Hi Sudipta,
You can do this in one of 2 ways:
1. Add it to your settings file, like you have done. I would however write
: url = "%s/login" % settings.BASE_URL instead.
2. Add a context processor. You should in your settings.py add:
TEMPLATE_CONTEXT_PROCESSORS = (
"django.contrib.auth.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"django.core.context_processors.static",
"django.core.context_processors.tz",
"django.contrib.messages.context_processors.messages",
"django.core.context_processors.request",
"context_processors.baseurl",
)
That includes the normally added context processors (at least those that we
have in our project at the moment).
Regards,
Andréas
