django datetime.datetime error

Question

While following the tutorial here, I get down to where you run poll.was_published_today and I get this error:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/myDir/mySite/polls/models.py", line 11, in was_published_today
    return (self.pub_date() == datetime.date.today())
TypeError: 'datetime.datetime' object is not callable

Here is the code for my poll class:

from django.db import models
import datetime

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    def __unicode__(self):
        return self.question

    def was_published_today(self):
        return (self.pub_date() == datetime.date.today())

I've tried a few different things and it always chokes on any mention of "datetime".

This code:

import datetime
datetime.date.today()

when run in the interpreter works fine, just as expected, but in my file, it doesn't. Any suggestions?

@Ingacio: Doh! This is why I come here. So I don't spend even more hours working on a bug the first other set of eyes sees. While I did mess that up, it didn't fix it. It still produces the same traceback. — John

Typo. Should be

def was_published_today(self):
    return (self.pub_date.date() == datetime.date.today())

Yes I had messed that up, but that didn't fix it. It still produces the same traceback.

I don't understand. When I did the tutorial, I had the exact same code. I just tested it again and it still works. I guess, what Python version and what Django version are you using?

@Robert: Python 2.6.5 and Django 1.2.3.

@John - I'm stumped. I'm running those versions, with the same code (literally! I did the same tutorial last month), and have no problem.

@Robert: I just got it working. Really strange, it was(IS!) treating import datetime the same as from datetime import *.

I fixed it. For some reason it's treating import datetime like from datetime import * (Anyone know why?) So removing datetime from

return (self.pub_date.date() == datetime.date.today())

corrected it. I also decided to import datetime first though I don't know if that did anything.

The working file(for me) is:

import datetime
from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    def __unicode__(self):
        return self.question

        def was_published_today(self):
            return self.pub_date.date() == date.today()

I'm absolutely flabbergasted. I've NEVER seen Python do that. There's a reason the from syntax is so different - it's to avoid namespace pollution. You probably still have a problem, but I'm glad you've gotten it working.

@Robert: My thoughts exactly. Do you think I can ask a question why it's doing this or will it get closed as a dupe of this?

Robert Over a year ago

Eh... well it effectively is a dupe, now that we've figured out what it was... but you're well off the 'newest' list by now. Make sure to reference this question so you're upfront about it

@Robert: I asked it. Do you think I was clear enough? stackoverflow.com/questions/4468256/…
