django - Tiered shipping problem in Satchmo -

When I try to use the tiered shipping module in my store, I get the following error:

typeError at / shop / checkout / dummy / object .__ init (__) takes no parameters Request method: Request URL: http://127.0.0.1:8000/shop/checkout/ dummy / exception type: TypeError exception value: takes objection .__ init __ () is a parameter exception Area: /usr/local/lib/python2.6/dist- file "in __init__, line 28 Traceback ../ .. /apps/shipping/modules/tiered/models.py Packages / Django / Core / S Drivers / base.py "get_response 92. = callback (request in response, * callback_args, ** callback_kwargs) file" /usr/local/lib/python2.6/dist-packages/django/views/ decorators / cache.py pay_ship_info 10 return in payday "_wrapped_view_func 44 in response = view_func (request, * args, ** kwargs) file" ../../apps/payment/modules/dummy/views.py ".

I have also entered the carriers in the database.

Can anyone help me in this regard?

  super (on baseshipper, itself) .__ init __ (self)  < / Pre> 
 change it 
 
  super (BaseShipper, self) .__ init __ ()
