Allowing  tags with Google App Engine and Jinja2
The easiest way to do this is to escape the field yourself, then add line breaks. When you pass it in in jinja, mark it as safe so it's not autoescaped.
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?
