Question

我有这两个实体，PatientRegistry和PatientAccount。他们之间的关系是1-0..1。我正在尝试在我的主表PatientRegistry中播种，但我在可选表PatientAccount中的必填字段中仍然出现空错误。如何在主表中插入值而无需在我的主表中播种表也是？

未处理的异常：Microsoft.EntityFrameworkCore.DbUpdateException：更新条目时发生错误。查看内部异常详情。 ---＆GT; System.Data.SqlClient.SqlException：无法插入值为NULL的表'密码'，表 'ArtCoreDb.dbo.AspPatientsAccount';列不允许空值。更新失败。

public class PatientRegistry {
        [DatabaseGenerated (DatabaseGeneratedOption.Identity)]
        [Display (Name = "Record Id")]
        public long RecordId { get; set; }

        [Key, DatabaseGenerated (DatabaseGeneratedOption.None)]
        [Display (Name = "Patient File Number")]
        public long PatientFileId { get; set; }

        [Required, StringLength (50)]
        [Display (Name = "First Name")]
        public string FirstName { get; set; }
        public virtual ICollection<PartnerRegistry> Partners { get; set; }
        public virtual PatientAccount PatientAccount { get; set; }
}

public class PatientAccount {
        [Key, DatabaseGenerated (DatabaseGeneratedOption.Identity)]
        public long RecordId { get; set; }
        [Required]
        public string Password { get; set; }
        [Required, StringLength (15)]
        public string MobileNo { get; set; }
        public bool IsConfirmedPhoneNumber { get; set; } = false;
        public bool IsConfirmedEmailAddress { get; set; } = false;
        public bool IsLocked { get; set; } = false;
        public int? FailedAttempts { get; set; }
        public DateTimeOffset? LastLoggedIn { get; set; }
        public DateTimeOffset DateCreated { get; set; }
        [Timestamp]
        public byte[] RowVersion { get; set; }
        public long? PatientFileId { get; set; }
        public virtual PatientRegistry PatientFile { get; set; }
    }

我的流利API，

protected override void OnModelCreating (ModelBuilder builder) {
        base.OnModelCreating (builder);
        builder.Entity<PatientRegistry> ()
                .HasOne (a => a.PatientAccount)
                .WithOne (b => b.PatientFile)
                .HasForeignKey<PatientAccount> (c => c.PatientFileId)
                .OnDelete (DeleteBehavior.Cascade);

}

我种子，

if (!context.PatientsRegistry.Any ()) {

    context.PatientsRegistry.AddRange (
        new PatientRegistry {
            PatientFileId = 1111,
                FirstName = "John"
        }
    );
    context.SaveChanges ();

}

仅在我添加时才有效，

PatientAccount =
new PatientAccount {
    PatientFileId = 1111,
        CountryCodeId = context.Countries.Where (g => g.Name == "United States of America").SingleOrDefault ().Id,
        AreaCode = 424,
        Email = "aamaizar@gmail.com",
        MobileNo = "3244990",
        IsConfirmedEmailAddress = false,
        IsConfirmedPhoneNumber = false,
        IsLocked = false,
        Password = "213123",
},

实际上，我希望能够插入PatientsRegistry表而无需插入PatientAccount

Answer 1

使用Add（或AddRange）标记图表中所有可访问的实体处于添加状态，我只需在播种期间向我的对象添加PatientAccount道具

new PatientRegistry { PatientFileId = 1111, FirstName = "John", PatientAccount = {.......} }
