如何显示Django中BeautifulSoup解析的结果? [英] How should I show results of BeautifulSoup parsing in Django?

问题描述

我正在尝试使用BeautifulSoup和Django抓取网页.这是执行此任务的views.py:

I'm trying to scrape a web page using BeautifulSoup and Django. Here's my views.py which do this task:

def detail(request, article_id):
    article = get_object_or_404(Article, pk=article_id)
    html = urllib2.urlopen("...url...")
    soup = BeautifulSoup(html)
    title = soup.title

    return render(request, 'detail.html', {'article': article, 'title':title})

但是当我在Django模板文件中使用{{title}}时，它什么也没显示.我已经对其进行了测试，并且可以在Shell中运行.我在此函数中添加了一行:

But when I use {{ title }} in django template files, it doesn't show anything. I've test it and it works in shell. I've added a line to this function:

print soup.title

，并且每次我重新加载页面时都会打印出来，但是它不会显示在模板中.

and it prints it every time I reload the page, but it doesn't show up in templates.

对于其他一些命令，例如find_all("a")或prettify方法，内容也显示出非常奇怪的效果.谁能告诉我如何在Django模板中正确打印beautifulsoup的结果?

The content also displayed very strange for some other commands like: find_all("a") or prettify method. Could anyone tell me how can I print the result of beautifulsoup correctly in django templates?

推荐答案

打印出来的结果是什么?

what's the result that you print out?

您尝试使用它吗?

soup.title.string

如果您必须将html发送到模板中，请尝试:

if you have to send html in to templates try:

{% autoescape off %}{{ title }}{% endautoescape %}
