This model works in the shell. It holds messages and pops items off as
it iterates:
class MessageBox: # also tried with (models.Model)
def __init__(self, sort='neutral'):
self.sort = sort
self.messages = []
def __iter__(self):
return self
def next(self):
if len(self.messages) == 0:
raise StopIteration
return self.messages.pop()
I have this in my view to add a MessageBox object to the session and
then add a message to it:
if 'good_message_box' not in request.session:
request.session['good_message_box'] = MessageBox(sort='good')
request.session['good_message_box'].messages.append('MessageBox:
You have successfully logged in.')
I have this in my template to dispaly the messages:
{% if request.session.good_message_box %}
<ul class="errorlist">
{% for m in request.session.good_message_box %}
<li>{{ m }}</li>
{% endfor %}
</ul>
{% endif %}
However, unlike the shell behaviour which lists and deletes messages,
the template lists and retains the messages resulting in them
displaying repeatedly on every page (the template code is part of my
base template). Its as if my iterator is being ignored. I have tried
file based sessions and db based.
Am I missing something or can you not utilise objects in
request.session?
