int() argument must be a string or a number, not 'function' in django
messages

I am trying to use messages framework in my view, but its displaying the
following error
views.py
def gcontacts(request):
error = True
if request.method == 'POST':
if request.POST.has_key('wow'):
error = False
messages.add_message(request, messages.success, 'Wow key
exists !!!!')
else:
error = True
return render_to_response('key_exists.html', {'error':error},
context_instance=RequestContext(request))
error
