try in step 2:
action = ""
leave it blank, the form will be posted in the same view.
and in step 4:
<a href="/blog/category/{{ category.url }}/add_page/"> Add Page</a>
of course you have to insert url into the context dic this way in
views/category(): category.url = category_name_url.
I think your way the url will be processed as category//add_page/, the page
might not be found.
try the changes above and let me know if that works for you.
