在 Django 中实现综合浏览量

Question

我正在一个小型网站上工作，我想在详细视图中显示每个 object 的总视图。 但说实话，我不知道如何实现这一点。 让我发布我的 models.py 和 views.py

模型.py

class Music(models.Model):
    artist = models.CharField(max_length=300)
    title = models.CharField(max_length=200, unique=True)
    slug = models.SlugField(default='', blank=True, unique=True)
    thumbnail = models.ImageField(blank=False)
    audio_file = models.FileField(default='')
    uploaded_date = models.DateTimeField(default=timezone.now)

    class Meta:
        ordering = ['-uploaded_date']

    def save(self):
        self.uploaded_date = timezone.now()
        self.slug = slugify(self.title)
        super(Music, self).save()

    def __str__(self):
        return self.title + ' by ' + self.artist

    def get_absolute_url(self):
        return reverse('music:detail', kwargs={'slug': self.slug})

视图.py

        return Music.objects.order_by('-uploaded_date')


def detail(request, slug):
    latest_posts = Music.objects.order_by('-uploaded_date')[:5]
    song = get_object_or_404(Music, slug=slug)
    comments = Comment.objects.filter(post=song)

    if request.method == 'POST':
        comment_form = CommentForm(request.POST or None)
        if comment_form.is_valid():
            comment = comment_form.save(commit=False)
            comment.post = song
            comment.save()
            return HttpResponseRedirect(song.get_absolute_url())
    else:
        comment_form = CommentForm()

    context = {
        'latest_posts': latest_posts,
        'song': song,
        'comments': comments,
        'comment_form': comment_form,
    }
    return render(request, 'music/detail.html', context)

Answer 1

您可以在名为page_views的Music model 中添加一个IntegerField ：

class Music(models.Model):
    ...
    page_views = IntegerField(default=0)

然后从这个答案中借用，您可以在请求页面时从detail views中增加单个song的视图：

def detail(request, slug):
    latest_posts = Music.objects.order_by('-uploaded_date')[:5]
    song = get_object_or_404(Music, slug=slug)
    comments = Comment.objects.filter(post=song)

    if request.method == 'POST':
        comment_form = CommentForm(request.POST or None)
        if comment_form.is_valid():
            comment = comment_form.save(commit=False)
            comment.post = song
            comment.save()
            return HttpResponseRedirect(song.get_absolute_url())
    else:
        comment_form = CommentForm()
        song.update(page_views=F('page_views') + 1) # Add this line here so it's not updated on POST

    context = {
        'latest_posts': latest_posts,
        'song': song,
        'comments': comments,
        'comment_form': comment_form,
    }
    return render(request, 'music/detail.html', context)

请注意，您可能不希望将通过表单添加评论的人计为页面的另一个视图，因此取决于您如何定义计数实际增加的时间。 这只是计算页面被请求次数的一种非常基本的方法。
