How to translate a string in html flask?

Question

Flask

Let's say there are two pages. The first, static, contains a form that is designed to write html files to the database. Here is how the file is processed:

def OneFile(path):
    with io.open(path, 'r') as f:
        content = f.read()
    soup = bs(content, features='lxml')
    content = str(soup.find('body'))[6:-7]
    images = soup.find_all('img')
    if images != []:
        images = list(map(str, list(images)))
        for i in images:
            img = bs(i, features='lxml').find('body').find('img')
            src = img.get('src')
            src2 = f"{{{{ url_for('static' filename='{str(src)}') }}}}"
            img2 = str(img).replace(str(src), str(src2))
            content = content.replace(str(img), img2)
    return content

Everything works great, only there was a problem with the second page.
It is dynamic, and it shows what the function above returns. Actually, it's not hard to guess that instead of html tags, something like this is shown: <h1></h1>.
I solved this problem on the front, namely, I wrote a js script that turns these characters above into html tags. So what is the question, the url_for function does not work because no one told the Python interpreter that these characters are html. How to make it understand and jinja work?

Answer 1

To prevent flask from doing this, you need to use the safe filter.
{{ url_for('static' filename='...')|safe }}
