Hi everybody,
i have some problem i just dont understand. I have a business model
(derived from django namespace):
class Business(models.Model):
business = models.ForeignKey("self", related_name="other_business")
name = models.CharField(max_length=50, unique=True)
...
objects = BusinessModelManager()
and:
class BusinessModelManager(models.Manager):
def user_can_access(self, user):
if user.is_superuser:
return super(BusinessModelManager, self).get_query_set()
else:
return super(BusinessModelManager,
self).get_query_set().filter( Q(business__groups=user.groups.all()) |
Q(business__users=user) )
Now when i go ahead into django shell and do:
from eiwomisa.business.models import Business
Business.objects.all()
it returns the expected output, the Business objects.
But, i have a templatetag:
class Business(Node):
def __init__(self, context, user):
self.context = context
self.user = template.Variable(user)
def render(self, context):
user = self.user.resolve(context)
business = Business.objects.all()
#context[self.context] = business
#context[self.context] = 'nd'
return ''
def get_business(parser, token):
bits = token.contents.split()
return Business(bits[2], bits[3])
register.tag('get_business', get_business)
Which should do the same, but it throws the following error:
-----------------------------

-------------------------
Hm, thats something thats completely out of my mind, i mean, its the
same call, but it cannot get executed? Why is that?
Greetings and thanks in Advance
