[web2py] Re: NameError: name 'category' is not defined (reddit clone application)
The paging includes references to "category" except when viewing posts by
author, there is no category.
A quick fix would be to skip the paging when listing by author:
{{if request.function!='list_posts_by_author':}}
{{if page>0:}}
{{=A('previous', _class='btn', _href=URL(args=(category.name, page-1)))}}
{{pass}}
{{if len(rows)>=10:}}
{{=A('next', _class='btn', _href=URL(args=(category.name, page+1)))}}
{{pass}}
{{pass}}

Does the ticket show what it thinks is line 117? list_posts_by_votes() has
2 mentions of category, and it isn't obvious to me why either would result
in this error, but focusing on the exact line may help.
