          Example::
  
              async def my_async_func():
                  obj1 = await objects.get(MyModel, id=1)
                  obj2 = await objects.get(MyModel, MyModel.id==1)
                  obj3 = await objects.get(MyModel.select().where(MyModel.id==1))
  
          All will return `MyModel` instance with `id = 1`
