Hi guys :o)
Im attempting to create a template tag but I get a strange response.
it returns "None" where I put the {% if blog_detail %} tag
Here is my template tag
class BlogNode(Node):
def __init__(self, user, varname):
self.user, self.varname = user, varname
def render(self, context):
try:
context[self.varname] = Blog.objects.get(user=self.user)
except ObjectDoesNotExist:
context[self.varname] = False
@register.tag
def get_blog(parser, token):
# {% get_blog for user_object as object_detail %}
# {% if blog_detail %} etc...
bits = token.contents.split()
if len(bits) != 5:
raise TemplateSyntaxError, "get_blog tag takes exactly five
arguments"
if bits[1] != 'for':
raise TemplateSyntaxError, "second argument to get_blog tag
must be
'for'"
if bits[3] != 'as':
raise TemplateSyntaxError, "third argument to get_blog tag must
be
'as'"
return BlogNode(bits[2], bits[4])
Why does it response with a "None" message?
Thanks :o)
