code or create NotMapped property?
