The template in your view is not a parameter, but is hard-coded into the call to render_to_response. Your code appears to be wanting to access the default value of a non-existent view parameter, modify it, and pass it back into a view that isn't expecting it.
It seems like you want to make `template` a parameter to the view, and then your middleware could modify that. -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.
