TinyDal 1.0.0

TinyDal

TinyDal is a lightweight and minimal abstraction over ORMs. It provides a convenient abstraction over it.

Usage:

// for some use cases see also the tests project in the solution

private class MyEntity : MultiTenantEntity
{
	public override long TenantId { get; set; }

	public override bool IsDeleted { get; set; }

	[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
	public override long Id { get; set; }

	public string Name { get; set; }
}

private class MyEntityRepository : EFBaseRepository<MyEntity>
{
	public MyEntityRepository (long? tenantId, DbContext context) : base(tenantId, context)
	{

	}

	public void QueryRaw(string sql)		//custom raw query here if you want
	{
		base.ExecuteRaw(sql);
	}
}

private class MyDataContext : EFBaseDataContext
{
	private DbSet<MyEntity> MyEntities { get; set; }

	public MyEntityRepository MyEntityRepository { get; private set; }

	public MyDataContext(DbContextOptions options,
						 long? tenantId,
						 IsolationLevel isolationLevel = IsolationLevel.ReadCommitted)
		: base(options, tenantId, isolationLevel)
	{
		this.MyEntityRepository = new MyEntityRepository(tenantId, this);
	}

	protected override void OnModelCreating(ModelBuilder modelBuilder)
	{
		modelBuilder.Entity<MyEntity>().ToTable("MyEntities");
	}
}

//
// Main
//

private MyDataContext BuildDataContext(string connectionString)
{
	var optionsBuilder = new DbContextOptionsBuilder<MyDataContext>();
	optionsBuilder.UseSqlServer(connectionString);
	return new MyDataContext(optionsBuilder.Options, 1);
}

string connectionString = @"Server=(localdb)\dev;Database=TinyDalTestDb;Integrated security=True;";

using (var dataContext = this.BuildDataContext(connectionString))
{
	dataContext.MyEntityRepository.Insert(new MyEntity
	{
		//Id = 1,
		Name = "Name"
	});

	dataContext.Save();

	dataContext.Commit();
}
