what about:
try:
posts = Post.objects.get(Author=user)
# btw get will raise an AssertionError if more than record is found.
# i.e. if a user posted more than one post
except Record.DoesNotExist:
posts = None
return RequestContext(foo,bar, {'posts' : posts})
and in your template:
{%if posts %}
display the posts
{% else %}
No haven't posted anything
{% endif %}
