在./article/list_views.py中找到article_detail 函数：
```python
def article_detail(request, id, slug):
    article = get_object_or_404(ArticlePost, id=id, slug=slug)
    total_views = r.incr("article:{}:views".format(article.id))
    r.zincrby('article_ranking', 1, article.id)
    
    # 这里控制最受欢迎文章数量
    article_ranking = r.zrange('article_ranking', 0, -1, desc=True)[:10]  # 修改这个数字
    
    article_ranking_ids = [int(id) for id in article_ranking]
    most_viewed = list(ArticlePost.objects.filter(id__in=article_ranking_ids))
    most_viewed.sort(key=lambda x: article_ranking_ids.index(x.id))
    
    # ... 其他代码
	article_tags_ids = article.article_tag.values_list("id", flat=True)
	similar_articles = ArticlePost.objects.filter(article_tag__in=article_tags_ids).exclude(id=article.id)
	similar_articles = similar_articles.annotate(same_tags=Count("article_tag")).order_by('-same_tags', '-created')[:4]
	return render(request, "article/list/article_content.html", {
		"article":article, 
		"total_views":total_views, 
		"most_viewed":most_viewed,
		"comment_form":comment_form,
