Hey, I've got this problem. Whenever it comes to redirecting to detail function I get NoReverseMatch at /. Please help.

NoReverseMatch at /
Reverse for 'detail' with arguments '()' and keyword arguments '{'advice_id': 7}' not found.

You didn't call anything "detail" so it's not going to find it. Either add the name in your urls.py, use the full path to the function, or pass the function itself instead of a string.
