我有这两个实体。
public class ApplicationUser : IdentityUser<int>
{
public int DepartmentId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string NationalCode { get; set; }
public DateTimeOffset DateCreated { get; set; } = DateTimeOffset.Now;
public DateTimeOffset DateModified { get; set; } = DateTimeOffset.Now;
public CorporateTitle CorporateTitle { get; set; }
public Department Department { get; set; }
public ICollection<ApplicationRole> Roles { get; set; } //* instead of IdetityUserRole
public class ApplicationRole : IdentityRole<int>
{
public string DisplayName { get; set; }
public string Description { get; set; }
public ICollection<ApplicationUser> Users { get; set; } //* instead of IdetityUserRole
}
我想自定义这两个实体，例如覆盖导航属性。
我不想将 IdentityUserRole 类用于这些类之间的多对多关系。
我应该如何在 Identity Core 中为这种类型的隐式多对多编写配置？
builder.Entity<ApplicationUser>()
.HasMany(appUser => appUser.Roles)
.WithMany(role => role.Users)
.UsingEntity<>(); // here I don't know how to config this relationship.
这是该场景的配置需求。 （跳过导航 EF Core 5）
builder.Entity<ApplicationUser>()
.HasMany(u => u.Roles)
.WithMany(r => r.Users)
.UsingEntity<IdentityUserRole<int>>
(au => au.HasOne<ApplicationRole>().WithMany(role => role.UserRoles).HasForeignKey(u=> u.RoleId),
au => au.HasOne<ApplicationUser>().WithMany(user => user.UserRoles).HasForeignKey(r=> r.UserId));
