Hi all
Martin Hsu suggested to make sure that this is included so I now have this in
settings.py
TEMPLATE_CONTEXT_PROCESSORS=
("django.core.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n")
Still {{ perms }} is empty or at least not displayed.

Here is the view:
def user(request):
''' Provides information on the currently logged in user. '''
message = ''
# This is an object that represents the currently logged-in user.
# If the user isn't logged in, this will instead be an AnonymousUser object
user = request.user
# How to tell if a user is logged in.
if request.user.is_authenticated():
# Do something for authenticated users.
debug = 'User is authenticated.'
else:
# Do something for anonymous users.
debug = 'User is not authenticated.'
return HttpResponseRedirect("/login/")
# now user is authenticated, and has name == request.user.username
message = '<br>This user '
if user.has_perm('lab.add_test'):
message = message + 'can add a lab test.<br>'
else:
message = message + 'cannot add any lab tests.<br>'
if user.is_authenticated():
permissions = user.get_all_permissions()
else:
permissions = ''
data = {'request': request,
'user': user,
# passing through permissions is just for testing.
# I should just use {{ perms }} in the template
'permissions': permissions,
'message': message,
'debug': debug,
}
return render_to_response('lab/user.html', data)
------------------------------------------------------------
Here is part of the template user.html
<p>Permissions:<br>
{% for permission in permissions %}
+ {{ permission }} <br>
{% endfor %}
</p>
perms={% if perms.lab %}
yes perms
{% else %}
no perms
{% endif %}
<p>{{ message }}</p>
-------------------------------------------------------------
And here is the output I get:
Permissions:
+ lab.change_test
+ lab.add_test
+ lab.add_experiment
+ lab.delete_experiment
+ lab.delete_test
+ lab.change_experiment
perms= no perms
This user can add a lab test.
I could create a dictionary in the view of all the permission things I'd need
in a
template and pass that in but the {{ perms }} seems like it is really what I
should
be using as it supposed to be automatically available from the request object.
