Django error: cannot import name current_datetime

Question

I'm Working through "The Django Book" and I keep getting the error "cannot import name current_datetime"

Urls.py:

from django.conf.urls.defaults import patterns, include, url
from mysite.views import current_datetime, hello

urlpatterns = patterns('', 
    ('^hello/$', hello), 
    ('^time/$', current_datetime),
    (r'^time/plus/(\d{1,2})/$', hours_ahead),
)

My Views.py:

from django.http import HttpResponse
import datetime

def hello(request):
    return HttpResponse("Hello world")

def current_datetime(request):
    now = datetime.datetime.now()
    html = "<html><body>It is now %s.</body></html>" % now
    return HttpResponse(html)

My working directory:

./mysite:
__init__.py manage.py   mysite      views.py

No matter what I do, I get the same import error in urls.py line 2, regarding current_time:

Environment:

just about to say the same thing, indentation is not correct — Glyn Jackson

Would you mind telling me what it should look like? I am copying it straight from djangobook.com/en/2.0/chapter03.html Thank you! — Jvieitez

What is mysite in the folder mysite? Is it also a folder? If so, does it contain __init__.py? — nymk
– nymk, Commented Apr 11, 2013 at 21:48
@nymk yes, I recently copied __init__.py to both folders per some other thread's suggestion. — Jvieitez

The outer mysite package was shadowed by the inner mysite. The mysite in from mysite.views import current_datetime, hello was resolved to the inner one. — nymk

Something is wrong with your working directory. manage.py and views.py should not be in the same directory. I would recommend renaming the inner mysite to something else, so you avoid the confusion, and views.py should be in the inner mysite directory. You said

from mysite.views import current_datetime, hello

but views.py isn't in the mysite directory. That's the problem.

Bam! Solved! That was the problem. Thanks so much! I was editing the views.py located in the outer mysite folder rather than the other mysite contained in that one. I will definitely have to rename them. Thank you!
