Pass HTML to template using Flask / Jinja2

Question

I am creating admin for Flask and SQLAlchemy and I want to pass HTML for different inputs in my opinion using render_template . The template script seems to automatically exit html, so all <"'> are converted to html objects. How do I disable this so that the HTML code displays correctly?

Answer 1

the ideal way is to

 {{ something|safe }} 

Than completely disable auto exposure.

Answer 2

You can also declare it safe HTML from code:

 from flask import Markup value = Markup('<strong>The HTML String</strong>') 

Then pass this value to the templates, and they should not |safe it.

Answer 3

From the Jinja Docs HTML Escape section:

When auto-escaping is enabled, by default all are escaped, except for values ​​explicitly marked as safe. They can be marked with the application or in the template using the filter | safe.

Example:

  <div class="info"> {{data.email_content|safe}} </div> 

Answer 4

If you have many variables that do not need to be escaped, you can use the autoescape block:

 {% autoescape off %} {{ something }} {{ something_else }} <b>{{ something_important }}</b> {% endautoescape %}
