在 Jinja2 中禁用自动转义后重新启用自动转义

Question

I'm writing a simple blog using Flask and Jinja2, and I want to use HTML tags in my posts.
So I was disabled the autoescape in my templates like this:

{{ post.body|safe }}

But when I writing something like >>> print() or it's , however I don't want to escape them myself, I want to enable the autoescape again. Is there anything like a HTML tag to do that?

Answer 1

Well, if you want to use HTML in your post.body - then you have to deal with the fact that some symbols have to be escaped in HTML, eg > should be > . The second option is using <pre> . The third option is post-processing the body, so that the code parts like >>> are automatically escaped. For example:

class Post:
    body = "<span><code>>>> print('Hello world')</code></span>"

    @property
    def html_body(self):
        # 1. Locate all <code>...</code> blocks
        # 2. Convert the text in them to proper HTML
        ...
        return processed_body

    # which should return 
    # "<span><code>&gt;&gt;&gt; print(&apos;Hello world&apos;)</code></span>"
