我应该如何在 Django 中显示 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.这是我执行此任务的 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，它没有显示任何内容.我已经测试过了，它在 shell 中工作.我在这个函数中添加了一行:

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

每次我重新加载页面时它都会打印它，但它没有显示在模板中.

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，内容也显示得很奇怪.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

你打印出来的结果是什么?

what's the result that you print out?

你试过用这个吗?

soup.title.string

如果您必须将 html 发送到模板，请尝试:

if you have to send html in to templates try:

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