I have a satchmo site in development, and I'm getting the following
odd error when trying to add products to the cart:
File "/usr/lib/python2.5/site-packages/satchmo/shop/models.py", line
410, in _get_line_unitprice
price = self.qty_price + self.detail_price
TypeError: unsupported operand type(s) for +: 'Decimal' and 'Decimal'
It only occurs sometimes, and restarting Apache seems to fix the
problem. Does anyone have any ideas about this? I'm running Django 1,
Satcmo 0.8.1, Apache 2.2 on Ubuntu 8. Full traceback below:
