hello,
thanks for posting.
te way i do it is by creating a variable:
{% let email = company.contact.email %}
after that you can use email variable just like any other.
konstantin
class LetNode(Node) :
def __init__(self, var, expr) :
self.var, self.expr = var, expr
def render(self, context) :
try :
context[self.var] = resolve_variable(self.expr, context)
except VariableDoesNotExist :
context[self.var] = None
return ''
LET_TAG_RE = re.compile(r'^\s*let\s+(\w+)\s*=\s*(\S+)\s*$')
@register.tag
def let(parser, token) :
m = LET_TAG_RE.search(token.contents)
if not m :
raise TemplateSyntaxError, 'invalid syntax'
return LetNode(*m.groups())
