Writing your first Django app, part 1 - Django 1.7 - # Make sure our __str__() addition worked.

[Gavin Patrick McCoy]

Hi,

Just started learning Django today. I got down to the last grey box of code 
on 
https://docs.djangoproject.com/en/1.7/intro/tutorial01/#writing-your-first-django-app-part-1
 and 
when I checked to see of the __str__() addition to models.py worked, it 
didn't. I didn't get [], I got []. I tried creating a new question again and did but now I get  
[, ]. I then tried 'the 
three-step guide to making model changes: Change your models (in models.py). 
Run python manage.py makemigrations 

 
to create migrations for those changes. Run python manage.py migrate 
 
to apply those changes to the database.' I still got  [, ]. Any ideas? Any help would be greatly 
appreciated. 

Thanks, Gavin

My models.py looks like this: 

import datetime
from django.db import models
from django.utils import timezone
# Create your models here.
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')

def _str_(self):
return self.question_text

def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

class Choice(models.Model):
question = models.ForeignKey(Question)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
def __str(self):
return self.choice_text

Writing your first Django app, part 5 Testing

[Gavin Patrick McCoy]

Hi, 

I'm on part 5 of the polls tutorial 
(https://docs.djangoproject.com/en/1.7/intro/tutorial05/) and I am running 
Django 1.7 and Python 3.4 on Windows 8. Just want to make sure I'm on the 
right track.

For the following part of tutorial:

>>> # get a response from '/'>>> response = client.get('/')>>> # we should 
>>> expect a 404 from that address>>> response.status_code404>>> # on the other 
>>> hand we should expect to find something at '/polls/'>>> # we'll use 
>>> 'reverse()' rather than a hardcoded URL>>> from django.core.urlresolvers 
>>> import reverse>>> response = client.get(reverse('polls:index'))>>> 
>>> response.status_code200>>> response.content'\n\n\nNo polls are 
>>> available.\n\n' *<-Not getting this. See below. Seeing What's 
>>> up?*>>> # note - you might get unexpected results if your ``TIME_ZONE``>>> 
>>> # in ``settings.py`` is not correct. If you need to change it,>>> # you 
>>> will also need to restart your shell session>>> from polls.models import 
>>> Question>>> from django.utils import timezone>>> # create a Question and 
>>> save it>>> q = Question(question_text="Who is your favorite Beatle?", 
>>> pub_date=timezone.now())>>> q.save()>>> # check the response once again>>> 
>>> response = client.get('/polls/')>>> response.content'\n\n\n\n\n 
>>>Who is your favorite Beatle?\n
>>> \n\n\n' *Seeing What's up? here too.*
>>> # If the following doesn't work, you probably omitted the call to>>> # 
>>> setup_test_environment() described above>>> 
>>> response.context['latest_question_list'][>> Beatle?>] *Seeing What's up? here too*


Instead of getting '\n\n\nNo polls are available.\n\n' , the What's 
up poll is coming up i.e. b'r\n\t\r\n\t\r\n\t\tWhat'se up?\r\n\t\r\n\t\r\n? The rest of the 
code works fine as in adding the Beatles question but the What's up? question 
is also coming up along with the Beatles question. Is this ok? Any help would 
be greatly appreciated.

Thanks,

Gavin
