Здравствуйте.
Есть модель:import datetime
from django.db import models
from django.utils import timezone
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __unicode__(self):
return self.question_text
def was_published_recently(self):
now = timezone.now()
return now - datetime.timedelta(days=1) <= self.pub_date <= now
was_published_recently.admin_order_field = 'pub_date'
was_published_recently.boolean = True
was_published_recently.short_description = 'Published recently?'
class Choice(models.Model):
poll = models.ForeignKey(Question)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField()
def __unicode__(self):
return self.choice_text
Модель описывает вопрос-ответы, за одним вопросом может быть закреплено от 0 до N ответов.
Есть views.py:from django.shortcuts import get_object_or_404, render
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from django.views import generic
from django.utils import timezone
from .models import Choice, Question
class IndexView(generic.ListView):
template_name = 'polls/index.html'
context_object_name = 'latest_question_list'
def get_queryset(self):
"""
Return the last five published questions (not including those set to be
published in the future).
"""
return Question.objects.filter(
pub_date__lte=timezone.now()
).order_by('-pub_date')[:5]
Суть вопроса: Какие параметры указать в Question.objects.filter() чтобы получать только те вопросы, на которые есть варианты ответов?
