python - How to access session variables in jinja 2 - Flask

Question

Do I need to pass session variables manually from Flask to my HTML or are they automatically sent in some way?

Can I do

return render_template('index.html')

and access a session variable username, for example, like {{session['username'}} in the HTML file?

Answer 1

In python

session['username'] = 'username'

in jinja2 you can go

{{session['username']}}
