評論數據是怎么更新到數據庫的,我在DbInitializer類 Seed方法 加了數據 更新不到數據庫中
public static class DbInitializer
? ? {
? ? ? ? public static void Seed(AppDbContext context)
? ? ? ? {
? ? ? ? ? ? if (context.Noodles.Any())
? ? ? ? ? ? {
? ? ? ? ? ? ? ? return;
? ? ? ? ? ? }
? ? ? ? ? ? context.AddRange(
? ? ? ? ? ? ? ? new Noodle { Name = "毛細", Price = 12, ShortDescription = "如發絲般細", LongDescription = "如發絲般細如發絲般細", ImageURL = "" },
? ? ? ? ? ? ? ? new Noodle { Name = "細", Price = 10, ShortDescription = "普通細", LongDescription = "普通細普通細", ImageURL = "" },
? ? ? ? ? ? ? ? new Noodle { Name = "三細", Price = 11, ShortDescription = "有點粗了", LongDescription = "有點粗了有點粗了", ImageURL = "" }
? ? ? ? ? ? ? ? );
? ? ? ? ? ? context.AddRange(
? ? ? ? ? ? ? ? new Feedback { Name = "張三", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道香" },
? ? ? ? ? ? ? ? new Feedback { Name = "李四", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道很香" },
? ? ? ? ? ? ? ? new Feedback { Name = "王五", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道真香" },
? ? ? ? ? ? ? ? new Feedback { Name = "趙六", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道賊香" }
? ? ? ? ? ? ? ? );
? ? ? ? ? ? context.SaveChanges();//保存數據庫
? ? ? ? }
? ? }

//曉得怎么搞了
if (!context.Feedbacks.Any())
? ? ? ? ? ? {
? ? ? ? ? ? ? ? context.Feedbacks.AddRange(
? ? ? ? ? ? ? ? new Feedback { Name = "張三", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道香" },
? ? ? ? ? ? ? ? new Feedback { Name = "李四", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道很香" },
? ? ? ? ? ? ? ? new Feedback { Name = "王五", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道真香" },
? ? ? ? ? ? ? ? new Feedback { Name = "趙六", Email = "[email protected]", CreateDateUTC = DateTime.Now, Message = "味道賊香" }
? ? ? ? ? ? ? ?);
? ? ? ? ? ? ? ? context.SaveChanges();//保存數據庫;
? ? ? ? ? ? }
