我正在尝试将视图添加为实体的导航属性。
public class Schedule
{
public int Id { get; set; }
public decimal ScheduledQuantity { get; set; }
public ScheduleDetails ScheduleDetails { get; set; }
}
public class ScheduleDetails
{
public int ScheduleId { get; set; }
public decimal BadQuantity { get; set; }
public Schedule Schedule { get; set; }
}
带映射:
public class ScheduleDetailMap : IEntityTypeConfiguration<ScheduleDetails>
{
public void Configure(EntityTypeBuilder<ScheduleDetails> builder)
{
builder.ToView("vwScheduleDetails", "ShopOrders");
builder.HasKey(t => t.ScheduleId);
builder.HasOne(p => p.Schedule).WithOne(s => s.ScheduleDetails);
}
}
public class ScheduleMap : IEntityTypeConfiguration<Schedule>
{
public void Configure(EntityTypeBuilder<Schedule> builder)
{
builder.ToTable("Schedules");
builder.HasKey(t => t.Id);
builder.Property(t => t.Id).UseIdentityColumn();
}
}
当我查询它工作正常。但是,如果我添加一个新的计划记录。
var schedule = new Schedule
{
ScheduledQuantity = 100,
ScheduleDetails = new ScheduleDetails()
};
context.Schedules.Add(schedule);
context.SaveChanges();
我收到一个异常说“实体类型'ScheduleDetails'未映射到表,因此实体无法持久保存到数据库。使用'OnModelCreating'中的'ToTable'来映射它。”
无论如何让EF忽略保存这个“实体”?
