ABP 软删除ISoftDelete

一、简介

　　ABP 的软删除是为了，在删除的时候，不是真正的删除数据，是为了保护数据。

二、具体实现

　　在 Core  层，我们需要这个实体去实现这个 ISoftDelete 接口。实现它的 public virtual bool IsDeleted { get; set; } 方法即可。

namespace xxx.xxx.xxxxx
{
    using Abp.Domain.Entities;

    /// <summary>
    /// 餐馆招聘 （Mg58Infos_RestaurantRecruitment) 实体
    /// </summary>
    public partial class RestaurantRecruitment : BasicInfo, ISoftDelete
    {
        public bool IsDeleted { get; set; }
    }
}

 也可以实现 IFullAudited 方法，这个方法全一些。这个接口本身就继承了 ISoftDelete 接口。

namespace xx.xxx.xxx
{
    using Abp.Domain.Entities.Auditing;
    using xx.xx.xx;
    using System;

    /// <summary>
    /// 餐馆招聘 （Mg58Infos_RestaurantRecruitment) 实体
    /// </summary>
    public partial class RestaurantRecruitment : BasicInfo, IFullAudited
    {
        public long? LastModifierUserId { get; set ; }
        public DateTime? LastModificationTime { get ;set ; }
        public long? DeleterUserId { get; set; }
        public DateTime? DeletionTime { get ; set ; }
        public bool IsDeleted { get; set; }
    }
}

  更改以后需要更新数据库就可以了。

三、获取以删除的数据

　　获取以删除的数据，我们需要用到如下的方法。加上这using 在查询的时间，系统会过滤掉对 isdeleted 这个字段的筛选，从而获取所有的数据。

namespace Bit.xx.xxxxxx
{
    using Abp.AutoMapper;
    using Abp.Domain.Repositories;
    using xx.xx.Mg58Infos;
    using xx.x;
    using x.x.Mg58Accounts.Dto;
    using System.Threading.Tasks;
    using Abp.Domain.Uow;

    /// <summary>
    /// 餐馆招聘绑定 服务
    /// </summary>
    public class RecruitmentBindUserAppService : AbpZeroTemplateAppServiceBase, IRecruitmentBindUserAppService
    {

        private readonly IRepository<RecruitmentBindUser, int> _recruitmentBindUserRepository;
        private readonly IRecruitmentBindUserManager _recruitmentBindUserManager;
        private readonly IRepository<RestaurantRecruitment, long> _restaurantRecruitmentRepository;
        private readonly IUnitOfWorkManager _unitOfWorkManager;

        public RecruitmentBindUserAppService(
        IUnitOfWorkManager unitOfWorkManager)
        {
            _unitOfWorkManager = unitOfWorkManager;
        }
        
        public async Task<RecruitmentBindUserEditDto> RecruitmentUserFilter(RecruitmentBindInfoFilterInput input)
        {
            using (_unitOfWorkManager.Current.DisableFilter(AbpDataFilters.SoftDelete))
            {

                //todo 此方法需要修改，获取发布的餐馆招聘数据将直接从单表获取
                var recruitmentBindUser = await _recruitmentBindUserRepository.GetAsync(input.Id.Value);

                //todo 修改消息是否已读
                var recruitmentInfo = _restaurantRecruitmentRepository.Get(recruitmentBindUser.RecruitmentId);
                
                var q = recruitmentBindUser.MapTo<RecruitmentBindUserEditDto>();
                return q;

            }
        }

        
    }
}
