I'm building a simple blog application in Asp.Net MVC and I want to use a Redis database.
I have created a repository for my Users class that contains a few methods (create, getbyid and update). The probelm is the GetById(long id) method.
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;
}
}
}
Why does this method returnUser = redisUsers.GetById(id);
always return null? I've been trying to find an answer on StackOverflow and other places but I couldn't.
The GetById()
API (and all other ServiceStack.Redis Typed Client APIs) expect the POCOs to have a unique Id in an Id
property.
So you should change your User model to use Id
instead of UserId
.
