Question

我正在写一个非常简单的搜索视图：

   @Override
   public void computeScroll() {
       super.computeScroll();
       if (mDragHelper.continueSettling(true)) {
           ViewCompat.postInvalidateOnAnimation(this);
       }
   }

结果应按选择总票数排序：

class SearchView(generic.ListView): template_name = 'polls/search.html' context_object_name = 'results' def get_queryset(self): """ Extract query from parameters and return search results. """ query = self.request.GET.get('query') if query: query = query.strip() return Question.objects.filter(question_text__icontains=query) else: return Question.objects.none() <!DOCTYPE html> {% if results %} <ul> {% for result in results %} <li><a href="{% url 'polls:vote' result.id %}">{{ result }}</a></li> {% endfor %} </ul> {% else %} <p>No matches found.</p> {% endif %} <p><a href="{% url 'polls:index' %}">Back to overview?</a></p>

此查询似乎不起作用并多次返回问题。
如何在多个页面上拆分结果？

Answer 1

如果您附加问题 Django模型，也许它很有用，因为我不了解您的错误。

关于分页，这里有一些我在我的应用程序中使用的有用的Django类：

https://docs.djangoproject.com/en/1.10/topics/pagination/

使用起来非常简单。

谢谢！分页正是我所寻找的。

我想在反向外键关系船上进行查询：

class Question(models.Model):
    question_text = models.CharField('text', max_length=200)
    pub_date = models.DateTimeField('publication date', default=timezone.now)

    def __str__(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):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField('text', max_length=200)
    votes = models.IntegerField('votes', default=0)

    def __str__(self):
        return self.choice_text

解决方案是使用注释：

results.annotate(total_votes=Sum('choice__votes')).order_by('-total_votes')

搜索具有多个页面的视图并按相关性排序
