Hello,
I'm creating a template tag that will will allow session variables stored as
strings or
dict in a view to be available in its template. The syntax is:
{% session_value [view_name] [session_variable] [arg] %}
But at the moment I don't know how I can get Django to stop throwing name
errors
on variables/class names that are available. In my code, kwargs,
NoReverseMatch are all available, but
Django keeps reporting name errors on them.
Here's the snippet of the code at
https://github.com/charyorde/session_value/blob/master/templatetags/tags.py
bits = token.split_contents()
if len(bits) < 2:
raise TemplateSyntaxError("'%s' takes at least one argument"
" (path to a view)" % bits[0])
view_name = bits[1]
session_variable = '' # or args - bits at session_variable
kwargs = None # bits as argument to session_variable
return SessionNode(view_name, session_variable, kwargs,
legacy_view_name=True)
session_value = register.tag(session_value)
class SessionNode(template.Node):
def __init__(self, view_name, session_variable, kwargs=None,
legacy_view_name=True): #session_variable is used as args
self.view_name = view_name
self.session_variable = session_variable
#self.args = args
if kwargs is not None:
self.kwargs = kwargs
if not legacy_view_name:
self.legacy_view_name = legacy_view_name
I will like to know what I'm doing wrong. How do I prevent these constant
name errors whenever the
template tag is registered?
Thanks
