Tutorial 1: AttributeError at /time/ 'module' object has no attribute 'now'
Nick Mellor
This must be very simple, but I'm stumped.
Here's the code for views.py
from django.http import HttpResponse
import datetime
def current_datetime(request):
now = datetime.datetime.now()
html = "<html><body>It is now %s.</body></html>" % now
return HttpResponse(html)
The offending line is:
now = datetime.datetime.now()
The code's cut and pasted from the Django 1.1 tutorial (http://
docs.djangoproject.com/en/1.1/topics/http/views/), and I have Django
1.1.1.
datetime.datetime.now() works as a function call at the Python shell:
>>> import datetime
>>> datetime.datetime.now()
datetime.datetime(2010, 2, 10, 5, 17, 21, 218000)
Any ideas? Thanks,
Nick

After:

I renamed the "now" variable as "dt" but it didn't help. I've also
tried your 1-tuple idea-- no change.
Note that the offending line isn't the html assignment but:
now = datetime.datetime.now()

Make sure your import line is correct.
In [1]: import datetime
In [2]: datetime.datetime.now()
Out[2]: datetime.datetime(2010, 2, 9, 14, 23, 25, 155503)

To clarify this, if you are doing:
from datetime import datetime
then you'd need to use datetime.now() instead of datetime.datetime.now().

It seems that whatever datetime is there in you view, it is not the datetime that is expected. You can put a breakpoint right before that line in you view and then investigate what is is you really have there. For example:
> /home/kmt/software/web/xword/crossword/views.py(39)main()
-> now = datetime.datetime.now()
(Pdb) datetime
<module 'datetime' from '/usr/lib/python2.5/lib-dynload/datetime.so'>
(Pdb)
Perhaps what you actually have for datetime will give a clue how datetime got to be something other than the standard datetime module.

the HttpResponse object, for testing purposes).
Be very sure that the spelling of everything in the file in question is correct
and that you aren't, for example, using the name "datetime" for something
else between the import and the usage.
If you're running in the development server, it is easy to stick in
pdb.set_trace()
(you'll have to import pdb) just before the offending line, and poke around when
you hit the breakpoint to see what datetime really is at that point.
If you don't hit the breakpoint, then you're not running with the file
you're editing.
Be sure that your really said "import datetime" rather than
"from datetime import datetime" (which is the way that I typically
import it) or that
someone else hasn't done that after your import.
If you're not running in the development server, then you might replace your
"now = ..." and "html = ..." lines with:
html = "<html><body>datetime is %r.</body></html>" % datetime
which will tell you what datetime is at that point. You will have to
restart apache
(or perhaps touch your .wsgi script file).
