Using {{ csrf_token }} throws exception (AttributeError: 'dict' object has no attribute 'META') if no render context

[jeffrey k eliasen]

Calling render() with no context on a template that uses {{ csrf_token }} results in an exception being thrown.

I believe the appropriate fix is to change:

if "CSRF_COOKIE" not in request.META:

to:

if not request or not request.META or "CSRF_COOKIE" not in request.META:

I am happy to create a PR for this issue once I know it is a desired fix.

From the ​CSRF docs:

In the corresponding view functions, ensure that RequestContext is used to render the response so that {% csrf_token %} will work properly.

The request is required in the context.

(If you're looking to render your template in a true non-request context, you can use RequestFactory to generate a placeholder and add 'csrf_token': 'NOTPROVIDED' to the context in order to short circuit the CSRF input rendering.)
