Easy to Use

Step 1 Model定义

[PrimaryKey("Id")]
public class Blog : ISoftDeleted
{
    //...
    public int Id { get; set; }
    public string Title { get; set; } = null!;
    public string Content { get; set; } = null!;
    public int AuthorId { get; set; }

    //请注意这里的IsDeleted默认必须是false!表示未删除
    public bool IsDeleted { get; set; } = false;
}

Step 2 继承SoftDeleteDbContext

public class TestDbContext : SoftDeleteDbContext
{
	public TestDbContext(DbContextOptions<TestDbContext> options)
		: base(options)
	{
	}
    //...
	public DbSet<Blog> Blogs { get; set; }

	protected override void OnModelCreating(ModelBuilder builder)
	{
		base.OnModelCreating(builder);
		//根据情况自定义表名
        //...
	}
}

step 2 注册DbContext

var serviceProvider = new ServiceCollection()
  .AddDbContext<TestDbContext>(options =>
  {
      //使用你的数据库引擎
      options.UseInMemoryDatabase("test");
  })
  .BuildServiceProvider();

step 3 注意事项

//1. 请使用 DbSet.Remove() 方法，不可使用批量删除方法:ExecuteDelete(),ExecuteDeleteAsync()

Enjoy !

//Delete 1 模拟软删除
var blog1 = db.Blogs.FirstOrDefault(x => x.Id == 1);
db.Remove(blog1!);
db.SaveChanges();

//Delete 3 模拟强制删除
var blog3 = db.Blogs.FirstOrDefault(x => x.Id == 3);
db.Remove(blog3!, true);
db.SaveChanges();
