I've given up waiting and trying. I have a hack in the form of a
template tag:
{% if request.session.good_message_box %}
<ul class="errorlist">
{% for m in request.session.good_message_box %}
<li>{{ m }}</li>
{% endfor %}
</ul>
{% empty_messages "good_message_box" %} <<<<<<
{% endif %}
@register.tag()
def empty_messages(parser, token):
try:
# split_contents() knows not to split quoted strings.
tag_name, message_box = token.split_contents()
except ValueError:
raise template.TemplateSyntaxError, "%r tag requires a single
MessageBox name." % token.contents.split()[0]
if not (message_box[0] == message_box[-1] and message_box[0] in
('"', "'")):
raise template.TemplateSyntaxError, "%r tag's argument should
be in quotes" % tag_name
return EmptyMessagesNode(message_box[1:-1])
class EmptyMessagesNode(template.Node):
def __init__(self, message_box):
self.message_box = message_box
def render(self, context):
try:
s = SessionStore(context['request'].session.session_key)
if self.message_box in s.keys():
s[self.message_box].messages = []
s.save()
return ''
except template.VariableDoesNotExist:
return ''
Obviously I'd rather not ask my web server to do all this 3 times
(good, bad and neutral messages) for each page view.
If anyone knows anything about the problem I've outlined, or has a
better suggestion than my hack, please do post.
