Your current error is because you have modify your code and placed the "return render(request .... " line under "if request.method == "POST" .
This wasn't the case in the first view.py code you posted.
That line of code must not be under the if statement but should be at same level of indentation with it.
By putting it under the if statement, it means that line is only applicable to the POST request which resulted in the error you are having.
The line I'm referring to is this:
return render(request, 'namev.html', {'form':form})

Thanks a lot, I believe I am close to the result. I did exactly what you instructed and another error appeared thus:ValueError at /namev/
The view pages.views.Namev_view didn't return an HttpResponse object. It returned None instead.
