annotate gpp/bulletins/models.py @ 145:71cb4208dc98
Tweak to #30, admin dashboard. Because of a bug in Django (9568), my dashboard appears on the login page. To get around this, pass in the user to the templatetag, so it can do a 'if user.is_staff' check. Also tweaked the HTML and CSS to show non-zero pending items in red. Shortened the pending item titles for readability.
