我正在Asp.Net MVC中构建一个简单的博客应用程序,并且我想使用Redis数据库。
我已经为我的Users类创建了一个存储库,其中包含一些方法(create,getbyid和update)。探针是 GetById(long id)方法。
using System;
using System.Collections.Generic;
using System.Text;
using ServiceStack.Redis;
using Domain.Entities;
using RedisDataLayer.AbstractRepository;
using System.Linq;
namespace RedisDataLayer.ConcreteRepository
{
public class UserRepository : IUserRepository
{
private readonly IRedisClient _redisClient;
public UserRepository(IRedisClient redisClient)
{
_redisClient = redisClient;
}
public User Create(User user)
{
var redisUsers = _redisClient.As<User>();
user.UserId = redisUsers.GetNextSequence();
redisUsers.Store(user);
return user;
}
public User GetById(long id)
{
var redisUsers = _redisClient.As<User>();
User returnUser;
returnUser = redisUsers.GetById(id);
return returnUser;
}
public User Update(User user)
{
var redisUsers = _redisClient.As<User>();
User savedUser = redisUsers.GetById(user.UserId);
savedUser.Username = user.Username;
savedUser.Password = user.Password;
savedUser.UserId = user.UserId;
foreach (var blogId in user.BlogIds)
{
savedUser.BlogIds.Add(blogId);
}
redisUsers.Store(savedUser);
return savedUser;
}
}
}
为什么此方法returnUser = redisUsers.GetById(id);
总是返回null?我一直在尝试在StackOverflow和其他地方找到答案,但是我找不到。
答案 0 :(得分:4)
.reloadAction(
"restartBenefits", "Ok. Let's start over.",
{
matches: /^start over$|^restart$/i
}
)
.cancelAction(
"cancelRequest", "Thank you for reaching out, Good bye!",
{
matches: /^nevermind$|^cancel$|^cancel.*request/i,
confirmPrompt: "This will cancel your request. Are you sure?"
}
);
API(以及所有其他ServiceStack.Redis类型客户端API)期望POCO在GetById()
属性中具有唯一的ID。
因此,您应该将用户模型更改为使用Id
而不是Id
。
