Using Jinja2 contextfunction like django inclusion tag -


i trying add contextfunction rendering menu html, jinja2 environment globals.

i have written:

@contextfunction def main_menu(context, parent, calling_page=none):     menuitems = parent.get_children().live().in_menu()     menuitem in menuitems:         menuitem.show_dropdown = has_menu_children(menuitem)         # don't directly check if calling_page none since template         # engine can pass empty string calling_page         # if variable passed calling_page not exist.         menuitem.active = (calling_page.path.startswith(menuitem.path)                            if calling_page else false)       return render ( context['request'], 'personal_web/tags/main_menu.html', { 'calling_page': calling_page,         'menuitems': menuitems,      })

but when use {{ main_menu( parent=site_root, calling_page=self) }} in template , call function renders ''

what doing wrong?
