When you try a postid that doesn't exist, the select with .first() will
return None rather than a Rows object, so the value of "post" that you
return to the view is None. I assume your view must do something like
post.title, but since post is None, that results in an AttributeError. To
avoid that, you should either make sure the controller redirects or raises
a 404 when the post doesn't exist (so it never gets to the view), or
include logic in the view to check whether post is None (i.e., {{if
post:}}) and don't show the post record in that case.
