How do you mark strings as "Safe" in a view (or the template) in Jinja2?

Question

Typically when you want to mark string output as safe in Jinja2 you do something like this:

{{ output_string|safe() }}

However, what if output_string is always safe? I don't want to repeat myself every time by using the safe filter.

I have a custom filter called "emailize" that preps urls for output in an email. The ampersands always seem to become escaped. Is there a way in my custom filter to mark the output as safe?

Answer 1

Check SafeString, like for example:

from django.utils.safestring import SafeString
...
return context.update({
        'html_string': SafeString(html_string),
})

Answer 2

Use the Markup class:

class jinja2.Markup([string])

Marks a string as being safe for inclusion in HTML/XML output without needing to be escaped.
