Have added 10 item for testing pagination.
Edit view, ready to edit template.
no message
Finished pagination, but there is some bug on Bookmark edit feature.

Try to fix this.
The ajax issue is actually caused by bookmark data is invalid.

For one bookmark == one user with unique url.
But when create test data item, we create multiple bookmark with same url. According to our logic:
#Create or get bookmark
    bookmark, created = \
            Bookmark.objects.get_or_create(link=link, user=request.user)
