Just to make sure I understand this correctly, let me try to summarize
what this would mean:
* the proposed app controls {{ messages }} and is responsible for
retrieving anything set in the Message model
* old apps that call user.message_set.create will still get their
messages to the screen, assuming the project uses {{ messages }} in
the template
* old apps that call get_and_delete_messages or iterate through the
Message.objects.all() manually will NOT see any messages that were
stored in the session or a cookie, but they will continue to see
messages created the old way
* judging from your code, the new app will NOT store any messages in
the old Message model, it will only read them
* the standard template code:
{% if messages %}
<ul>
{% for message in messages %}
<li>{{ message }}</li>
{% endfor %}
</ul>
{% endif %}
will continue to work untouched after the update. For those that
choose to leverage it, a {{message.level}} (or otherwise named
attribute) will also be available.
* since we are tying ourselves to the {{ messages }} variable, this
probably means that the app should be called 'messages'. There has
been some hesitation about this. Are we in the clear now that we have
a potential upgrade path from the old API? Or is there still concern
about naming?
