owned-types

问题 I have a model with a class Address marked [Owned] and a hierarchy of people (person, customer or employee, then even more subtypes etc). There are addresses at different stages of this hierarchy and all of it ends up in one table as EF Core is limited to table per hierarchy. I expected all the attributes from address to appear multiple times in that person table (once per mention in any of the subtypes) however it doesn't appear at all! Instead i see FK for each of them and a separate

问题 I'm struggling creating a non-nullable/required Owned Type with Entity Framework Core. I'm using EF Core 3.0 against PostgreSQL database. My value object: public class PersonName { public PersonName(string name) { this.Name = name; } public string Name { get; set; } } My entity: public class Person { public int Id { get; set; } public virtual PersonName FullName { get; set; } } My entity configuration: public void Configure(EntityTypeBuilder<Person> builder) { builder.ToTable(nameof(Person));

问题 After this question I tried working with owned entity types but I'm stuck at the following scenario: public class User { [Key] public Guid UserId { get; set; } public ICollection<Listing> Listings { get; set; } public Image Avatar { get; set; } } public class Listing { [Key] public Guid ListingId { get; set; } public ICollection<Image> Photos { get; set; } } [Owned] public class Image { public long Size { get; set; } public string Height { get; set; } public string Width { get; set; } }

However, I'm currently a bit stuck with the following: I have three classes Customer which is an entity and two value objects ( CustomerStatus and inside of it value object ExpirationDate ) - like this: public class Customer : Entity { //... constructor, other properties and behavior omitted for the sake of
