two errors in Part 2 of tutorial

[rbarh...@gmail.com]

Here is my code from working on Part 2 of the first Django app

~~~

from django.db import models
from django.utils import timezone
import datetime

# 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, on_delete=models.CASCADE)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
def __str__(self):
return self.choice_text

~~~

I get the following error to the following questions:

~~~

In [9]: Question.objects.filter(question_text_startswith='What')   

FieldError: Cannot resolve keyword 'question_text_startswith' into field. Choices are: choice, id, pub_date, question_text

In [12]: Question.objects.get(pub_date_year=current_year) 

FieldError: Cannot resolve keyword 'pub_date_year' into field. Choices are: choice, id, pub_date, question_text

 q.was_published_recently()  

AttributeError: 'Question' object has no attribute 'pub'

~~~

Plus, I don't understand the "-" in this line:

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

Help, please.  Thank you.

I think the first serious problem is the dash in the "return self.pub_date..." line.  I don't understand at all and now I get a syntax error when I try to restart the shell...

Well, think I got that worked out but I have this problem with timezone, and trying to set the time to current year...

FieldError: Cannot resolve keyword 'pub_date_year' into field. Choices are: choice, id, pub_date, question_text

This doesn't seem to work:

# Get the question that was published this year.

  >>> from django.utils import timezone 

>>> current_year = timezone.now().year
