Hi your best bet is to do the following - I used this for something
else but you'll get the idea:
from django.template import resolve_variable
from django import template
from django.template import Library, Node
register = template.Library()
class AlertNode(Node):
def __init__(self, request):
self.request = request
def render(self, context):
request = resolve_variable(self.request, context)
# Do something with the session
var = request.session.get('js_alert', None)
if var:
del request.session['js_alert']
return str('<script type="text/javascript">alert("%s");</
script>' % var)
else:
return ''
@register.tag(name="get_js_alert")
def get_js_alert(parser, token):
try:
tag_name, request = token.split_contents()
except ValueError:
raise template.TemplateSyntaxError, "%r tag requires exactly
one argument" % token.contents[0]
return AlertNode(request)
# Usage: {% load js_tag %}{% get_js_alert request %}
You now have acces to POST, GET and SESSION ect in your templatetag.
