允许< br> Google App Engine和Jinja2的标签 [英] Allowing <br> tags with Google App Engine and Jinja2

问题描述

在我的网络应用程序中，用户可以创建博客帖子。当我显示博客文章时，换行不会显示，因为我没有用< br> 标签替换新行。问题是我已经在Jinja中自动转义，所以< br> 标签被转义。我不想临时禁用自动转义，我想要具体允许< br> 标签。我该怎么做？

In my web app, the user can make blog posts. When I display the blog post, newlines aren't shown because I didn't replace the new lines with <br> tags. The problem is that I've turned autoescaping on in Jinja, so <br> tags are escaped. I don't want to temporarily disable autoescaping, I want to specifically allow <br> tags. How would I do this?

推荐答案

我有另一个答案，我认为是最好的。最初我只是按照原样显示我的变量 post.content ，并且换行没有被保留。这里的任何一个解决方案都不是很好，而且我的解决方案只是一个快速的解决方案，并且有重大的问题。这是真正的解决方案：

I have another answer that I think is the best. Initially I was just displaying my variable post.content as-is, and the newlines weren't being preserved. None of the solutions here worked (well), and my pre solution was just a quick fix and had major issues. This is the real solution:

{% for line in post.content.splitlines() %}
    {{line}}<br>
{% endfor %}
