else:
    return(login)

Answer 1

Your view must return an HttpResponse object.

It does this for one branch of your if statement:

return render_to_response(...)

But not in the else branch.

return(login)

If login is a view function that returns an HttpResponse object, then you can change your return statement to

return login(request)

However, I suspect you want to redirect the user to your login page instead. In that case, change your code to:

from django.http import HttpResponseRedirect
return HttpResponseRedirect('/login/')

where /login/ is the url of your login page.

Answer 2

The last line of your view is return login (don't know why you're wrapping your returns in parentheses, it's unnecessary). But presumably login is a function, and you're not calling it. I expect you mean to do return login() or return login(request).
