Thanks Waldemar, That explains it and I fell back on using 'native'
GAE. I'm still learning what to use from Django and when to use
'native' GAE.
A follow up question I have is how to add a nickname to the user
model. I've spent a lot of time searching/thinking/tinkering how to do
this and keep ending up with problems. What I really want to
accomplish is to have a nickname for a user available in all views/
templates. The user case is to enable folks to change their nickname
at will without changing their username/login creds(also it will be
possible to have multiple users with the same nickname which is fairly
important for my user base).
I have created a UserProfile, with back reference to user model and
can successfully use my_user = user.get_profile() and then access the
nickname via my_user.nickname. Works ok for use in views.
However, I want to be able to show the nickname when using queries w/
collections in templates as one can use request.user.username in views
and user.username in templates(i.e. user.nickname). I've looked at use
a custom context processor for this but wondering if that is the best/
most scalable/preferred method for doing so.
Ideally it would work such as:
{% for user in users %}
{{user.nickname}} {{user.email}} ***user.email,
user.username, etc. already work via django.auth
{% endfor %}
when using a query such as users = user.connections.filter('user =',
myself).
Any guidance, suggestions, recommendations is appreciated.
